A textile is a flexible material consisting of a network of natural or artificial fibers (yarn or thread). Yarn is produced by spinning raw fibres of wool, flax, cotton, hemp, or other materials to produce long strands. Textiles are formed by weaving, knitting, crocheting, knotting or tatting, felting, or braiding

The related words "fabric" and "cloth" and "material" are often used in textile assembly trades (such as tailoring and dressmaking) as synonyms for textile. However, there are subtle differences in these terms in specialized usage. A textile is any material made of interlacing fibres, including carpeting and geotextiles. A fabric is a material made through weaving, knitting, spreading, crocheting, or bonding that may be used in production of further goods (garments, etc.). Cloth may be used synonymously with fabric but is often a piece of fabric that has been processed.

Etymology

The word 'textile' is from Latin, from the adjective textilis, meaning 'woven', from textus, the past participle of the verb texere, 'to weave'.

The word 'fabric' also derives from Latin, most recently from the Middle French fabrique, or 'building, thing made', and earlier as the Latin fabrica 'workshop; an art, trade; a skilful production, structure, fabric', which is from the Latin faber, or 'artisan who works in hard materials', from PIE dhabh-, meaning 'to fit together'.

The word 'cloth' derives from the Old English clað, meaning a cloth, woven or felted material to wrap around one, from Proto-Germanic kalithaz (compare O.Frisian 'klath', Middle Dutch 'cleet', Dutch 'kleed', Middle High German 'kleit', and German 'kleid', all meaning "garment").

History

The first clothes, worn at least 70,000 years ago and perhaps much earlier, were probably made of animal skins and helped protect early humans from the ice ages. Then at some point people learned to weave plant fibers into textiles. 

The discovery of dyed flax fibres in a cave in the Republic of Georgia dated to 34,000 BCE suggests textile-like materials were made even in prehistoric times.

The production of textiles is a craft whose speed and scale of production has been altered almost beyond recognition by industrialization and the introduction of modern manufacturing techniques. However, for the main types of textiles, plain weave, twill, or satin weave, there is little difference between the ancient and modern methods.

Uses

Textiles have an assortment of uses, the most common of which are for clothing and for containers such as bags and baskets. In the household they are used in carpeting, upholstered furnishings, window shades, towels, coverings for tables, beds, and other flat surfaces, and in art. In the workplace they are used in industrial and scientific processes such as filtering. Miscellaneous uses include flags, backpacks, tents, nets, handkerchiefs, cleaning rags, transportation devices such as balloons, kites, sails, and parachutes; textiles are also used to provide strengthening in composite materials such as fibreglass and industrial geotextiles. Textiles are used in many traditional crafts such as sewing, quilting and embroidery

Textiles for industrial purposes, and chosen for characteristics other than their appearance, are commonly referred to as technical textiles. Technical textiles include textile structures for automotive applications, medical textiles (e.g. implants), geotextiles (reinforcement of embankments), agrotextiles (textiles for crop protection), protective clothing (e.g. against heat and radiation for fire fighter clothing, against molten metals for welders, stab protection, and bullet proof vests). In all these applications stringent performance requirements must be met. Woven of threads coated with zinc oxide nanowires, laboratory fabric has been shown capable of "self-powering nanosystems" using vibrations created by everyday actions like wind or body movements.

Sources and types

Textiles are made from many materials, with four main sources: animal (wool, silk), plant (cotton, flax, jute, bamboo), mineral (asbestos, glass fibre), and synthetic (nylon, polyester, acrylic, rayon). The first three are natural. In the 20th century, they were supplemented by artificial fibres made from petroleum.

Textiles are made in various strengths and degrees of durability, from the finest microfibre made of strands thinner than one denier to the sturdiest canvas. Textile manufacturing terminology has a wealth of descriptive terms, from light gauze-like gossamer to heavy grosgrain cloth and beyond.

Animal

Animal textiles are commonly made from hair, fur, skin or silk (in the silkworms case).

Wool refers to the hair of the domestic sheep or goat, which is distinguished from other types of animal hair in that the individual strands are coated with scales and tightly crimped, and the wool as a whole is coated with a wax mixture known as lanolin (sometimes called wool grease), which is waterproof and dirtproof. Woollen refers to a bulkier yarn produced from carded, non-parallel fibre, while worsted refers to a finer yarn spun from longer fibres which have been combed to be parallel. Wool is commonly used for warm clothing. Cashmere, the hair of the Indian cashmere goat, and mohair, the hair of the North African angora goat, are types of wool known for their softness. 

Other animal textiles which are made from hair or fur are alpaca wool, vicuña wool, llama wool, and camel hair, generally used in the production of coats, jackets, ponchos, blankets, and other warm coverings. Angora refers to the long, thick, soft hair of the angora rabbit. Qiviut is the fine inner wool of the muskox.

Wadmal is a coarse cloth made of wool, produced in Scandinavia, mostly 1000~1500 CE.

Sea silk is an extremely fine, rare, and valuable fabric that is made from the silky filaments or byssus secreted by a gland in the foot of pen shells. 

Silk is an animal textile made from the fibres of the cocoon of the Chinese silkworm which is spun into a smooth fabric prized for its softness. There are two main types of the silk: 'mulberry silk' produced by the Bombyx Mori, and 'wild silk' such as Tussah silk (wild silk). Silkworm larvae produce the first type if cultivated in habitats with fresh mulberry leaves for consumption, while Tussah silk is produced by silkworms feeding purely on oak leaves. Around four-fifths of the world's silk production consists of cultivated silk.

Plant

Grass, rush, hemp, and sisal are all used in making rope. In the first two, the entire plant is used for this purpose, while in the last two, only fibres from the plant are utilized. Coir (coconut fibre) is used in making twine, and also in floormats, doormats, brushes, mattresses, floor tiles, and sacking.

Straw and bamboo are both used to make hats. Straw, a dried form of grass, is also used for stuffing, as is kapok.

Fibres from pulpwood trees, cotton, rice, hemp, and nettle are used in making paper.

Cotton, flax, jute, hemp, modal and even bamboo fibre are all used in clothing. Piña (pineapple fibre) and ramie are also fibres used in clothing, generally with a blend of other fibres such as cotton. Nettles have also been used to make a fibre and fabric very similar to hemp or flax. The use of milkweed stalk fibre has also been reported, but it tends to be somewhat weaker than other fibres like hemp or flax. 

The inner bark of the lacebark tree is a fine netting that has been used to make clothing and accessories as well as utilitarian articles such as rope. 

Acetate is used to increase the shininess of certain fabrics such as silks, velvets, and taffetas

Seaweed is used in the production of textiles: a water-soluble fibre known as alginate is produced and is used as a holding fibre; when the cloth is finished, the alginate is dissolved, leaving an open area.
Rayon is a manufactured fabric derived from plant pulp. Different types of rayon can imitate the feel and texture of silk, cotton, wool, or linen. 

Fibres from the stalks of plants, such as hemp, flax, and nettles, are also known as 'bast' fibres.

Mineral

Asbestos and basalt fibre are used for vinyl tiles, sheeting and adhesives, "transite" panels and siding, acoustical ceilings, stage curtains, and fire blankets. 

Glass fibre is used in the production of ironing board and mattress covers, ropes and cables, reinforcement fibre for composite materials, insect netting, flame-retardant and protective fabric, soundproof, fireproof, and insulating fibres. Glass fibres are woven and coated with Teflon to produce beta cloth, a virtually fireproof fabric which replaced nylon in the outer layer of United States space suits since 1968.

Metal fibre, metal foil, and metal wire have a variety of uses, including the production of cloth-of-gold and jewellery. Hardware cloth (US term only) is a coarse woven mesh of steel wire, used in construction. It is much like standard window screening, but heavier and with a more open weave.

Minerals and natural and synthetic fabrics may be combined, as in emery cloth, a layer of emery abrasive glued to a cloth backing. Also, "sand cloth" is a U.S. term for fine wire mesh with abrasive glued to it, employed like emery cloth or coarse sandpaper.

Synthetic

Synthetic textiles are used primarily in the production of clothing, as well as the manufacture of geotextiles.

Polyester fibre is used in all types of clothing, either alone or blended with fibres such as cotton.

Aramid fibre (e.g. Twaron) is used for flame-retardant clothing, cut-protection, and armour.

Acrylic is a fibre used to imitate wools, including cashmere, and is often used in replacement of them.

Nylon is a fibre used to imitate silk; it is used in the production of pantyhose. Thicker nylon fibres are used in rope and outdoor clothing.

Spandex (trade name Lycra) is a polyurethane product that can be made tight-fitting without impeding movement. It is used to make activewear, bras, and swimsuits.

Olefin fibre is a fibre used in activewear, linings, and warm clothing. Olefins are hydrophobic, allowing them to dry quickly. A sintered felt of olefin fibres is sold under the trade name Tyvek.

Ingeo is a polylactide fibre blended with other fibres such as cotton and used in clothing. It is more hydrophilic than most other synthetics, allowing it to wick away perspiration.

Lurex is a metallic fibre used in clothing embellishment.

Milk proteins have also been used to create synthetic fabric. Milk or casein fibre cloth was developed during World War I in Germany, and further developed in Italy and America during the 1930s. Milk fibre fabric is not very durable and wrinkles easily, but has a pH similar to human skin and possesses anti-bacterial properties. It is marketed as a biodegradable, renewable synthetic fibre.

Carbon fibre is mostly used in composite materials, together with resin, such as carbon fibre reinforced plastic. The fibres are made from polymer fibres through carbonization.

Weaving is a textile production method which involves interlacing a set of longer threads (called the warp) with a set of crossing threads (called the weft). This is done on a frame or machine known as a loom, of which there are a number of types. Some weaving is still done by hand, but the vast majority is mechanized.

Knitting, looping, and crocheting involve interlacing loops of yarn, which are formed either on a knitting needle, needle, or on a crochet hook, together in a line. The processes are different in that knitting has several active loops at one time, on the knitting needle waiting to interlock with another loop, while Looping and crocheting never have more than one active loop on the needle. Knitting can be performed by machine, but crochet can only be performed by hand.

Spread Tow is a production method where the yarn are spread into thin tapes, and then the tapes are woven as warp and weft. This method is mostly used for composite materials; spread tow fabrics can be made in carbon, aramide, etc. 

Braiding or plaiting involves twisting threads together into cloth. Knotting involves tying threads together and is used in making tatting and macrame

Lace is made by interlocking threads together independently, using a backing and any of the methods described above, to create a fine fabric with open holes in the work. Lace can be made by either hand or machine. 

Carpets, rugs, velvet, velour, and velveteen are made by interlacing a secondary yarn through woven cloth, creating a tufted layer known as a nap or pile

Felting involves pressing a mat of fibres together, and working them together until they become tangled. A liquid, such as soapy water, is usually added to lubricate the fibres, and to open up the microscopic scales on strands of wool. 

Nonwoven textiles are manufactured by the bonding of fibres to make fabric. Bonding may be thermal or mechanical, or adhesives can be used. 

Bark cloth is made by pounding bark until it is soft and flat.

Treatments

Textiles are often dyed, with fabrics available in almost every colour. The dyeing process often requires several dozen gallons of water for each pound of clothing.[19] Coloured designs in textiles can be created by weaving together fibres of different colours (tartan or Uzbek Ikat), adding coloured stitches to finished fabric (embroidery), creating patterns by resist dyeing methods, tying off areas of cloth and dyeing the rest (tie-dyeing), or drawing wax designs on cloth and dyeing in between them (batik), or using various printing processes on finished fabric. Woodblock printing, still used in India and elsewhere today, is the oldest of these dating back to at least 220 CE in China. Textiles are also sometimes bleached, making the textile pale or white.

Textiles are sometimes finished by chemical processes to change their characteristics. In the 19th century and early 20th century starching was commonly used to make clothing more resistant to stains and wrinkles. 

Eisengarn, meaning "iron yarn" in English, is a light-reflecting, strong material invented in Germany in the 19th century. It is made by soaking cotton threads in a starch and paraffin wax solution. The threads are then stretched and polished by steel rollers and brushes. The end result of the process is a lustrous, tear-resistant yarn which is extremely hardwearing.

Since the 1990s, with advances in technologies such as permanent press process, finishing agents have been used to strengthen fabrics and make them wrinkle free. More recently, nanomaterials research has led to additional advancements, with companies such as Nano-Tex and NanoHorizons developing permanent treatments based on metallic nanoparticles for making textiles more resistant to things such as water, stains, wrinkles, and pathogens such as bacteria and fungi.

Textiles receive a range of treatments before they reach the end-user. From formaldehyde finishes (to improve crease-resistance) to biocidic finishes and from flame retardants to dyeing of many types of fabric, the possibilities are almost endless. However, many of these finishes may also have detrimental effects on the end user. A number of disperse, acid and reactive dyes (for example) have been shown to be allergenic to sensitive individuals. Further to this, specific dyes within this group have also been shown to induce purpuric contact dermatitis.

Although formaldehyde levels in clothing are unlikely to be at levels high enough to cause an allergic reaction, due to the presence of such a chemical, quality control and testing are of utmost importance. Flame retardants (mainly in the brominated form) are also of concern where the environment, and their potential toxicity, are concerned. Testing for these additives is possible at a number of commercial laboratories, it is also possible to have textiles tested for according to the Oeko-tex certification standard which contains limits levels for the use of certain chemicals in textiles products.

Clothing

From Wikipedia, the free encyclopedia
 
Clothing in history, showing (from top) Egyptians, Ancient Greeks, Romans, Byzantines, Franks, and 13th through 15th century Europeans.
 
Clothing (also known as clothes, apparel and attire) is a collective term for items worn on the body. Clothing is typically made of fabrics or textiles but over time has included garments made from animal skin or other thin sheets of materials put together. The wearing of clothing is mostly restricted to human beings and is a feature of all human societies. The amount and type of clothing worn depends on gender, body type, social, and geographic considerations.

Clothing serves many purposes: it can serve as protection from the elements, rough surfaces, rash-causing plants, insect bites, splinters, thorns and prickles by providing a barrier between the skin and the environment. Clothes can insulate against cold or hot conditions, and they can provide a hygienic barrier, keeping infectious and toxic materials away from the body. Clothing also provides protection from ultraviolet radiation

Wearing clothes is also a social norm, and being deprived of clothing in front of others may be embarrassing. Not wearing clothes in public so that genitals, breasts or buttocks are visible could be considered indecent exposure.

Origin of clothing

There is no easy way to determine when clothing was first developed, but some information has been inferred by studying lice which estimates the introduction of clothing roughly 42,000–72,000 years ago.

Functions

The most obvious function of clothing is to protect the wearer from the elements. In hot weather, clothing provides protection from sunburn or wind damage. In the cold it offers thermal insulation. Shelter can reduce the functional need for clothing. For example, coats, hats, gloves and other outer layers are normally removed when entering a warm place. Similarly, clothing has seasonal and regional aspects, so that thinner materials and fewer layers of clothing are generally worn in warmer regions and seasons than in colder ones.

Clothing performs a range of social and cultural functions, such as individual, occupational and gender differentiation, and social status. In many societies, norms about clothing reflect standards of modesty, religion, gender, and social status. Clothing may also function as adornment and an expression of personal taste or style. 

Clothing has been made from a very wide variety of materials, ranging from leather and furs to woven fabrics to elaborate and exotic natural and synthetic fabrics. Not all body coverings are regarded as clothing. Articles carried rather than worn (such as purses), worn on a single part of the body and easily removed (scarves), worn purely for adornment (jewelry), or those that serve a function other than protection (eyeglasses), are normally considered accessories rather than clothing.
Clothing protects against many things that might injure or irritate the uncovered human body, including rain, snow, wind, and other weather, as well as from the sun. Garments that are too sheer, thin, small or tight offer less protection. Appropriate clothes can also reduce risk during activities such as work or sport. Some clothing protects from specific hazards, such as insects, noxious chemicals, weather, weapons, and contact with abrasive substances. 

Humans have devised clothing solutions to environmental or other hazards: such as space suits, air conditioned clothing, armor, diving suits, swimsuits, bee-keeper gear, motorcycle leathers, high-visibility clothing, and other pieces of protective clothing. The distinction between clothing and protective equipment is not always clear-cut, since clothes designed to be fashionable often have protective value and clothes designed for function often consider fashion in their design. The choice of clothes also has social implications. They cover parts of the body that social norms require to be covered, act as a form of adornment, and serve other social purposes. Someone who lacks the means to procure reasonable clothing due to poverty or affordability, or simply lack of inclination, is sometimes said to be scruffy, ragged, or shabby.

Scholarship

Serious books on clothing and its functions appear from the 19th century as imperialists dealt with new environments such as India and the tropics. Some scientific research into the multiple functions of clothing in the first half of the 20th century, with publications such as J.C. Flügel's Psychology of Clothes in 1930, and Newburgh's seminal Physiology of Heat Regulation and The Science of Clothing in 1949. By 1968, the field of environmental physiology had advanced and expanded significantly, but the science of clothing in relation to environmental physiology had changed little. There has since been considerable research, and the knowledge base has grown significantly, but the main concepts remain unchanged, and indeed Newburgh's book is still cited by contemporary authors, including those attempting to develop thermoregulatory models of clothing development.

Cultural aspects

Gender differentiation

In most cultures, gender differentiation of clothing is considered appropriate. The differences are in styles, colors, fabrics and types.

In Western societies, skirts, dresses and high-heeled shoes are usually seen as women's clothing, while neckties are usually seen as men's clothing. Trousers were once seen as exclusively male clothing, but can nowadays be worn by both genders. Male clothes are often more practical (that is, they can function well under a wide variety of situations), but a wider range of clothing styles are available for females. Males are typically allowed to bare their chests in a greater variety of public places. It is generally acceptable for a woman to wear clothing perceived as masculine, while the opposite is seen as unusual.

In some cultures, sumptuary laws regulate what men and women are required to wear. Islam requires women to wear more modest forms of attire, usually hijab. What qualifies as "modest" varies in different Muslim societies. However, women are usually required to cover more of their bodies than men are. Articles of clothing Muslim women wear for modesty range from the head-scarf to the burqa

Men may sometimes choose to wear men's skirts such as togas or kilts in particular cultures, especially on ceremonial occasions. Such garments were (in previous times) often worn as normal daily clothing by men.

Clothing designed to be worn by either sex is called unisex clothing. Unisex clothes, such as T-shirts, tend to be cut straighter to fit a wider variety of bodies. The majority of unisex clothing styles have started out as menswear, but some articles, like the fedora, were originally worn by women.

Social status

In some societies, clothing may be used to indicate rank or status. In ancient Rome, for example, only senators could wear garments dyed with Tyrian purple. In traditional Hawaiian society, only high-ranking chiefs could wear feather cloaks and palaoa, or carved whale teeth. In China, before establishment of the republic, only the emperor could wear yellow. History provides many examples of elaborate sumptuary laws that regulated what people could wear. In societies without such laws, which includes most modern societies, social status is instead signaled by the purchase of rare or luxury items that are limited by cost to those with wealth or status. In addition, peer pressure influences clothing choice.

Religion

Some religious clothing might be considered a special case of occupational clothing. Sometimes it is worn only during the performance of religious ceremonies. However, it may also be worn every day as a marker for special religious status.

For example, Jains and Muslim men wear unstitched cloth pieces when performing religious ceremonies. The unstitched cloth signifies unified and complete devotion to the task at hand, with no digression.[citation needed] Sikhs wear a turban as it is a part of their religion.

The cleanliness of religious dresses in some religions such as Hinduism, Sikhism, Buddhism, Islam and Jainism is of paramount importance since it indicates purity. 

Clothing appears in numerous contexts in the Bible; the most prominent passages are: the story of Adam and Eve who made coverings for themselves out of fig leaves, Joseph's cloak, Judah and Tamar, Mordecai and Esther. Furthermore, the priests officiating in the Temple in Jerusalem had very specific garments, the lack of which made one liable to death.

The Quran says about husbands and wives, regarding clothing: "...They are clothing/covering (Libaas) for you; and you for them" (chapter 2:187). 

Jewish ritual also requires rending of one's upper garment as a sign of mourning.

Origin and history

Early use

According to archaeologists and anthropologists, the earliest clothing likely consisted of fur, leather, leaves, or grass that were draped, wrapped, or tied around the body. Knowledge of such clothing remains inferential, since clothing materials deteriorate quickly compared to stone, bone, shell and metal artifacts. Archeologists have identified very early sewing needles of bone and ivory from about 30,000 BC, found near Kostenki, Russia in 1988. Dyed flax fibers that could have been used in clothing have been found in a prehistoric cave in the Republic of Georgia that date back to 34,000 BC.

Scientists are still debating when people started wearing clothes. Ralf Kittler, Manfred Kayser and Mark Stoneking, anthropologists at the Max Planck Institute for Evolutionary Anthropology, have conducted a genetic analysis of human body lice that suggests clothing originated around 170,000 years ago. Body lice are an indicator of clothes-wearing, since most humans have sparse body hair, and lice thus require human clothing to survive. Their research suggests that the invention of clothing may have coincided with the northward migration of modern Homo sapiens away from the warm climate of Africa, thought to have begun between 50,000 and 100,000 years ago. However, a second group of researchers using similar genetic methods estimate that clothing originated around 540,000 years ago. For now, the date of the origin of clothing remains unresolved.

Making clothing

Sari

Some human cultures, such as the various peoples of the Arctic Circle, traditionally make their clothing entirely of prepared and decorated furs and skins. Other cultures supplemented or replaced leather and skins with cloth: woven, knitted, or twined from various animal and vegetable fibers including wool, linen, cotton, silk, hemp, and ramie

Although modern consumers may take the production of clothing for granted, making fabric by hand is a tedious and labor-intensive process involving fiber making, spinning, and weaving. The textile industry was the first to be mechanized – with the powered loom – during the Industrial Revolution.

Different cultures have evolved various ways of creating clothes out of cloth. One approach simply involves draping the cloth. Many people wore, and still wear, garments consisting of rectangles of cloth wrapped to fit – for example, the dhoti for men and the sari for women in the Indian subcontinent, the Scottish kilt and the Javanese sarong. The clothes may simply be tied up (dhoti and sari); or pins or belts hold the garments in place (kilt and sarong). The cloth remains uncut, and people of various sizes can wear the garment.

Another approach involves measuring, cutting, and sewing the cloth by hand or with a sewing machine. Clothing can be cut from a sewing pattern and adjusted by a tailor to the wearer's measurements. An adjustable sewing mannequin or dress form is used to create form-fitting clothing. If the fabric is expensive, the tailor tries to use every bit of the cloth rectangle in constructing the clothing; perhaps cutting triangular pieces from one corner of the cloth, and adding them elsewhere as gussets. Traditional European patterns for men's shirts and women's chemises take this approach. These remnants can also be reused to make patchwork hats, vests, and skirts. 

Modern European fashion treats cloth much less conservatively, typically cutting in such a way as to leave various odd-shaped cloth remnants. Industrial sewing operations sell these as waste; home sewers may turn them into quilts.

In the thousands of years that humans have been making clothing, they have created an astonishing array of styles, many of which have been reconstructed from surviving garments, photos, paintings, mosaics, etc., as well as from written descriptions. Costume history can inspire current fashion designers, as well as costumiers for plays, films, television, and historical reenactment.

Contemporary clothing

Western dress code

The Western dress code has changed over the past 500+ years. The mechanization of the textile industry made many varieties of cloth widely available at affordable prices. Styles have changed, and the availability of synthetic fabrics has changed the definition of "stylish". In the latter half of the 20th century, blue jeans became very popular, and are now worn to events that normally demand formal attire. Activewear has also become a large and growing market. 

Jeans in the Western dress code are worn by both men and women. There are several unique styles of jeans found which include: high rise jeans, mid rise jeans, low rise jeans, bootcut jeans, straight jeans, cropped jeans, skinny jeans, cuffed jeans, boyfriend jeans, and capri jeans.

The licensing of designer names was pioneered by designers like Pierre Cardin in the 1960s and has been a common practice within the fashion industry from about the 1970s. Among the more popular include Marc Jacobs and Gucci, named for Marc Jacobs and Guccio Gucci respectively.

Spread of western styles

By the early years of the 21st century, western clothing styles had, to some extent, become international styles. This process began hundreds of years earlier, during the periods of European colonialism. The process of cultural dissemination has perpetuated over the centuries as Western media corporations have penetrated markets throughout the world, spreading Western culture and styles. Fast fashion clothing has also become a global phenomenon. These garments are less expensive, mass-produced Western clothing. Donated used clothing from Western countries are also delivered to people in poor countries by charity organizations.

Ethnic and cultural heritage

People may wear ethnic or national dress on special occasions or in certain roles or occupations. For example, most Korean men and women have adopted Western-style dress for daily wear, but still wear traditional hanboks on special occasions, like weddings and cultural holidays. Items of Western dress may also appear worn or accessorized in distinctive, non-Western ways. A Tongan man may combine a used T-shirt with a Tongan wrapped skirt, or tupenu.

Sport and activity

Most sports and physical activities are practiced wearing special clothing, for practical, comfort or safety reasons. Common sportswear garments include shorts, T-shirts, tennis shirts, leotards, tracksuits, and trainers. Specialized garments include wet suits (for swimming, diving or surfing), salopettes (for skiing) and leotards (for gymnastics). Also, spandex materials are often used as base layers to soak up sweat. Spandex is also preferable for active sports that require form fitting garments, such as volleyball, wrestling, track & field, dance, gymnastics and swimming.

Fashion shows are often the source of the latest trends in clothing fashions. Photo of a model in a modern gown reflecting the current fashion trend at a Haute couture fashion show.

Fashion

Paris set the fashion trends for Europe and North America 1900–1940. In the 1920s the goal was all about getting loose. Women wore dresses all day, everyday. Day dresses had a drop waist, which was a sash or belt around the low waist or hip and a skirt that hung anywhere from the ankle on up to the knee, never above. Daywear had sleeves (long to mid-bicep) and a skirt that was straight, pleaded, hank hem, or tired. Jewelry was less conspicuous. Hair was often bobbed, giving a boyish look.

In the 21st century a diverse range of styles exist in fashion, varying by geography, exposure to modern media, economic conditions, and ranging from expensive haute couture to traditional garb, to thrift store grunge. Fashion shows are events for designers to show off new and often extravagant designs.

Political issues

Working conditions in the garments industry

Safety garb for women workers in Los Angeles, c. 1943, was designed to prevent occupational accidents among female war workers.
 
Although mechanization transformed most aspects of human industry by the mid-20th century, garment workers have continued to labor under challenging conditions that demand repetitive manual labor. Mass-produced clothing is often made in what are considered by some to be sweatshops, typified by long work hours, lack of benefits, and lack of worker representation. While most examples of such conditions are found in developing countries, clothes made in industrialized nations may also be manufactured similarly.

Coalitions of NGOs, designers (including Katharine Hamnett, American Apparel, Veja, Quiksilver, eVocal, and Edun) and campaign groups like the Clean Clothes Campaign (CCC) and the Institute for Global Labour and Human Rights as well as textile and clothing trade unions have sought to improve these conditions as much as possible by sponsoring awareness-raising events, which draw the attention of both the media and the general public to the workers.

Outsourcing production to low wage countries like Bangladesh, China, India, Indonesia, Pakistan and Sri Lanka became possible when the Multi Fibre Agreement (MFA) was abolished. The MFA, which placed quotas on textiles imports, was deemed a protectionist measure.[citation needed] Although many countries recognize treaties like the International Labour Organization, which attempt to set standards for worker safety and rights, many countries have made exceptions to certain parts of the treaties or failed to thoroughly enforce them. India for example has not ratified sections 87 and 92 of the treaty.

Despite the strong reactions that "sweatshops" evoked among critics of globalization, the production of textiles has functioned as a consistent industry for developing nations providing work and wages, whether construed as exploitative or not, to many thousands of people.

Fur

The use of animal fur in clothing dates to prehistoric times. It is currently associated in developed countries with expensive, designer clothing, although fur is still used by indigenous people in arctic zones and higher elevations for its warmth and protection. Once uncontroversial, it has recently been the focus of campaigns on the grounds that campaigners consider it cruel and unnecessary. PETA, along with other animal rights and animal liberation groups have called attention to fur farming and other practices they consider cruel.

Life cycle

Clothing maintenance

Clothing suffers assault both from within and without. The human body sheds skin cells and body oils, and exudes sweat, urine, and feces. From the outside, sun damage, moisture, abrasion, and dirt assault garments. Fleas and lice can hide in seams. Worn clothing, if not cleaned and refurbished, itches, becomes outworn, and loses functionality (as when buttons fall off, seams come undone, fabrics thin or tear, and zippers fail). 

Often, people wear an item of clothing until it falls apart. Some materials present problems. Cleaning leather is difficult, and bark cloth (tapa) cannot be washed without dissolving it. Owners may patch tears and rips, and brush off surface dirt, but materials like these inevitably age.

However, most clothing consists of cloth, and most cloth can be laundered and mended (patching, darning, but compare felt).

Laundry, ironing, storage

Humans have developed many specialized methods for laundering, ranging from early methods of pounding clothes against rocks in running streams, to the latest in electronic washing machines and dry cleaning (dissolving dirt in solvents other than water). Hot water washing (boiling), chemical cleaning and ironing are all traditional methods of sterilizing fabrics for hygiene purposes.

Many kinds of clothing are designed to be ironed before they are worn to remove wrinkles. Most modern formal and semi-formal clothing is in this category (for example, dress shirts and suits). Ironed clothes are believed to look clean, fresh, and neat. Much contemporary casual clothing is made of knit materials that do not readily wrinkle, and do not require ironing. Some clothing is permanent press, having been treated with a coating (such as polytetrafluoroethylene) that suppresses wrinkles and creates a smooth appearance without ironing. 

Once clothes have been laundered and possibly ironed, they are usually hung on clothes hangers or folded, to keep them fresh until they are worn. Clothes are folded to allow them to be stored compactly, to prevent creasing, to preserve creases or to present them in a more pleasing manner, for instance when they are put on sale in stores.

Certain types of insects and larvae feed on clothing and textiles, such as the Black carpet beetle and Clothing moths. To deter such pests, clothes may be stored in cedar-lined closets or chests, or placed in drawers or containers with materials having pest repellent properties, such as Lavender or mothballs. Airtight containers (such as sealed, heavy-duty plastic bags) may also deter insect pest damage to clothing materials.

Non-iron

A resin used for making non-wrinkle shirts releases formaldehyde, which could cause contact dermatitis for some people; no disclosure requirements exist, and in 2008 the U.S. Government Accountability Office tested formaldehyde in clothing and found that generally the highest levels were in non-wrinkle shirts and pants. In 1999, a study of the effect of washing on the formaldehyde levels found that after 6 months after washing, 7 of 27 shirts had levels in excess of 75 ppm, which is a safe limit for direct skin exposure.

Mending

When the raw material – cloth – was worth more than labor, it made sense to expend labor in saving it. In past times, mending was an art. A meticulous tailor or seamstress could mend rips with thread raveled from hems and seam edges so skillfully that the tear was practically invisible. Today clothing is considered a consumable item. Mass-manufactured clothing is less expensive than the labor required to repair it. Many people buy a new piece of clothing rather than spend time mending. The thrifty still replace zippers and buttons and sew up ripped hems.

Recycling

Used, unwearable clothing can be repurposed for quilts, rags, rugs, bandages, and many other household uses. It can also be recycled into paper. In Western societies, used clothing is often thrown out or donated to charity (such as through a clothing bin). It is also sold to consignment shops, dress agencies, flea markets, and in online auctions. Used clothing is also often collected on an industrial scale to be sorted and shipped for re-use in poorer countries. Globally, used clothes are worth $4 billion with the US as the leading exporter at $575 million.

There are many concerns about the life cycle of synthetics, which come primarily from petrochemicals. Unlike natural fibers, their source is not renewable and they are not biodegradable.

Excess inventory of clothing is sometimes destroyed to preserve brand value.
