Denim is a sturdy cotton warp-facedtextile in which the weft passes under two or more warp threads. This twill weaving produces a diagonal ribbing that distinguishes it from cotton duck. While a denim predecessor known as dungaree has been produced in India for hundreds of years, denim itself was first produced in the French city of Nîmes under the name “serge de Nîmes”.
The most common denim is indigo denim, in which the warp thread is dyed, while the weft thread is left white. As a result of the warp-faced twill weaving, one side of the textile is dominated by the blue warp threads and the other side is dominated by the white weft threads. This causes blue jeans to be white on the inside. The indigo dyeing process, in which the core of the warp threads remains white, creates denim's signature fading characteristics.

Denim was traditionally colored blue with indigo dye to make blue jeans, although "jean" formerly denoted a different lighter, cotton fabric. The contemporary use of the word "jeans" comes from the French word for Genoa, Italy: Gênes.
Denim has been used in the United States since the mid-19th century. Denim initially gained popularity in 1873 when Jacob W. Davis, a tailor from Nevada, manufactured the first pair of rivet-reinforced denim pants. At this time, clothes for Western labourers, such as teamsters, surveyors, and miners, were not very durable. His concept for making reinforced jeans was inspired when a customer requested a pair of durable and strong pants for her husband to chop wood. When Davis was about to finish making the denim jeans, he saw some copper rivets lying on a table and used the rivets to fasten the pockets. Soon, the popularity of denim jeans began to spread rapidly, and Davis was overwhelmed with requests. He soon sold 200 pairs to workers in need of heavy work clothing. Nevertheless, because of the production capacity in his small shop, Davis was struggling to keep up with the demand. He then wrote a proposal to dry goods wholesaler Levi Strauss & Co. that had been supplying Davis with bolts of denim fabric. Davis's proposal was to patent the design of the rivet-reinforced denim pant, with Davis listed as inventor, in exchange for certain rights of manufacture. Levi Strauss & Co. was so impressed by the possibilities for profit in the manufacture of the garment that they then hired Davis to be in charge of the mass production in San Francisco.
Throughout the 20th century denim was used for cheap durable uniforms like those issued to staff of the French national railways.[better source needed] In the postwar years, Royal Air Force overalls for dirty work were named "denims." These were a one-piece garment, with long legs and sleeves, buttoned from throat to crotch, in an olive drab denim fabric.
All denim is created through generally the same process:
- Cotton is harvested by hand or machine.
- A cotton gin separates the cotton fiber from the seeds.
- The cotton fiber is spun into yarn.
- The yarn is dyed.
- The dyed yarn is woven on a shuttle loom or projectile loom.
- The woven product is sanforized.
Most denim yarn is composed entirely of cotton. Some denim yarn may use an elastic component such as spandex for up to 3% of the content to allow the final woven product to stretch. Even such a small amount of spandex enables a stretching capacity of about 15%.
Denim was originally dyed with indigo dye extracted from plants, often from the Indigofera family. In South Asia, indigo dye was extracted from the dried and fermented leaves of Indigofera tinctoria; this is the plant that is now known as "true indigo" or "natural indigo". In Europe, use of Isatis tinctoria, or woad, can be traced back to the eighth century BC, although it was eventually replaced by Indigofera tinctoria as the superior dye product. However, most denim today is dyed with synthetic indigo dye. In all cases, the yarn undergoes a repeated sequence of dipping and oxidation — the more dips, the stronger the color of the indigo.
Prior to 1915, cotton yarns were dyed using a skein dyeing process, in which individual skeins of yarn were dipped into dye baths. Rope dyeing machines were developed in 1915, and slasher or sheet dyeing machines were developed in the 1970s; both of these methods involve a series of rollers that feed continuous yarns in and out of dye vats. In rope dyeing, continuous yarns are gathered together into long ropes or groups of yarns – after these bundles are dyed, they must be re-beamed for weaving. In sheet dyeing, parallel yarns are laid out as a sheet, in the same order in which they will be woven; because of this, uneven circulation of dye in the dye bath can lead to side-to-side color variations in the woven cloth. Rope dyeing eliminates this possibility, because color variations can be evenly distributed across the warp during beaming.
Denim fabric dyeing is divided into two categories: indigo dyeing and sulfur dyeing. Indigo dyeing produces the traditional blue color or shades similar to it. Sulfur dyeing produces speciality black colors and other colors, such as red, pink, purple, grey, rust, mustard, and green.
Most denim made today is made on a shuttleless Sulzer looms that produces bolts of fabric 60 inches or wider, but some denim is still woven on the traditional shuttle loom, which typically produces a bolt 30 inches wide. Shuttle-loom-woven denim is typically recognizable by its selvedge (or selvage), the edge of a fabric created as a continuous cross-yarn (the weft) reverses direction at the edge side of the shuttle loom. The selvedge is traditionally accentuated with warp threads of one or more contrasting colors, which can serve as an identifying mark.
Although quality denim can be made on either loom, selvedge denim has come to be associated with premium products since final production that showcases the selvedge requires greater care of assemblage.[promotional source?]
The thickness of denim can vary greatly, with a yard of fabric weighing anywhere from 9 to 24 oz, with 11 to 14 oz being typical.
Particularly with denim jeans, a significant amount of the æsthetic treatment of denim occurs after the denim has been cut and sewn into the final garment.
Many denim articles are washed to make them softer and to reduce or minimize shrinkage even beyond what sanforization prevents. Significantly washed denim can resemble dry denim which has faded naturally over extended use. Such distressing may be supplemented by chemical treatments or physical techniques such as stone washing.
Changes in appearance due to useEdit
Over time dry denim will fade, considered fashionable in some circumstances. During the process of wear, fading will usually occur on those parts of the article that receive the most stress. On a pair of jeans, this includes the upper thighs, the ankles, and the areas behind the knees.
To facilitate the natural distressing process, some wearers of dry denim will abstain from washing their jeans for more than six months. Most dry denim is made with 100% cotton and comes from several different countries.
Patterns of fading in jeans caused by prolonged periods of wearing them without washing are a way of "personalizing" the garment. Such patterns include:
- honeycombs – meshes of faded line-segments that form behind the knees
- whiskers – faded streaks that form radially from the crotch area
- stacks – irregular bands of fading above the ankle caused by according of the fabric due to contact with the foot or shoe
- train tracks – fading along the out-seams due to abrasion
As jeans grew in popularity in the early 1970s, "one of the most creative carmakers of the era, AMC, took note." Starting with the 1973 model year, American Motors (AMC) offered a regular production option consisting of a Levi's interior trim package. American Motors had an objective of offering fashion interiors for its cars and the Levi's trim was "designed to appeal to young men and women who enjoy the casual look in clothes and cars. Over the years it was available on the Gremlin, Hornet, and Pacer.
Although the car's jean material looks just like the real thing, AMC used spun nylon that was made to imitate denim. This was because real denim fabric is not tough enough for automobile use and cannot pass fire resistance safety standards. The copper rivets were the actual versions and the seat design included traditional contrasting stitching with the Levi's tab on both the front seat backs. The option also included unique door panels with Levis trim and removable map pockets, as well as "Levi's" decal identification on the front fenders. The Levi's trim package option was $134.95, but only $49.95 extra if ordered together with the "Gremlin X" appearance option. The Levi's interior upholstery was available through the 1978 model year AMC Gremlin. It has become one of the best-known options on the Gremlins.
A Levi's trim package was also available by AMC on most Jeeps, including the CJ series, the full-size Cherokee (SJ), and the J series pickup trucks from 1975 through 1977. This consisted of denim-colored-and-textured vinyl upholstery and a matching canvas top. This option was available on all CJ models in blue or tan, and was the standard trim on the top-level Renegade versions. The Levi's association was removed in later years with the upholstery trim named "Denim vinyl" through 1980.
British artist Ian Berry has been making art with only denim for well over a decade. and is famed around the world for his photorealistic pieces all hand cut out of only denim of portraits and scenes. He has made pieces of Ayrton Senna,Giorgio Armani,Lapo Elkann,Debbie Harry,Jenifer Saunders, Eunice Olumbide OBE among others. In 2013, he was named as one of the top 30 Artists under 30 in the World by Art Business News.
Many everyday people from around the world have taken to creating art on their denim, often using fabric paint or acrylic to add a personal touch and express themselves further in their clothing.
In 2007, the worldwide denim market equalled 51.6 billion U.S. dollars , with demand growing by 5% and supply growing by 8% annually. Over 50% of denim is produced in Asia, most of it in China, India, Turkey, Pakistan, and Bangladesh.
Globally, the denim industry is expected to grow at a CAGR of over 6.5% during 2015 to 2020, with the market value expected to increase from 113 billion dollars to 153 billion dollars .
