Denim as used for blue jeans, with a copper rivet to strengthen the pocket.
'Denim', in American usage since the late eighteenth century,
[1] denotes a rugged
cotton twill textile, in which the
weft passes under two (''twi-'' "double") or more
warp fibers, producing the familiar diagonal ribbing identifiable on the reverse of the fabric, which distinguishes denim from
cotton duck. A popular conception of the etymology of the word denim is that it is a contraction or derivative of the French term, ''serge de
Nîmes.''
[2] Denim was traditionally colored blue with
indigo dye to make blue "
jeans," though "jean" then denoted a different, lighter cotton textile; the contemporary use of jean comes from the French word for
Genoa,
Italy (Gênes), from which the first denim trousers were made.
A similarly woven traditional American cotton textile is the diagonal warp-striped hickory cloth that was once associated with railroadmen's overalls, in which blue or black contrasting with undyed white threads form the woven pattern. Hickory cloth was characterized as being as rugged as
hickory wood—not to mention the fact that it was deemed to be worn mainly by "hicks"—although neither may be the origin of that term [from a nickname for "Richard"]. Records of a group of New Yorkers headed for the California gold fields in 1849 show that they took along four "hickory shirts" apiece. Hickory cloth would later furnish the material for some "fatigue" pantaloons and shirts in the
American Civil War.
The word 'dungarees', to identify heavy cotton pants such as
overalls can be traced to a thick cotton country-made cloth, ''Dongari Kapar'', which was sold in the quarter contiguous to the Dongari Killa, the fort of what was then known as
Bombay (
''Hobson Johnson Dictionary''). The word entered English with just this meaning in 1696 (''
OED''). Dongri Fort was rebuilt in 1769 as Fort George, Bombay, where the first cotton mill was established in 1854. Dyed in indigo, the traditional cloth was used by Portuguese sailors and cut wide so that the legs could be swiftly rolled up when necessary. Thus, dungarees have a separate history.
Dry denim

Dry denim can be identified by its lack of a wash, or "fade". It typically starts out as the dark blue color pictured here.
'Dry denim', as opposed to
washed denim, is a denim
fabric that is not washed after being dyed during its production.
Most denim is washed after being crafted into an article of clothing in order to make it softer and to eliminate any shrinkage which could cause an item to not fit after the owner washes it. In addition to being washed, non-dry denim is sometimes artificially "distressed" to achieve a worn-in look.
Much of the appeal of dry denim lies in the fact that with time the fabric will fade in a manner similar to that which artificially distressed denim attempts to replicate. With dry denim, however, such fading is affected by the body of the person who wears the jeans and the activities of their daily life. This creates what many feel to be a more natural, unique look than pre-distressed denim.
To facilitate the natural distressing process, some wearers of dry denim will often abstain from washing their jeans for more than six months
[3], though it is not a necessity for fading.
Predominantly found in premium denim lines, dry denim represents a small niche in the overall market.
Selvage denim

thumb
'Selvage denim' (sometimes called 'selvedge denim') is a type of denim which forms a clean natural edge that does not unravel. It is commonly presented in the unwashed or raw state. Typically, the selvage edges will be located along the outseam of the pants, making it visible when cuffs are worn. Although selvage denim is not completely synonymous with unwashed denim, the presence of selvage typically implies that the denim used is a higher quality.
The word "
selvage" comes from the phrase "self-edge" and denotes
denim made on old-style shuttle looms. These looms weave fabric with one continuous cross thread (the
weft) that is passed back and forth all the way down the length of the bolt. As the weft loops back into the edge of the denim it creates this “self-edge” or Selvage. Selvage is desirable because it can’t fray like lower grade denims that have separate wefts which leave an open edge that must be stitched. Shuttle looming is a more time-consuming weaving process that produces denim of a tighter weave resulting in a heavier weight fabric that lasts.
Shuttle looms weave a more narrow piece of fabric, and thus a longer piece of fabric is required to make a pair of jeans (approximately 3 yards). To maximize yield, traditional jean makers use the fabric all the way to the selvage edge. When the cuff is turned up the two selvage edges, where the denim is sewn together, can be seen. The selvage edge is usually stiched with colored thread: green, white, brown, yellow, and red (red is the most common). Fabric mills used these colors to differentiate between fabrics.
Most selvage jeans today are dyed with synthetic indigo, but natural
indigo dye is available in smaller niche denim labels. Loop dying machines feed a rope of cotton yarn through vats of indigo dye and then back out. The dye is allowed to oxidize before the next dip. Multiple dips create a deep dark indigo blue.
In response to increased demand for jeans in the 1950's, American denim manufacturers replaced the old shuttle style looms with modern projectile looms. The new looms produced fabric faster and wider (60-inches or wider), yet lighter and less durable. Synthetic dyeing techniques along with post-dye treatments were introduced to control shrink and twist.
Raw selvage is material that has not been washed once undergoing the dying process. It especially desirable because the material will fade in the creases and folds of the jeans. This process is known as whiskering.

Notes
1. In 1789 George Washington toured a Beverly, Massachusetts, factory producing machine-woven cotton denim. (Massachusetts Foundation for the Humanities: Mass Moments).
2. Serge weave, with a distinctly-twilled diagonal rib, is now more usually associated with sturdy woollen textiles.
