Traditionally, jeans are dyed to a blue color using an indigo dye. Approximately 20 thousand tons of indigo are produced annually for this purpose, though only a few grams of the dye are required for each pair of these trousers. Some other colors that can be achieved are pink, yellow, black, and white.

Pre-shrinking of jeans
Young people wearing a variety of jean styles, including carpenter jeans, bootcut jeans, drainpipe jeans and lowrise jeans. (Rome, 2008)
Levi Strauss first marketed preshrunk jeans, which did not shrink further after purchase, allowing the consumer to buy his or her correct size, in 1963.
Used look created by sandblasting
Consumers wanting jeans that appear worn can buy jeans that have been specially treated. To give the fabrics the worn look, sandblasting is often used. Sandblasting has the risk of causing silicosis to the workers, and in Turkey, more than 5,000 workers in the textile industry have been stricken with this disease, and 46 people are known to have died. Some companies have announced they are banning the use of sandblasting.
A typical pair of blue jeans consumes 919 gallons of water during its life cycle (this includes the water to irrigate the cotton crop, manufacture the jeans, and the numerous washes by the consumer). Because cotton is the world's biggest nonfood crop, and water shortages are a growing global trend, some jean companies are looking into ways to reduce the amount of water needed in their production of jeans—from field to factory.
Care and wear
To facilitate the natural distressing process, some wearers of dry denim will often abstain from washing their jeans for more than six months, though it is not a necessity for fading.
All Fabric has a selvedge (a words derived from the joining of "self" & "edge"), this is the natural edge of the cloth and contrary to some sources does not unravel or fray.
"Selvage denim" refers to a unique closed selvage (derived from the Latin Salvare, meaning "to secure, to make safe") that is created using one continuous cross yarn (the wefta) that is passed back and forth through the vertical warp beams. This is traditionally finished with a contrast weft, most commonly red which is why sometimes this type of denim is referred to as "Red Selvage". This process is only possible using a shuttle loom
Shuttle looms weave a narrower 30 inch fabric, which is on average half the width of the more modern shuttleless sulzer looms (invented in 1927 by the Sulzer brothers) and thus a longer piece of fabric is required to make a pair of jeans (approximately 3 yards). To maximize yield, jean where traditionally made with a straight outseam that utalised the full width of the fabric including this edge. This became not only desirable but since the production of wider width denim, a mark of premium quality as when worn with a turn up the two selvages where visable rather than a unatractive overlocked edge.
Originally Indigo was produced using dye from plan indegofera tinctoria but most denim today is dyed with synthetic. indigo In both cases the yarn will undergo a repetitive sequence of dipping and oxidization, the more dipps, the stronger the indigo shade.Rope dye is considered the best yarn dying method as it eliminated shading across the fabric width, thou the alternative slasher process is cheaper as only one beaming process is needed (in rope dying, beaing is done twice). Fades caused by prolonged periods of wear, without washing, have become the main allure for raw denim. The fading patterns are a way of personalizing the garment for each customer. These fades are categorized by certain namesWhiskers – Faded streaks that surround the crotch area of the denim. Combs – Also known, as “honey combs” are the streaks of faded lines that are found behind the knee. Stacks – Produced by having the inseam of the denim hemmed a few inches longer than actual leg length. The extra fabric stacks on top of the shoe causing a fade to form around the ankle to calf area of the denim. Train Tracks – appears on the outseams of the denim. This fade showcases the selvedge by forming two sets of fades that resemble train tracks. Originally Indigo was produced using dye from plant tinctoria but most denim today is dyed with synthetic.

Despite most jeans being “pre-shrunk”, they are still sensitive to slightly further shrinking and loss of coloring from being washed. The Levi Strauss company recommends avoiding washing jeans as much as possible. Carl Chiara, Levi Strauss director of brand and special projects, has a credo: The less you wash your jeans, the better your jeans become. These and other suggestions to avoid washing jeans where possible have encountered criticism. Cory Warren, editor of LS&Co. Unzipped, clarifies in a response to such a criticism.
