A modern "shuttle-less" loom (which uses a very small carrier instead of the traditional shuttle to weave the weft threads between the warp threads) may produce as much as 3,279 yards (3,000 meters) of cloth 3.28 or 4.37 yards (three or four meters) wide in a single week. As much as 1,093 yards (1,000 meters) of cloth may be rolled into a single huge bolt.
At this point the denim is ready for finishing, a term referring to a variety of treatments applied to cloth after it is woven. With denim, finishing is usually fairly simple. The cloth is brushed to remove loose threads and lint, and the denim is usually skewed in a way that will prevent it from twisting when it is made into clothing. The denim may then be sanforized, or preshrunk. Preshrunk denim should shrink no more than three percent after three washings.
After being crafted into an article of clothing, most denim is washed to make it softer and to reduce or eliminate 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 produce a worn look.
Much of the appeal of factory distressed denim is that it looks similar to dry denim that has, with time, faded. With dry denim, however, such fading is affected by the body of the person who wears the jeans and the activities of his/her daily life. This creates what many enthusiasts feel to be a more natural, unique look than 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, 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. In both cases the yarn will undergo a repetitive sequence of dipping and oxidization, the more dipps, the stronger the indigo shade.
Making the blue jeans
Once the desired design is selected, patterns from the design are cut from heavy paper or cardboard. Up to 80 different sizes are possible from one pattern. The pieces of denim are then cut with high speed cutting machines from stacks 100 layers thick. Excluding rivets, buttons, and zippers, a pair of blue jeans contains about ten different pieces, from the pockets to the leg panels to the waistband and belt loops.
The pieces of denim are ready to be sewn at this point. Sewing is done in an assembly line fashion, with rows of industrial human-operated sewing machines. Each sewer is assigned a specific function, such as making only back pockets. First, the various pockets and belt loops are assembled. Next, one sewer attaches the pockets to the leg seams, another then sews the leg seams together, and still another attaches the waist-band. Once the waist band is secure, the belt loops may be stitched on and the buttons attached. If the jeans include a zipper, it is then sewn into place, and the pants are hemmed. Finally, the rivets are placed in the appropriate places and the maker's label is sewn on last.
Some jeans are prewashed and/or stone-washed to alter the appearance or texture of the finished jeans. Prewashing involves washing the jeans in industrial detergent for a short time to soften the denim. Stone-washing also means washing the jeans, but pumice is added to the load, resulting in a faded appearance. Small stones (less than one inch [one centimeter] in diameter) produce an even abrasion, while large stones (about four inches [10 centimeters] in diameter) highlight the seams and pockets and produce a more uneven appearance.
