Some cloths are woven (see step 5 below) and then dyed, but denim is usually dyed with chemically synthesized indigo before being woven. Large balls of yarn, called ball warps, are dipped in the indigo mixture several times so that the dye covers the yarn in layers. (These many layers of indigo dye explain why blue jeans fade slightly with each washing.) Although the exact chemicals used in such dyeing procedures remain trade secrets, it is known that a small amount of sulfur is often used to stabilize the top or bottom layers of indigo dye. The dyed yarn is then slashed; that is, it is coated with sizing (any one of a variety of starchy substances) to make the threads stronger and stiffer. Once this operation is complete, the yarn threads are ready to woven with undyed filling yarn threads.

The word "selvage" comes from the phrase "self-edge", the natural edge of a roll of fabric. In this case, 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 the edge 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 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.

Weaving the yarn
The yarn is then woven on large mechanical looms. Denim is not 100 percent blue, as the blue dyed threads forming the warp(long, vertical threads) are combined with white threads forming the weft (shorter, horizontal threads). Because denim is woven with the blue threads packed closer together than the white threads and with the blue threads covering three out of four white threads, the blue threads dominate. (By examining a piece of denim closely one can detect the steep diagonal pattern that results from this process, which is known as a three-by-one right-hand twill weave.) Although mechanized looms make use of the same basic weaving procedure as a simple hand loom, they are much larger and faster. 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.
