As discussed previously, the various finishing processes used for wool fabrics can be placed in two groups: wet finishing and dry finishing. The wet finishing processes are not always carried out in the same order; but depend upon the type of wool fabric being processed and the nature of the required finish.
The small, sticky seeds must be separated from the wool in order to process the cotton for spinning and weaving. De-seeded cotton is cleaned, carded (fibers aligned), spun, and woven into a fabric that is also referred to as cotton. Cotton is easily spun into yarn as the cotton fibers flatten, twist, and naturally interlock for spinning.
In the stone groundwood process, de-barked logs are forced against rotating stone grind-ing wheels that are constantly washed by a stream of water.

Principle: jet dyeing is a process that can be used for batch dyeing operations such as dyeing, bleaching, washing and rinsing. In this process, dyeing is accomplished in a closed tubular system, basically composed of an impeller pump and a shallow dye bath. The fabric to be dyed is loosely collapsed in a form of a rope, and tied into a loop.
Ginning: includes resource use and emissions associated with the ginning process.
The rotary-knife roller gin has a considerably higher ginning rate than the mccarthy gin [218 kg (480 lb) versus 18 kg (40 lb) of lint per hour on a 1-m (40-in) wide stand], though the rotary knife gin still processes cotton at only about one-fifth the rate of a saw gin with an equivalent width.

With the sirospun™ process, a special spin-twisted yarn can be produced directly on the ring-spinning machine. In this process, two rovings are led in parallel through the drafting system, separated by two specially developed condensers, and drafted separately.
