Textile industry

Source: Wikipedia, the free encyclopedia.

An old textile factory ("Cvernovka") in Bratislava, Slovakia (1901–2004).
Textile factory (Germany, c. 1975).

The textile industry is primarily concerned with the design, production and distribution of textiles: yarn, cloth and clothing. The raw material may be natural, or synthetic using products of the chemical industry.

Cotton is the world's most important natural fibre. In the year 2007, the global yield was 25 million tons from 35 million hectares cultivated in more than 50 countries.[1] There are five stages of cotton manufacturing:[2]

  • Cultivating and harvesting
  • Preparatory processes
  • Spinning — giving yarn
  • Weaving — giving fabrics[a]
  • Finishing — giving textiles

In the textile industry, textile engineering is an area of engineering that involves the design, production, and distribution of textile products through processes including cultivation, harvesting, spinning, weaving, and finishing of raw materials, encompassing both natural and synthetic fibers.[3]

Synthetic fibres

Artificial fibres can be made by extruding a polymer, through a spinneret (polymers) into a medium where it hardens. Wet spinning (rayon) uses a coagulating medium. In dry spinning (acetate and triacetate), the polymer is contained in a solvent that evaporates in the heated exit chamber. In melt spinning (nylons and polyesters) the extruded polymer is cooled in gas or air and then sets.[4]
Some examples of synthetic fibers are polyester, rayon, acrylic fibers and microfibers. All these fibres will be of great length, often kilometres long. Synthetic fibers are more durable than most natural fibers and will readily pick-up different dyes .

Artificial fibres can be processed as long fibres or batched and cut so they can be processed like natural fibre.

Natural fibres

Sheep, goats, rabbits, silkworms, and other animals, as well as minerals like asbestos, are sources of natural fibers (cotton, flax, sisal). These vegetable fibers can originate from the seed (cotton), the stem (bast fibres: flax, hemp, jute), or the leaf (sisal). All of these sources require a number of steps, each of which has a distinct name, before a clean, even staple is produced. All of these fibers, with the exception of silk, are short, only a few centimeters long, and have a rough surface that allows them to adhere to other like staple fibers.
