Textile production workers use a range of machines and processes to produce fabrics, yarn and other textiles. Raw natural fibres, such as cotton and wool and synthetic fibres such as nylon and polyester, are combed, carded and drawn out into long strands, before being spun into yarn and wound onto special reels, called bobbins. Depending on the type of material or product, the yarn is then ready for weaving or knitting. In some cases, these processes can be performed manually by skilled craftspeople, however, most commercial manufacturers will use specialised machinery. The final steps in textiles production are dyeing and finishing, where fabrics and other textiles are coloured, have designs printed on them and are treated to keep them from shrinking, fading, wrinkling and/or soiling easily.
