Natrual ibres are used in textiles. These can be from animals or plants.
The main animal based fibres are wool and silk and the main Plant based fibres are: Cotton, linen, jute, hemp,
Synthetic Fibres are also used. These are Man made fibres from oil based products.
such as Acrylic and Polyamide
Micro fibres are fine synthetic fibres such as Polyester and nylon.
Regenerated fabrics are made from natrual fibres which have had their structure chemicaly altered by man. These are made from diffrent combinations of chemicals and cellulose water and some example of this are viscose and acetate.
Yarns are fibres that have been twisted into long lengths and are wounded onto spools or cones. They are made by spinning and twisting fibres together using one of two methods. The worsted spinning system produces a smooth yarn and the woollen spinning system produces a hairy yarn.
The yarn is then spun in an anticlockwise direction (s twist) or a clockwise direction (z twist). When making more complex yarns both Z and S twists are combined in equal amounts to prevent distortion. There are different types of yarn which are:
Spun yarn, Filament yarns, Multi filament yarns, Monofilament yarns and assembled yarns and folded yarns.
