TEXTILE FIBRES The following sub-topics will be covered under this topic: Classification of Textile Fibres Properties of Textile Fibres Fibres Fibres are classified into two main groups: - Natural - Man-made - Wool fibre Natural Fibres Animal Plant Mineral Animal Fibres Wool Silk Plant Fibres Cotton Linen Man-made Fibres These are fibres that are not made purely from natural raw materials. They are classified into two groups: Regenerated Synthetic Regenerated Fibres They are made from natural fibres treated with chemical substances. They include: Viscose Rayon Acetate Rayon Viscose Rayon Viscose rayon is made from cotton linters and chemicals. - Spinneret - Acetate Rayon - Acetate rayon is made from wood pulp and chemicals. Synthetic Fibres Synthetic fibres are made from chemicals. These chemicals are derived from coal, oil or petroleum products. The fibres are made through a process known as polymerisation where polymers are made by the combination of small molecules. They include: Polyamide Polyester Polyacrylics Polyamide They are made from benzene (from coal), oxygen and nitrogen (from air) and hydrogen (from water). Polyamide under the microscope Polyester Polyester fibres are derived from petroleum. Polyacrylics This is produced from acrylonitrile, a liquid produced from petroleum or natural gas. Elastomerics They are elastic and rubber like substances made from polyunethane. - Properties of Textile Fibres - Properties of Cotton Cotton is produced from the cotton plant. It is one of the most popular natural fibres used to make personal and household articles. See also BODY MEASUREMENTSDISEASES Wrist measurement SYNTHETIC FIBRES WOOL cotton
