The following sub-topics will be covered under this topic:
- Classification of Textile Fibres
- Properties of Textile Fibres
Fibres are classified into two main groups:
– Wool fibre
These are fibres that are not made purely from natural raw materials.
They are classified into two groups:
They are made from natural fibres treated with chemical substances.
- Viscose Rayon
- Acetate Rayon
Viscose rayon is made from cotton linters and chemicals.
– Acetate Rayon
– Acetate rayon is made from wood pulp and chemicals.
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 are made from benzene (from coal), oxygen and nitrogen (from air) and hydrogen (from water).
Polyamide under the microscope
Polyester fibres are derived from petroleum.
This is produced from acrylonitrile, a liquid produced from petroleum or natural gas.
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.
