Context: Textile Minister holds first meeting of the newly constituted Textile Advisory Group for Manmade Fibre (MMF).
About Man-made fibres (MMF):
- Man-made fibres (MMF) are fibres made by man.
- MMF can be organic or inorganic.
- Organic MMF can be made from natural materials like wood, or are made from synthetic polymers.
Classification of Man-made Fibres
- Synthetic fibres are synthesis from chemical processes.
- Examples of synthetic fibres are nylon, acrylic, polyester etc.
- These are semi-synthetic fibres that are made from the raw materials having long chain polymer structures.
- Modified and are partially degraded during the chemical processes.
- Made from cellulose polymers that are naturally occurring in cotton, wood, hemp, flax etc.
- Cellulose is first converted into a pure form of viscous mass and is then converted into fibres by extrusion through spinnerets.
- The first man-made regenerated fibres are rayon and acetate.
Advantages of MMF: High strength, Retains their original shape, Elastic, Soft, Low cost, Colours can be easily incorporated into man-made fibres, They are lightweight materials and easy manufacturing.
Disadvantages of MMF:
- Man-made fibres do not absorb moisture and traps heat in our body.
- Some man-made fibres cause skin allergies due to their dermatological actions.
- Man-made fibre fails to absorb the perspiration
