Man Made Fibre

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:

• Synthetic fibres are synthesis from chemical processes.
• Examples of synthetic fibres are nylon, acrylic, polyester etc.

Regenerated Fibres:

• 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
