$\bold { \red{EXPLANATION: }}$

WHAT ARE NATURAL FIBRES

Fibres obtained from natural sources like plants and animals are called natural fibres.

Examples: Cotton, Silk, Wool, Jute and Hemp.

MERITS:

• Comfortable: Clothes made by natural fibres are more comfortable than those made of synthetic fibres.
• Environment: Producing materials from natural fibres are less harmful to our environment.
• Non allergic to skin
• They are resistant to fire.
• Natural fibers on burning do not produce poisonous gases.
• Natural fibers are easily affordable.
• These fibers absorb sweat and water and hence such clothes are comfortable for summer months.

DEMERITS

• Expensive: Materials produced by natural fibres are generally expensive as synthetic fibres can be made easily by manufacturing.
• Shrink: Natural fibres might shrink due to aggressive washing.
• Unlike manmade fibres, natural fibres are not available in high tenacity (HT) and medium tenacity (MT).
• Natural fibres do not possess a high degree of resiliency as compared to manmade fibres, hence the fabrics made out of them do get wrinkles from ‘baggy knees’, possess less crease recovery.
• Production of natural fibres cannot be completely controllable. Therefore, from year to year quantities of specific qualities vary and this tends to cause price fluctuations according to variations in demand which cannot be foreseen until the fibres have been produced.
