Question

Give two reasons for using synthetic fibres over natural

Answer 1

Strong: Synthetic fibres are strong so they can take up heavy things easily.


Retain their original shape: Synthetic fibres retain their original shape so it's easy to wash and wear.


Elastic: Can easily be stretched out.


Soft: Synthetic fibres are generally soft so they are used in clothing materials.


Colour: Varieties of colours are available as they are manufactured.


Cost: Clothes made by synthetic fibres are generally cheaper than those made by natural fibres.


Specific qualities of fibres can be produced deliberately and quickly in accordance with the demand. 


The filaments can be produced as fine or as coarse as required, staple lengths can be cut exactly to order. Fibres can be produced with a high degree of lustre, with reduced or completely dull lustre, as required.
 
Unlike natural fibres, the final product of manmade fibres does not require cleaning. 


Most of the fibres are pure white or colourless when produced, but if necessary, colour can be incorporated during the production of the manmade fibres. 


The growth and utility of manmade fibres are mainly influenced by its positive qualities, viz. wrinkle resistance, crease recovery, easy care properties, etc. Manmade fibre fabrics bring out substantial saving on laundry costs; unlike cotton, it can be washed in a basin in the evening, hung up to dry and be worn without ironing the following morning. 


The light weight characteristic of manmade fibre fabrics gives more mobility because of less weight and quantity—a tourist can take along with, him a few clothes. Hence, these fibres are referred to as Easy-Care fibre fabrics.


Most of the synthetic fibres possess high resistance to moth, mildew, insects, mould, which simplify the storage problems, the economy of little loss from these causes.

Answer 2

Synthetic fibers are more durable than most natural fibers and will readily pick-up different dyes. In addition, many synthetic fibers offer consumer-friendly functions such as stretching, waterproofing and stain resistance. Sunlight, moisture, and oils from human skin cause all fibers to break down and wear away.
