Characteristics of synthetic fibres

1)Synthetic fibres are very strong

2)Synthetic fibres are more durable: They have high resistance to wear and tear. Due to this, clothes made of synthetic fibres are very durable.

Natural fibres have low abrasion due to which the clothes made of natural fibres are not much durable.

3)Synthetic fibres absorb very little water: Clothes made of Synthetic fibres dry very quickly.

Clothes made from natural fibres do not dry quickly.

4)Synthetic fibres are wrinkle resistant: The clothes made of Synthetic fibres do not get crumpled easily during washing or wear.

Natural fibres get crumpled easily during washing and wear.

5)Synthetic fibres are light weight

6)Synthetic fibres are extremely fine: The fabric made from from synthetic fibres have a very smooth texture whereas natural fibres are not so fine.

7)Synthetic fibres are not attacked by moths

8)Synthetic fibres do not shrink

9)Synthetic fibres are less expensive and readily available.

Disadvantage of synthetic fibres

1)They melt on heating: If a person is wearing clothes made of synthetic fibres and his clothes catch fire accidentally,then the Synthetic fibres of clothes melt and stick to the body of the person causing severe burns.

We should not wear synthetic clothes while working in the kitchen or laboratory.

The natural fibres do not melt on heating. So it is safe to wear clothes made of natural fibres while working in the kitchen or laboratory.

2)The clothes made of synthetic fibres are not suitable for wearing during hot summer weather: They are extremely fine so the clothes made of synthetic fibres do not have sufficient pores for the sweat to come out,evaporate and cool our body. Due to this, clothes made of synthetic fibres make us feel hot and uncomfortable. during summer.

Clothes made from natural fibres are more comfortable during summers. Because the large pores of cotton clothes allow the body sweat to come out through them, evaporate and make us feel cool and comfortable.
