Poly Ethylene Terephthalate

PET is a abbreviation of the synthetic polymer called Poly Ethylene Terephthalate.

PET can be made into a fibre or plastic.

1)PET as a plastic is very lightweight.

2)It is naturally colourless with high transparency.

3)PET is strong and impact-resistant.

4)It is used for making bottles,jars and utensils.

5)It is also used for making thin films and many other useful products.


Acrylic is a synthetic fibre.It is made from a chemical called acrylonitrile  by the process of polymerisation.


1)It is lightweight,soft and warm with a wool like feel.

2)It retains its shape,resists shrinkage and wrinkles.

3)It can be dyed very well.

4)Acrylic fibres are strong and durable.

5)Acrylic absorb very little water so it has quick dry quality.

6)Acrylic fibres are resistant to moths and most chemicals.

Acrylic fibres is often used as a substitute for wool.The wool obtained from natural sources is quite expensive.Acrylic offers a less expensive alternative to natural wool.So the clothes made from acrylic are relatively cheaper but more durable than those made from natural wool.
