Important notes of synthetic fibres and plastic class 8
Dear Student,
Synthetic fibres:-
Synthetic fibres are made from synthesised polymers or small molecules. The compounds that are used to make these fibres come from raw materials such as petroleum based chemicals or petrochemicals. These materials are polymerized into a long, linear chemical that bond two adjacent carbon atoms. Differing chemical compounds will be used to produce different types of fibres. Although there are several different synthetic fibres, they generally have the same common properties. Generally, they are known for being:
->Heat-sensitive
->Resistant to most chemicals
->Resistant to insects, fungi and rot.
->Low moisture absorbency
->Electrostatic
->Flame resistant
->Density or specific gravity
->May pill easily
->Low melting temperature
->Often less expensive than natural fibres.
->Easy to wash and maintain.
Plastics:-
A plastic material is a wide range of synthetic or semi-synthetic organic solids that are moldable.They are usually synthetic, derived from petrochemicals.Due to their relatively low cost, ease of manufacture e.t.c plastics are used in large range of products, from paper clips to spaceships.The word plastic is derived from the greek word 'plastikos' which means "capable of being shaped or moulded".
Regards,
