Question

Write about any two synthetic fibres .
( At least 10 line )​

Answer 1

Answer:

Synthetic fibres are used for making clothes and many other useful things. They may be entirely synthetic or semisynthetic. Semisynthetic fibres, like rayons, are made by using natural polymers as the starting material. Purely synthetic fibres, on the other hand, are made from chemicals. Polyesters, nylons and acrylics are purely synthetic fibres.

Explanation:

Rayons:

These are the most widely used semisynthetic fibres. They are derived from cellulose and are available in three different varieties— viscose, cuprammonium (or cupro) and acetate rayons.

Viscose Rayon:

Cellulose (say, cotton) is dissolved in a mixture of sodium hydroxide (NaOH) and carbon disulphide (CS2, a solvent). A viscous liquid (i.e., a liquid which cannot flow freely) called viscose is obtained. The viscose is then forced through spinnerets (which have small holes) into an acid bath, and filaments of viscose rayon are obtained.

Answer 2

Explanation:

Synthetic fibers are used for making clothes and many more things. Rayon, Nilon, sulphur are the examples of synthetic fibers. These fibers are man made.They are not natural. These synthetic fibers are used in making fine clothes. Like - making jute boots, and rainy clothes , rainy coats, and many more useful items. These are made from chemicals. The can harm the environment and ourselfs also.
