7. What is artificial silk?

Answer 1

Answer:

1.Wallace carothers

2.Wallace Hume carothers

3.C12H22N2O2)n

4.Nylon is made when the appropriate monomers (the chemical building blocks which make up polymers) are combined to form a long chain via a condensation polymerisation reaction. The monomers for nylon 6-6 are adipic acid and hexamethylene 

5.Clothing – Shirts, Foundation garments, lingerie, raincoats, underwear, swimwear and cycle wear.

Industrial uses – Conveyer and seat belts, parachutes, airbags, nets and ropes, tarpaulins, thread, and tents.

It is used to make a fishnet.

6.Nylon fibre is used in making ropes for rock climbing and parachutes because it is a very strong fibre

7.Artificial silk or art silk is any synthetic fiber which resembles silk, but typically costs less to produce. Frequently, "artificial silk" is just a synonym for rayon. When made out of bamboo viscose it is also sometimes called bamboo silk.
