Question

___________ are used to manufacture synthetic fiber​

Answer 1

Explanation:

Synthetic fibers are made from synthesized polymers of small molecules. The compounds that are used to make these fibers 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.

Answer 2

Synthetic fibres are manufactured using plant materials and minerals: viscose comes from pine trees or petrochemicals, while acrylic, nylon and polyester come from oil and coal. Viscose fibre is obtained from the cellulose; versatility allows imitating materials such as cotton or silk.
