Answer:There are some fibres that are prepared by man by using chemicals. These are called synthetic fibres. These are made of small units that join together to form long chains. Examples of synthetic fibres are rayon, nylon, polyester, acrylic, etc.
Explanation:
Plastics are not corroded even if they come in contact with strong chemicals. This is
because of their non-reactive nature with most materials. For example, the cleansing
chemicals that we use at home are stored in plastic bottles, instead of metal containers.
Explanation:

2 when plastic born it produce carbon mono oxide and carbon dioxide and other various gases that pollute the atmosphere and nature so it was non corrosive in nature
