Answer:
1.Synthetic Fibres:They r the fibres made artificial by humans using various chemicals
2 Thermoplastics:They r substances which wen are heated tends to form plastic.
3.Thermosetting plastics:It is a plastic which is irreversibly hardened by curing from a soft solid or viscous liquid prepolymer or resin.
4.Biodegradabe:They r the substances which decompose due to the result of various bacteria or other living creatures.
5.Non Biodegradable:They r substances which do not decompose or take a very long tym to decompose .Hence cause pollution
Answer:
1)synthetic fiber is any of various man-made textile fibers including usually those made from natural materials (such as rayon and acetate from cellulose or regenerated protein fibers from zein or casein) as well as fully synthetic fibers (such as nylon or acrylic fibers) — compare polymer.
2)Thermoplastics are defined as polymers that can be melted and recast almost indefinitely. They are molten when heated and harden upon cooling. When frozen, however, a thermoplastic becomes glass-like and subject to fracture.
3)A thermosetting polymer, resin, or plastic, often called a thermoset, is a polymer that is irreversibly hardened by curing from a soft solid or viscous liquid prepolymer or resin. Curing is induced by heat or suitable radiation and may be promoted by high pressure, or mixing with a catalyst.
4)“Biodegradable” refers to the ability of things to get disintegrated (decomposed) by the action of micro-organisms such as bacteria or fungi biological (with or without oxygen) while getting assimilated into the natural environment.
5)Definition of nonbiodegradable. : not capable of being broken down by the action of living organisms : not biodegradable nonbiodegradable packaging.
