Answer 1

Answer:

Nylon fibers are exceptionally strong and elastic and stronger than polyester fibers. The fibers have excellent toughness, abrasion resistance, and are easy to wash, and to dye in a wide range of colors. The filament yarns provide a smooth, soft, and lightweight fabric of high resilience.

Nylon is used in the garment and home furnishing industry. However, due to its higher price and lesser wrinkle resistance, it has been replaced by polyester in many garment products. Yet, it remains an important fiber for more demanding applications, including tire cords, ropes, seat belts, hoses, conveyer belts, carpets, parachutes, racket strings, sleeping bags, tents, and various civil engineering materials

Answer 2

The raw material which makes nylon thread is actually a polyamide. There is polymerization of the substance resulting in the formation of a long chain.
