Answer (1)
A fibre also known as artificial silk?
The fibre known as artificial silk is called Rayon. Rayon is a man-made fibre derived from cellulose, which was first developed in the late 19th century as a substitute for silk. It has a silky appearance and is soft to the touch, making it popular in clothing and textiles.
A synthetic fibre used for making swimwear?
Nylon is a synthetic fibre commonly used for making swimwear. It is known for its strength, elasticity, and resistance to damage from water and chlorine, making it ideal for use in swimming suits and other water-related garments.
Lycra is the other name of?
Lycra is the other name for Spandex. Spandex is a synthetic fibre known for its exceptional elasticity. It is often used in clothing that requires a snug fit, such as sportswear, underwear, and swimwear.
Plastics that have heavy cross-linking?
Plastics with heavy cross-linking are known as thermosetting plastics. These plastics are made up of polymer chains that are heavily cross-linked, which gives them high structural integrity and makes them heat resistant. Once set, they do not melt but can char or burn, making them suitable for high-temperature applications. Examples include Bakelite and epoxy resins.
Substances that cannot be decomposed?
Substances that cannot be decomposed are referred to as non-biodegradable substances. These materials do not break down naturally in the environment through the action of living organisms, and they can persist for long periods, often leading to environmental issues. Common examples of non-biodegradable substances include plastics, glass, and metals.
