what type of fibre is polycot??​

Answer 1

Answer:

1. Polymer is made up of monomers. Monomers are the smallest unit of fibre.
2. Cellulose is the main raw material used to make Rayon.
3. Advantages of nylon

• It is lightweight and elastic that is why it is used to make bristles of tooth brush.
• It is wrinkle resistant.
• 4. Fabrics are sold by names like polycot, polywool, terrycot, etc. As the name suggests, these are made by mixing two types of fibres. Polycot is a mixture of polyester and cotton. Polywool is a mixture of polyester and wool.

Answer 2

Answer:

1) Many common classes of polymers are composed of hydrocarbons, compounds of carbon and hydrogen. These polymers are specifically made of carbon atoms bonded together, one to the next, into long chains that are called the backbone of the polymer.

2) Whether it is wood pulp or cotton linters, the basic raw material for making rayon must be processed in order to extract and purify the cellulose. The resulting sheets of white, purified cellulose are then treated to form regenerated cellulose filaments.

3) Nylon is a popular synthetic material that has many advantages, including being resistant to heat, and very few disadvantages, including easily losing its shape. It is used in many items, such as clothing, carpet, storage containers, and more. Nylon has lengthy durability.

4) Polycot is a mixture of polyester and cotton. Polywool is a mixture of polyester and wool.
