Question

Polycot is a mixture of:
A. cotton and nylon
B. polyester and nylon
C. polyester and cotton
D. wool and polyester

Answer 1

Hint: Fibers are the basic unit of all textiles. Natural fibers are mixed with polyester to make blended fabrics. Blended fabrics are fabrics made by mixing or blending two types of fibers. Polyester is blended with other fibers like cotton, cotton, rayon etc.

Complete step by step answer:
Natural fibers are the fibers which are made from natural sources. E.g. cotton, silk, wool etc.
Synthetic fibers are the fibers which are man-made. E.g. rayon, nylon, acrylic, etc. They are small units of chemicals joined together in the form of chains. The chain formed is called a polymer. Polymer means made of many units joined together. The process of joining together monomers to form a polymer is called a polymerization. Each synthetic fiber has its own properties.
Nylon is a thermoplastic which melts on heating. They are made from petrochemicals. They are polyamides with recurring amide groups. They contain carbon, oxygen, nitrogen and hydrogen elements. They are strong, light weight, moth resistant, durable, long lasting, elastic, stretchable, washable and lustrous. They have low absorbency.
Polyester is a category of polymers which contain the ester functional group in their main chain. They are generally colorless, transparent, smooth, strong, and resistant to stretching and shrinking. Polyester is blended with cotton to form polycot to resist wrinkles, stains and shape. Polywool is the mixture of polyester and wool. They have properties of both natural fibers and polyester.


So, the correct answer is Option C .

Note:
Polyester is resistant to most chemicals, crisp and resilient when wet or dry, wrinkle resistant, easily washed and abrasion resistant. This combination of polyester and cotton is easier to wear in summer due to its cotton content with all the advantages of synthetic fiber. They can be used to make pants, shirts, suits and other dresses.
