Question

Ester is used in repeating units in the making of polyester. Choose true or false.

  1. True
  2. False

hintHint:

The single unit of the polymer which repeats again and again is known as a monomer. polyester is a homopolymer.

The correct answer is 'True'.


    • Polyester is a man-made or synthetic fiber made up of repeating units of chemicals called esters.
    • Esters are sweet-smelling compounds composed primarily of carbon, hydrogen, and oxygen.
    • The most commonly used polyester formula is: As an ester, it is made from the acid benzene-1,4-dicarboxylic acid (terephthalic acid) and the alcohol ethane-1,2-diol.
    • It is better known by the mundane name of polyethylene terephthalate (PET).

    The correct option is a)1931.
    Nylon, a synthetic plastic material composed of polyamides of high molecular weight, usually but not always manufactured as fibers. In the 1930s he founded the E.I. du Pont de Nemours & Company.
    Nylons are a family of materials called polyamides, made by reacting carbon-based chemicals found in coal and petroleum in a heated, high-pressure environment. This chemical reaction, known as condensation polymerization, forms large polymers in the form of nylon films.

    Synthetic fibers do not absorb much

    The correct option is c)Water.
    Synthetic fibers absorb less water than natural fibers because there are no voids between each fiber. Because water does not penetrate the individual fibers of this fabric, it dries quickly. Hydrophilic fibers readily absorb water without causing discomfort to the wearer, whereas hydrophobic fibers are where the fibers do not absorb water.

    In which season is wearing rayon clothes comfortable?

    The correct option is d)Summer.

    • Viscose is very similar to cotton and linen. It does not trap body heat and absorbs water easily, keeping you cool and comfortable in tropical conditions.
    • Therefore, it is a particularly suitable fabric for summer.
    • Rayon has very fine fibers, so it is more breathable than other fabrics and is light enough to not stick to the body even in hot weather.
    • Due to its comfortable and cool feel, viscose is a particularly suitable fabric for sportswear and summer dresses.
