Question

Choose which of the following is the typical behaviour of plastic.

  1. Electrical conductors
  2. Heat conductors
  3. Biodegradable
  4. Non-biodegradable

hintHint:

They can not be digested by microorganisms.

    ____ is the synthetic fiber used to make parachutes.

    The correct option is c)Nylon.
    Nylon threads are very strong and can withstand high loads. As such, it is used to make parachutes and ropes for climbing. Nylon fibers are strong, elastic and shiny. It is easy to wash, dries quickly even after washing, and does not lose its shape. These properties make it ideal for making parachutes and raincoats.

    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.
