Question

Which of the folllowing statements is true?

• A. Nylon is processed by the chemical treatment of wood pulp.
• B. Acrylic is similar to silk in texture and feel.
• C. The water-absorbing capacity of synthetic fibres is more than the natural fibres.
• D. Natural fibres burn slowly as compared to synthetic fibres.

Answer 1

The correct option is D Natural fibres burn slowly as compared to synthetic fibres.

$\bullet$ Nylon is the first fully synthetic fibre. It is made using coal, water and air. Rayon is the fibre that is obtained by the chemical treatment of wood pulp.

$\bullet$ Acrylic is called artificial wool and is used to make winter wear like sweaters. Both acrylic and wool are warm and soft. Rayon is called the artificial silk and similar to silk in texture and feel. Both rayon and silk are smooth and shiny.

$\bullet$ Natural fibres are generally water-absorbent while synthetic fibres are generally water-resistant. Therefore, the water-absorbing capacity of synthetic fibres is less than that the natural fibres.

$\bullet$ Synthetic fibres catch fire easily. They melt and stick to the body of the person wearing clothes made up of them. Natural fibres burn slowly and do not melt.
