Question

Fibres can be either natural or man-made. Based on the source of the fibre, which of the following sets of fibres have different origin? *

Answer 1

Answer:

Synthetic fibres are manufactured using plant materials and minerals: viscose comes from pine trees or petrochemicals, while acrylic, nylon and polyester come from oil and coal. Viscose fibre is obtained from the cellulose; versatility allows imitating materials such as cotton or silk.

Textiles are made from many materials, with four main sources: animal (wool, silk), plant (cotton, flax, jute, bamboo), mineral (asbestos, glass fibre), and synthetic (nylon, polyester, acrylic, rayon). The first three are natural.Plant fibres are obtainedfrom plants. e.g., jute. Animal fibres are obtained from animals, e.g., silk and wool. Fibres which are made by the human are Man-made or Synthetic Fibres, e.g., Rayon.
