Question

Fill in the blanks with appropriate words.

(a) Synthetic fibres are also called __________ or __________ fibres.

(b) Synthetic fibres are synthesised from raw material called __________.

(c) Like synthetic fibres, plastic is also a __________.

Answer 1

Synthetic fibres:

1. Synthetic fibres are man-made fibres, and the majority of them are manufactured from petrochemicals, a byproduct of the processing of petroleum.
2. Fibers are the basis for all fabrics, and they come from man-made sources, animals sources and plant as well
3. They have formed either a tiny unit or a polymer that is constructed from numerous repeating monomeric building blocks.
4. Some examples include rayon, nylon, polyester, etc.
5. Cellulose polymers were used to create materials like rayon and acetate, two of the first man-made fibres to be developed.
6. In this case, plant cellulose was extracted and turned into fibres.
7. Only the polymers contained in natural gas and petroleum byproducts are used to make synthetic fibres.

Final answer:

1. Synthetic fibres are also referred to as artificial or manmade fibres.
2. Synthetic fibres are synthesized from a raw material called petrochemicals
3. Like synthetic fibres, plastic is also a polymer.
