Question

Terrycot fibre is made using:
A. Wood pulp
B. Esters
C. Acrylic
D. Paper pulp

Answer 1

Hint: Try to recall that the term ‘terrycot’ is made up by using two different types of fabrics, one of which terylene. Now, by using this you can easily find the correct option from the given options.

Complete step by step answer:
- It is known that terrycot is a form of fabric which is made by mixing two different types of fabrics namely, terylene and cotton.
- In terrycot, generally the cotton and terylene are mixed in the ratio of 65:35.
- Terylene is a synthetic polyester fibre.
- Polyester combines well with natural fibres, such as cotton so they are used in making clothes.
- The structure of terylene is:

Here, we can see the two ester functional groups that are present in the monomer (repeating unit) of terylene, thus we call it a polyester fibre.
So, the correct answer is “Option B”.

Additional Information:
- Terylene is produced by polymerizing ethylene glycol and terephthalic acid which is obtained from petroleum.
- Terylene is polyester, so it reduces shrinking and wrinkling, and makes the fabric more colorfast.
- It can be made from recycled plastic bottles, so it offers an element of sustainability.

Note: It should be remembered to you that synthetic fibres are those fibres which are man-made i.e. made by the human beings. The common synthetic fibres are rayon, nylon, acrylic, olefin, etc. Also, you should remember that fibres which are made from wood pulp are known as regenerated fibres and rayon is the best example of regenerated fibres. We will not consider the composition of cottons since the proportion is lesser than terylene.
