Question

Acrylic, a man made fibre is a good substitute for a natural fibre. Which is this natural Fibre?
A) Wool
B) Silk
C) Cotton
D) Jute

Answer 1

Hint: Fibres are long, thin, and flexible thread-like structures. These may be spun into yarns, which can then be used to make fabrics. Fibres are divided into two categories based on their origin: natural and synthetic. Natural fibres are those that are derived from plants, animals, or minerals. Cotton, silk, and wool are among examples. Synthetic fibres are man-made polymers that are used to create fabrics. When multiple tiny components are chemically bonded together, polymers are formed.

Complete answer:
Let us analyze the given correct:
Option A: Acrylic is a synthetic fibre. Because of its resemblance to wool, acrylic is known as artificial wool or synthetic wool. Acrylic is less expensive than genuine wool and can be coloured in a wide range of colours. Acrylic is therefore quite popular among other fabrics. So, option A is correct.
Option B: Rayon was created as a silk substitute, and while being man-made, it is made from a natural resource - most typically wood pulp - and is far more wearable than polyester. Cotton sateen is another option. So, option B is incorrect.
Option C: Polyester and rayon are the most prevalent synthetic fibres blended with cotton in today's clothing. Spandex and nylon are also being woven into cotton blends to expand the range of apparel options. So, option C is incorrect.
Option D: Banana-plant fibre (Musa sapientum) is strong, soft, and coarse, and a method for processing it using normal jute machinery has been created. So, option D is incorrect.

Thus the correct answer is option ‘A’.

Note: Acrylic fibre is a synthetic material that has a similar appearance to wool. Acrylonitrile and a comonomer make up acrylic fibre. Vinyl acetate and methyl acrylate are common comonomers. Synthetic fibres have the advantage of being easily washed and dried. They’re less expensive than natural fibres and easily accessible. They don't wrinkle easily and are quite long-lasting.
