Question

Fabric made from which of the fibre does not get wrinkled easily?
A.Polyester
B.Acrylic
C.Nylon
D.Rayon

Answer 1

We also need to know that the fabric is a material which is made from the clothing. The silk is the common example of a fabric. And it is made up by using many materials like fibers, wool, silk, cotton, flax, jute etc. The wool and silk are collected from animals and cotton, jute and flax are mainly collected from plants and minerals are the sources of fibers. There are also some synthetic materials used for the preparation of fabric like polyester, rayon, acrylic, nylon etc.

Complete answer:
So much material is used for the preparation of fabric. Polyester is the main material which is used for the preparation of fibre so that the fibre does not get wrinkled easily. And the fibre can easily wash due to its crispiness. Therefore, polyester is a suitable material which is used for the preparation of dressing material. And we know, polyester is a synthetic fiber. Thus, it has high environmental resistance compared to other fibers. And it also has a high water content.
The polyester fibre can be prepared by the reaction of dimethyl terephthalate with ethylene glycol under the temperature $302 - {410^o}F$ in the presence of a catalyst. And there is a formation of monomer alcohol which is reacted with terephthalic acid at a high temperature and forms polyester fibre. Hence, option (A) is correct.
The acrylic is more carcinogenic. While it is used for the preparation of fibre, the skin will contact with this fibre. And it contains very less quantity of synthetic materials. Thus, it is not used widely for the preparation of fibre. Hence, the option (B) is incorrect.
The nylon is a synthetic polymer but it does not have the basis in organic material. And it is not stronger than polyester. Hence, option (C) is incorrect.
The rayon is not considered as a perfect fibre. Because, it absorbs the water contents very easily and it causes the breakage of fibre. Hence, the option (D) is incorrect.

Hence, option (A) is correct.

Note:
We must have to know that the fibers are in different types according to the sources of preparation. Mainly it is in four types and that is, animal, plant, synthetic and artificial. Animal, plant and synthetic are natural fibers. And the artificial fibre is made by using petroleum. In the case of synthetic fibre, the polyester is considered a perfect fibre. Because, it is more elastic and stronger and it does not attract the water.
