Question

Which of the following is a source of rayon?
A.Wool
B.Wood pulp
C.PET
D.Silk

Answer 1

Hint: Rayon is a man-made or synthetic fiber. It has an appearance similar to silk and can be woven like silk fibers as well. Fabrics made using rayon are soft, smooth, comfortable, highly absorbent and cool as they do not insulate body heat. Thus it is ideal for use in humid climates.

Complete step by step solution:
Rayon is a natural based man made fabric that is made from cellulose generally obtained by wood pulp. It is described as regenerate fiber due to the reason that the cellulose is first converted into a liquid compound, then squeezed through a spinneret (device having tiny holes) and later converted back to cellulose as fibers. Rayon fibers are versatile fibers claimed to provide the same level of comfort properties like natural fibers. Rayon can imitate the texture and feel of various natural fibers like silk, wool, linen and cotton. Also, it can be dyed easily in a vast range of colors.

The correct option is B.

Note:
1.Natural fibers are fibers obtained from natural sources like plants and animals. Various natural fibers are cotton, silk, wool etc.
2.Synthetic fibers are those fibers that are made by human beings in laboratories. They are polymers formed by repeating units of various monomers. Various synthetic fibers commonly used are nylon, acrylics and polyesters. Synthetic fibers are preferred as they are durable and elastic. Synthetic fibers are strong, soft and cheaper as compared to natural fibers.
