Answer 1

Correct Answer - Option 4 : Rayon

Explanation:

• Synthetic fibers are man-made fibers, most of them are prepared from raw material petroleum called petrochemicals.
• All fabrics are obtained from fibers, while fibers are obtained from artificial or man-made sources. 
• They consist of a small unit or a polymer which is made from many repeating units known as monomers.
• They include nylon, acrylics, polyurethane, and polypropylene. Millions of tons of these fibers are produced all over the world each year.
• The modern textile industry is unthinkable today without synthetic fibers. Man-made fibers like silk have always been greatly valued for its gloss and fineness. Man-made fibers are smooth.
• They can be distinguished by looking at a cross-section. Some of the synthetic fibers are rayon, nylon, polyester, etc. This fiber finds its applications in household articles like ropes, buckets, furniture, etc.

 

Advantages	Disadvantages
They are very durable and do not wrinkle easily. They are elastic and can be easily stretched out. They are strong and can sustain the heavy load. They are soft and hence used in clothing material. They are cheaper as compared to natural fibers.	Most synthetic fibers do not absorb moisture. Synthetic fiber can be affected if washed using hot water. They are non-biodegradable and offer poor insulation.
