Question 4 (Textile Technology & Fibre Science)

Cotton fibre has maximum amount of cellulose in

(B)Primary cell wall
(C)Secondary cell wall
[Show Answer]

Option C is correct.
The outer layer of the cotton fiber, known as the secondary cell wall, has the highest concentration of cellulose. This layer provides the strength and rigidity to the cotton fiber, making it ideal for spinning into yarns and weaving into textiles. The inner layer, known as the primary cell wall, is thinner and less structured than the secondary cell wall, but still contains a significant amount of cellulose.

In cotton fibers, cellulose is arranged in a highly organized manner, with long chains of glucose molecules held together by hydrogen bonds. This structure contributes to the strength and rigidity of the cotton fiber, making it a highly valued material in the textile industry.

Overall, the secondary cell wall of the cotton fiber is the part of the fiber that has the highest concentration of cellulose, and this concentration is what gives cotton its unique properties and makes it so widely used in the textile industry.

Cotton fibers have the highest amount of cellulose among natural fibers. Cellulose is the main structural component of plant cell walls and is what gives cotton fibers their strength and rigidity. In cotton fibers, cellulose accounts for around 90-95% of the fiber’s total weight. The high cellulose content of cotton fibers is one of the reasons why cotton is one of the most widely used natural fibers in the textile industry. It is valued for its softness, absorbency, and strength, making it an ideal material for a wide range of products, including clothing, towels, and bedding.

Frequently Asked Questions | FAQs

What is Cellulose ? | What is a cellulose simple definition?

Cellulose is a complex carbohydrate that is an essential structural component of the cell walls of green plants and some algae. It is the most abundant organic compound on Earth and serves as a major source of dietary fiber for humans and animals.
Chemically, cellulose is a linear polymer of glucose molecules linked together by β-1,4-glycosidic bonds. The repeating unit in cellulose is cellobiose, which consists of two glucose molecules linked by a β-1,4-glycosidic bond.
Cellulose is a tough, insoluble, and indigestible material that provides rigidity and strength to plant cell walls. It is also used in the production of paper, textiles, and other materials. Because of its fibrous nature, cellulose is an important dietary component that helps to promote digestive health and prevent certain diseases.
