Important Questions Class 6 Science Chapter 3 – Fibre to Fabric

Science is a subject which is all about learning and discovering new things. ‘Fibre to Fabric’ is the third chapter in the Class 6 Science syllabus. To produce a garment, raw material is turned into fibre, then the fibre is turned into yarn, and then the yard becomes fabric. The process of making cloth or fabric by arranging yarns at right angles to them is called weaving. Following spinning and dying, the weaving process enables the yarn to intersect to become fabrics. These fabrics can be made either naturally or synthetically based on the source of origin. Natural fabrics are obtained from fibres of natural origin, and synthetic fabrics are made of man-made or artificial fibres.

Question 2.

What is a loom? For what purpose is it used? What is the difference between handloom and a power loom?

Answer 2: 

 A loom is a device for weaving yarn or threads into fabric. It is used for making fabrics. There are two types of looms. They are handlooms and power looms. 

The difference between handloom and a power loom are:

Handloom: A handloom is a manually controlled machine for weaving textiles. Large amounts of handloom cloth are produced throughout our nation.

Powerloom: A power loom is a medium-sized weaving machine powered by an electrical source. It is employed in large-scale fabric production enterprises. 

Question 3. What are the advantages of synthetic fibres? 

Answer 3: The advantages of Synthetic fibres are:

• It has good elasticity.
• It is very strong and durable.
• It is easy to dry.
• It is wrinkle-resistant. 

Question 4. What is retting? 

Answer 4: Retting is the technique of utilising different microorganisms to separate fibres that are tightly bound together. In this method, moisture and microbial activity on plant fibres are used. Jute, for instance, is connected to the retting process.

Question 5. Name two items that are produced from coconut fibre.  

Answer 5: Two items that are produced from coconut fibre are : 

(i) Ropes

(ii) Mats

Question 6. Explain the process of making yarn from fibre.

Answer 6: Fibres are the tiny strands that make up yarns. Spinning is the process of creating yarn from fibres. A large quantity of cotton wool is drawn out and twisted during this process. As a result, yarn is created from woven fibres.

• Dhoti
• Lungi
• Saree and 
• Turban.

Question 10. What are the fruits of cotton plants called?
