GSEB Class 6 Science Solutions Chapter 3 Fibre to Fabric

Question 1. Classify the following fibres as natural or synthetic: nylon, wool, cotton, silk, polyester, jute.
Answer:

• Naturally occurring fibres: wool, cotton, jute, silk.
• Man-made fibres: nylon, polyester.

Exam Tip: Remember common examples for both natural (cotton, wool, silk, jute) and synthetic (nylon, polyester) fibres to easily classify them.

Question 2. State whether the following statements are 'True' or 'False':
(a) Yam is made from fibres.
(b) Spinning is a process of making fibres.
(c) Jute is the outer covering of coconut.
(d) The process of removing seeds from cotton is called ginning.
(e) The weaving of yam makes a piece of fabric.
(f) The silk fibre is obtained from the stem of a plant.
(g) Polyester is a natural fibre.
Answer:
(a) True
(b) False
(c) False
(d) True
(e) True
(f) False
(g) False
In simple words: You need to know the basic steps of how fabric is made and where different fibres come from to tell if these statements are correct or not.

Exam Tip: Be careful with statements about the origin of fibres (plant/animal/synthetic) and the correct terminology for textile processes like spinning, weaving, and ginning.

Question 3. Fill in the blanks:
(a) Plant fibres are obtained from ........... and ............
(b) Animal fibres are ........... and ...........
Answer:
(a) cotton plants, jute plants
(b) wool, silk
In simple words: Fibres from plants come from cotton plants and jute plants. Fibres from animals include wool and silk.

Exam Tip: Always remember the common sources for plant fibres (cotton, jute) and animal fibres (wool, silk) as these are frequently asked.

Question 3. From which part of the plant cotton and jute are obtained?
Answer:
Cotton – Cotton bolls (from the surface of cotton seeds) (fruit)
Jute – Stem
In simple words: Cotton comes from cotton bolls, which grow on the plant as a fruit. Jute is obtained from the stem of the jute plant.

Exam Tip: It is crucial to know the specific plant parts from which different natural fibres are gathered, such as cotton from bolls and jute from stems.

Question 4. Name two items that are made from coconut fibre.
Answer:

• Ropes
• Mats

Exam Tip: Focus on practical applications of natural fibres. Coconut fibre (coir) is often used for sturdy items like ropes and mats.

Question 5. Explain the process of making yarn from the fibre.
Answer: Yarns are made up of thin strands called fibres. The process of making yarn from fibres is called spinning. During this method, a lump of cotton wool is pulled out and spun. This joins the fibres to create yarn.
In simple words: Yarn is made from thin fibres. We make yarn from fibres by a process called spinning. In spinning, cotton wool is pulled and twisted to join the fibres together, forming yarn.

Exam Tip: Clearly define spinning as the process of converting fibres into yarn and describe the key actions involved (drawing out and twisting fibres).
