NCERT Solutions PDF Class 6 PDF

CBSE Class 6 Science Chapter 3, 'Fibre to Fabric,' introduces students to the diverse world of materials that make up our clothes. This chapter explores the journey from raw fibres to finished fabrics, explaining the differences between natural and synthetic fibres. You'll discover where fibres like cotton and jute come from (plants) and how others, such as silk and wool, are derived from animals. The solutions detail the processes involved, like spinning yarn from fibres and weaving yarn into fabric. Understanding concepts such as ginning, which separates cotton fibres from seeds, is also covered. These explanations are designed to help you grasp the basics of textiles, making your studies clearer and preparing you well for exams.

Chapter summary

Chapter 3, 'Fibre to Fabric,' focuses on the basic understanding of fibres and their transformation into fabrics. The NCERT Solutions cover the classification of fibres into natural and synthetic types, identifying sources like plants and animals for natural fibres. It explains key processes such as ginning cotton and spinning yarn, and the creation of fabric through weaving. The solutions also touch upon the uses of fibres derived from plants like jute and coconut.

Questions and Solutions

Question 1

Classify the following fibres as natural or synthetic: nylon, wool, cotton, silk, polyester, jute
Solution:

Fibres can be classified based on their origin into two main types: natural and synthetic.

Natural Fibres: These fibres are obtained from natural sources, either plants or animals.

  • From the given list, the natural fibres are: wool (from animals), cotton (from plants), silk (from animals), and jute (from plants).

Synthetic Fibres: These fibres are man-made and are produced through chemical processes.

  • From the given list, the synthetic fibres are: nylon and polyester.

Question 2

State whether the following statements are true or false: a) Yarn 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 seed from cotton is called ginning. e) Weaving of yarn makes a piece of fabric. f) Silk fibre is obtained from the stem of a plant. g) Polyester is a natural fibre.
Solution:

Let's evaluate each statement:

a) Yarn is made from fibres. (True)

Explanation: Yarn is a continuous strand made by twisting fibres together.

b) Spinning is a process of making fibres. (False)

Explanation: Spinning is the process of making yarn from fibres, not making fibres themselves.

c) Jute is the outer covering of coconut. (False)

Explanation: Jute fibre is obtained from the stem of the jute plant. The outer covering of coconut is called coir.

d) The process of removing seed from cotton is called ginning. (True)

Explanation: Ginning is the method used to separate the cotton fibres from the cotton seeds.

e) Weaving of yarn makes a piece of fabric. (True)

Explanation: Weaving is a process where yarns are interlaced to create fabric.

f) Silk fibre is obtained from the stem of a plant. (False)

Explanation: Silk fibre is obtained from the cocoon spun by silkworms, which are animals.

g) Polyester is a natural fibre. (False)

Explanation: Polyester is a synthetic fibre, meaning it is man-made.

Question 3

Fill in the blanks: a) Plant fibres are obtained from _____ and ____. b) Animals fibres are _____ and _____.
Solution:

We can fill in the blanks based on the sources of fibres:

a) Plant fibres are obtained from cotton (from the fruit/boll) and jute (from the stem).

b) Animal fibres are wool (from sheep, goats, etc.) and silk (from silkworms).

Question 4

From which parts of the plant cotton and jute are obtained?
Solution:

The parts of the plant from which cotton and jute are obtained are:

  • Cotton: Cotton is obtained from the fruits of the cotton plant. These fruits are often called cotton balls or bolls.
  • Jute: Jute fibre is obtained from the stem of the jute plant. The fibres are extracted after the plant is harvested and processed.

Question 5

Name two items that are made from coconut fibre.
Solution:

Coconut fibre, also known as coir, is a coarse fibre extracted from the outer husk of coconuts. It is used to make several useful items, including:

  • Jute bags (Note: While the question asks for coconut fibre items, the source incorrectly lists 'Jute bags'. Correcting this to common coir products.) Ropes
  • Foot mats
  • Other items include brushes, doormats, and stuffing for mattresses and upholstery.

Question 6

Explain the process of making yarn from fibre.
Solution:

The process of making yarn from fibres is called spinning. Here's how it works:

  1. Drawing out: Fibres are taken from a mass of cotton (or other fibre).
  2. Twisting: These fibres are then drawn out and twisted together. The twisting action helps to bind the fibres closely, giving them strength and coherence.
  3. Yarn Formation: This continuous process of drawing and twisting results in the formation of a strand of yarn.

Spinning can be done using simple hand-operated devices like the hand spindle (takli) and the charkha, which were traditionally used in homes. On a larger scale, industrial spinning machines are used to produce yarn efficiently in textile mills.

Common mistakes

  • Confusing spinning (making yarn from fibres) with making fibres.
  • Incorrectly identifying the source of jute fibre (e.g., confusing it with coconut husk).
  • Mistaking synthetic fibres for natural ones, or vice versa.
  • Not understanding that yarn is made from fibres, not the other way around.

Revision tips

  • Create flashcards to distinguish between natural and synthetic fibres and their sources.
  • Draw diagrams to illustrate the processes of ginning and spinning.
  • Practice classifying the given fibres in the exercises.
  • Review the definitions of key terms like yarn, fibre, and fabric.

Frequently asked questions

What is the main difference between natural and synthetic fibres?

Natural fibres are derived from plants and animals (like cotton, wool, silk, jute), while synthetic fibres are man-made, usually from chemical processes (like nylon, polyester).

How is yarn made from fibres?

Yarn is made through a process called spinning, where fibres are drawn out from a mass of cotton (or other fibre) and then twisted together to form a continuous strand called yarn.

What are the two main sources of plant fibres?

Plant fibres are primarily obtained from two parts of plants: the stem (like jute and flax) and the fruit or boll (like cotton).

What is ginning?

Ginning is the process of separating cotton fibres from their seeds after the cotton bolls have been harvested.

Can you give examples of items made from jute fibre?

Yes, common items made from jute fibre include bags (like jute sacks), ropes, mats, and some types of carpets and clothing.

What is the role of a charkha in making yarn?

A charkha is a simple, traditional device used for spinning fibres into yarn by hand. It was famously promoted by Mahatma Gandhi.
