Worksheet 3: Class 6 Science - Fibre to Fabric

Welcome! This worksheet will help you understand how the clothes you wear are made. We will explore the journey from a simple fibre to a finished fabric. Let's learn about the different types of fibres and the processes they go through!

From Fibre to Fabric: The Journey

The thin strands of thread that we see are made of even thinner strands called **fibres**. Fibres can be broadly divided into two types:

• Natural Fibres: These are obtained from plants and animals. Examples include cotton, jute, silk, and wool.
  • **Cotton:** It is obtained from the cotton plant's fruit, called **cotton balls**. After picking, the seeds are separated from the fibres by a process called **ginning**.
  • **Jute:** This fibre is obtained from the stem of the jute plant. The plant's stem is soaked in water and allowed to rot, a process called **retting**, before the fibres are separated.
  • **Silk:** Silk is obtained from the cocoon of the **silkworm**.
  • **Wool:** Wool is obtained from the fleece of animals like sheep, goats, and yaks.
• Synthetic Fibres: These are man-made fibres. Examples are nylon and polyester.

The process of making yarn from fibres is called **spinning**. Then, the process of arranging two sets of yarns together to make a fabric is called **weaving**, which is done on machines called **looms**. Another method of making fabric is **knitting**, which uses a single yarn to create a piece of fabric.

Practice Questions

1. Fill in the blank: The process of separating cotton fibres from their seeds is called _____.

Ginning

2. True or False: Synthetic fibres are obtained from plants and animals.

False. Natural fibres are obtained from plants and animals. Synthetic fibres are man-made.

3. Match the fibre to its source:

(a) Jute (i) Sheep

(b) Wool (ii) Stem of a plant

(c) Silk (iii) Cocoon of a silkworm

a - ii, b - i, c - iii

4. What is the process of making yarn from fibre called?

Spinning.

5. Fill in the blank: _____ are the thinnest strands of a fabric.

Fibres

6. Explain the difference between weaving and knitting.

**Weaving** is the process of arranging two sets of yarns together to make a fabric. **Knitting** uses a single yarn to create a piece of fabric.

7. From which part of the cotton plant do we get cotton fibre?

From the fruit of the cotton plant, called **cotton balls**.

8. What is retting, and which fibre is obtained through this process?

Retting is the process of soaking the jute plant's stem in water to allow it to rot, which helps to separate the fibres. This process is used to obtain **jute** fibre.
