Question

Pull a single thread from any piece of cloth. What are these fibres or threads made up of?

Answer 1

Hint: We know that cloth is made from interweaving the twisted fibres together. The twisted fibres are termed yarn. So, fibres come together to make a yarn and finally, yarn is entwined to make the cloth fabric. To find the type of fibre, observe the fabric.

Complete answer:
Fibre is the basic unit of fabric. The type of fabric is determined by the nature of the fabric. We know that fibres are briefly classified into two categories depending on the origin of their fibre.
Types of Fibre (basis of origin) is classified as follows:
1.Natural fibre
2.Synthetic fibre
Both of the fibres are differentiated on how they originate. Let’s have a look at each of these fibres.

Natural Fibres	Synthetic Fibres
This fibre is derived from either plants or animals.	This fibre is made artificially in factories using chemicals.
Examples: Plant origin- Cotton, jute. Animal origin- wool, silk.	Examples: Nylon, acrylic and polyester.
Fabric obtained from natural fibres is more comfortable.	Fabric made from synthetic fibres is heavy and uncomfortable.
Pure natural fibres are expensive and take time for its manufacturing.	Synthetic fibres are available in abundance so they are cheap and are produced in a short time.

Therefore, if you pull a piece of thread or fibre from any piece of cloth, you will find the fibre of any type of fabric like cotton, nylon, terry cot, silk, etc.

Note:
Remember the steps to make a fabric of any type. Initially, for natural fibres, the plant balls go through ‘ginning’ where the fibres are segregated from the seeds. This usually takes place with cotton balls. Further, the fibre is twisted to make the yarn. These yarn strands are weaved together to make the final cloth fabric.
