The different varieties of clothes or fabrics are cotton, woollen, silk and synthetic etc. This chapter is all about variety in fabrics, how these fabrics are made, what are different types of fibres, how are fibres processed to form yarn and how yarn is made into fabrics and what is the history of clothing material. 

Variety in Fabrics

There is a large variety of fabrics found in the cloth shops in the market. The most common types of fabrics used by us are:

• Cotton Fabrics.
• Woollen Fabrics.
• Silk Fabrics.
• Synthetic Fabrics.

Fibre

If we have a close look at a piece of fabric, we will find that it is made up of yarns or threads and if we try to unfold a thread or yarn we will see that yarn or thread is further made up of very thin and fine strands called fibres. Fibre is the basic unit of fabric. The fibres are broadly classified as

1. Natural Fibres —-Plant and Animal Fibres
2. Synthetic Fibres — Polyester, Nylon, Acrylic.

Some Plant and Animal Fibres

Plant Fibres: The fibres like cotton, jute and flax which are contained in plants are called plant fibres.

Animal Fibres: The fibres like wool and silk which are obtained from sheep and silkworms are termed animal fibres.

Spinning Cotton Yarn

The process of making yarns from fibres is called spinning. In this process, the fibres from a mass of cotton, wool or silk are drawn out and twisted. It brings the fibres together to form yarn. The process of making yarn from fibres can be completed by using these three devices:

1. Hand Spindle (Takli)
2. Spinning Wheel (Charkha)
3. Spinning Machines.

Yarn to Fabric

After producing yarns through the process of spinning. These yarns are used to make fabrics which are used for making clothing items. There are many ways of making fabrics from yarns but the two most common and widely used methods for making fabrics from yarns are:

1. Weaving: It is a process of making fabrics from two sets of yarns by arranging them at right angles to each other. It can be done by looms, handlooms or power looms.

2. Knitting: The process of making fabric by interlocking the loops of the yarn using knitting needles or machines is called knitting. A single yarn is used to make fabric in the case of knitting and pulling out a single yarn can unravel the fabric.

History of Clothing Material

In ancient times, people do not use to wear clothes. During those times people used the bark of trees, big leaves of trees, animal skin and furs to cover their bodies.

After the people began agricultural practices and the development of settled communities, they learnt to weave twigs and grass into mats and baskets. After that people used fabrics woven out by twisting vines and animal fleece. Later on, people started growing cotton. The early Indians wore fabrics made out of cotton that grew in regions near the river Ganga. In the early days, people used to wear unstitched clothes. After the invention of the sewing needle, people started using stitched clothes.
