Learning Objectives
1. To study different types of clothing materials
2. To understand the concept of fibres ,fabric and yarn
3. To know different sources to get fibres
4. To study different plants, animals and synthetic fibres
5. To understand different methods to get fabric from yarn
6. To know history of clothing

We wear clothes to protect our body against heat, cold,rain,dust and insects.At the same time we wear clothes to look good .That is why many of us want to
wear clothes that are in fashion. People in different regions of the world wear different kinds of clothes. The kind of clothes people wear mainly depends on the climate of the place. The traditional clothes worn by people in our country vary considerably from region to region.
People living in hot countries wear light clothing. During summer we should wear loose fitting clothes to keep our body cool.People living in cold countries wear woollen clothes like –coats, jersys, socks, caps etc.Dark coloured clothes are worn in winters because they absorb heat and warm quickly.

FABRICS
Fabrics are materials made from weaving, knitting, spinning fibres together.. Often the fibres are spun or wound together to form a thread before being made into a fabric. The nature of a fabric will depend on the fibres from which it is made and the way that they are arranged, and its properties will determine the applications for which it is suitable. Cotton,wool,silk etc. are examples of fabrics.

YARN
It is made up of fibres. Yarn is a long continuous length of interlocked fibres, suitable for use in the production of textiles, sewing, knitting, weaving, embroidery, and rope making. Thread is a type of yarn.

FIBRES
A fibre a is thread which is strong and flexible enough to make clothes.
Fibres can be broadly classified as natural fibres and synthetic fibres e.g.
Natural fibres : Cotton, Wool, Silk, Pure jute etc.
Synthetic fibres : Nylon, Polyester, Acrylic etc.

Sources of Natural Fibres
Natural fibres are obtained from
(i) Plant sources : cotton, jute.
(ii) Animal sources : wool, silk

PLANT FIBRES
Cotton ,sisal,flax,jute,ramie,coir and hemp are examples of plant fibres.They have more extensive use than animal fibres Cotton
Cotton is a soft fibre that is obtained from cotton plant. Cotton is generally grown in such places that have black soil and warm climate. The fruits of cotton plant are called cotton bolls. They are of the size of a lemon. After maturing cotton bolls open and we can easily see the seeds covered with cotton fibres. From cotton bolls, cotton is usually picked by hand.
Advantage of cotton is that the sweat it absorbs evaporates .This results in cooling down of the body.Cotton clothes are therefore, comfortable to wear especially in hot, humid weather.
In India cotton is sown between May and September in different parts of the country. The harvesting begins from October.
In India, the states of Maharashtra (26.63%), Gujarat (17.96%) and Andhra Pradesh (13.75%) and also Madhya Pradesh are the leading cotton producing states, these states have a predominantly tropical wet and dry climate.

Ginning of cotton : It refers to the process of separation of cotton fibres from the seeds.
Ginning of cotton was previously done by hand but these days machines called cotton gins are used for this purpose.
A cotton gin is a machine that quickly and easily separates cotton fibers from their seeds.
Cotton fibres are then combed, straightened and form rope like strands called silver.

Jute
It is a natural fibre obtained from jute plant. It is obtained from stem of jute plant. Jute is the cheapest natural fibre.It grows very well in alluvial and loamy soil.
It is cultivated during raining season. In India jute is mainly grown in states of West Bengal (W. B), Bihar, Assam. Jute plant is normally harvested when it is at flowering stage. To get jute, the stems of the harvested plants are immersed in water for a few days. The stems rot and then fibres are separated by hand. This process is called retting. Jute is 100% bio-degradable and recyclable and thus environment-friendly. It can be an effective substitute for plastic bags. It is used to make sacks, ropes, handmade clothes ,wall hangings and for making strong packing materials.

SOME OTHER IMPORTANT PLANT FIBRES

Coir
It is the fibre obtained from the outer cover of the fruit of the coconut palm.
There are two types of coir: brown fibre,(from ripe coconut) and finer white fibre(from raw coconut).Coir is used in sacking and doormats, mattresses ,for making finer brushes string, rope and fishing nets. India and Sri Lanka are major producers of coir.

Flax
It is obtained from stem of flax plant.The fabric made from flax fibre is called linen.It is used for making clothes,ropes and high quality paper.

Sisal
Sisal fibres are obtained from the leaves of the sisal plant. These fibres are used in the production of ropes, nets and matting.

Ramie
Ramie is obtained from the stem of the Ramie plant. Ramie fibres are used in the production of canvas, sewing threads, fishing nets, and parachutes

Hemp
Hemp fibres are obtained from the stem of the hemp plant. Hemp plants grow best in loamy soil. Hemp fibres are used in the production of ropes, carpets, nets, clothes, and paper. These fibres are also used to make a special kind of plastic.

ANIMAL FIBRES
Wool and silk are examples of animal fibres .

Wool
Wool is the fibre derived from the hair of sheep and some other animals like angora rabbit, yak, Llama,camels and musk oxen.

Silk
Silk is obtained from the cocoon of the silkworm. Silkworms are fed on the leaves of the mulberry trees.Cocoons are dissolved in boiling water in order to extract individual long fibres .

SYNTHETIC FIBRES
Synthetic fibres are not obtained from plants or animals. These are made from chemical substances. Rayon, nylon and dacron are examples of synthetic fibres.

Advantages of Synthetic Fibres
Clothes made from synthetic fibres are strong and do not wrinkle easily.They also dry easily .

Disadvantages of Synthetic Fibres
They have less air spaces in them than natural fibres They also cannot absorb sweat easily.These properties make them unsuitable for hot and humid weather.

FIBRE TO YARN

Spinning
The process of making yarn from fibres is called spinning. To get cotton yarn, fibres from a mass of cotton wool are drawn out and twisted. This brings fibres together to form a yarn. Spinning wheel (Charkha) or hand spindle are used for spinning process.

Hand spindle : It is a simple device used for spinning of cotton. It is called takli.

Charkha: It is also a hand operated device used for spinning of cotton. 
The charkha was both a tool and a symbol of the Indian independence movement.When India was a colony of Britain, Indian cotton was shipped to Britain and the Indians had to buy it back as fabric. Gandhi promoted spinning as an act of independence. He encouraged people to wear self spun clothes and reject the cloth made in Britain.

YARN TO FABRICS
For making fabric from yarn following two processes are used
(i) Weaving
(ii) Knitting

Weaving
The process of arranging two sets of yarns together to make a fabric is called weaving.
The device used for weaving is called looms .The looms are either hand operated called handlooms or power operated called power looms.

Knitting
For knitting, a single yarn is used to make a piece of fabric. Knitting is done by hands and also on machines.
Different types of needles are used for knitting purpose.

HISTORY OF CLOTHING
In ancient times people used bark and big leaves of trees or animal skins and furs to cover themselves. About 30,000 years ago, people started using animal skins for clothing. Animal skins were either worn as capes thrown around the shoulders or as two skins tied at the shoulder. After people began to settle in agricultural communities. They learnt to weave twigs and grass into mats and baskets. Vines, animal fleece or hair were twisted together into long strands. These were woven into fabrics. Thousands of years ago, people learned how to obtained fibres from wild plants. These fibres were spun into thread and made into clothes. Archaeologists have discovered fragments of plant fibres in Switzerland, which date back to around 8000 BC. It indicates that people began to weave fabrics around 8000 BC.
Early Indians wore cotton fabrics. In India cotton grew in the regions near river Ganga. Flax is a plant that gives natural fibre. In Egypt, in ancient times, cotton as well as flax were cultivated near river Nile.

WAYS OF USING FABRICS

Draping
In ancient days, stitching was not known and people simply draped the fabrics around different parts of their body Even today, Saree, dhoti, lungi or turban is used unstitched.

Stitching
After invention of stitching needle, people started stitching fabrics to make clothes.
