CBSE Case Study Questions Class 6 Science Fibre to Fabric

Case study 1

The thin strands of a thread are made up of even thinner strands called fibres.Fabrics are made up of yarns and yarns are further made up of fibres.

The fibres of some fabrics such ascotton, jute, silk and wool are obtainedfrom plants and animals. These arecalled natural fibres. Cotton and juteare examples of fibres obtained fromplants. Wool and silk fibres are obtainedFrom animals. Wool is obtained from thefleece of sheep or goat. It is also obtainedfrom the hair of rabbits, yak andcamels. Silk fibre is drawn from theCocoon of silkworm.For thousands of years natural fibres were the only ones available for making fabrics. In the last hundred years or so, Fibres are also made from chemical substances, which are not obtained from plant or animal sources. These are called synthetic fibres. Some examples of synthetic fibres are polyester, nylon and acrylic.

Case study 2

Cotton is grown in the fields. Cotton plants are usually grown at places having black soil and warm climate. The fruits of the cotton plant (cotton bolls) are about the size of a lemon. After maturing, the bolls burst open and the seeds covered with cotton fibres can be seen. A cotton field that is ready forpicking, looks like a field covered with snow.From these bolls, cotton is usually picked by hand. Fibres are then separated from the seeds by combing. This process is called ginning of cotton. Ginning was traditionally done by hand. These days, machines are also used for ginning.

Jute fibre is obtained from the stem of the jute plant. It is cultivated during the rainy season. In India, jute is mainly grown inWest Bengal, Bihar and Assam. TheJute plant is normally harvested when it is at flowering stage.The stems of the harvested plants are immersed in water for a few days. The stems rotand fibres are separated by hand.

Que.4)Answer:Cotton is usually picked by hand from the cotton fields. Fibres are then separated from the seeds by combing. This process is called ginning of cotton.

Que.5) Answer: Jute plantsare cultivated during the rainy season.

In India, jute is mainly grown in West Bengal, Bihar and Assam.

Case study 3

The process of making yarnfrom fibres is called spinning.In this process, fibres from amass of cotton wool are drawnout and twisted. This bringsthe fibres together to forma yarn.A simple device usedfor spinning is a handspindle, also called takli. Another handoperated device used forspinning is charkha. Use of charkha waspopularised by MahatmaGandhi as part of theIndependence movement. He encouraged people to wearclothes made of homespun yarn termedas khadi and shun imported cloth madein the mills of Britain. To popularise andpromote khadi, the Government of Indiaconstituted a body called Khadi andVillage Industries Commission in 1956.

Spinning of yarn on a large scale isdone with the help of spinningmachines. After spinning, yarns areused for making fabrics.

Que.3) Clothes made of homespun yarn were termed as khadi?

a) True

b) False

Que.4) Explain the process of spinning?

Que.5)Who popularised the use of Khadi? Why?

Answer Key

Que.1.b)False

Que.2. b) Takli

Que.3. a) True

Que.4) Answer: The process of making yarn from fibres is called spinning. In this process, fibres from a mass of cotton wool are drawn out and twisted. This brings the fibres together to form a yarn.

Que.5)Answer: MahatmaGandhi popularised the use of Charkha as part of the Independence movement. He encouraged people to wear clothes made of homespun yarn termed as khadi and shun imported cloth made in the mills of Britain.

Case study 4

There are many ways by which fabrics are made from yarns. The two main processes are weaving and knitting.The process ofarranging two sets of yarns together tomake a fabric is called weaving. Weaving of fabric is done on Looms. The looms are either Hand operated or power operated.

In knitting, a single yarn is used to make a piece of fabric.

For instance, if you pull the yarn from a Torn pair of socks, you will see that A Single yarn gets pulled out continuously as the fabric gets unravelled. Socks and Many other clothing items are made of Knitted fabrics. Knitting is done by Hand and also on machines.

Case study 5

It appears that in ancient times people used the bark and big leaves of trees or animal skins and furs to cover themselves. 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. The early Indians wore fabrics made out of cotton that grew in the regions near the river Ganga. Flax is also a plant that gives natural fibres.

In ancient Egypt, cotton as well as flax were cultivated near the river Nile and were used for making fabrics. In those days, stitching was not known. People simply draped the fabrics around different parts of their body. Many different ways of draping fabrics were used. With the invention of the sewing needle, people started stitching fabrics to make clothes. Stitched clothes have gone through many variations since this invention. But, it is amazing that even today saree, dhoti, lungi or turban is used as an un-stitched piece of fabric.
