# Long Answer Type Questions :

Q. Write in sequence the steps involved in obtaining fabric from fibre.

Ans. The complete process of making or producing Fabrics from fibres includes:

a) Extraction of fibres either from the plant or animal source.

b) A group of filament or staple fibres extracted are twisted together to form a yarn.

c) These yarns are twisted tightly and weaved and knitted by passing a different number of yarns together to produce Fabrics.

# When two sets of yarn are involved, yarns are woven on looms to make a fabric. When a

single yam is used, the fabric is prepared by knitting.

Q. Describe the process of the formation of yarn from cotton wool.

Ans. The cotton wool is obtained from cotton plants. The cotton plants are grown in fields. They

are usually grown at the places having black soil and warm climate. The Fruit of the cotton plants

called cotton bolls are about the size of lemons. After maturing, the bolls burst open and seeds

covered with cotton fibres can be seen. From the cotton bolls cotton is picked by hands. Fibres

are then separated from the seeds by combing. This process is called ginning of cotton. It is

done by hand or by machines. These fibres are then converted into yarn by the process called

spinning.

Q. Describe the process of spinning and weaving.

Ans.

Spinning : 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. By this, fibres come together to form a yarn. Spinning can be done by hand, by takli and charkha. On a large scale, spinning is done with the help of machines.

Weaving : The process of arranging two sets of yarns together to make a fabric is called weaving. The process of weaving can be done on looms. The looms are either-hand operated or power operated.

Q. What is retting? Explain how fibres are obtained from the jute plants.

Ans. Jute plants are cut at the flowering stage when plants are 8-10 feet high. The cut plants are

grouped at different places in the field for few days when most of the leaves dry up and fall

down. The plants are now tied into small bundles. The bundles are made to sink in stagnant water of a pond for few days when the gummy skin rots out to separate fibres. This process is called retting. Fibre is extracted from the retted jute by hand, with jerks and pulls. The dried fibres are then tied together in small bundles.

Q. What is a loom? For what purpose is it used? What is the difference between handloom and

power loom?

Ans. A device which is used for making fabrics by weaving yarn or threads is called a loom. The

weaving of yarn to make fabrics is done by using looms.

The difference between handloom and power loom are:

(a) Handloom : It is a cloth weaving machine which is manually operated. In many parts

of our country, handloom cloth is produced in large quantities.

(b) Power loom : It is a medium-sized weaving machine that run on power supply. It is

used to produce cloth on large scale in cloth producing industries.

Q. What is meant by fibre and fabric? Describe the process of making fabrics from fibre.

Ans.

Fibre : A very thin, thread like strand from which yarn is made is called fibre.

Fabric : Fabric means a woven material resembling woven cloth. Fabric is made up of yarns.

Making Fabric :

The two main processes used for making fabrics are knitting and weaving.

1. Knitting : The process of making fabric by forming a series of connected loops of yarn is called knitting. This process is used for making sweaters, woolen caps, gloves, etc.

2. Weaving : The process of making fabric by crossing two sets of yarns over and under each other is called weaving. This process is used for making shirts, trousers, T-shirts, etc.
