Fibre to fabric of class 6
1.
2. INTRODUCTION: If you will visit any cloth shop, you will observe that
varieties of clothes are available there like bed sheet, blankets, curtains,
tablecloths, towels and dusters. Now if you separately touch each of the
cloth you will observe that the nature of the clothes are different i.e they
are made of different kind of fabrics. Now you may wonder with the word
‘fabric’ because you know the term but probably you don’t know the
details of fabric or the formation of it. So, throughout the chapter we will
learn about this.
HISTORY OF CLOTHING MATERIAL: The concept of clothing
material has started from the ancient time when the people used the bark
and big leaves of trees or animal skins and furs to cover themselves. As
people have learned different things then the concept or way of clothing
was also changed. The early Indians wore fabrics made out of cotton that
grew in the regions near the river Ganga. In ancient Egypt, cotton as
well as flax were cultivated near the river Nile and were used for making
fabrics. With the invention of the sewing needle, people started stitching
fabrics to make clothes. Stitched clothes have gone through many
variations since this invention.
3. A fibre is a thin thread of a
natural or artificial substance,
especially one that is used to
make cloth or rope. If you pull
any cotton fabric you will find
that it is made of some thin
threads, called yarn which are
further can be separated into
thinner strands that are called
fibre.
What is fibre?
5. Natural fibre: The fibres which are obtained from plant and animals
are called natural fibres. Example: Cotton Wool, Jute & Silk
Cotton
Silk
Wool
Jute
6. Synthetic or man-made fibre: The fibres that are synthesized in
laboratory are called Man-Made or Synthetic Fibres. Example: Nylon,
Polyester, Makmal, Fur etc.

7. Natural Fibres
COTTON:
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. From these bolls, cotton is usually picked by hand.
8. Process of Making Cotton: From field to fabric
The process of making cotton transforms the raw fibers into threads, yarn
and fabric in three steps: Preparation, Spinning, and Weaving.
9. Fibres are 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.
10. JUTE
Jute fibre is obtained from the stem of the jute plant. It is cultivated during
the rainy season. In India, jute is mainly grown in West Bengal, Bihar and
Assam. The stems of the harvested plants are immersed in water for a few
days. The stems rot and fibres are separated by hand.
11. 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.
This brings the fibres together to form a yarn. A simple device used for
spinning is a hand spindle, also called takli. Another hand operated
device used for spinning is charkha.
12. Spinning of yarn on a large scale is done with the help of spinning
machines. After spinning, yarns are used for making fabrics.
13. Weaving
Weaving is a method of textile production in which two distinct sets of
yarns or threads are interlaced at right angles to form a fabric or cloth.
Other methods are knitting, crocheting, felting, and braiding or plaiting.
The longitudinal threads are called the warp and the lateral threads are
the weft or filling.
14. HOMEWORK ON FIBRE TO FABRIC

for cotton production.
4.What is retting?
5.What is spinning?
6.What is ginning?
7.Write down the name of Indian states that
are famous for jute production.
