Question

1. define the following
a. spinning
b.cotton
c. jute
d.natural fibers
e. synthetic fibers​

Answer 1

Explanation:

(a) 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...

(b) Cotton : A soft fluffy usually white material made up of twisted hairs that surrounds the seeds of a tall plant of warm regions and is spun into thread or yarn..

(c) Jute : Jute is a very long fiber that comes from a plant and is used to make rugs, ropes, and other things. Jute twine feels coarse and rough, and is very strong. Jute is useful because of its length and cheapness — it provides an easy way to make an inexpensive sack or floor mat.

(d) Natural fibres : Fibres that are obtained from natural sources such as plants and animals are called natural fibres. Cotton, jute, coir, silk cotton, hemp and flax are examples ..

(e) Synthetic fibres : Synthetic fabrics and textiles made from man-made rather than natural fibres. Some examples of synthetic fabrics are polyester, acrylic, nylon, rayon, acetate etc ...

Answer 2

Answer:

:Spinning is the twisting technique where the fiber is drawn out, twisted, and wound onto a bobbin.

Cotton is a soft, fluffy staple fiber that grows in a boll, or protective case, around the seeds of the cotton plants of the genus Gossypium in the mallow family Malvaceae. The fiber is almost pure cellulose. Under natural conditions, the cotton bolls will increase the dispersal of the seeds.

Jute is a long, soft, shiny bast fiber that can be spun into coarse, strong threads. It is produced from flowering plants in the genus Corchorus, which is in the mallow family Malvaceae.

Natural fiber, hairlike material directly obtained from an animal, vegetable, or mineral source and convertible into nonwoven fabrics such as felt or paper ...

Synthetic fiber or synthetic fibre are fibers made by humans through chemical synthesis, as opposed to natural fibers that are directly derived from living organisms. They are the result of extensive research by scientists to improve upon naturally occurring animal and plant fibers.
