Given below are two groups of material used to make dress articles. On what basis these have been grouped?
Jute ,Cotton
Wool,Silk’Leather
(A) Synthetic
(B) Natural
(C) Both A and B
(D) None of the above
Solution
Most of the fabric materials are of natural origin. There are many sources to obtain natural products.
For example, from plants, animals, etc.
They are called biotic resources.
Complete step by step answer:
Let's understand all the given materials in detail.
- Jute
Jute fibres are obtained from the plant corchorus olitorius and corchorus capsularis.
Jute plant cultivation and jute production rank second after cotton.
The fires are separated from the stalk of the plant and then are sent to the jute mills where the jute yarn is made.
Jute is used for making clothes, ropes and different household products. - Cotton
Cotton stands first in the production of crops.
Once the cotton crop is harvested, the cotton stalks are chopped off and sent to factories to make cotton threads.
It is used to make a number of textile products. It is also being used for the production of fishing nets, coffee filters, tents, explosive manufacture, cotton paper, etc. - Wool
Wool is obtained from various animals like sheep, goats, and camelids.
It is a natural fibre that covers most of the body of the concerned animals.
It consists of a small number of lipids along with proteins.
It provides excellent protection from heat. Hence, is used to make sweaters, thermal wears - Silk
Silk fibres are obtained from cocoons made by silkworms.
The cocoons are made up of sericin, a substance secreted by the silkworms.
Silk fibres are strong and are used to make sarees, shirts and various other clothes.
Silk cloth is one of the most expensive fabrics. - Leather
It is obtained from animal skins and hides.
It is durable and quite flexible and is used in making shoes, wallets, belts, etc.
Now, we can see that all the above fabric materials are obtained from nature but jute and cotton are from plant origin and silk, wool, leather are from animal origin.
So, the two groups are classified on the basis of their extraction from plants or animals.
Hence the correct answer is B.
Note: The fabric materials here are distinguished based on their origin.
All of the above-mentioned fibres are natural fibres.
Synthetic fibres are man-made fibres, mostly made up of small units of polymer and raw material petroleum called petrochemicals.
Examples of synthetic fibres are polyester, rayon, spandex, acrylic fibres, microfiber, etc.
