Question

Which of the following fibre is obtained by flax seeds?
(A) Silk.
(B) Cotton.
(C) Linen.
(D) Polyester.

Answer 1

Hint :We know that the Linen is an example of best fibres. It is stronger than other fibres and is used in making fabrics. It is absorbent and dries faster than other natural fabrics. The fibre obtained is rich in cellulose.

Complete Step By Step Answer:
Fibres are long, tapering cells which die at maturity. It is mostly composed of cellulose and lignin. It is used to make fabrics. They can be obtained from both the plant and animal sources. Plant sources include jute, cotton. Animal sources include wool from the sheep, silk from silkworm.
Linen is a best fibre which is found behind the bark in the stem of the flax plant. The flax plant is grown in the temperate and subtropical regions. The linen fibres are longer than the jute fibres. The woody stem, the inner pith holds the fibres together in a clump and needs to be rotted in order to obtain fibre. The length of the fibre varies from $ 1\text{ }to\text{ }6 $ inch and is around $ 12-16 $ micrometers in diameter. The fibre is used for making fabrics both fine and coarse. The fibres are used to produce threads, cordage and also twine.
Chia seeds: It is an edible seed which is rich in minerals like calcium. It is rich in dietary fibre and is used as a cure for constipation. Cotton seeds: It is an important seed for extracting oil. It is also edible like chia seeds. The cake of the seed is fed to the cattle after extracting oil. The cotton seed oil is used as a lubricant.
Therefore, correct answer is option C i.e. Linen is fibre obtained from flax seeds.

Note :
Remember that Flax fibre is soft, shiny and flexible. It is less elastic than cotton. The coarser grade of fibre is used for making ropes, canvas and webbing equipment. Fine grade is used for making fabrics. It is also used to make high quality paper, blotting and filter paper and paper for cigarettes, tea bags.
