Question

Linen fibre is obtained from __________.
A)Chia seeds
B)Cotton seeds
C)Flax plant
D)Cotton flowers

Answer 1

Hint: Linen is an example of bast 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 answer:
Linen is a bast fibre which is found behind the bark in the stem of the flax plant. The flax plant is grown in the temperate and sub-tropical 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 to 6 inch and is around 12-16 micrometres in diameter. The fibres are 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 chis seeds. The cake of the seed is fed to the cattle after extracting oil. The cotton seed oil is used as a lubricant.

Cotton flowers- The cotton fibres are obtained from cotton flowers. The cotton fibre is used in making fabrics.

Hence, the correct answer is option (C)

Note: 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, paper for cigarettes, tea bags.
