Fibre to Fabric Test - 5

Hemp is a vegetable fibre.

Soil that is well drained, nitrogen-rich and has abundant organic matter is best for its cultivation.
It is a harsh and strong fibre and is more durable than cotton.

The Nylon riots were a series of disturbances at American stores created by a nylon stocking shortage.

Nylon is a fully synthetic fibre and it belongs to the category of polyamides.
Hence, the statement 'b' is incorrect.

The statements 'a' and 'c' are correct and nylon has a greater tensile strength than polyester.
It has a low water absorbency and is easy to dry. It is also resistant to abrasion

Wool is an animal fibre obtained from the fur of animals like sheep, goat, rabbit, deer, etc.

Cotton grows well in the soil that can retain water. So, Black soil is perfect for the growth of cotton plants as it can retain water. Cotton seeds require warm tropical climate to germinate. Without adequate sunlight cotton plants cannot grow.

Cotton and jute are fibres obtained from plants, whereas silk and wool are fibres that are obtained from animals.

Cotton is the most common fibre and is obtained from the seeds of the cotton plant and is also called a seed fibre.

Jute, hemp and flax are bast fibres.

Cotton burns with a steady flame and smells like burning leaves. The ash particles left from burning are unburnt carbon particles.
Nylon and polyester melt and recede rapidly from the flame.

Wool and silk burn with a smell of hair burning.
Hence, all the observations are correct.

Rayon is a semi-synthetic fibre obtained by the chemical treatment of wood pulp.
