1. Pashmina is a fine, fluffy, light and warm wool from Kashmir and nearby Himalayan areas. Pashmina is obtained from the underfur of Cashmere goat.

2. The process by which selected curly wool fibres are straightened by passing through rollers is called carding.

3. When the caterpillar is ready (in 5-6 weeks) to enter the pupal stage, it stops feeding and its salivary gland starts secreting a sticky fluid (a protein called fibroin). This fluid hardens on exposure to air and forms a long thread of silk.

4. The silk filaments are separated from the cocoons. This process is called reeling of the silk. The resulting fibre is known as raw silk. It can be dyed in various colours.

5. The larvae that are hatched out are called caterpillars. Caterpillars feed themselves on the freshly cut mulberry leaves and grow fast.

7. The process of removing hair (or cutting off hair) from the body of a sheep in the form of fleece is called shearing.

8. Female silk moth lays hundreds of eggs on the mulberry leaves. The larvae that are hatched out are called caterpillars. Caterpillars feed themselves on the freshly cut mulberry leaves and grow fast.
