[Extra information:
Silk fibres are natural animal fibres obtained from the cocoon of silkworms. Silk threads (or yarn) are made by twisting together long fibres (called filaments) of silk.  Its fabric is very smooth to touch and has vibrant colour and shine. 
Jute is a natural plant fibre. It is a long, soft, shiny plant fibre that can be spun into coarse strong threads. It is obtained from the stems of jute plants (Corchorus). In India, jute is mainly grown in areas of West Bengal, Bihar, Assam and Andhra Pradesh.
The process of extraction of jute fibres from the jute plant is given below:
- The fibres are first extracted by retting. The retting process consists of bundling jute stems together and immersing them in slow-running water.
- There are two types of retting: stem and ribbon.
- After the retting process, stripping begins; women and children usually do this job. In the stripping process, non-fibrous matter is scraped off, then the workers dig in and grab the fibres from within the jute stem. These fibres are used to make further products.]
