AcademicChemistryNCERTClass 6

Fabric of cotton saree is made by weaving cotton yarn which in turn is made by spinning thin cotton fibres. 

The following steps are involved in the preparation of fabrics:
  1. Obtaining fibre: Extraction of the fibre from its source (Plant or Animal)
  2. Preparation of yarn from fibres by spinning: A group of fibres extracted are twisted together (by the process of spinning) to form Yarn.
  3. When two sets of yarn are involved, yarns are woven on looms to make a fabric. When a single yam is used, the fabric is prepared by knitting: These yarns are twisted tightly and allowed to rotate on the different types of rollers, weaved and knitted to produce Fabrics.
  4. The fabrics produced are dyed: These fabrics are treated with chemicals in the textile industries to make different types of clothing materials. Later these are processed for bleaching to give a smooth, shiny look, colour dying to add colours and design the fabrics.

Hence to summarize the steps we can write:
