The document summarizes the scouring process used in textile manufacturing. Scouring involves removing natural and added impurities from textiles using chemicals like caustic soda and detergents to produce a clean and hydrophilic material. The objectives of scouring are to make the fabric highly absorbent, remove oils, waxes and other impurities, and prepare the textile for downstream processing. Scouring can be carried out via continuous processes like the J-Box or discontinuous batch processes using a Kier boiler. The effectiveness of scouring is assessed through tests like drop, immersion and spot tests.

- 3. SCOURING A Scouring: Scouring is the process by which all natural and additive impurities such as oil, wax, fat, hand dust etc. are removed to produce hydrophilic and clean textile material. It is one of the vital processes of wet processing B C
- 4. SCOURING A Scouring: Scouring is the process by which all natural and additive impurities such as oil, wax, fat, hand dust etc. are removed to produce hydrophilic and clean textile material. It is one of the vital processes of wet processing B Objects of Scouring: 1) To make the fabric highly hydrophilic. 2) To remove impurities such as oils, waxes, gum, husks as nearly as possible. 3) To increase absorbency of fabric or textile materials without physical and chemical damage. 4) To produce a clean material by adding alkali. 5) To make the fabric ready for next process. 6) To remove non-cellulosic substance in case of cotton.

CScouring process depends on: The type of cotton. The color of cotton. The cleanliness of cotton. The twist and count of the yarn. The construction of the fabric. The shade % and type of shade of finished product.
