Effects of Time on the-scouring & Bleaching Process of Cotton Knitted Fabrics

Abstract

This study pretends to assess the eco-friendly Bio-scouring and bleaching process on cotton knitted fabrics. Living organisms and their components are being used to remove natural and added impurities from cotton fabric in Enzymatic scouring or Bio-scouring application. This project is mainly focused on, effects of different periods of time (30mins, 45mins and 60mins) on the Bio Scouring and bleaching process of cotton knitted fabrics and aim of the work was to measure fabric characteristics (CPI, WPI, SL, GSM), absorbency test (Immersion test, Drop test, Wicking test) as well as PH test. For doing the project we took three types of fabric like Single Jersey, (1*1) Rib and Plain Interlock. We studied the Bioscouring & bleaching process of cotton by using pectinase enzymes. Here for doing Bioscouring& bleaching we changed the time (30 mins, 45 mins, 60 mins). We took pectinase, emulsion and wetting agent. After we had done the process, we tested the fabric like absorbency test, wicking test and drop test. Stitch length, WPI, CPI, GSM and weight loss of fabric test also. After done the research we found that Single Jersey, (1*1) Rib and Plain Interlock were showing higher% of change in CPI, WPI, SL, GSM, Weight Loss and good Absorbency in 60mins of Bio-scouring and bleaching process.
