Abstract

This study is aim to standardize the process parameter is desizing, scouring and bleaching and come out with the best practice in chemical consumption in pretreatment of terry towel. The determination of the pretreatment performance because of desizing, scouring and bleaching chemical concentration.

The careful consideration of process parameter in pretreatment helps the wet processing industry to ensure the application of standard concentration of the chemical during processing. The concentration of alkali use in the pretreatment of cotton is represented by many researches.

In this process by varying the chemical concentration, time and temperature, we obtain good result. This particular research on the reduction of the total chemical consumptions, time and temperature. The results were found to promising and comparable to that conventional pretreatment fabric which is performing in terry towel industry.

The aim of this project work is to develop less consumption of chemical pretreatment method which can produce similar desizing efficiency, whiteness index, and absorbency of the fabric. In this study we found reduction of pollution load associated with excessive usage of chemical in standard conventional pretreatment process.

It was found that with the reduction of caustic, stabilizer and Hydrogen Peroxide concentration performance of pretreatment become better. Effect of the above process by reducing chemical consumptions in desizing scouring, bleaching (pretreatment) of terry towel fabric in soft-flow Thies machine which gives good results and better absorbency, bleaching efficiency and whiteness index of bleached fabric which have been studied in this work.
