Abstract

This paper shows the effect of different bleaching agent on whiteness index and bursting strength of the cotton knitted fabric. Bleaching process uses three types of bleaching agents namely hydrogen peroxide (H2O2), sodium hypochlorite (NaOCl) and calcium hypochlorite Ca(OCl)2 with varying their concentration and these are 1.5 g/l, 2.5 g/l, 3.5 g/l, 4.5 g/l, and 5.5 g/l. In the same time, scouring agent was caustic soda, and its concentration for all the bleaching agents was same. It is obvious that with the increase of bleaching agent concentration, whiteness index increases, and bursting strength reduces.

Highlights

This paper shows the effect of different bleaching on hydrophilicity and whiteness index shows that with agent on whiteness index and bursting strength of the cotton the increase of hydrogen peroxide and activator
Different bleaching agents at different peroxide, which is from glucose oxidase enzyme, shows concentration were used in this research paper for lower whiteness values than the expectation of the investigation of whiteness index and bursting strength of commercial processes [4]
Whiteness index of the scoured and bleached sample was determined by the reflectance value of a) Effect of hydrogen peroxide (H202)on whiteness spectrophotometer (Datacolor650) at 100 observer and

Summary

↓ Result and Discussion

Saravanan et al study on the bleaching effect c) Scouring & Bleaching Recipe of cotton fabrics shows that by using hydrogen. Different bleaching agents at different peroxide, which is from glucose oxidase enzyme, shows concentration were used in this research paper for lower whiteness values than the expectation of the investigation of whiteness index and bursting strength of commercial processes [4].
