Abstract

The effect of biopolishing treatment on color yield of cotton is of great importance to the dyers. Such treatment using cellulase has an influential role on dye ability of the fabric. Research into this area of dyeing has yielded apparently contradictory results. Cellulase treatment prior to dyeing can facilitate the dyeing process resulting in the higher color yield. However, zero impact or negative influence on the color yield of dyed fabric has also been reported. On the other hand, cellulase treatment after dyeing can be retarded by the presence of dye molecules or due to the interaction between dye molecules and cellulose. Though lots of research works have been done on bio polishing and as the application of the process in the textile industry has increased to a greater extent, the information on the effects of this process on color yield, both in cases of cellulase pre-treatment and posttreatment are absolutely necessary. Considering this the paper mainly focuses the previous works regarding the effects of cellulase action (Both before and after dyeing) on the color yield of dyed cotton.

Highlights

Biopolishing is a biological process in which the cellulase enzyme acts on the surface of the cellulosic materials
The author explained that if the weight loss observed due to cellulase treatment was not taken into account, there was a likelihood of observing an increase in K/S value for cellulase treated samples, as the amount of dye added per unit weight of fabric was increased
The authors explained that cellulase enzyme converts the cotton structure to a more accessible textile substrate which is much more amenable to the dye, beside its biopolishing effect which plays a key role in reflectance based measurements of the color on the fabric

Summary

Introduction

Biopolishing is a biological process in which the cellulase enzyme acts on the surface of the cellulosic materials. The effect of cellulase treatment on color yield of cotton is of great importance to the dyers in both cases. Though lots of research works have been done on biopolishing and as the application of the process in the textile industry has increased to a greater extent, the information on their effects on color yield, both in cases of cellulase pre-treatment and post-treatment are absolutely necessary.
