ABSTRACT:
The present invention is directed to a new cellulase composition for finishing of cellulose-containing textiles, especially cotton. The improved properties of the cellulase composition are based on an elevated content of CBHII cellobiohydrolase type component in an otherwise normal background cellulase composition. When the composition with elevated CBHII contents is used improved color properties, increased lightness, improved visual appearance and reduced pilling tendencies are achieved. The strength properties of the textile materials are essentially unchanged as compared to previously used cellulase compositions.
