KETOPREP-LA

Ketoprep-LA | Low Alkali All in One Pretreatment Product

Product Information

Ketoprep-LA is a novel, all in one pretreatment product. It is a biodegradable product and requires low alkali during bleaching of cellulosic substrate. Bleaching with Ketoprep-LA exhibits very good softness, absorbency, rewetting and whiteness than the conventional bleached fabric. Bleached fabrics confer low strength loss and weight loss as a concentration of alkali used in bleaching is low. Yarn bleached with Ketoprep-LA decreases the coefficient of friction, improves strength and reduces hariness to a certain extent.
