KETOPREP-LA (CONC)

KETOPREP-LA (CONC) | Low alkali all in one pretreatment product

Product Information

Ketoprep-LA (Conc) is a novel, all in one pretreatment product. It is a biodegradable product and require low alkali during bleaching of cellulosic substrate. Bleaching with Ketoprep-LA (Conc) 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 (Conc) decreases the coefficient of friction, improves strength and reduces hairiness to a certain extent.
