Ketoprep-LA Pretreatment Solution Manufacturer

PRODUCT LITERATURE

KETOPREP-LA

Product Information

Ketoprep-LA 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 exhibits very good softness, absorbency, rewetting and whiteness than the conventional bleached fabric. Bleached fabrics confers low strength loss and weight loss as 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.
