KETOPREP-LA

KETOPREP-LA | Low alkali all in one pretreatment product

Product Information

Ketoprep LA is a novel all-in-one product where we have to use less caustic during bleaching. Bleached fabric with Ketoprep LA exhibits very good whiteness index, soft fabric, absorbency and instant rewetting. Yarn bleached with Ketoprep LA decreases the coefficient of friction, improves strength and reduces hairiness to a certain extent. The application procedure does not require use of peroxide stabilizer.
