摘要：
Durable press fabrics possessing the improved ability to absorb optical brighteners during laundering have been prepared. Repeated launderings with detergents which contain these optical brighteners increase the whiteness with each laundering. This quality is imparted to cotton and other cellulosic fabrics when polyvinylpyrrolidone is incorporated in a crosslinking formulation.
