POLY(VINYL ALCOHOL) POLYMER BLEND TEXTILE SIZES WITH IMPROVED ABILITY TO BE DESIZED

摘要

Compositions based on blends of certain specified poly(vinyl alcohol) copolymers and other poly(vinyl alcohol) polymers are described which are useful as sizes, and have improved ability to be desized from fabrics compared with the other poly(vinyl alcohol) polymers alone. The specific poly(vinyl alcohol) copolymers useful in the blends with other poly(vinyl alcohol) polymers are copolymers having a high level of acrylic ester comonomer. The blend sizes are useful in producing woven materials since they are excellent sizes, and are uniquely adaptable to caustic desizing.
