Abstract
Compositions based on blends of certain specified poly(vinyl alcohol) copolymers and various starches are described which are useful as sizes, and can have improved ability to be desized from fabrics compared with the starches alone. The specific poly(vinyl alcohol) copolymers useful in the blends with the starches 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.
