ABSTRACT:
Compositions suitable for use as hot-melt textile warp sizes are prepared by blending copolymers of ethylene and acrylic acid, methacrylic acid and the like, with selected low-molecular-weight additives, such as low-molecular-weight ethylene/acrylic acid copolymers, ethylene/methacrylic acid copolymers, and/or dicarboxylic acids, monoglycerides and waxes. These blends have low melt viscosities, can be readily applied to textile yarns with conventional hot-melt application equipment and set up rapidly to nontacky protective coatings on the yarns. After processing of the yarns, the new hot-melt sizes are readily removable using conventional securing procedures.
