Abstract
A size for textile fiber which comprises a modified polyvinyl alcohol type resin obtainable by the alkali saponification of a copolymer comprising a vinyl ester and an ethylenically unsaturated dicarboxylic acid substantially free from the monoester, diester and anhydride as essential and predominant copolymeric units. The size has excellent adhesive and cohesive strengths with respect to textile fibers as well as superior desizing properties and workability.
