BASE SUBSTANCE OF CATIONIC FABRIC SIZE, ITS PRODUCTION AND LIQUID FABRIC SIZE COMPOSITION CONTAINING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a cationic fabric size base substance high in adhesive property to a blended fiber e.g. polyester-blended fiber and capable of providing its good finishing property. SOLUTION: This cationic fabric size base substance is obtained by polymerizing 100 pts.wt. of a lower fatty acid vinyl ester, 20 to 40 pts.wt. of an unsaturated carboxylic acid and 130 to 300 pts.wt. of an unsaturated carboxylic acid alkyl ester in an aqueous solvent, in the coexistence of one or more cationic monomers and/or cationic polymer and in the presence of cationic polymer emulsion particles obtained by emulsion-polymerizing a lower fatty acid vinyl ester, thus obtaining the base substance where a cationic polymer emulsion is formed.
