Title:
POLYVINYL ACETATE EMULSION AND TEXTILE SIZE HAVING ANTIREDEPOSITION EFFECT
Document Type and Number:
Japanese Patent JP3618484
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a polyvinyl acetate emulsion which has a long-term viscosity stability, good low-temperature film-forming properties even when not plasticized, forms a coating film having a high hardness and an excellent heat resistance, and prevents soil redeposition when used as a textile size.
SOLUTION: This emulsion is obtained by emulsion-copolymerizing 100 pts.wt. mixture comprising 99.5-90wt.%, based on the entire mixture, vinyl acetate and 0.5-10wt.% carboxylic monomer in the presence of 30-200 pts.wt. modified starch mixture comprising 10-90wt.%, based on the entire modified starch mixture, modified starch having a viscosity of 1-1,000cP as measured in the 10% aqueous solution thereof at 50°C and 10-90wt.% saccharified starch having a viscosity of 3-300cP as measured in the 50% aqueous solution thereof at 50°C.
