A Study on the Preparation of Durable Softening Water Repellents by Blends of Fatty Carbamide/Wax/Acrylic Copolymer(IV);Water Repelling Treatment of P/C Blended Fabrics

지방산 카르바미드/왁스/아크릴 공중합체의 블렌드에 의한 내구유연발수제의 제조에 관한 연구 (IV);P/C 혼방직물에의 발수처리

To prepare a durable softening water repellent, quaternized octadecyl methacrylate-2-diethyl-aminoethyl methacrylate as a mother resin and quaternized 1, 3-dioctadecyl-2, 7-dioxy-6, 8-di(2-hydroxyethyl)-1, 3, 6, 8-tetraazacyclodecane which increase the softening effect and the hydrostatic pressure blended with waxes and their emulsifier in various proportions to give water repellent PADWC. As the results of the measurement of water repellency, washable, tear strength and crease recovery to polyestercotton(P/C) blended fabrics treated with PADWC only or addition of textile finishing resin, the physical properties were increased. There was no significant lowering effect in water repellency when PADWC was treated the antistatic agent by the one-bath method, and the effect of water repellency by the adding the catalyst was studied. PADWC was confirmed as durable water repellent with the results of making little difference of water repellency as ${\pm}5$ point after and before washing.
