A Study on the Preparation of Durable Softening Water-repellent by Blending Acrylic Copolymer and Fatty Carbamide - IV. Water-repellent Finish of P/C Blended Fabrics -

Durable softening water-repellenting agent such as PODCW, PDDCW and PEDCW were prepared by blending cationized compound such as poly(octadecyl methacrylate-co-2-diethylaminoethyl methacrylate)[PODC], poly(2-dodecyl methacrylate-co-2-diethyl-aminoethyl methacrylate)[PDDC] and poly(2-ethylhexyl methacrylate-co-2-diethyl-aminoethyl methacrylate)[PEDC], and cationized compound of fatty carbamide, of which synthetic methods were reported in the previous paper, waxes, and emulsifiers. The results of physical tests of the P/C blended fabrics treated with PODCW, PDDCW and PEDCW with and without textile finishing resin, showed a remarkable improvement of the physical properties. The prepared water-repellenting agents, PODCW-6 and PDDCW-1, were treated on P/C blended fabrics with and without resin. For any cases, there are a little changes between initial water repellency and repellency after 3 times washing of the fabrics. Therefore, the water-repellenting agents proved to be a durable agents, and initial water repellencies were 100+ and 90+ point, respectively.
