내구유연발수제를 제조할 목적으로 전보에서 각각 합성한 poly(OMA-co-DAMA)[PODC], poly(DMA-co-DAMA)[PDDC], poly(EMA-co-DAMA)[PEDC] 각각의 양이온화물과 지방산 카르바미드의 양이온화물을, 왁스류 및 유화제들과 블렌드시켜 발수제 PODCW, PDDCW, PEDCW를 각각 제조하였다. 발수제 PODCW, PDOCW, PEDCW 각각을 나일론 태피터에 단독 및 수지병용으로 처리하여 내세탁성, 방추도, 인열강도 및 접촉각 등을 측정해 본 결과, 물성의 향상을 가져왔다. 그러나 발수도는 PODCW의 경우 90^- 정도로 사용가능하였으나, PDDCW화 PEDCW의 발수도는 저하되었다. 또한 발수제와 나일론 섬유와의 반응메카니즘을 추정하고 내세탁성 결과치를 검토한 결과 제조된 발수제가 내구성 발수제임을 입증하였으며, SEM으로 발수처리된 나일론 태피터의 표면구조를 관찰하였다.

Durable softening water-repellenting agent such as PODCW, PDDCW and PEDCW were prepared by blending cationized compounds such as poly(OMA-co-DAMA)[PODC], poly(DMA-co-DAMA)[PDDC] and poly (EMA-co-DAMA)[PEDC], and cationized compound of fatty carbamide, of which synthetic methods were reported in the previous paper, wakes, and emulsifiers. The results of washability, crease recovery, tearing strength and contact angle of the nylon taffeta treated with PODCW, PDDCW and PEDCW with and without textile finishing resin, showed a remarkable improvement of the physical properties. Rating of water repellency of nylon taffeta treated with PODCW was 90^-, but those treated with PDDCW and PEDCW were not high enough to use in industry. From the results of the searching of reaction mechanism of nylon fiber with water-repellenting agent and washability of the fiber treated with water-repellenting agents, the prepared water-repellenting agent proved to be durable. Surface structures of nylon taffeta treated with water-repellenting agent were examined by SEM.
