아크릴 공중합체와 지방산 카르바미드의 블렌딩에 의한 내구유연발수제의 제조에 관한 연구 - Ⅲ . 나일론 직물에의 발수가공 -
김영근,박창환,박홍수 ( Young Keun Kim,Chang Hwan Park,Hong Soo Park ) 한국공업화학회 1995 공업화학 Vol.6 No.1
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.

Myristyl 지방족기를 함유하는 제4급 암모늄염에 의한 PET 섬유의 감량가공 효과
박창환,근장현,김영근,박홍수 ( Chang Hwan Park,Jang Hyoun Keun,Young Geun Kim,Hong Soo Park ) 한국유화학회 1994 한국응용과학기술학회지 Vol.11 No.2
MDABM and MDAEW, as a accelerating weight loss agents, were prepared by adding water to myristyldimethylbenzylammonium bromide(MDAB) and myristyldmethylethylammonium ethyl sulfate(MDAE) synthesized. As a result of weight loss finishing of the MDABW and MDAEW with NaOH on PET fiber, the ratio of weight loss of MDABW was very larger than that of MDAEW. This result showed that quaternary ammonium bromide had higher weight loss effect than quaternary ammonium sulfate, and the ratio of weight loss was greatly varied with the kind of quaternary ammonium salts used. In these conditions, proper treatment concentration, treatment time, and treatment bath ration were about 8g/l, 60~90min, and 40:1~50:1, respectively.

Permanent Press 가공용 실리콘 유연제의 합성과 그의 특성화
박창환,김승진,김영근,박홍수 ( Chang Hwan Park,Seung Jin Kim,Young Geun Kim,Hong Soo Park ) 한국유화학회 1995 한국응용과학기술학회지 Vol.12 No.1
Silicone softner(SSN-3) for permanent press(PP) finish was prepared by blending beef tallow hardened oil for improving softness, water, the emulsion, which was synthesized from pentaerythritol monostearate as a softening component and silicone oil KF-96 as a lubricating component. The prepared SSN-3 and the PP finishing resin were applied to PP finishing cotton broad cloth and P/C gingham samples using one bath method. The properties such as crease recovery, tear strength, bending resistance test were tested. The samples treated with SSN-3 and PP finishing resin have improved properties, compared with nontreated samples, those treated only with PP finishing resin, those treated with commercial PP finishing softners and PP finishing resin. Also from the bending resistance test, the two kinds of fabric samples treated with SSN-3 of 3% showed grade 5 and these were good enough in feeling.
