Studies on the Durable Softners (II) -Applications of Alkyl Imidazoline Derivatives as the Durable Softners-

내구성유연제에 관한 연구 (II) -알킬이미다졸린 유도체의 내구성유연제로서의 응용-

Softners-BHICS, BBICS, and BTICS were prepared from 1, 2-disubstituted imidazoline compounds, such as 1-behenoylaminoethyl-1-glycidyl-2-heneicosylimidazolinium chloride(BHIC), 1-behenoylbis(aminoethyl)-1-glycidyl-2-heneicosylimidazolinium chloride (BBIC), and 1-behenoyltris(aminoethyl)-1-glycidyl-2-heneicosylimidazolinium chloride(BTIC), and treated to acrylic fiber. The measurements of softness, lubricating and antistatic properties showed that they have not only good softness and lubricating property but also a little antistatic property. Furthermore, the initial bending resistance for BBICS and BTICS was 5 grade, and remained 3~4 grade after 5 times washing. As results of these tests, they showed good softner effects having durability. The prepared softners were proved to be durable softner through a series of experimental results for washable properties of feeling by varying treating temperature and pH change.

1, 2-Disubstituted imidazoline 화합물인 1-behenoylaminoethyl-1-glycidyl-2-heneicosylimidazolinium chloride(BHIC), 1-behen oylbis(aminoethyl)-1-glycidyl-2-heneicosylimidazolinium chloride(BBIC) 및 1-behenoyltris(aminoethyl)-1-glycidyl-2-heneicosylimidazolinium chloride(BTIC)로부터 유연제 원액인 BHICS, BBICS, BTICS를 각각 제조하여 아크릴섬유에 유연처리를 한 후 유연성, 평활성 및 대전방지성을 측정한 결과 유연제 모두 유연성과 평활성이 양호하였으며 약간의 대전방지성도 보유하였다. 또한 BBICS와 BTICS의 초기강연도는 5 grade, 5회 세탁후는 3~4 grade로 각각 나타나 내수성을 지닌 양호한 유연효과를 나타내었다. 아울러 처리온도에 따른 촉감의 내세탁성 및 pH 변화에 따른 촉감의 내세탁성 시험결과 등을 통하여 제조된 유연제가 내구성 유연제임을 입증하였다.
