본 연구는 섬유유연제 선택기준으로 중요하다고 인식하고 있는 향에 대한 주관적 선호도와 감성구조를 분석하였다. 이를 위해서 서로 다른 향을 가진 섬유유연제 12종을 선정하여 일차적으로 선호도를 3단계로 평가하도록 하였고, 각 단계별로 빈도가 가장 많은 향을 2종씩 골라서 최종 6종의 향(후리지아, 블루비앙카, 바이올렛, 허브, 그린티, 피치)이 함유된 섬유유연제를 선정하여 남녀 대학생을 대상으로 주관적 선호도를 조사하였다. 주관적 선호도에서 가장 선호된 향과 가장 선호하지 않은 향 두 종류에 대해서 감성을 평가시켰다. 그 결과 가장 선호하는 섬유유연제 향은 후리지아 향이었고 피치 향은 가장 선호하지 않는 향이었는데, 선호하는 향의 순서와 선호도는 성별에 따라 부분적으로 유의한 차이를 보였다. 또한 후리지아 향과 피치 향의 감성구조는 다르게 평가되었다.

Organic acid salt of fatty polyamide (DDDT) and acrylate of fatty carbamide (DDTCA) were synthesized as a main component for the softener. O/W type non-ionic softener (NSC) was prepared by blending DDDT and DDTCA with beef tallow, lanolin anhydride. polyoxyethylene(7) stearyl ether, and polyoxyethylene(50) oleyl ether. After treatment of NSC to all cotton fabrics, the physical properties such as tear strength, crease recovery, and flexing abrasion resistance were measured. As a result of the measurement, NSC was proved to be durable non-ionic softener with good softness.

In order to prepare a softener, alkyl imidazoline salt, fatty carbamide salt, and fatty polyamide salt were synthesized first, and then the synthesized salts were blended. The prepared softeners were applied to acrylic fibers, and then several properties were tested. As a result, the prepared softeners show good softening and lubricating properties, and they also show a little antistatic property. Through bending resistance tests and measurements of feeling change of acrylic fibers treated with the softeners, it was proved that the prepared softeners are durable softeners.

Fatty polyamide that gives softness, lubrication and bulky property and alkyl imidazoline that gives durable softness and antistatic property were synthesized. then, an O/W-type durable softener (DSN) was prepared by the emulsion of the synthesized fatty polyamide and alkyl imidazoline. Emulsion stability of the DSN was good, and the mixed HLB value was 11.2. From the measurement of softness, lubrication, antistatic property, bending resistance, and color fastness, it was proved that the prepared DSN was a good durable softener for nylon.

To prepare a O/W type durable softner(OESA), octadecamidoethylaminoethyl dodecate and tetra (2-dodecamidoethyl) urea synthesized as the main components of softner, were blended with polyoxyethylene(20) oleyl ether, sorbitan sesquioleate, and polyoxyethylene(7) stearyl ether in various compositions. Emulsion stability of OESA was good, and mixed HLB value was 9.7, OESA was found was to be good durable softner for nylon through the examination of softness, lubriation, antistatic property, bending resistance, and color fastness.
