For this study, 18 kinds of cut and sew or seamless knitted test garment were made. Samples differed from each other by skirt angles(90°, 180°), gauges(7G, 12G, 15G), and grain directions(bias direction, wale direction, and radial direction). After measuring the mechanical properties of various gauges on the seamless knitting machine, I compared shape of the knitted flare skirt through subjective evaluation on appearances. The data analysis methods used in this study were descriptive statistics, one-way ANOVA, Duncan-test, correlation analysis, and regression analysis. The subjective evaluation on appearances of knitted flare skirts showed the following: In case of 90° skirt, the seamless skirt showed a much higher score in every gauge expect that of the cut and sew 12G, and silhouette of 15G wale direction. In case of the 180° skirt, the seamless type showed a much higher score in every item over the cut and sew expect the silhouette part of 7G wale direction.

본 연구는 Poly(ether block amide) (PEBA)와 poly(dimethyl-siloxane) (PDMS)를 혼합한 블렌드막(PEBA: PDMS = 5 : 2,6 : 1 wt%)을 상전이법을 이용하여 제조하여, 이산화탄소의 분리능을 향상시키고자 하였다. PDMS와 PEBA (4033) 은 투과특성의 비교를 위해 각각 같은 방법의 단일막으로 제조되었고, 용매로는 n-butanol을 사용하였다. 제조된 막은 SEM 을 이용하여 morphology를 분석하였고, 압력에 따른 CO2와 N2의 투과도를 측정하였다. 실험결과, PEBA/PDMS 블렌드막은 3기압에서 단일 PDMS막에 비해 N2에 대한 CO2의 선택도가 4~5배 높은 것으로 나타났다.
