이 연구는 감성의류용 형상기억 메모리직물의 제조 방법과 물성을 조사하기 위해 저온열처리와 정장열처리 가연법을 폴리프로필렌 POY와 SDY에 각각 적용하고 이들 사를 사용하여 PP형상기억메모리 직물을 air-jet직기에서 제조하였다. 물성비교를 위해서 PET와 PTT형상기억메모리 직물도 같이 제직하여 4가지 형상기억 메모리 직물시료를 만들고 이들의 여러 가지 물성을 측정 비료분석하여 다음과 같은 결론을 얻었다. PP형상기억 메모리 직물에 사용하기 위해 저온가연법과 정장열처리법에 의해 만든 PP가연사의 물성은 절단강 신도가제직성에 문제가 없는 값을 가졌으며 특히 열수축율이 습열은 1.5% 이하 건열은 3~5% 범위를 가짐으로써 PTT의 5~8%의 높은 열수축율에 비해 열적 안정성을 가졌다. PP형상기억 메모리 소재의 변형된 형태를 유지하는 소성적 성능 특성 평가법인 Toray 방추성 평가는 PP소재가 PTT와 같은 5급을 나타냄으로써 우수한 변형 유지특성을 보였다. 또한 PP형상기억 메모리소재의 보온성은 PTT소재보다 약 56% 향상된 결과를 보였으며 스프레이법에 의한 발수성은 PTT소재에 발수처리한 소재와 동일하게 5급의 우수한 발수성을 보였다. 그리고 PP형상기억 메모리소재의 형상기억 특성을 평가 할 목적으로 3D 이미지 방법과 카메라 측정결과 PTT소재와 비슷한 형상기억 특성을 보임을 확인 할 수 있었다.

This study was to investigated physical properties of lining fabric (Nylon, Acetate, Rayon and Polyester) such as shrinkage, tensile strength, moisture regain and crease resistance. The results were as follows. 1. The number of repeated washing times and the concentration of the detergent almost didn't affect on the change of tensile strength. 2. As washing increase more, the shrinkage of all sample was more increased. In the case of Rayon, it was showed that shrinkage was high by $1{\sim}3$ times washing. In the case of Nylon, it was showed minus shrinkage according to frequency of washing. 3. The moisture regain was very decreased by 1 times washing. But the moisture regain was increased with increase in frequency of washing and resulted in it was showed a similar value with controls. 4. As the frequency of washing and the concentration of detergent increase more, the crease resistance was decreased considerably because the elasticity of fiber decreased by mechanical force such as tension, bending and pressure and alkali.

The micro structure of POY was modified and a wool-like touch yarn of composite fibers with different shrinkage was made. With this yarn 12 different fabrics with wool like touch were prepared. The characteristic physical property changes of the fabrics examined are as follows: 1. In all cases, the initial high shrinkage stages were observed in hot water treatment and the 3D images of complex multilayer of typical doubling fibers with different shrinkage were also observed in hot air treatment of 170C. 2. The tensile strength changes of satin and plain fabrics with the change of twist count showed similar behavior. However, WT's were slightly higher and RT's was lower in twill and satin fabrics than those in plain fabric. 3. Since a slight decrease of B's of twill fabric found with increasing twist count under given experimental condition, it could be influenced on the anti-drape stiffness was decreased and flexibility was increased. 4. A significant decrease of G values was observed in the twist count 800-1000 T.P.M However, in the twist count higher than 1000 T.P.M G values observed were kept nearly constant. 5. MIU of plain and twill fabrics showed a drastic decrease at the twist count higher than 1000 T.P.M.

This study focuses on the optimal washing conditions for dry cleaning recommended fabrics to minimize dimensional changes using wet cleaning. We suggest water-based alternatives to a perchloroethylene based cleaning process. Wool and rayon fabrics were laundered under various washing conditions and then air-dried for 24hrs. All specimens were extended after spinning and shrunk after drying. This is probably because the fibers were swollen and extended by wetting. The wool fabrics were shown to be acutely influenced by washing temperature and mechanical force. The optimal washing conditions for wool fabric to minimize the dimensional change implied a normal washing temperature and minimized mechanical force. For rayon specimens, dimensional change by a hand wash showed a remarkable decrease compared with a machine wash. Rayon fabric seemed to be influenced by the quantity of water contained in the fabric after spinning and washing time. Therefore, the desirable washing conditions for rayon fabric are to reduce the time required for washing and to increase the spin speed.

Shrink resist finishing of wool fabric was carried out with Monoethanol aminesulphite (MONAMIN BTN) shrink resist agent after chlorination with Dichloro isocyanuric acid (DCCA). The purpose of this study is to investigate the effect of treating conditions, such as concentrations of DCCA and MONAMIN BTN, pH of treating bath, dyeing times, curing times and temperatures, on dyeing property of wool fabrics. K/S values and fastness properties of dyed wool fabrics were measured. The K/S values of dyed fabrics were increased gradually with increasing concentration, and decreased with increasing curing time. The optimum dyeing time and curing temperature were 60 min and $140^{\circ}C$, respectively. Also it seems likely that the shrink resist finishing carried out at 3% (o.w.f.) of MONAMIN BTN and pH 7 of resin treating bath is effective in increasing K/S values. Light fastness of fabric dyed was very poor and the fastness of fabric dyed was not influenced by the treatment conditions.

In this study, the appearance change and the heat moisture transfer properties of knitted fabric by yarn shrinkage were examined to obtain useful data on the development of thermo-sensitive functional materials. Eleven types of knitted fabric were knitted using highly bulky acrylic-blended yarn. After shrinking the specimens using dry heat treatment, the appearance change and thickness were measured. An HEC simulator was adopted for measuring the heat moisture transfer properties of specimens by yarn shrinkage. When holes were arranged vertically in the mesh structure, the specimens with 2,500 and 5,000 holes showed high percent change of hole area, appearance, and thickness. When holes were diagonally arranged in the mesh structure, the percent change of hole area in the specimen with 1,250 holes was larger than the one with 2,500 holes. However, the dimensional stability of the specimen with 2,500 holes was better because of its smaller appearance and thickness change. In the tuck structure, the percent change of hole area in the specimen with 625 and 416 holes was relatively large compared with the appearance and thickness change. Furthermore, the hole size in the tuck structure was smaller than that in the mesh structure but the percent change of hole area was larger. Therefore, it was proved that the tuck structure is more suitable than the mesh structure for developing thermo-sensitive functional materials. Heat moisture transfer property test verified that the change of hole area by yarn shrinkage enabled obtaining the thermal effect due to the distinct temperature difference in the inner layer.

The dimensional properties on polyester warp knitted fabrics with various lengths of underlap were studied. The results indicated that loop density increased with decreasing loop length and loop density of satin warp knitted fabric are a little higher than that of reverse satin warp knitted fabrics at a constant loop length. As the distance of underlap becomes shorter, the weight per unit area and thickness increases, the bulkiness decreases and the shrinkage of knitted fabrics become larger toward wale in satin warp knitted fabric and toward the course in reverse satin warp knitted fabric.

In this study, wool/nylon(50/50%) blend yarn and its fabrics for tra-biz(complex word of travel+business) garment were prepared, and its wear comfort characteristics were investigated through thermal manikin and human-body wearing experiment. In addition, tactile wearing performance from fabric mechanical properties and the dimensional stability and the pilling of the fabric specimen during wearing and dry-cleaning were measured and compared with those of wool 100% fabric specimen. Heat keepability of the wool/nylon(50/50%) blend fabric by thermal manikin experiment was superior than that of wool 100% fabric, this result was verified with human-body wearing experiment and its result coincided well with this experimental result. Tactile wearing performance of the wool/nylon(50/50%) fabric from fabric mechanical properties measured by FAST system was better than that of the wool 100% fabric. The dimensional stability of the wool/nylon(50/50%) fabric was more stable than that of the wool 100% fabric. Because relaxation shrinkage was lower and hygral expansion of wool 100% fabric was more high. However, the breathability and pilling property of the wool/nylon(50/50%) fabric were inferior than those of the wool 100% fabric. The possibility of application for tra-biz garment of wool/nylon(50/50%) blend fabric was observed because of good heat keepability, tactile wearing performance and washing fastness.
