In this research, consumer awareness investigation and wearing test were carried out for obtaining useful data on the development of thermo-sensitive functional clothing material. A survey involved 216 people in Seoul and Kyeonggi- do, and 200 questionnaires data were analyzed by descriptive statistics and frequency using SPSS 17.0. Four healthy men in twenties were participated for wearing test. Subjects in normal loungewear were exposed to temperature change from the initial temperature 30oC down to 5oC for an hour in a climate chamber. The environmental temperature, surface temperature of garment and skin were measured. As a result, most of respondents have all season clothing products such as underwear, hosiery, and jogging suit for loungewear. Also, thermo regulator y functional clothes are frequently used as underwear and sweat shirt. The consumer awareness investigation on thermo regulatory functional clothing showed that the most important key buying factor is quick climate temperature response, easy maintenance, design and cost, in that order. Surface temperature of garment went down with the cooling down of environmental temperature. The lower environmental temperature, the greater temperature difference by body part showed. Skin temperature change by environmental temperature showed similar tendency of garment surface temperature. In comparison between garment surface and body skin, temperature difference became larger under the lower environmental temperature.

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.

This paper describes the first part of a study for obtaining useful data on the development of compression garments with high stretch knitted materials. Twenty types of compression garments sold in the domestic market were analyzed in terms of the knitting method and knit structure. After classifying these garment types into three elements of knit structure, a comparative analysis of the body part to which knit structure is applied was performed. Given the superior comfort of its finished product and seamless process productivity, the weft knitting technique was used more commonly than the warp knitting technique. All extracted knit structures were single-faced, and float and tuck were variously applied based on plain stitch. Plain stitch was applied on smooth body part surfaces, which do not require much compression. In the case of body parts that easily accumulate mass, such as the lower abdomen and sides, plain with float stitch was used by employing a mock rib structure to exert appropriate pressure on body and ensure a good fit. However, on body parts requiring a strong fit and pressure along with protection, plain with float stitch was used. Meanwhile, the structure in which float and tuck were combined based on plain stitch was applied for body parts with active muscles.

This study measured dyeing properties under different dyeing conditions and levels of antimicrobial activity when man-made fibers are dyed with gallnut, including rayon, tencel, tencel blended fabric, soybean fiber, and nylon non-mordanted. The dye up-take (K/S), color ($L^*a^*b^*$), and color differences (${\Delta}E$) were measured with a colorimeter, and the number of bacteria present in the dyed fabrics were determined using Staphylococcus aureus and Klebsiella pneumonia as strains. The results are as follows: First, the optimal dyeing conditions for man-made fibers dyed with gallnut are 60 minutes of dyeing time and a $80^{\circ}C$ dyeing temperature. Second, gallnut dye is most effective on soybean fiber and then, in descending order of effectiveness, on nylon, rayon, tencel, and tencel blended fabric. This means that dyeing properties of nitrogen containing fibers are excellent when using gallnut. Third, all man-made fibers are dyed brown with gallnut. This implies dyeing possibility of man-made fibers about gallnut dye, so development and supply of natural dyed goods of man-made fibers can be increased. Fourth, in all man-made fibers dyed with gallnut extract, both Staphylococcus aureus and Klebsiella pneumonia show 99.9% reduction ratios of fungistasis, which indicate antimicrobial activity. Therefore, safe, functional, man-made materials can be developed to relieve symptoms from and treat patients with skin ailments.

A study on compressive garments guarantee the required pressure and form depending on the type of disease and the state of injury can be used in the preventive treatment of cardiovascular disease. This research is to provide a preliminary data to develop medical clothing products, especially knitted compression garments. Starling from analyzing knitted structure of imported pressure goods to apply to test samples, 11 kinds of knitted stretchy fabrics were manufactured under the various knitting conditions, then their tensile, mechanical and hand properties were measured. In comparison size changes by knitting structure, luck stitch applied structure showed an increase in course direction and decrease in wale direction. Float stitch applied structure indicated the contraction of size in width because of unformed loops and floated yam on the technical back of fabric. As a result of tensile properties in tuck and float applied structure, tensile strength was increased in the course direction. On the other hand, the more loops overlapped due to the tuck and float stitch, the more decreased their elongation and elastic recovery were. In case of mechanical properties, as the tuck and float stitch were overlapped double or triple the bending and shearing properties were risen. Accordingly, the drape of fabric becomes stiff, and its surface becomes rough and uneven. The measurements of hand properties showed that the value of KOSHI, FUKURAMI NUMERI in tuck and float applied structure are higher than the plain structure. This results from the relationship between the mechanical and hand properties.

온도 또는 pH 변화와 같은 외부자극에 의해 형상이 수축 또는 팽창될 수 있는 형상기억고분자는 약물전달체와 같은 의공학분야와 스마트섬유와 같은 의류산업 분야에서 핵심적인 역할을 하는 중요한 소재이다. 본 연구에서는 실생활에 적용가능한 온도에서 팽창하거나 수축하는 형상기억고분자 섬유에 대한 기초연구로서 섭씨 4도에서 융점을 보유하는 폴리에틸렌글리콜(PEG400)을 분자구조 내에 도입하여 저온에서 형상기억 특성을 보유한 소재를 구현하고자 하였다. 이를 위해 먼저 PEG400이 그래프트된 폴리실세스퀴옥산을 합성하고 이를 양말단이 디이소이아네이트기이고 PEG400 반복구조를 보유한 선형폴리우레탄고분자와 가교반응시켜 네트워크 고분자를 제조하고 특성을 분석하였다. 결과적인 네트워크 구조 고분자의 형상기억특성을 동적-기계적으로 분석한 결과 PEG400의 융점에서 네트워크 고분자의 유리전이가 발생하고 변형된 형상이 원래의 형상으로 회복되는 것을 확인하였다. Shape memory polymers that can be contracted or expanded on external environmental stimulus such as temperature or pH variation have been one of the most important materials for biomedical or smart fiber applications. In this study, we prepared polymers that presented shape memory characteristics at a low temperature by introducing a poly(ethylene glycol) (PEG400) with a melting temperature of 4 ℃ into the structure units of the polymers. We first synthesized polyhedral oligomeric silsesquioxane (POSS) grafted with PEG400, followed by cross-linking reaction with a linear polyurethane that had diisocyanates at both chain ends and structure units of PEG400. The resulting network polymer presented a shape memory effect at its glass transition temperature around the melting point of PEG400 as confirmed by dynamic mechanical analysis.
