In this article, effect of the dyeing and mechanical properties were investigated on the polyester ultramicro fiber(UMF) and knitted fabric varying fiber fineness(0.01d and 0.05d). By a treatment with NaOH solution, sea-ingredient was removed and polyester micro-fiber was revealed. The dyeing, build-up and fastness properties of the fiber and fabrics were observed. We used C.I. Disperse Red 60 and Blue 56 for dyeing property and eight Lumacron dyes for build-up property and colorfastness. At low temperature dyeing($100^{\circ}C$), the dyeing rate of 0.01d-polyester UME increased more than that of 0.05d-polyester UMF with Disperse Red 60 and Blue 56 whereas dyeing rate of 0.05d-polyester UMF were increased more than that of 0.01d-polyester UMF at high temperature($120^{\circ}C$), The colorfastnesses of the 0.05d-fiber knitted fabric such as washing, rubbing and light was higher than those of the 0.01d-fiber knitted fabric.

The purpose of this study is to apply the Trencadis images in Antony Gaudi's work to a design motive and thus provide a new concept for a knitwear design by combining double-knitted fabrics with patchwork applique, taping, stitching and quilting. This study examines the bibliographic text and precedent research related to Antony Gaudi and his works, and analyzes the historical background and formative and stylistic characteristics of Trencadis as it appeared in Gaudi's architectural works. Also this study also examines the characteristics of knitwear and knitting theory while exploring the formative elements and the combined techniques used in modern knitwear design through fashion magazines, medium images, and online sources. The results are as follows: First, Gaudi's work that applies a Trencadis technique has the characteristic of being creative, organic, and environmentally friendly. And in addition, its colorfulness inspires modern fashion design. Second, computerized knitting has been practiced in various ways and the fabrics knitted by both double-knitting jacquard and computerized knitting machines provide a new direction the creation of knitwear. A computerized knitting machine is especially effective for pictorial expression, and is suitable for showing the natural curve of the human body due to its sophistication. Third, as a result of applying a combined technique to the knitting of various fabrics, a combined or fusion design, which is a recent megatrend, is very effective for the design of knitwear while increasing its aesthetic value. Moreover, utilizing techniques that combine patchwork applique, taping, stitching and quilting will create higher value in knitwear. Lastly, with a project of applying combined techniques in the creation of knitwear, designers can become much more creative while taking their imagination much further.

The heat of sewing needle is generated through the friction during the needle penetration into and withdrawal from fabrics. Therefore, effects of sewing condition for knitted fabric on the heat generation of needle was examined. The needle size was not the large influence factor of heat generation of needle but the needle point shape significantly affects needle temperature. And the super needle coated with fluoro resin had more effect on reducing the heat of needle. The decrease of sewing speed and the increase of stitch rate had more effect on the reduction in needle temperature. Also the Influence of a sewing thread on the needle temperature was very large compared with bare needle. As expected, an increase in the number of fabric layers result in higher needle temperature.

The purpose of this study were to analyze the effect of weft knit structural characteristics on the subjective texture and sensibility. For this, the material was knitted into 8 kinds of weft plain knit fabrics with four kinds of fiber components such as wool, acryl, rayon, and nylon, 3 steps of densities and 3 steps of twist numbers to ply two yarns. The data were analyzed by factor analysis, ANOVA and multidimensional scaling. From factor analysis, subjective textures were categorized as 'bulk/resilience', 'surface/density' and 'soft/drape', and subjective sensibilities were categorized as 'natural/comfortable', 'feminine/elegance' and 'stable/neat' Among the knit structural characteristics, the component of fibers and the density of fabrics were the important factors to give variations in texture and sensibility : In comparison with wool knit of medium density, the knit fabrics of other components and different densities each showed a unique texture and sensibility. But twist number to ply two yams had a few influence on subjective properties. As a result of MDS analysis, the texture and sensibility of plain weft knit fabrics was classified as 'thin-full', 'hard-soft', 'young-old' and 'warm-cool'.

편성물은 신축성이 좋으므로 의류용 소재로써 다양하게 사용되어지고 있다. 편성물의 장점으로는 직물과는 달리 루프 형태로 얽힌 편환으로 구성되어 있기 때문에 제편 과정에서 필요한 형태로의 성형이 용이해서 제품의 다양화를 기대할 수 있다. 뿐만 아니라 신축성과 유연성, 다공성, 구김안정성 등이 우수하여 인체의 여러 가지 활동에 따른 구속감이 적으며 인체의 굴곡을 아름답게 나타내어 주는 등의 장점이 있어 의복 소재로써 차지하는 비중이 높다. (중략)

경편성 분야는 생산 특성상 소재 원사가 균제하고 강도가 높아야 하므로 주로 사용할 수 있는 원사가 폴리에스테르, 나일론 등의 합섬 필라멘트사에만 주로 한정되어, 새로운 소재를 찾기 위해 노력 해왔다. 그러므로 경편성은 PTT 원사를 대량으로 소비할 수 있는 잠재적인 가장 큰 시장이다. 그러나 PTT를 경편성의 소재로 사용하여 새로운 수요를 창출하기 위해서는 PTT 경편성물과 기존 합성 필라멘트를 소재로 한 경편성물의 물성과 태의 차이가 우선 파악되어야 하며, 정경, 편성 및 형태안정 과정(relaxation)에 관한 연구도 진행하여 새로운 소재에 알맞은 공정 조건이 설정되도록 해야 한다.

Power net fabric is one of the highly extensible two-way fabrics. Power net structure shows special characteristics in the wearing of final functional clothes. This research evaluated effects of treatment temperature on proportional extensibility and shrinkage ratio of spandex at a given wale length. As treatment temperature increased, extensibility increased proportionally to the standard length of the sample and the shrinkage ratio in the direction of course and wale increased. The pulling-out length increased proportionally to the standard length of the sample. However it was affected by the effect of treatment time and temperature due to the thermal properties of spandex filament yarn.

Fuzz on the fabrics, which is the fibers protruded from the fabric surface, is very important in view of appearance quality, since it causes unpleasant appearance on the fabrics and also leads to pilling which makes fabric appearance and soft­ness worse. However, fuzz on fabric surface is measured mostly by subjective methods (human vision) rather than objective methods. Thus, in this study, objective method using image analysis techniques has been developed for the measurement of fuzz on fabric surface. Fuzz on the fabric has also been ranked and rated by experts in order to see the reliability of the results obtained from the fuzz measurement. It was observed that correlation coefficient (r) between rating value and objective mea­surement value was 0.9 and this correlation coefficient value confirmed the reliability of this method.

This research studied how to develop tight upper sportswear from 3D scan data considering fabric stretch property. Subjects were five Korean men of average figure in their 20's. Scanning was done for ten postures via vitus smart/pro(Techmath LTD). Analyzing from 3D scan data, more than 70% of the upper body surface showed surface change rate under 20%. It was shoulder and under arm side part that showed most noticeable body surface change when moving. A parametric model with convex surface was generated and flattened onto the plane, resulting 2D pattern. The error rate occurring in the process of 3D to 2D conversion was 0.2% for outline and 0.13% for area, respectively. Thirteen kinds of stretchable fabrics in the market were collected for this study. Stretch property was in the range of 16.0~58.2% for wale direction; 23.1~78.4% for course. Based on wear trial test, four fabrics were chosen for making the 1st experimental garment and finally one fabric was chosen for the 2nd one, which was developed applying 4 kinds of crosswise reduction rate on 2D pattern: 0, 5, 10, and 15%. Through wear trial test and garment pressure measurement, experimental garment applied with 10% pattern reduction rate was evaluated as most comfortable and considerable.
