  • Conventional pad- dry-cure(thermo-fixation) process usually produces functional performance on both sides of a fabric. UV curing technique was applied to impart water- and oil-repellent finish effective only on the face of a PET knitted fabric. The preferential one-side coating, by virtue of the limited penetration of UV light, was achieved by W curing after padding of a fluorocarbon agent without special coating or printing equipments. The difference in the functional property of face and back sides was examined by measuring water and oil repellency at each side of the treated fabric. The influence of pre/post-irradiation dose and agent concentration on the performance of the finished fabrics were investigated. While increase in both resin concentration and post-irradiation did not have significant effect on the finish, UV pre-irradiation of PET fabrics caused remarkable influence presumably due to appropriate surface modification of PET fabrics required for facile wetting of the resin. The dimensional stability and color change of the UV cured fabrics measured by FAST and reflectance spectrophotometry showed significantly decreased color difference and increased percent extension compared with the samples pre-irradiated without agent application.

  • This study develops triacetate-containing functional fabrics with a cool-touch and cool-absorbent. For this purpose we used composite yarns made using triacetate filament and PET High absorbance quick dry filament as well as the composite fabric woven. The fineness of the yarn and structure of fabric varied the cover factor varied. The blend ratio of triacetate was differently set. When the triacetate content was the same, the cool touch of the fabric having a large cover factor and small SMD increased. The surface became smooth and the contact area became large; in addition, both the Qmax value and the cool-touch became large. In the case of similar density, the cool-touch of the fabric having a large content of triacetate increased. The cool-absorbent of the fabric containing triacetate showed a similar level of the PET High absorbance quick dry filament fabric treated with and endothermic cooling agent. It was possible to develop a functional coolness fabric with a cool-touch and a cool-absorbent when the content of triacetate and cover factor were well combined.

  • This study provides improved wrinkle recovery and UV protection capabilities as well as an antibacterial and deodorizing function to linen fabrics for summer shirts. The results obtained from this study are as follows. By setting catalyst concentration to 1.2% and DMDHEU concentration to 6% respectively and applying a heat treatment to them at $160^{\circ}C$ for 5 minutes, the decrease of fabric strength could be minimized and the crease resistance of linen fabrics improved. Compared to the treatment with DMDHEU only, the crease resistance of linen fabrics could be maintained and degradation of their properties could be more effectively prevented by applying the mixture of the UV absorber and the nano silver to the DMDHEU resin. The UV protection of fabrics could be improved by adding the UV absorber. Although the separate treatment of resin or the nano silver had no effect on the improvement of the UV protection properties for treated fabrics, they could increase the UV protection capability when they were combined with the UV absorber. Linen fabrics could possess an antibiosis and deodorizing capability by applying the mixture of the UV absorber, the nano silver, and the resin. The UV protection, crease resistance and flexibility of finished fabrics were maintained even after laundering. Washed treated fabrics maintained excellent antibiosis and odor free capabilities compared to untreated fabrics.

  • This study investigated fabrics, washing and cares, design, pattern, subsidiary materials, and sewing methods with a focus on the functional outers using moisture-permeable waterproof fabric as a shell; in addition, each element was analyzed for differences depending on fabric type. The characteristics of 34 outers were investigated through labels, online product introductions, visual inspection, observations from two experts with more than 30 years experience and wear tests. Moisture-permeable waterproof fabrics used for the outer were classified into two types; in addition, the shell of the high-density fabric and the 2 & 3-layer fabrics had different characteristics. Various fabrics, detailed designs, and three-dimensional patterns suitable for each part of the human body were used to improve functionality. In addition, various subsidiary materials and sewing methods were used to form an organic relationship. The same washing and cares, patterns and subsidiary materials were used regardless of fabric type; however, the fabric type influenced the detailed design and sewing. The outers with high-density fabric had a loose fit, short placket, e-banded cuffs, lock-stitch, and lock-stitch+binding. However, the outer with 2 & 3 layer fabric had a slim fit, hood width adjustment, zippered pockets, cuffs with tab, seamless adhesive sewing such as laminating, lock-stitch+ seam-sealing, and welding.

  • UV-curable water-repellent finish was carried out to impart one-side repellency to the PET fabrics using a formulation of a UV-active fluorocarbon agent and a water soluble photoinitiator. The aqueous formulation was padded on the PET fabrics and it was subsequently UV-cured. The unirradiated side of the cured fabrics was made to wetteable to water by the prolonged UV/ozone irradiation. The influence of photoinitiator concentration, agent concentration and UV energy for photodegradation on the performance of the finished fabrics were investigated. The difference in the functional property of front and back sides was examined by measuring water repellency at each side of the treated fabrics, which resulted in four rating difference between two-side. The UV-cured and photodegraded PET surfaces were characterized by ATR, ESCA and FE-SEM.

  • The purpose of this study was to develop the High Functional Stretch Yarns and Woven Fabrics to produce the high value added textile goods and to meet the consumer's needs. For the study 8 yarns and 10 fabrics were made with three develop machine and the thermal-stress properties of the sample were tested and analysed. The result indicated that the sample fabrics kept their stretch performance regardless of conventional process. EDY(elastic DTY) had higher stretch than that of DTY(drawn textured yarn). Especially Macel yarn had higher stretch than that of DTY compared with the same condition of yarn. With time course behavior the elongation of DTY and EDY had stabled tendency without variation. The above results show that wearing sensation and comfort properties of fabrics are changed depending on the end-use. and thus, above results can be used to manufacture of fabrics for specific end-use with high comfort properties.

  • The effect of high purity chitosan was studied on its application to the natural dyeing using Rhusjara ica. In the dyeing experiment, examinations were introduced on the difference between the chitosan treated fabrics and chitosan untreated fabrics, and on the difference according to the type of mordanting agents and the mordanting methods. Dyeing was carried out for the chitosan treated and untreated fabrics under the conditions of non-mordanting and Al, Sn, Fe mordanting. As a result, we found that, in the case of cotton, chitosan untreated fabrics were not dyed enough, and the dyeing effect was not developed even though the mordanting was introduced. However, the chitosan treated fabrics developed excellent dyeing result even in the non-mordanting case. Through the results of cotton fabric dyeing, it was presumed that the dyeing affinity of the chitosan toward the Rhusjara ica, which prefer specific dyestuff (mainly black color), is selectively high. In the case of nylon, the dyeing effect is not developed easily under all conditions regardless of the chitosan treatment or the mordant treatment. It was inferred that a certain portion of the Rhusjara ica dyestuff made direct bonding with the functional elements in the nylon molecules without the help of the mordant. Through the results of nylon fabrics, it was presumed that some functional elements of the nylon molecules had selective affinity toward the specific colorant (mainly yellow color) of the Rhusjara ica.

  • Most silk fabrics are produced only after the degumming process to make the best use of the properties and have restricted silk processing that do not hinder their performance. However, considering the highly increased preference for natural fibers and the shortage of raw silk, high-quality upgraded silk product functions are required by the development of a processing technology and a good design. This study analyzes the changes with the samples by the functional finish such as softening finishing, wash and wear, tannin weighting by measuring the objective hand of scoured silk and three finished ones using KES-FB. As a result, the change of objective hand of finished silk fabrics that improves functionality was analyzed and compared. The increase of KOSHI after the finish became stiffer show that the silk fabric samples are appropriate for summertime clothes with the retention of a certain clothing climate for the body. The stiffness of finished fabrics for the normal had a closer relationship with the density of fabrics than the type of finishing. The samples (after the softening finishes) maintain better elasticity according to the properties of the softener and the finishing agent. Although the specimens of this study were thin fabrics, their elasticity against compression increased after the softening finishes and became softer than degummed silk. The surface properties of georgette were changed by all types of finishing.

  • Now in the 21st century, all the industries in our world are rapidly changing, including fashion trends and customers' needs as well. Fashion textile planning is also developing towards the direction where it could satisfy the merged sensitivity and incentive of the customers through an idea. The purpose of this study is to accentuate the importance of fashion material planning in fitting conventional patterns and eco-benign fabric materials. Accordingly, this study is mainly focused on the reflection of fabric planning characteristics to show tradition containing comfort and naturalness. As mixing with established fabrics and blending with natural/functional fabrics, and conforming to the trend of the seasonal fabric, it has developed a new structure and pattern by changing the basic source of traditional patterns to a computer aided design system. Therefore, four different types of items were basically up-graded by fitting it in with traditional patterns.
