Cationization is effective to complement the defects of Tencel blended fabrics by introducing new functions. For this purpose, we used chitosan, which is congenial to the human body, free of pollution, and easily reacted. Then, we compared it to the Tencel single fabrics. To perform such effective cationization, the fabrics were treated with chitosan after NaOH pretreatment and enzyme treatment thereof. After that, the fabrics were treated with a crosslinking agent and a softner. The dyeing property of the cationized Tencel blended fabrics and reactive dye, which is a type of anionic dye, show a high concentration in neutral salt and excellent repulsive power between the fabrics and the decreased dyes. The dyeing property of the chitosan treated fabrics represented better performances than that of untreated fabric in the lower concentration of neutral salt. Meanwhile, when it was dyed with certain acid dyes, the dyeing property of the chitosan treated fabrics showed better results due to the reaction of an amine group, which was introduced by chitosan treatment. Thus, the verification of the cationization of the Tencel blended fabrics was performed. The washing fastness of the Tencel blended fabrics showed a little bit better than that of the Tencel single fabric, and it represented a better performance in the dye with a reactive dye than that of an acid dye.

TThis study explored the requirement of fabric sensor that can measure the motion of the joint effectively by measuring and analyzing the variation in electric resistance of a sensor in accordance with bending and stretching motion of the arm by the implementation of a motion sensor utilizing conductive fabric. For this purpose, on both sides of two kinds of knitted fabric, namely 'L' fabric and 'W' fabric Single Wall Carbon Nano-Tube(SWCNT) was coated, fabric sensor was developed by finishing them in a variety of ways, and the sensor was attached to the arm band. The fabric sensor consisted of total 48 cases, namely background fabric for coating, the method of sensor attachment, the number of layer of sensors, the length of sensor, and the width of sensor. The performance of fabric motion sensors in terms of a dummy arm, that is, a Con-Trex MJ with 48 arm bands around it was evaluated. For each arm band, a total of 48, fastened around the dummy arm, it was adjusted to repeat the bending and stretching at the frequency : 0.5Hz, ROM : $20^{\circ}{\sim}120^{\circ}$, the voltage was recorded for each case after conducting three sets of repeat measurement for a total of 48 cases. As a result of the experiment, and as a consequences of the evaluation and analysis of the voltage based on the uniformity of the base line of the peak-to-peak voltage(Vp-p), the uniformity of Vp-p within the same set, and the uniformity of the Vp-p among three sets, the fabric sensors that have been configured in SWCNT coated 'L' fabric / welding / two layers / $50{\times}5mm$, $50{\times}10mm$, $100{\times}10mm$, and SWCNT coated 'W' fabric / welding / two layers / $50{\times}10mm$ exhibited the most uniform and stable signal value within 5% of the total variation rate. Through all these results of the experiment, it was confirmed that SWCNT coated fabric was suitable for a sensor that can measure the human limb operation when it was implemented as a fabric sensor in a variety of forms, and the optimal sensor types were identified.

In Japan, a country renowned for her traditional respect for handicraft, superior craft techniques have been transmitted from generation to generation. Modern Japanese textiles reinterprete these traditional techniques in a new light and combine them with modern technology, to make modern Japanese industrial textile both futuristic and traditional simultaneously. This combining of new technology and handicraft serves as a reservoir for a remarkable diversity and originality in the development of new technology and design, and constitutes an important trend in modern industrial textiles. The aim of this study is to investigate the developmental background of Japanese textile industry that championed this trend to make the Japanese development unique in modern textile industries and to consider the concept of modern textiles as well as the structural innovation as represented by this new trend, thus contributing to the development of creative textiles for the present and the future. The findings of this study can be summarized as follows. The combining of new technology and traditional handicraft: 1) was made possible by Japanese consciousness that values traditional culture and by early recognition of advanced textile industry, which awarded new meaning and value to the traditional handicraft leading to an expanded social role for textiles. 2) helped construct a modern concept of textiles by pursuing textile media that are state-of-the-art, aesthetic, and highly sensitive to satisfy the requirements of modern industrial textile such as high quality, high performance, and high sensitivity. 3) enabled new design ideas and creation of new styles by implementing structural innovation in industrial textiles that involved diversification of expression, diversity in materials, and emphasis on texture. In short, by combining new technology and traditional handicraft, Japan came up with a new sense of aesthetics that is highly original and high level and with which the rest of the world can easily sympathize, thereby presenting one of the most important guiding principles for future textiles.

During the 1980s, Textile design achieved a remarkable growth in creating aesthetic effect and in establishing its standing by responding to demands of the time effectively and seeking changes proactively. This was a period when Textile design constructed its modern concept as it was attempting a qualitative improvement through advanced technology, high class, and differentiation. The advent of advanced materials through the development of textile engineering, employment of craft techniques to further cultural and artistic orientation, and restoration of decorativeness in pursuit of sensitivity, all these developments of the 1980s contributed to the rise of above characteristics. In this study, attempts are made to grasp the new trend of Textile design during the 1980s and to review diverse methods of aesthetic creation and plastic possibility which this trend presented for the Textile, and thus to recognize the role of Textile design and its importance in a new light. The new trend of Textile design during the 1980s can be summarized as follows: 1) An appreciation of the creative aspect of the Textile. As attempts are made to emphasize visual and sensitive aspects of the medium, Textile tended to become an object of art itself. 2) A new awareness of the representative and plastic capacity of the fiber material. As attempts are made to develope the creative potential of the Textile, representation of the material tended to become more diversified. 3) A recognition of the Textile as a proper means to deliver the spirit of the time. As the medium accommodates and fuses diverse cultures including traditional culture, more emphasis was place on cultural contents of the Textile. In the process of pursuing these changes, Textile design of the 1980s has also contributed to the creation of new values, laying the groundwork for its emergence as an advanced high value-added industry.

In this study, breathable waterproof materials were prepared by electrospinning. Five kinds of electrospun nanofiber web layered systems with different levels of nanofiber web density, as well as different substrates and layer structures were fabricated, and their mechanical properties (tensile, bending, shear, compression, surface, and thickness & weight) were measured by the KES-FB system and compared with those of conventional breathable waterproof fabrics (densely woven fabric, PTFE laminated fabric and PU coated fabric). The KES-FB measurements demonstrate that the lab-scale nanofiber web layered systems are more flexible and fuller than commercial nanofiber web layered systems, which have a more compact structure than the lab-scale nanofiber web layered systems. Densely woven fabrics and lab-scale nanofiber web layered systems showed lower values of tensile linearity (LT), bending stiffness (B), and shear stiffness (G) than those of PU coated and PTFE laminated fabric. These results indicate that they are more flexible and have less resistance to the shearing movement, corresponding to a more pliable material having a better drape, than PU coated fabrics and PTFE laminated fabrics.

Recent years have witnessed that IT-convergence technology has become the most important issue in the global market. Along with this trend, demand for PSS(i.e., Product-Service Systems) design has been rapidly increased in the smart clothing market. A case of the PSS design research, this study aimed to identify optimum conditions for weaving of POF-based flexible textile display(abbreviated as "PFTD") for mountaineer wear with safe-guard function regarding luminescent properties. Based on the findings regarding the optimum weaving condition of PFTD, several designs of mountaineer wear were suggested in this study. A total of 15 PFTD samples were prepared under various weaving conditions of weave structures and density of POF, and the luminance values of each sample were measured. As the results, the types of PFTD with structures and density of 'satin 3:1', 'satin 2:1', 'twill 3:1' and 'twill 2:1' indicated relatively higher luminescence. And based on the results and recent sports fashion trends, two suited mountaineering wears applying PFTD were illustrated in this study.

In this work, we study smart gloves that can prevent carpal tunnel syndrome when using a mouse. Because the left and right wrist movements are fine, a tensile fabric sensor with a large gauge factor and low hysteresis was required before the study. A universal testing machine was used to calculate each gauge rate on four different fabrics, and the fabric with the least hysteresis was selected. In addition, three attachment methods were analyzed using Arduino to select a method with a large sensor value change. For prototypes made by attaching to the selected fabric, data patterns were analyzed using Arduino. The first method identifies only one sensor (A sensor), and the second identifies two sensors (A and B sensors). When the wrist is bent to the right, tensile fabric sensors are attached to both the left (A sensor) and right (B sensor) sides of the wrist, the A sensor is strained, increasing the △sensor value, and the B sensor is relaxed, decreasing the △sensor value. However, when the wrist was bent to the left, the pattern was analyzed in the opposite direction. Through this study, we examined smart gloves to prevent carpal tunnel syndrome with an algorithm that turns on the LED when the wrist is bent, and based on the results of this study, we will directly use mice on 10 people to identify problems and solve problems when used.

For cationization, if chitosan, which has the affinity for a human body and reacts easily without inducing any pollution, is used, cationization of Tencel blended fabrics can be expected and further expansion of its use as a new susceptible material can be expected. Therefore, in this study, in order to compare a Tencel/cotton and a Tencel/Cotton/PET as Tencel blended fabrics with a Tencel single fabric, the fabric samples were used and processed with chitosan after NaOH pretreatment and enzyme treatment thereof, and then its adherent efficiency was enhanced by using a crosslinking agent, and then it was got to be finished with a softener. The fibril of Tencel fabric was controlled by enzyme treatment so that the surface of the Tencel blended fabrics got to be smooth. Chitosan adhered to the surface of the Tencel blended fabrics in the form of particles through its processing with chitosan. Chitosan treatment caused little change in the crystal structure thereof and the thermal stability of the Tencel/Cotton/PET fabric was slightly improved. The total hand value(THV) calculated on the basis of the change due to chitosan treatment was increased in all samples.

This study compares general jacquard fabrics and jacquard fabrics with optical fiber on mechanical properties, sensibility and preference evaluation of fabric for the blind. The analysis also assesses the effect of optical fiber in the evaluation and identifies those best suited for consumers. The mechanical properties of jacquard fabrics were measured by the KES-FB system. Sensibility and the preference of the jacquard fabric for the blind were rated on tactile sensation by women experts in their 20's and 30's. It was found that the optical fiber in jacquard fabric affected the change of mechanical properties as well as sensibility and preference. Jacquard fabric with optical fiber were softer and more transformable, while the fabrics had lower recover property by shear force and compression as well as more violent unevenness. Jacquard fabrics were also classified into three hand factors of surface property, resilience and weightiness. There were significant differences on surface property perceptions and weightiness, hand and blind preferences by optical fiber. Jacquard fabrics that contained optical fiber were not preferred by the blind because they were perceived to be uneven and heavy. Those, that were smooth and light, were preferred for jacquard fabric; in addition, fabrics preferred by the blind had good compression.
