Stretch fabrics are wide-spread for high performance clothing use with requirements of fitness and adaptability to human's movement. A newly developed 100% PET high stretch fabric has excellent properties with respect to stretch, softness, bulkiness, and apparent volume compared to PET filament fabrics. The 100% PET high stretch fabric shows advantages of a dimensional stability, dye and agent adaptability in dying and finishing process, a property of stretch recovery after washing and lower production cost than that of spandex fabric. KES-FB was used to measure mechanical properties to various directions of the fabric. This study centered on whether the 100% PET high stretch fabric is suitable to quality and shape retention of fabric by testing several properties including tensile, compression, shear, bending and surface characteristic to various measuring directions. Tensile linearity showed maximum value at $0^{\circ}$ in plain and $90^{\circ}$ in twill. Shear Stiffness of plain and twill showed maximum value equally at $45^{\circ}\;and\;135^{\circ}$. Bending rigidity showed maximum value at $0^{\circ}$ in plain and $45^{\circ}$ twill. Mean deviation of MIU showed maximum value at $0^{\circ}\;and\;90^{\circ}$ in plain and $135^{\circ}$ in twill.

This article aims to determine the interrelation among exfoliation strength, the repeated laundry number, the coefficient of friction and the cover factor about the fusible interlining produced by using different amount resin. The practicality of stiffness and warmth of the fusible interling were examined. The results are summarized as follows: 1) As a factor that affecting the exfoliation strength of fusible interlining, the coefficient of friction and the cover factor about the fusible interlining produced by using different amount resin. (2) Regardless of the weight of the resin, the exfoliation strength of fusible interlining declined gradually as the repeated laundry number increased. This tendency arises much more in the case of the filament yarn fabric than in that of the spun yarn fabric. The stability of the exfoliation strength was better, regardless of the increase of the repeated laundry number, when the weight of the weight of the resin was 10 g/$m^2$. (3) The spun yarn fabric, which has more fuzz than the filament yarn fabric, is more suitable for the fabric of fusible interlining. The smaller the cover factor difference between the face cloth and the interlining cloth, the stronger the exfoliation strength. (4) When the stability of the shape is a necessary factor in the consumption of the fusible interlining, a resin weight of 20 g/$m^2$ is the most suitable; however when stiffness and warmth are necessary factors, a resin weight of 10 g/$m^2$ is the most suitable.

This study aims to carry out the experimental and numerical investigation on the flexural behavior of sandwich honeycomb composite (SHC) beams reinforced with novel triaxially woven fabric composite skins. Different stacking sequences of the carbon fiber reinforcement polymer (CFRP) laminate; i.e., 0°-direction of TW (TW0), 0°-direction of UD (UD0), and 90°-direction of UD (UD90) were studied, from which the flexural behavior of SHC beam behaviors reinforced with TW0/UD0 or TW0/UD90 novel laminated skins were compared with those reinforced with UD0/90 conventional laminated skins under four-point loading. Generally, TW0/UD0 SHC beams displayed the same flexural stiffness as UD0/90 SHC beams in terms of load-deflection relationships. In contrast, TW0/UD90 SHC beams showed a 70% lower efficiency than those of UD0/90 SHC. Hence, the TW0/UD0 laminate arrangement is more effective with a mass reduction of 39% compared with UD0/90 for SHC beams, although their stiffness and shear strength are practically identical.

The aim of this study is to create smart wear that brings out the perspective person's individuality and creativity wearing these garments through various interactions. It is intended to build a prototype for a "Shape-folding Dress", which is length-adjustable skirt that responses with the environment of the wearer. In this process, four basic physical properties can be identified with fabric samples selected which are relatively stiff, including fusible interlining, organdy, silk, and ramie. In addition, two types of folding pattern specimens, "Basic Pattern" and "Diamond Pattern", and heat-steam were used to make the specimens so that the correlation could be calculated by recovery rate among flexing, stiffness and tensile properties. As a result, compared to other fabrics, the silk showed low stress to repeat folding and unfolding process, and its recovery rate of elongation deformation was stable without being affected by the different folding types and twice repeated process. In this study, forming a circuit using an Arduino, illuminance sensor, motors, and pulley, the prototype was created with a silk fabric.

This paper proposes a bi-component dye, including the unripe fruit of Diospyros kaki THUNB and Ecklonia cava, to substitute for traditional persimmon dyeing because fabrics dyed with persimmon juice become stiffer and natural persimmon is insufficient for dyeing. This study examined the color difference and fabric stiffness depending on the ratio of Ecklonia cava for in a one-bath dye solution with Diospyros kaki THUNB and showed that 6% of Ecklonia cava in the bi-component dye was the optimum for decreasing the fabric stiffness. Based on these results, a bi-component dye constituting of 94% Diospyros kaki THUNB and 6% Ecklonia cava was prepared. The particle size was found to be smaller than both single dyes and it maintained a similar amount of Catechin to Diospyros kaki THUNB dye. Finally, cotton fabric dyed with a bi-component dye was much improved in terms of the fabric hand and the surface color was similar to that of the traditional persimmon-dyed fabric. These results could help to develop the natural persimmon dyeing industry.

This study was carried to figure out the effect of bleaching on the cationic surfactant (DSDMAC) absorption by cotton fabrics. And physico-chemical change, static electricity, and fabric stiffness of bleached cotton fabrics were measured. Cotton fabrics bleached with sodium hypochlorite soluton and with sodium percarbonate solution were used to analyze the DADMAC absorption. The results were as follows: 1. As the number of bleaching cycles were increased, the degree of oxidation on cotton fabrics was increased. So their carboxyl content was increased and their tensile strength was decreased. 2. DSDMAC absorption by cotton fabrics was increased by bleaching and was in propor- tion to carboxyl content. Therefore, it was groved that DSDMAC absorption by cotton fabrics was motivated by ion exchange mechanism. 3. The static electricity of cotton fabrics almost no change when bleached and unbleached absorption had no effect on the static electricity of cotton fabrics. 4. DSDMAC which was absorbed by cotton fabrics acted as a lubricant. DSDMAC absorption reduced the friction coefficient of yarn, so stiffness of cotton fabric was decreased.

In this study, acid cellulase was used to treat denim fabrics by varying pH, temperature, enzyme concentration, treatment time and non-ionic surfactant (Triton X-100) concentration. Treatment condition was controlled based on the weight loss. The characteristics of enzyme-treated fabrics were measured in terms of tearing strength, stiffness, and color difference. The optimum conditions for cellulase treatment of denim fabric were pH 5.0, $50^{\circ}C$, 3% (o.w.f.), 90minutes. The weight loss did not change significantly with the addition of a non-ionic surfactant, but it improved when more non-ionic surfactant were used. The tearing strength of enzyme-treated denim fabrics did not deteriorate. The stiffness of the treated fabrics improved with the enzymatic treatment with and without the non-ionic surfactant. The difference in color of fabrics treated with enzyme increased.

The soil nailing system at permanent slope reinforcement is used with various facing methods in Korea. Also, pressure-injected grout technique is variously applied to many structures. However, most design of the pressure-injected grout technique have been carried out empirically because of complicated mechanisms associated with the behavior of surrounding soils and the hardening process of cement grout. Therefore this study, a newly modified soil nailing technology named as the PGSN (Pressure Grouting Soil Nailing) system with fabric form is developed to increase the global stability. Up to now, the PGSN system has been estimated mainly focusing on an establishment of the design procedure. In the present study, numerical study are carried out to evaluate potential failure surface and minimum factor of safety including facing stiffness and expanded radius of cemented grout by SSR (Shear Strength Reduction) technique. Also, results of numerical analysis are carried out for the typical section of soil nails slope using $FLAC^{2D}$ program for expanded effective radius by pressure grouting.

Cotton fabrics were immersed in aqueous solution of N-methylmorpholine N-oxide(NMMO) with various concentrations, padded by 300% of pick-up, concentrated at $90^\circ{C}$ for 30min under constant-length condition, washed, and dried, to examine a possibility of linen-like finishing by the solvent bonding between fibers. With increasing the concentration of NMMO, cross-sections of fibers changed to oval or polygonal shapes and not only the fibers but also the warp and weft were bonded each other, which produced linen-like effect on the fabrics in the aspects of appearance and mechanical properties such as the Increase of stiffness and shear properties. The thickness, moisture regain and dyeability were increased with the concentration of NMMO.

Quilting, a technique to join two or more layers of fabrics, has long been used in the textile and fashion sectors. To evaluate dimensional effect of quilting that changes according to the characteristics of fabrics, 3D scanning method is employed in this study. Goal of this study is to interpret how fabric's composition, stiffness, thickness, and weight affect the appearance when quilted fabrics are used in a garment. Surface reconstruction method based on 3D scanning is used as a research method to evaluate the changing appearance depending on the material properties quantitatively with the quilting method. Besides, exemplary virtual clothing is realized through a virtual quilting method in 3D digital clothing system based on the properties of fabrics.
