In recent years, the water-based ink have been widely used in various industrial applications due to environmental problems. Dispersibility of the pigment for applications of the water-based ink is the one of the most important technical factors to produce uniform color products. Thus, in this study, the three-roll mill process was used to improve the dispersion of the water-based ink. The results indicated that the three-roll mill reduced the size of pigment particles in the ink more than 50%. In addition, the dispersant showed an important role to maintain the dispersion stability of the pigment in the water-based ink over 120 hours. We also confirmed the optimum contents of the ink stock solution, drying temperature and drying time by the colorimeter and colorfastness tests on produced PET synthetic suedes.

The purpose of this study is to examine the type of stitch and designs of knitwears using handcraft ornament techniques. This paper will also go on to develop and merchandize high value generated by design development. Knit is largely divided into weft knit stitch and warp knit stitch which are respectively woven by weft knitting machine and warp knitting machine. For clothing, circular knit and flat knit are frequently used while plain stitch, rib stitch and purl stitch are perceived as the basic stitches. Denbigh stitch, cord stitch, atlas stitch, which belong to tricot stitch, are the basic of warp knit stitch. There are also numerous fancy fabrics adapting the previously mentioned stitches and these are made into solid pattern and yarn dyed pattern. The handcraft ornament techniques in knitwears design are embroidery, beads, sequin, stone, printing, applique and fringe, etc. By applying these techniques thus creative expression, which cannot be expressed in other fashion items, is feasible. The women's knitwears are tries by mixed and various techniques, develope to high value knitwears, escaping from simple and practical items.

The purpose of this study is to investigate water and after vapor transport characteristics of underwear fabrics. Experimental materials were cotton woven fabric and cotton knitted fabric, nylon tricot (untreated and hydrophilic finished) and cotton/polyester/cotton triple layer. Cotton knitted fabric have three types of knit structure (interlock, rib, plain stitch) and knit with either 38's or 60's combed yarn. And cotton woven fabric have plain weave with 60's combed yarn. As experimental methods, vapor cup test, dynamic method, vertical wicking test and transplanar uptake test were used. The results are as follows. 1) In cotton specimens, the order of water vapor transpiration (wvt) was plain > rib > interlock in the same yarn diameter. The knit fabric of thinner yarn showed the better wvt among the same knit structure. 2) In cotton specimens, the order of water absorbency was interlock > rib > plain in the same yarn diameter. the knit fabric of thicker yarn showed the better absorbency among the same knit structure. 3) When knit fabric (60's plain) is compared with woven fabric 960's plain), knit fabric showed faster rate of wvt, more amount of uptake and slower rate of water uptake than woven fabric did. 4) When compared untreated nylon with hydrophilic finished nylon, hydrophilic finished nylon showed much more water absorbency than untreated nylon did, but showed same rate of wvt. 5) The water transport characteristics of triple layer underwear fabric showed that the thinner and the lighter one, the better wvt and absorbency did.

Three-dimensional virtual fitting has become a trending practice in the fashion industry because of its productivity benefits, allowing garments to be virtually worn by avatar models without physical production. This study analyzed the variables influencing clothing pressure in both real and virtual fittings to expand the potential utility of pressure data derived from the latter. For this purpose, six sets of compression garments were created by combining two types of tricot fabrics and three types of reduced-pattern tops, with the clothing for real and virtual fittings having identical dimensions. Focus was directed to analyzing the correlation among clothing pressure, surface area deformation, and the mechanical properties of the fabrics. In real fittings, clothing pressure was influenced by multiple factors, including garment design, pattern reduction ratio, body shape, and fabric properties, consistent with existing knowledge. In virtual fittings, however, only the digital mechanical characteristics of the fabrics significantly influenced clothing pressure. The findings suggest that a more reliable implementation of clothing pressure in virtual fitting programs necessitates an approach that considers the complex structural information of garments.

The lengthwise and widthwise deformation of warp-knitted fabrics with different sizes and loading modes were evaluated. Moreover, five tricot samples cut in three directions were compared under four test conditions (A-D). In tests A and B, 500 and 250 g loads were applied on a layer of 20 × 20 and 5 × 10 cm² samples, respectively. In test C, a 20 × 20 cm² sample was folded in half over a rod, and 500 g load was applied to each half. In test D, a 20 × 20 cm² sample was sewn in a loop and subjected to a 500 g load. The lengthwise extension and widthwise contraction analysis results indicate that test B affords the largest values. However, analysis results of the warp-knitted fabric normalized through conversion to a 1 g load and 1 cm sample width indicate that the largest values are afforded for test D. Therefore, pattern reduction may vary depending on the measurement method and properties of the knitted fabric used for the compression wear production, causing variations in the finished product. Thus, an appropriate measurement method must be adopted based on the compression wear design and knitted fabric to be used.
