The density of fabric is a very important parameter in many fabric production processes. However, in the textile fabrication factories, textile density measurement process has been done inefficiently by handicraft. Thus, exact textile density measurement process is necessary to fabricate high quality textile through weft straighten. In this paper, we propose an automatic textile density measurement system to measure textile density automatically and to improve fabrication efficiency. The proposed system uses cylindrical lens to optically scan the weftl information of the fabric as well as convex lens to enlarge the weft images. The proposed system improves textile quality and provides constant density value to the whole textile range in the high speed fabrication process.

This paper deals with the grey fabric deformation during relaxation. It investigates the effect of twist direction and twist liveliness on the 2/2 twill weave woven fabric distortion, during relaxation This experimental work shows that twist liveliness increases the natural tendency of the twill weave woven fabric to skew. In addition when the twist direction of the warp and weft is opposite to each other the bias curling occurs too.

In this research, an internet-based fabric information system has been developed. Recently, the numbers of textile industries which have their own homepages to advertise their product fabrics fur apparel through the Internet and textile e-Commerce web sites rapidly increase. Unfortunately, traditional fabric information systems based on direct meeting and trust cannot give sufficient information to numerous visitors of the Internet sites including fabric buyers for apparel. They can just view 3-dimensional fabric images and text-based specifications such as fabric density, composition, colors, weight, etc. To solve these problems, the new fabric information system fur apparel has been developed. The web-based fabric information system is composed of the following six modules; $\circled1$ fabric database management system, $\circled2$ a 3-D fabric drape image viewer to illustrate fabric appearances, $\circled3$ a virtual wearing system to apply a fabric to garment designs, $\circled4$ a fabric property viewer to confirm fabric characteristics, $\circled5$ a QC (quality control) document generator to manufacture high qualify garments with a fabric, and$\circled6$actual display mall to view actual fabrics. The fabric information system is simply performed by visitors clicking the buttons hyper-linked with JAVA applets on web browser. The web-based fabric information system enables the web site visitors to understand fabrics shown on the Internet in more details.

Cationic dyeable polyester(CDP) fabric was annealed at varying temperatures range from $120^{\circ}C$ to $220^{\circ}C$ for 1, 3, and 5 min under tension. Dyeing rates of CDP fabrics were measured with cationic and disperse dyes at $100^{\circ}C$ and $120^{\circ}C$ in water system. Also X-ray diffraction pattern, DSC thermograms and dyeability of fabric with cationic and disperse dyes were investigated. The intensities of X-ray diffraction peaks of annealed fabric were increased with increasing in annealed temperature, and peak became sharp with heat setting temperature. The apparent color depth (K/S) of CDP fabric initially decreased with increase of heat-setting temperature up to $160\~180^{\circ}C$ and then increased at higher temperature. The shearing modulus(G) and surface roughness were increased with annealing temperature.

The purpose of this study is to define optimal conditions for wool blend fabric dyeing using Rhus verniciflua extract. K/S value, surface color change, the fastness to light, fastness to dry-cleaning, metal mordanting effects and antimicrobial activities were investigated. The results were summarized as follows; As the storage time of Rhus verniciflua stokes dyeing solution was longer, K/S was improved. K/S value showed the highest one when dyeing temperature and time were at 100oC and 60 minutes respectively. As for the changes of pH values of the dyeing solution, fabric was dyed well with the pH value of acid or neutral. K/S value recorded the highest at pH6 and the lowest at pH10. Fastness to light showed the unmordanted fabric is 2.84, and Fe is 1.69 on color difference. Antibacterial activities of Rhus verniciflua dyeing solution recorded high figures in both dyed fabric with unmordanted and dyed fabric with mordanting.

The effect of cashmere yarn twist, knitted fabric density, and cashmere properties on pilling rates of cashmere knitted fabric is investigated in this paper. The experimental results show that yarn twist and fabric density have little influence on pilling rates of cashmere knitted fabric for yarn 38.4 tex/2 when yarn twist varies from 234 T/m to 272 T/m, and the fabric density is 9.7, 10.7, and 11.2 yarns/inch, respectively. The length of cashmere fiber, in particular less than 7.5 mm, is responsible for the pilling rates of cashmere knitted fabric based on optimal scaling regression analysis.

Global sourcing refers to activities performed to acquire materials, finished products and apparel production all around the world. The purposes of the study were to examine basic job requirements and primary skills of sales team and supporting team in global sourcing companies, to investigate educational programs provided by the companies or other educational institutions, and to examine courses to be newly established in the curriculum of clothing and textile majors. The results of the study found that the ability to use English and communication skills were important to perform their tasks (sales and supporting teams). The results revealed that fabric and textile, sewing, and apparel production process were the most frequently taken educational programs provided by global sourcing companies and English classes were the most frequently taken educational programs in the other educational institutions. The results also found that the clothing and textile curriculum need to add classes that help sales and supporting teams perform global sourcing tasks, such as fashion practical English, fabric and textile, apparel production processes, textile and apparel trades, fiber and fabric testing, and presentation skills. The study suggested educational directions for developing curriculum contents of clothing and textiles and cultivating professionals in the global sourcing industries.

Recently, polyester is widely used in textile fabrics due to its application potentials in various fields. It is known that askin fabric is prepared with mainly polyester and is enjoyed with various end uses such as marine clothing, underwear, shirts, swimming suits and so on. For this purpose, color fastness should be considered with great importance during its wet processing step. In this context, vat dyes were very much attracted due to the advantage of superior fastness property. Thus, we have used indigo dye towards askin fabric dyeings and investigated corresponding properties namely, dyeing temperature, concentration of dye, reducing agent amount and alkali amount. The results showed that higher color strengths of indigo dyeing on askin fabric were obtained at $110^{\circ}C$, 8% o.w.f, 3g/l, 5g/l, respectively. The color fastness to washing was considerable generally.

The advantage of enzyme scouring over alkali scouring is that the enzymatic process can be carried in a neutral pH, resulting in less damage on the fibers and a drastic reduction of wastewater. Since the pH of scouring bath is neutral, dyeing can be carried in the same bath. Four different types of scouring and dyeing in a single-bath were performed in this work: continuous scouring and dyeing in one-bath I and II, simultaneous scouring and dyeing in one-bath I and II. The difference between process I and II is the existence of an after-treatment process in the scouring. Dyeing was performed with three major colors(red, blue, yellow) and black to investigate the dye-ability. The absorbency of scoured and dyed fabrics was measured using gravimetric absorbency testing system. The fabric weight loss was measured after the treatment. Although the color depth for the three major colored fabrics treated in a single-bath was lower than the fabric scoured and dyed separately, the fabrics dyed with black did not show much difference. In addition, the absorbency of fabric treated in a single-bath was higher than the fabric treated separately.
