Silicone-coated fabric were treated by oxygen low temperature plasma to improve the adhesion. The surface of silicone-coated fabric was modified with gaseous plasma of several discharge power in the presence of oxygen gas at 1Torr pressure. Oxygen plasma treatment introduces oxygen-containing functional groups and micro-pittings on the silicone-coated fabric surface. The treated fabrics with oxygen low temperature plasma were measured by contact angle analyzer and XPS(X-ray photoelectron spectroscopy), and interfacial adhesion was measured by T-peel test. The surface of fabric was investigated by SEM photographs. The chemical and physical modification of the surface wettabillity by plasma treatment can increase the adhesion.

This research surveys the mechanical properties of worsted fabrics for garment according to the loom characteristics and fabric positions with relation to the warp and weft weaving tensions on the projectile and air-jet looms, which is previously surveyed in the 1st paper. For this purpose, the grey fabrics are processed in dyeing and finishing processes. The mechanical properties of the finished fabrics are measured and discussed with relation to the warp and weft weaving tensions of projectile and air-jet looms and the variations of the fabric mechanical properties according to the fabric positions are also surveyed for investigating the homogeneity of the tailorability and fabric hand.

The purpose of this study is to provide the dyeing and physical characteristics of napped knit fabrics composed of latent crimped yarn. The K/S values, dyeing fastness, thickness, bulkiness, and shrinkage characteristics of three knit fabrics were investigated. The original knit fabric (SK) was composed of 1ply latent crimped yarn (75/36) in the ground and PET DTY (70/100) in the pile loop, in order of napped process the napped knit fabric (SN) was napped SK fabric. In order to compare of latent crimped yarn content, the last knit fabric (DN) was napped 2ply latent crimped yarn were included in the same structure of SK. Dyeability of three knit fabrics was similar but the shrinkage properties of DN fabric were significant different. The bulkiness shows a tendency to increase the bulkiness as increasing the dyeing temperature, and the bulkiness of the SN was higher because of the napping process and optimal content of latent crimped yarn.

In order to investigate the light fastness of amino azo disperse dyes, some kinds of disperse dyes were prepared and dyed to polyester fabric under the different conditions, such as single or mixture state. After the dyed fabric was irradiated with carbon arc light for several hours, the color differences and K/S values of fabric were measured. The light fastness of amino azo disperse dye was decreased by the introduction of OH group to the dye molecule. But when the amino azo dye was mixed with the anthraquinone disperse dye, the light fastness was increased. It was considered that the dye molecules were aggregated on account of hydrogen bonding via OH groups, resulting the decrease of surface area of dye molecule which might be irradiated by the light.

It is well recognized that the wicking of liquids in a textile fabric takes place mainly through a capillary system composed of the individual fibers. Considering typical dyeing stages, it is thought that a high dye uptake on the fabric probably depends on the wickability. Three kinds of barely water soluble ketones, acetophenone(A), 2-pentanone(2P) and 3-pentanone(3P) were separately dissolved in methanol(M) and then each was mixed with aqueous solution of C. I. Red Acid 114. Wicking heights of dyeing solutions were measured under such conditions that the effect of gravity was negligible. The result could be graphed as a series of straight lines having the form s = $kt^{1/2}$, where s was distance traveled by the solutions, t was time, and k was slope of the line. The surface tension(${\gamma}$) of the ketones had more signifcant effect on the wickability compared to the viscosity(${\eta}$) of them. The greater wickability resulted in the higher dye uptake on the fabric and the order of wickabilty was equal to that of the surface tension(${\gamma}$) and dye uptake on the fabric, A>3P>2P>M.

Cationic dyeable polyester(CDP) was produced through melt blending of cationic chips having $2mol\%$ of sodium salt of dimethyl ester of 5-sulfoisophthalic acid(DMS salt) and normal polyester chips in different proportions to obtain yarns having varying amount of comonomer in the fiber. The modified polyesters showed increased moisture regain, decreased viscosity, lower softening point and improved antistatic characteristics, according to the amount of modifier. In dyeing at $100^{\circ}C$ the dyeing rate of cationic dyes with CDP fiber increased slowly than that of disperse dyes. In dyeing at $120^{\circ}C$ cationic dyes reached to equilibrium at 30min and disperse dyes at 10min. Cationic dyes in dyeing of CDP fabric have a better wash fastness compared with disperse dyes, also rubbing fastness of cationic dyes is better than that of disperse dyes. The light fastness of CDP fabric for cationic and disperse dyes is not good. The fastness of 75d/36f CDP fabric is higher than 75d/72f fabric. Solvent wicking fastness of CDP with cationic dyes is better than that of disperse dyes.

Hand characteristics related with structural properties of fabrics have something to do with mechanical properties of fabric. In this study, the mechanical properties and hand characteristics have been analyzed according to fabric structural parameters such as the weave structure and the linear density of weft of cotton fabric. Mechanical properties have been used by KES-FB system which measures hand characteristics and mechanical properties of fabric. Linear density of weft, tensile, bending, and shear properties are decreasing with increasing weft linear density, and there is no considerable effects on compression and surface properties. In case of formability with weft linear density, B/W, 2HG/G, 2HB/B, 2HB/W, $\sqrt[3]{B/W}$, $\sqrt{2HB/W}$, W/T except MMD/SMD, WC/T, and WC/W have been effected. There is a high correlation between the crimp, tightness, hand, formability and mechanical properties specially tensile linearity, bending, shear, and compression properties. The weft crimp influences the bending rigidity, shear properties, and the tightness which have effects on the tensile linearity, bending, shear, compression properties, hand, and formability.

The purpose of this study is to analyze the wearing fitness of middle aged women's jacket with non-Stretchable Fabric and stretchable fabric. We surveyed the size of jackets and process of pattern making with stretchable fabric in companies which produce the clothing mainly for middle aged women. Based upon the result of process of pattern making, two kind of experimental jacket with non-stretchable and stretchable fabric were made. We measured space length between body and garment using 3D scanner and analyzed the clothing pressure 7 parts of body with 3 kinds of arm raising. The result were as follows : 1. Most parts of space length except bust were higher in non-stretchable jacket than in stretchable jacket. 2. Clothing pressure showed greater value with non-stretchable fabric jacket than with stretchable fabric jacket. Clothing pressure in upper arm point areas increased as the angle of the arm raising increased. Therefore, the sleeve width and armhole depth should he considered when the amount of wearing ease were reduced in jacket with stretchable fabric.

Fabric hand is ultimately a subjective response to physical stimuli, but there are clearly practical advantage in the development and commercial trading of textile fabrics to be gained from the replacement of the traditional subjective tactile assessment by an objective measurement evaluation method. Moreover, the reliable objective measurement method for warp knitted fabrics have not developed yet, despite their increasing importance. (omitted)
