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 purpose of this study is to measure, compare, and investigate the physical properties of rayon/cotton blend fabrics treated with cellulase and cellulase & specific degeneration silicon and to present basic data which is in development a value-added fabric. The results are as follows. The condition for the treatment of cellulase was at 55$^{\circ}C$, pH 4 and the weight loss increased as the concentration of cellulase and the treated time increased. On treatment with cellulase, the crossectional view & longitudinal view of fiber noticed remarkable crack as weight loss increased and tensile strength and elongation decreased, and pilling was enhanced remarkably. KOSHI was increased, NUMERI and FUKURAMI were decreased as weight loss increased. In the basic characteristic value of clothing wearning, shape stability and drapability were decreased, but air content was improved. On treatment with cellulase & silicon, the degree of damage in the crossectional view & longitudinal view of the fiber reduced. Tensile strength, elongation, moisture regain improved. KOSHI and FUKURAMI were reduced, NUMERI was improved rather than when it was treated with cellulase. Therefore handle was improved. In the basic characteristic value of the clothing wearing, shape stability, air content, drapability were improved.

The dyeing property of milling type acid dyes with various chemical constitution were studied in one bath dyeing of Wool/Nylon blended fabrics and the proper dyeing condition to get solid color by using reserving agent was also examined. The result of the experiments can be summarized as follows; 1) Although the effect of pH on dyeing of wool with a highly hydrophiilic dye is great in the dyeing of wool and nylon, the proper pH of dyeing bath is weakly acidic 5, in which levelling dye can be obtained by increasing the solubility product. 2) Under a constant pH, the dye with fewer numbers of sulfonic acid groups increases the dyeing amount of nylon as the concentration of the dye is increased. Thus the appropriate dye for light color is the one with many numbers of sulfonic acid groups and the proper dye for medium and deep color is of fewer sulfonic acid groups for one-bath dyeing. 3) When the dye concentration is greater than the critical depth, the K/S value of wool and nylon was almost not effected or slightly increased.

This develops a new and advanced S/S knitwear material made of linen/bamboo blended yarn. Linen/bamboo knitted fabrics were compared with linen/polyester knitted fabrics in terms of appearance as well as physical and comfort properties. Rib knitted fabrics were remarkably thicker than plain knitted fabrics. Knitted fabrics based on polyester yarns were heavier than those based on bamboo yarn. The porosity decreased in the following order: linen 100% > bamboo 100% > polyester 100%. The drape properties of bamboo 100% and linen/bamboo knitted fabrics were excellent. The pilling resistances of linen 100% and linen/bamboo knitted fabrics were excellent. The highest and lowest air permeability was observed in the case of linen/bamboo knitted fabrics and polyester 100% knitted fabrics, respectively. The instant cool-feeling was enhanced as the bamboo yarns were blended. The thermal conductivity of linen 100% knitted fabrics was the highest and the thermal conductivity of linen/bamboo knitted fabrics was higher than linen/polyester knitted fabrics. Bamboo 100% knitted fabrics showed a higher moisture regain than polyester 100% knitted fabrics. The results confirmed the superior appearance and comfort of a novel S/S knit wear material made of linen/bamboo knitted fabric.

This paper was carried out to introduce flame retardant and antibiotic properties to polyester(PET) and polyester/cotton(P/C) blend fabrics. PET and P/C blend fabrics were treated by a paddry-cure method in the aqueous solutions of the finishing agents(JA 6034, JA 6050, DC-5700). The corona discharge technique was applied to increase the polar group of the polymer surface. The characteristics of the treated fabric were investigated by means of scanning electron microscope (SEM) and electron spectroscopy for chemical analysis(ESCA), and water penetration time, limiting Oxygen index(LOI), and K/S value were also measured. Wettability of the fabrics was increased considerably with the corona discharge treatment. ESCA was used to elucidate the surface chemical composition of the fabrics treated with the corona discharge. Relative Ols intensity increased and oxygen was incorporated in the form of -C-O-, -C=O, and O=C-O on the polymer surface. The current study indicated that corona discharge treatment was effective for modifying the polymer surface.

This study investigates the physical properties of Murata Vortex Spinning (MVS) blended yarn with yarn count(20's, 30's, 40's) and blend ratio(Polyester 100, Polyester70:Cotton30, Polyester50:Cotton50, Polyester30:Cotton70, and Polyester50:Tencel40:Cotton10). This study evaluated tenacity, elongation, bending rigidity, bending hysteresis, hairiness coefficient, irregularity and twist number. The structure of MVS blended yarn influenced stress, strain, bending rigidity, bending hysteresis and the hairiness coefficient of MVS blended yarn decreased as the yarn count increased. MVS blended yarn consists of core and sheath. The core of MVS blended yarn is composed of a parallel fiber with a wrapping fiber that covers thecore fiber. This special structure of the MVS blended yarn effects the physical properties of the yarn; in addition, the mechanical properties of the component fibers influenced the stress, strain, bending rigidity, bending hysteresis and hairiness coefficient of MVS blended yarn with the blend ratio. Polyester decreases and cotton increases resulted in decreased physical properties. A similar polyester content increased the tencel and physical properties. Appropriate physical properties and a variety of touch expression can be realized through a correct blend ratio.

This study examined the effect of the blend ratio of wool and polyester fibers, yarn and fabric structural parameters to the appearance property and the formability of worsted fabrics. The mechanical properties of twenty types of manufactured worsted and PET/wool blend fabrics were measured using KES-FB and FAST systems. Garment formability increases with the thickness and cover factor as well as increases with wool content. The correlation between KES-FB and FAST system showed a relatively high correlation with an extensibility of 0.98, bending and shear rigidity 0.71; both were higher than polyester synthetic fiber. The correlation coefficient of garment formability between KES-FB and FAST systems was 0.93 and the correlation coefficient between formability and fabric extensibility was 0.8. These results were higher than those of bending and shear rigidity. This revealed that garment formability was influenced by wool content, cover factor and fabric thickness; however, wool content and fabric thickness were the most important factors for the seam pucker. The garment formability of the worsted fabrics can be predicted by fabric mechanical properties measured from KES-FB and FAST systems.

In one bath dyeing system of silk/cellulose acetate fiber blend fabric with acid /disperse dyes, adsorption behavior of acid dyes and disperse dyes on silk and cellulose acetate fabrics were examined. In the dyeing of cellulose acetate with C. I. Disperse Red 19(Red 19) and C. I. Disperse Red 60(Red 60) at 8$0^{\circ}C$ and 10$0^{\circ}C$, dye uptake with Red 19 was higher than that with Red 60. When the silk/cellulose acetate dyed with Red 19 and Red 60 at 10$0^{\circ}C$, dye uptake on cellulose acetate was influenced by affinity of the dye to the silk fabric dyed together. When the silk/cellulose acetate dyed with Blue 80/Red 19 and Blue 80/Red 60 at 10$0^{\circ}C$, color of cellulose acetate dyed with Red 19 and Red 60 was not influenced by Blue 80 but silk dyed with Blue 80 was influenced by Red 19 and Red 60. Interrelation of K/S value and Munsell value was scarcely any but showed the change tendency of K/S value.
