The purpose of this study was to evaluate the physical properties and handle of knitwears made with silver yarns. The four different knitted fabrics were made and compared: cotton(C), cotton/silver(CS), polyester(P), and polyester/silver(PS). If fabrics knitted with silver combined yarns, their electrical shield properties, UV-cut properties, anti-static properties, and air permeability were improved. As an additional effect this also improves the antibacterial properties of fabrics. It was found that overall physical properties and functional properties were improved by using silver yarn with cotton. The silver knitted fabric was found to be improved its softness and fullness hand for apparel.

The bending properties, wrinkle resistance, and fabric retention behaviors of cotton knitted fabrics in the wale and course directions were studied for their dependence upon resin finishing, knit structure, and washing cycles. Stiffness, wrinkle recovery angles, and dimensional stability were investigated before and after resin finishing and laundering. It has been found that any change in the physical properties of the knitted fabrics with respect to knit structure and fabric directions are related to accompanying modifications to the state of the fiber properties. The decrease of fabric shrinkage rates and wrinkle recovery properties from increasing laundering cycles is related with resin incorporated on the fiber surface. This study shows that resin finishing on knitted fabrics can be performed only to improve fabric retention properties with reduced wrinkle recovery properties.

The cotton, wool, cotton/wool blended(80:20) and tencel fabrics were treated with low temperature oxygen or argon plasma, enzymes(cellulase or protease), or oxygen plasma-enzyme and examined for their weight loss and conditions for treatment for the environment friendly finishing. In the plasma treatment argon gas had better effect on the weight loss than oxygen gas did and the weight loss of all the fabrics was increased as increasing discharge power and discharge time. The weight loss of cotton, wool, cotton/wool blended(80:20) fabrics decreased in a large measure after 1 hr but that of tencel didn't decrease after 1 hr. In case of cellulose fibers oxygen gas plasma induced chemical functional groups on the surface of substrate more than argon gas plasma did so the weight loss of wool was larger than that of cotton, tencel fabrics in oxygen plasma-enzyme treatment. The weight loss of cotton and tencel fabrics decreased the initial stage because oxygen plasma pre-treatment caused cross linking as well as etching effect but argon plasma pre-treatment didn't. The plasma pre-treatment cleared the way for enzyme treatment on the whole but oxygen plasma pre-treatment bear in hand the increase of weight loss more or less because of the cross linking on the surface of cellulose fibers. The appropriate conditions for plasma treatment was 10-1Torr, 40W for 30minutes and for cellulase treatment were enzyme concentration of $3g/{\ell}$, pH 5, $60^{\circ}C$ for 1hr and for protease treatment were enzyme concentration of $4g/{\ell}$ pH 8, $60^{\circ}C$ for 1hr.

In this study, a cotton knit was dyed with elm bark extract; subsequently, the dyed fabric was measured according to the types of mordants and the preprocessing cationizers used. Additionally, antibiosis against super bacteria was examined. The results follow. First, the color of the dyed cotton knit appeared reddish and yellowish for fabrics treated with non-mordants and mordants. When preprocessing with a cationizer was conducted, the dyeing properties were the best. Second. even when mordants were not used for dyeing, color fastness after washing, sweating, and rubbing was generally good Grade 4 and 5. Color fastness after exposure to sunlight was the best Grade 4 for fabric prepared with ferrous sulfate as the mordant. Third. as for antimicrobial properties, or resistance to super bacteria, the growth of bacteria was suppressed in a meaningful way for fabrics treated with non-mordants and mordants, compared to the control group fabric. The dyeing methods with the most powerful antimicrobial effects were dyeing after preprocessing with a cationizer and preparing fabric with copper sulfate as the mordant. The results stated above show that in case of dyeing with elm bark extract, preprocessing of the cotton knit with a cationizer and dying with copper mordant displayed high levels of antimicrobial properties that were useful for resisting super bacteria. Of these the dyeing properties were the best when preprocessing with a cationizer.

The purpose of this research was to analyze the residual water retention and to determine the number and species of microorganisms from the wet cotton fabrics in dehydration and drying process during washing. The drying rates of terrycloth and interlock knit under the rainy seasons were measured according to the dehydration and hanging methods, layers of fabric and pre-treatment agents. Microorganisms were isolated from the dried terrycloth by pure culture, and were identified by Biolog system. The results are as follow: The initial water retention of fabrics after dehydration decreased in the order of dripping>centrifuge>squeezing method, which affected the drying rate. The drying rates were faster by increasing surface area of fabrics. There was no significant difference in drying rate among the fabrics pre-treated with detergent, or fabric softener, or cationic surfactants such as Cetyltrimethylammonium bromide(CTAB) and Benzalkonium chloride(BC). Puedomonas aureginosa was found in the fabrics treated with a powder-type detergent. On the other side, there was no growth of microorganism in the fabrics treated with a liquid-type detergent (containing antibacterial agent), CTAB and BC.

Cotton, wool, cotton/wool blended (80:20) and tencel fabrics were treated with low temperature oxygen plasma, enzymes (cellulase or protease), or oxygen plasma-enzyme and they were examined for dyeing and handling properties for environment friendly finishing. The appropriate conditions for cellulase treatment were enzyme concentration of 3g/l, pH of 5, and $60^{\circ}C$ for one hour, and for protease treatment were enzyme concentration of 4g/l, pH of 8, and $60^{\circ}C$ for one hour. The equilibrium uptake of a direct dye on cotton changed with plasma treatment and plasma-cellulase treatment, and the rate of dyeing slightly decreased. When wool was dyed with acid dye, the equilibrium dye uptake did not change with plasma, protease treatment nor plasma-protease treatment, however, the rate of dyeing had increased with plasma-protease treatment. From these results, it is assumed that plasma attacks the surface of the fiber, and enzyme mainly affects the inner part of the fiber. Plasma treatment did not affect mechanical properties related to the handling of fabrics. The handling test showed increased extension at maxmum load(EM), tensile energy(WT) with decreased tensile resilience (RT), and the fabrics became softer but resilience decreased slightly with enzyme treatment. The bending recidity(B), hysteresis of bending moment(2HB), and hysteresis of shear force at five degrees(2HG5) decreased, however, shear stiffness(G) increased. I knew the plasma pre-treatment made fabrics softer with lower koshi(stiffness). The handling of plasma pre-treated fabrics was better than that of enzyme-treated fabrics. When we pre-treated fabrics, the handling test showed decreased coefficient of friction(MIU), geometrical roughness(SMD), while the surface of fabrics became smoother and numeri increased. Even though compression resilience(RC) increased, fukurami(bulky property) and compressive elasticity, decreased due to the linearity of compression-thickness curve(LC) and compression energy(WC).

In this study, the mechanical properties related to the fabric appearance of well being functional bamboo knitted fabric before and after loess dyeing were evaluated. The mechanical properties of fabrics were measured by KES-F system, that is, shape retention, draping, wrinkle recovery, compression property, and surface properties, and total hand value of three types of knitted fabric, 100% bamboo, 100% cotton, and bamboo / cotton blend (60 / 40) were evaluated before and after loess dyeing. As a result, it was found that appearance density, shape retention, and drape coefficient of cotton knitted fabric were greater than those of bamboo knitted fabric. After loess dyeing, shape retention and drape coefficient, wrinkle recovery of bamboo knitted fabric improved and WC/C and MMD/SMD decreased. According to THV, the hand of bamboo/cotton blend knit is the best among three samples by compensation the weak properties of the two fiber. Therefore, loess dyeing seemed to be a good method for improving shape retention and hand value of 100% bamboo and bamboo blended fabric.
