To improve rubbing fastness of the printed fabrics, the binder polymers for Digital Textile Printing(DTP) pigment inks were synthesized with miniemulsion polymerization using various acrylic monomers, which are MMA(Methyl methacrylate), BA(Butyl acrylate), and Self-crosslinking monomers, such as NEA(N-Ethylol acrylamide) and MAA (Methacrylic acid). The acrylic monomer compositions were varied when synthesizing the binder polymers and their particle size distributions, average molecular weights, and Tgs were investigated. The prepared binder polymers were applied to prepare Cyan, Black, Yellow and Magenta pigment ink for DTP and the prepared inks were used to dye cotton fabrics. Then, color strength, and rubbing fastness were also investigated to study the effect of the comonomer compositions of the binder polymer on the color strength and rubbing fastness of the resulting pigment inks.

This study examines the mordanting effect and multi functional properties of silk fabrics dyed with onion shell extracts that were mordanted with gallnut. The contents of this study are as follows. First, the optimum dyeing conditions were investigated by measuring the K/S value that depended the on dyeing conditions when silk fabrics were dyed with onion shell extracts. Second, the color, brightness, and chroma differences that appear after mordanting with gallnut were investigated by measuring the K/S and Munsell value. Third, the color fastness and antimicrobial activity were measured. When silk fabrics were dyed with onion shell extracts, the optimum dyeing conditions were a dyeing temperature of $70^{\circ}C$, a dyeing concentration of 160%, and a dyeing of time 30min. After mordanting with gallnut extracts, the K/S value increased remarkably and was larger in pre-mordanting than post-mordanting. The H value displayed yellow-red in all cases of pre and post mordanting. However, the H value was more reddish in the order of non-mordanting

In this study, synthetic fiber fabrics such as polyester, nylon 6, acrylic and acetate were dyed with indigoid vat dye. The effects of the composition of alkaline reduction, dyeing time and dyeing temperature on color strength and color fastness of the fabrics were investigated. Also the color fastnesses to wash and light of the dyed fabrics were studied. In dyeing of polyester, nylon, acrylic and acetate fiber fabrics with indigo vat dyes, it appears that these fabrics have high values of K/S up to Ig/L of sodium hydroxide and 6g/L of reducing agent. Indigo vat dyeing for synthetic fiber fabrics was verb fast, and lead to dyeing equilibrium within twenty minutes. The K/S values of dyed fabrics did not changed in dye concentration more than 10% o.w.f.. Synthetic fiber fabrics dyed with indigoid dyes had bad light fastness.

This study was performed to determine the effect of structural characteristics of selected wool fabrics on mechanical and thermal properties. 52 wool fabrics, including 18 plain woven fabrics and 34 twill and satin woven fabrics were used as samples woven with various weft density for the study. Several physical characteristics such as mechanical properties, keeping warmth ratio of wool fabrics were measured. Data analyses including 1) analysis of tactile and thermal comfort sensation were performed. the following were obtained from the results: The main factors affecting keeping warmth ratio were thickness and bulk density. The keeping warmth ratio of samples increased with increasing thickness and decreasing bulk density of samples. In addition, coefficient of friction of the samples increased with keeping warmth ratio of samples. The above results show that wearing sensation and comfort properties of fabrics are changed depending on the end-use, and thus, above results can be used to manufacture of fabrics for specific end-use with high comfort properties.

In order to study the effect of mordanting on silk fabrics treated with tannin, those fabrics were treated with Al, Cu, Cr, Fe, Sn by pre and post mordanting. It was studied about color change, weighting effect, dgree of photodegradation by pre and post mordanting. The results are as fallows ; 1. On the addition of mordants into mimosa and tannic acid solution, &{\lambda}_{max}& of the former was slightly blue-shifted, on the other hand, &{\lambda}_{max}& of the latter was obviously Red-shifted. 2. In case of Cu, Cr, Pre mordanting, weighting effect were appeared. Weighting effect of silk fabrics treated with Tannic acid increased higher than mimosa by mordanting. 3. In color change, Silk fabrics treated with Mimosa and Tannic acid generally changed to red direction and fabrics treated with tannic acid changed to yellow direction by pre and post mordanting. 4. In the photodegradation, the degree of photodegradation on mordanted fabrics increased. Its degree was slack in Cu, Cr, Post mordanting. On the other hand, Al, Fe, Sn were greate. Silk fabrics treated with Mimosa and Tannic acid got inhibiting effect on photodegradation.

The tensile properties of Poly(trimethylene terephthalate, PTT) $1{\times}1Rib$ knitted fabrics were experimentally studies, and the specimens has $1{\times}1$ rib stitched structure which are weft knitted fabrics with various lengths of loop. The $1{\times}1$ rib weft knitted fabric showed larger tensile linearity, tensile energy and tensile resilience in the direction of courses. The tensile properties increased with increasing the loop density in all directions, and perfectly increased with the course directions than the wale directions.

The purpose of this study was to investigate the dyeability and antibacterial activity on wool fabric dyed with cochineal at variable dyeing conditions. Al, Cr, Fe, Cu and Sn were used as mordants and adsorption was compared with different mordanting methods. The optimum dyeing conditions of wool fabrics were dyeing concentration 2.0%(o.w.s), dyeing temperature $60^{\circ}C$, pH 3 and dyeing time 30 minutes. The pre-mordanting method was preferred for Al and Cr, and the post-mordanting one was preferred for Cu, Sn and Fe to achieve better dyeing. The optimum mordanting conditions of wool fabrics dyed with cochineal were mordanting concentration of 1%(o.w.s), mordanting temperature $60^{\circ}C$, and dyeing time 30 minutes. Wool fabrics dyed with cochineal showed a little antibacterial activity, but it was increased by Cu and Sn mordanting. The light fastness and perspiration fastness of wool fabric treated with cochineal were improved by mordanting.
