As a part of the study for the materials development of compound feelings, therefore, this study investigated into the effects of the colors of warp and weft on the overall colors of fabrics, along with the visual changes of colors by the measuring angle of both warp and weft, by means of cross-dyeing of cotton/PET union fabrics. First, the dyeing of cotton and PET fabrics individually with the same color, the dyeing of PET fabrics followed by that of cotton fabrics resulted in a small difference in color than the dyeing in the reversed order. Second, in the case of the dyeing of cotton/PET union fabrics with the color of one fiber fixed and that of the other in ten colors, the color of cotton fiber, which is warp, gave much influence. In addition, the color change was remarkable among complementary colors, while it was negligible among adjacent colors. Third, in the case of dyeing of cotton/PET union fabrics with the color of one fiber fixed and that of the other in ten colors, the results were different by the measuring angle. When PET was fixed in green and cotton was dyed in ten colors, color-deepening was observed by the inclination in the direction of warp and weft without the dominance over all colors like cotton. When cotton was dyed in red and PET in ten colors, the color of PET appeared dimly in the horizontal case by the direction of the light, and red appeared as inclined in the direction of warp and weft. This is because of the dominance of cotton color over the overall color, since the density of cotton fiber, the warp of union fabrics, is higher than that of PET, the weft. Thus, this is to be considered in the selection of the warp's color. In view of the above results, the color changes are outstanding when the color of warp dominates the overall color and when the colors of warp and weft are complementary, in comparison with the case when the colors are adjacent. The colors also change by the measuring angle.

This study investigated into the effects of the colors of warp and weft on the overall colors of fabrics, along with the visual changes of colors by the measuring angle of both warp and weft, by means of cross-dyeing of cotton/PET union fabrics. First, the reflectance of polyester is higher than that of cotton over the whole wavelength. Second, the dyeing of polyester uses the disperse dyes and that of cotton uses fiber-reactive dyes, the differences in the features of dyes and the reflectance of fabrics cause the same colors to be perceived different by the angle of observation. Third, the dyeing of cotton and PET fabrics individually with the same color revealed that the dyeing of cotton and PET fabrics in one bath resulted in a small difference in colors between the two fabrics than the separate dyeing in two bathes. In the case of one bath, the dyeing of PET fabrics followed by that of cotton fabrics resulted in a small difference in color than the dyeing in the reversed order. Fourth, when cotton/PET union fabrics were dyed in ten colors, the difference in colors between the two fabrics was small; and due to the difference in the density of warp and weft of union fabrics, some difference was detected in comparison with the results of separate dyeing of cotton and PET fabrics in one bath. The latter did not produce the changes in color which was recognizable with the naked eyes. Fifth, when cotton/PET union fabrics were dyed in ten colors, any color change was not observed by the measuring angle, and the inclination in the direction of warp or weft resulted in the tendency of color-deepening. In the measurement of the latter, the inclination in the direction of weft resulted in the higher color-deepening than that in the direction of warp, due to the influence of weft.

Two reactive disperse dyes having $\alpha$-bromoacrylamide or acrylamide group were synthesized and their dyeing properties were compared with a disperse dye. Dyeing properties of reactive disperse dyes were strongly influenced by the chemical structure of reactive group. The amount of absorbed reactive disperse dye containing $\alpha$-bromoacrylamide group on polyester fiber was less than the disperse dye, and that on nylon fiber was much higher. When polyester and nylon fiber were simultaneously dyed in a dye pot, nylon fiber absorbed the reactive disperse dye more than polyester fiber. The reactive disperse dye having acrylamide group could reduces difference in color depth to a large extent, but the application of carrier or variation of dyebath pH were not sufficient for giving the same color depth to both fibers. The N/P union fabric could be dyed with the reactive disperse dye and its wash fastness were good to excellent.

In the Previous studies, we reported about the synthesis of poly[3-methylence-3-methylenesodiumbisulfite-bis(4-hydroxypheny)sulfone] (PMSBPS) and their effect on the staining of direct dye on nylon in the dyeing of nylon/cotton union. The results showed that PMSBPS have good staining resist effect on nylon in the dyeing of nylon/cotton union. In this study, the staining resist effects of PMSBPS in varied dyeing process and method were investigated, and the fastness to washing, light, and rubbing of the deed N/C unions was tested. The results are as follows ; 1. In the two bath two step method, the staining of direct dye on nylon was decreased with the concentration of PMSBPS, and the fastness to washing, light, and rubbing of the dyed N/C unions were increased by addition of PMSBPS. 2. In the one bath two step method, optimun concentration of PMSBPS was 4% 0.w.f..

A series of poly[3-methylene-3'-methylenesodiumbisulfite-bis(4-hydroxyphenyl) sulfone] (PMSBPS) was synthesized by the reaction of bis-(4-hydroxyphenyl)sulfone(BPS), formalin, and formaldehyde sodium bisulfite(FSB), and their effect on the staining of direct dye on nylon in the dyeing of nylon/cotton union fabric was investigated. PMSBPSes have good staining resist effect on nylon in the dyeing of nylon/cotton union. Prolonged reacting time between BPS and formalin is effective in improving the staining resist of final PMSBPS. Too many sulfonic acid groups than necessary in the PMSBPS increase the staining of nylon, presumably by increasing the solubility of PMSBPS. Staining resist effect of PMSBPS was evident in the measurement of color diffence of dyed goods.

The purpose of this study is searching the Elm-Bark dyes' dyeability and antibacterial activities according to the dyeing time, pH, a mordant and the method of mordancy. We used two kinds of Elm-Bark dyes which's extracted by the Electrolytic reduction water and Distilled water. Silk fabric and Cotton/nylon union fabric was used for this study. The results are as follow. K/S value is increased according to the dyeing time and the suitable pH level is pH 3. Dyeability is good with Iron(II) sulfate$(FeSO_4\cdot{7H}_2O)$ on the pre-mordancy and Potassium dichromate$(K_2Cr_2O_7)$ on the post-mordancy. The Elm-Bark dyes by the Electrolytic reduction water has good colorfastness more than by the Distilled water. Antibacterial activities is excellent and the ratio is over than 99.5%.

New scouring agent which was stable up to 50% NaOH 350g/l has been developed for simultaneous CPB/silket treatment of N/C union fabric. The physical and dyeing properties of N/C union fabric treated with new scouring agent were measured. Fabric scoured and Mercerized by one bath CPB/silket process showed almost the same degree of Mercerization and K/S value with two bath process.

본 연구의 목적은 트리아세테이트와 흡한속건성 PET 합연사로 구성된 복합직물의 염착량 증진 및 동일색상 염색(union dyeing)을 위한 최적 혼합염색 조건을 찾는 것이다. 이를 위하여 E-type 분산염료(C.I. Disperse red 50)와 S-type 분산염료(C.I. Disperse red 92)를 혼합하여 1욕 혼합염색으로 염색온도, 염색시간, 염료의 혼합비율에 따른 염색직물의 흡진율, 염착율, 색상 및 색차를 측정하였다. 혼합염색의 염착평형은 $100^{\circ}C$에서 일어났으나 염색된 직물의 K/S 값과 겉보기 색상을 비교해보았을 때 트리아세테이트와 흡한속건성 PET의 색이 동일한 색으로 발현되는 온도는 $120^{\circ}C$임을 확인하였다. 염색 시간 증가에 따른 혼합염료 흡진율과 염착량의 변화는 크게 나타나지 않았으나 염색시간이 길수록 그리고 혼합염료를 사용할 경우 균일한 색상을 얻을 수 있었다. E-type에 S-type염료의 혼합비율을 적절히 조절하여 혼합염색 하면 단독염색 보다 E-type 염료의 색상과 차이 없이 염착량을 증대시킬 수 있었다.
