  • Dyeing and fastness properties of alkali-clearable disperse dyes of diester type, which were synthesized using diazo components derived from terephthalic acid, have been studied. They had good build-up properties and showed high exhaustion on regular polyester fiber. Washing and abrasion fastnesses of dyed polyester fabrics were excellent due to the solubility of the dyes in alkaline solution. Increase in molecular weight by introducing bulky sub-stituents to the dye improved sublimation fastness, while the addition of cyano group improved light fastness as expected. Fine denier polyester fabric dyed with the new disperse dye also exhibited excellent washing fastness. The newly synthesized dye barely stained cotton fiber, and gave good washing fastness of polyester/cotton blended fabric dyed by a one-bath dyeing method.

  • Functional properties are available with sputtering. But sputtering treatment alone cannot got a good fastness performance to washing, rubbing and light. This research was objected to investigate optimum condition by sputtering on polyester through various processing conditions such as ion current and treatment time, and then various resin treated onto metal coated polyester fabrics in order to increase washing fastness of metal membrane. As the results, the optimum conditions revealed 1500 mA of ion current, 2 min of treatment time in sputter, and suitable resin concentrations were 2% of o.w.s (on the weight of solution) in resin treatment. Therefore, we could get enhanced anti-static effect and flex stiffness as well as washing fastness in sputtered polyester fabric with various resin treatment, for example, melamine and polyurethane.

  • The study with the subjects of the female consumers of the fomentation rooms in their 20s, this research made an investigation of the fomentation wear. Also, dye-fastness experiments of the wear's colors against washing and sweating were held. The following are the conclusions; 1. Survey Results of the Present Situations of Fomentation Wear Designs of the fomentation wear, 88% belonged to a T-shirt (upper clothes) and knee pants. The primary colors of the wear were in the order of gray (37.5%), white (31.3%), orange (25%), indigo (18.8%), and yellowish (18.8%). 43% of the wear companies used the same color for two-piece clothes, and 57% employed different colors for upper and lower clothes. 2. Consumers' Attitude about Fomentation Wear The key problem in the attitude to the wear, 25.9% pointed out the worries about physical exposure (like breasts and legs) owing to the improperness in designs and sizes. 32.8% of the subjects were also worried about physical silhouette exposure following sweating. The need for design improvement was felt as the subjects expressed their intention to use better fomentation wear in design and materials if the fare is higher. 3. Experimental Results of the Dye fastness of the Fomentation Wear Dye-fastness experiments by sweating appeared in the order of gray > white > pink. The results by washing were gray & white > pink. As laundry grew in number, the grade of dye fastness fell a little bit. In the fomentation environment with more laundry and more perspiration, dye fastness of the wear's colors against washing and sweating should be fully considered.

  • In this study, the dyeing properties of Phellodendron amurense on cotton and silk fabrics were evaluated to establish a scientific database of dyeing methods using natural dyes with the ultimate aim of facilitating the practical use of these dyes. The optimal thickener and dyeing concentrations depending on the thickener type were identified when dyeing with P. amurense, and the fabric color, color fastness, and antibiosis were examined for various thickeners, fabrics, and mordants. The results were as follows.: The optimal concentrations of thickeners when dyeing on cotton and silk fabrics were CMC 3% (w/w), Mayprogum 7% (w/w), and Indalka 9% (w/w). The optimal concentration of P. amurense was 25% (w/w), irrespective of the type of thickener. To maintain the hue unique to P. amurense, thickening with Mayprogum or Indalka and mordanting with Al was effective for cotton, while thickening with Mayprogum or Indalka and mordanting with Al or thickening with CMC and mordanting with gallnut was effective for silk. The dry-cleaning fastness and abrasion resistance of cotton fabrics dyed with P. amurense were excellent at the 4-5 level. Gallnut was effective for washing fastness and perspiration fastness against color degradation, and FFC was effective for light fastness. The washing fastness, dry-cleaning fastness, abrasion resistance, and perspiration fastness of silk fabrics dyed with P. amurense were excellent at level 4, except for washing and perspiration fastness, and FFC was effective for the improvement of light fastness. Dyeing cotton and silk fabrics with P. amurense thus yielded antibiosis and excellent washing fastness.

  • Generally, polyester microfiber has much greater dye uptake than that of regular ones. In spite of high dye up-take visual shade depth of dyed fabric decreases with smaller denier, which results in poor washing fastness of dyed fabric. In this study, in order to investigate the washing fastness, polyester microfiber fabric was dyed by using two type of disperse dyes and treated with 3 different reduction clearing methods. The reduction clearing methods in this study are normal alkaline reduction clearing, $N_2$ gas replacement method, and ultrasonic treatment during reduction clearing. The results were as followings ; The most important factors affecting the washing fastness of polyester artificial suede fabric were found to be the reduction clearing method, the chemical structure of used disperse dyes and the structure and denier of fibers. It was also obtained that the heat treatment of dyed fabric decreased the washing fastness due to the dye migration from inner phase to surface.

  • Dyeing and washing fastness properties of polyurethane-impregnated polyester (PU-impregnated PET), and the distribution of two disperse dyes between PET and PU film were studied to investigate the effect of PU portion to exhaustion and washing fastness. Dyeing properties of PU-impregnated PET were quite different with those of PET: PU-impregnated PET absorbed disperse dye linearly from the early stage of dyeing to equilibrium, and it exhibited excellent build-up property up to 4 %owf dyeing. The absorbed dye on PU film at early dyeing stage migrated to more substantive PET at the temperature higher than $115^{\circ}C$. The amount of exhausted dye on PET portion was larger than on PU film and the distribution ratio was $2.08{\sim}2.34$. The grade of washing fastness of PU-impregnated PET was the same as or lower by $0.5{\sim}1$ grade than PU film whose washing fastness was lower by $0.5{\sim}1$ than PET.

  • Disperse dyes having different molecular structures were prepared and their dyeing properties on PU, PET and PU-coated PET were studied. A disperse dye with common structure showed faster absorption rate into PU for its high affinity to PU at low temperature and this resulted in faster dyeing rate on PU-coated PET than on PET. On the other hand, a disperse dye having bulky structure was adsorbed into both PU-coated PET and PET at similar rate and it showed little affinity to PU in the whole dyeing temperature range. The amounts of disperse dyes eliminated from substrates by reduction clearing and washing fastness test were also measured. It was found that the disperse dye with bulky structure slipped out of PU in reduction clearing and washing fastness test in smaller quantity than the disperse dye with common structure. This phenomenon was corresponding well with the result of washing fastness test.

  • This study investigates the dyeability of soybean protein fabric after dyeing with gallut. In this study, the colorants of gallnut were extracted with boiling water at $60^{\circ}C$ and 60min. Soybean protein fabric was dyed with extracted solution from gallnut according to concentration, temperature and time. After dyeing with gallut solution, dyeability (K/S) was obtained by CCM observation. Al, Cu and Fe were employed as a mordanting agents. Various color changing were produced by the interactions of mordants that were different from soybean protein fabric; however, Al mordant was not indicated as a variable color change. Fastness to washing and light were also investigated. Consequently, the dyeability of the soybean protein fabric dyed with gallut showed reasonable results at 100% o.w.f, $90^{\circ}C$, for 60min. Fastness to washing according to concentration indicated good result as more than grade (4-5) in general. Fastness to light was almost the same compared to fastness to washing at all concentrations. Fastness to washing according to mordants indicated good grade (4) in principle at Al, Cu, and Fe; in addition, fastness to light indicated a good grade too. Fastness to light also indicated the highest dyeability at Fe mordant. This study shows that gallut is a reasonable dyestuff to soybean protein fabric and that it is possible to manufacture a variety of products that use soybean protein fabric.
