Dyeing and color fastness properties of a reactive disperse dye containing an acetoxyethylsulphone group on PET, Nylon, silk and N/P fabrics were examined. The reactive disperse dye exhibited almost the same dyeing properties on PET fabric as a conventional disperse dye except the level of dye uptake. The most appropriate pH and dyeing temperature for the dyeing of Nylon fabric were 7 and $100^{\circ}C$ respectively. The build-up on Nylon fabric was good and various color fastnesses were good to excellent due to the formation of the covalent bond. Application of the reactive disperse dye on silk fabric at pH 9 and $80^{\circ}C$ yielded optimum color strength. The rate of dyeing on Nylon fabric was faster than that on PET fabric when both fabrics were dyed simultaneously in a dye bath, accordingly color strength of the dyed Nylon was higher. The reactive disperse dye can be applied for one-step and one-bath dyeing of N/P mixture fabric with good color fastness.

In order to dye nylon/cotton blended fabrics in solid colors with only acid dyes, a hetero-bifunctional bridge compound (DBDCBS) was examined. The bridge compound was designed to react only onto cotton fabrics first, on which amino-containing acid dyes react later by covalent bonding. By the effect of DBDCBS, amino-containing acid dyes exhibited high affinity toward the cotton fabrics. From the dyeing properties examined at various conditions, the optimum dyeing was decided at pH 4 and $100^{\circ}C$. Consequently, the solid color was obtained on nylon/cotton blended fabrics in one bath dyeing process using only acid dyes. The DBDCBS did not show any negative effect on nylon side in terms of dyeing and physical properties.

The textile finishing methods utilizing chitosan have been mostly focused on the applications in the improvement of the dyeing of cotton fabrics, or the improvement of hand of the cotton or wool fabrics. On the other hand, it Is difficult to find the application examples in the synthetic fiber fabrics including polyester and nylon fabrics. The aim of this study is to improve the stiffness and the poor wash fastness of the fabrics treated only with chitosan. We tried to improve the softness by employing chitosan and polyurethane mixture solution and to prevent the detachment of the chitosan from the fabric. The treatment was applied to cotton, polyester, and nylon fabrics. The change of the properties of the treated fabrics were investigated. The optimum finishing condition was sought by changing the mixture ratio of the chitosan/PU(polyurethane) solutions. The adjusted ratios of the chitosan/PU solutions were 1 : 0, 1 : 0.25, 1 : 0.5, and 1 : 2 during the mixture solution preparation. Using the KES(Kawabata Evaluation System), the physical and mechanical properties of the finished fabric specimens were analyzed, and hand values of the specimens were calculated through the use of translational formulas. According to the chemical composition of the fibers, chitosan solution or chitosan/PU mixture exhibited wide range of coating effect. Since the chitosan acid solution has high polarity, the bonding force with the cotton fibers is high. By the appropriate addition of PU in the chitosan treatment of cotton, KOSHI and HARI values of the fabric improved. The air permeability of the chitosan/PU treated cotton fabric specimen improved, resulting in the highest value at the mixture of chitosan : PU=1:0.25.

Chitosan treatment of textile fabrics has been studied to improve fabric characteristics and functions. Natural dyestuffs have been more actively employed in environment-conscious finishing products. In this study, chitosan treated cotton and nylon fabrics were prepared for dyeing with a few natural dyestuffs. These were Caesalpina sappan, Gardenia jasminoides, and cochineal in the form of powder. Hand-related physical and mechanical properties and luster characteristics were examined using the KES-FB series instruments and a set of luster measuring equipment. The chitosan treatment seemed to be more effective in terms of increasing stiffness for cotton fabric. Since cotton fibers have more -OH groups in the molecules, they provide more linkage sites with the chitosan than the nylon 6 fibers do.

Polyaniline(PAn)-nylon 6 composite fabrics were prepared by immersing the nylon 6 fabrics in 100% distilled aniline for specified diffusion time and drawn out. Then the excess aniline on the fabric surface was blotted and successive polymerization was initiate by immersing them into oxidant and dopant solution for in situ polymerization of polyaniline. Consequently highly conductive PAn-nylon 6 composite fabrics could be obtained and the conductivity reaches as high as 10-2 S/cm. The maximum conductivity was obtained when the fabric was immersed in 100% aniline at 4$0^{\circ}C$ for 3hours and polymerization was proceeded in 0.25M ammonium peroxydisulfate solution at 5$^{\circ}C$ for 1hour.

It was the purpose of this study to investigate the effect of chitosan treatment and mordanting on the air-permeability, fastness of the dyestuff to washing, fastness of the dyestuff to light, and antimicrobial effect of cotton and nylon fabrics dyed using Rhusjara ica. In the dyeing experiment, examinations were made on the difference between the chitosan treated fabrics and chitosan untreated fabrics, and on the difference according to the type of mordanting agents and the mordanting methods. Dyeing was carried out for the chitosan treated and untreated fabrics under the conditions of non-mordanting and Al, Sn, Fe mordanting. As a result, due to the dye-uptake of the dyestuff component of the Rhusjara ica, the air-permeability values decreased considerably. And due to the action of the mordanting agents, the air-permeability decreased also. The air-permeability decreased more conspicuously in the case of the dyestuffs uptake to the chitosan components than in the case of the dyestuffs uptake to the cotton fibers or nylon fibers. Nylon dyed fabric exhibited better wash fastness than the cotton dyed fabric. As the number of washing increased, the color of the cotton fabric specimens and nylon fabric specimens, dyed using Rhusjara ica, shifted toward yellowish. The light fastness values were in the range of grade 1${\~}$2, which were very inferior. The light fastness values did not improve according to the mordanting or to the chitosan treatment. In the case of chitosan untreated fabrics dyed using Rhusjara ica, the growth rate of the bacteria promoted, on the contrary, compared to that of the control white fabric.

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.
