On the whole the various medium colors were developed by repeat dyeing with different colorants after dyeing with one colorant in case of natural dyeing. In this study, in order to obtain various colors on wool fabrics with Gardenia and Sappan wood colorants, pre-mordanting and combination dyeing were carried out. Gardenia and Sappan wood used as natural colorants for combination dyeing showed good miscibility in dye bath, Metal compounds containing alum, copper and iron were used for pre-mordants. The various medium colors such as yellow-red were obtained according to various metal compounds for pre-mordants and various mixing portion of these natural colorants. The surface reflactance spectra and color characteristics of wool fabrics by mordanting and combination dyeing were investigated.

On the whole the various medium colors were developed by repeat dyeing with different colorants after dyeing with one colorant in case of natural dyeing. In this study, however in order to obtain various colors on silk fabrics with natural dyes, pre-mordanting and combination dyeing were carried out. Metal compounds containing alum, copper and iron were used for pre-mordants. Gardenia and Sappan wood were used as colorants for combination dyeing. In combination dyeing of Gardenia and Sappan wood, these two natural colorants showed good miscibility in dye bath. The various colors were obtained according to various metal compounds for pre-mordants and various mixing portion of Gardenia and Sappan wood.

In one bath dyeing system of silk/cellulose acetate fiber blend fabric with acid /disperse dyes, adsorption behavior of acid dyes and disperse dyes on silk and cellulose acetate fabrics were examined. In the dyeing of cellulose acetate with C. I. Disperse Red 19(Red 19) and C. I. Disperse Red 60(Red 60) at 8$0^{\circ}C$ and 10$0^{\circ}C$, dye uptake with Red 19 was higher than that with Red 60. When the silk/cellulose acetate dyed with Red 19 and Red 60 at 10$0^{\circ}C$, dye uptake on cellulose acetate was influenced by affinity of the dye to the silk fabric dyed together. When the silk/cellulose acetate dyed with Blue 80/Red 19 and Blue 80/Red 60 at 10$0^{\circ}C$, color of cellulose acetate dyed with Red 19 and Red 60 was not influenced by Blue 80 but silk dyed with Blue 80 was influenced by Red 19 and Red 60. Interrelation of K/S value and Munsell value was scarcely any but showed the change tendency of K/S value.

Dyeing properties of cow leather was investigated with Tumeric powder. The effects of dyeing conditions, mordanting conditions, color change, and color fastnesses were studied. The results were as follows. The dye uptake increased as dye concentration, dyeing temperature, and bath ratio increased. In the effect of dyeing time, the highest dye uptakes showed at 20 minutes and decreased after that point. Pre mordanting was more effective than the post mordanting, and the dye uptakes improved all mordanted fabrics. The highest K/S values showed in pre-Al sample, and the lowest K/S values showed in post-Cu one. The values of Hunter on the samples were more changeable $L^*$ and $b^*$ than $a^*$, and all samples showed Yellow color in Munsell value. But the mordanting methods and mordanting agents were not significant in the color changes. The light fastness of dyed samples showed 1 grade, the dry cleaning and abrasion fastnesses did not improved except post-Fe wet sample.

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.

In one bath dyeing system of silk/PET fiber blend fabric with acid/disperse dyes, adsorption behavior of disperse dyes and acid dyes on silk and PET fabrics were examined. In the dyeing of PET with C.I.Disperse Red 19(Red 19) and C.I.Disperse Red 60(Red 60) at 10$0^{\circ}C$(carrier dyeing) and 13$0^{\circ}C$, dye uptake with Red 60 was higher than that with Red 19. When the silk/PET dyed with Red 19 and Red 60 at 10$0^{\circ}C$(carrier dyeing) and 13$0^{\circ}C$, dye uptake on PET was influenced by affinity of the dye to the silk fabric dyed together. When the silk/PET dyed with Blue 80/Red 19 and Blue 80/Red 60 at 10$0^{\circ}C$(carrier dyeing) and 13$0^{\circ}C$ for 60 minutes, color of PET dyed with Red 19 and Red 60 was little influenced by Blue 80 but silk dyed with Blue 80 was influenced. Interrelation of K/S value and Munsell value was scarcely any but showed the change tendency of K/S value.

In recent, development of nano fiber has been one of the most active subjects in the world. Nano fiber is defined as a ultra fine yarn with a diameter unit of $10-100\times10^{-9}meter$, which is possible to be produced by an electro-spinning technology. In this study, physical characteristics and dyeing properties of nylon 66 nano fiber were investigated. Nylon 66 nano fiber was dyed with levelling type acid dyes. X-ray diffraction method and DSC analysis were used for the measurement of the degree of crystallization. Analysis of amino end groups was also performed in order to examine a relationship between number of amino groups and its dyeing property as well as water absorption behavior. The maximum exhaustion % of dyes and dyeing rate under various dyeing conditions, such as dyeing temperature and pH in dye bath, along with build-up properties for 2 acid dyes were evaluated. It was found that the degree of crystallization of nano fiber was smaller than that of regular fiber, and amino end groups of nano fiber were less than regular fiber. Half dyeing time of nano fiber was shorter than regular fiber because of the bigger specific surface area. Effect of pH on exhaustion % was small in case of nano fiber. Exhaustion of nano fiber increased with higher concentration of dye.

Cotton fabrics dipped in cationic agent(3-chloro-2-hydroxypropyl trimethyl ammonium chloride) were irradiated with deep Ultra Violet Rays(UV), in the region of UV-C using the low pressure mercury lamp. The chemical changes of cationized cotton fabric surfaces were investigated by FT-IR analysis. The dyeabilities of the irradiated portions were investigated by dyeing with acid dyes. Deep UV(UV-C) irradiation broke O-H bonds in cotton fiber and oxidized the fibers. The dyeability of the UV irradiated portion were different from that of the portion not irradiated. Various pattern were gained from one bath dig dyeing by pattern mask. The tensile strengths of cotton fabrics were decreased in the UV irradiated portion. Washing fastness of cotton dyeings were good about 3∼4 grade and light fastness were fair about 2∼3 grade.
