The purpose of this study is to investigate the dyeability, and the hand of soybean/cotton blended fabric after dyeing with natural and synthetic dyes. Soybean/cotton blended fabrics dyed with extracted solution from turmeric, sappan wood, gardenia and synthetic dyes(weak-acid dyes, reactive dyes, direct dyes). The hand value of soybean/cotton blended fabrics dyed with 6 different dyes was measured using Kawabata Evaluation System. The results are as follows; 1. The K/S value of the soybean/cotton blended fabric dyed with sappan wood extracts was the highest. 2. The color fastness of the soybean/cotton blended fabric dyed with reactive dyes was excellent. The fastness to the light of the same fabric was much better than the other fabrics. 3. Linearity of load-extension and tensile energy of the soybean/cotton blended fabric dyed with sappan wood extracts showed very high. Shear stiffness of the soybean/cotton blended fabric dyed with weak-acid dyes was much higher than that of fabric of dyed with reactive dyes. Bending property of the fabrics dyed with natural colorants(sappan wood, gardenia) showed very high, but that the fabric dyed with reactive dyes was very poor. 4. In the primary hand value, stiffness and anti-drape stiffness of the fabric dyed with weak-acid dyes showed the highest. Fullness and softness of the fabric dyed with weak-acid dyes showed very low.

The dyeing of poly(trimethylene terephthalate)(PTT)/silk mixture fabrics can be accomplished by a two bath dyeing method with separate application of the disperse dyes on the PTT, reduction cleaning of the stained silk and then dyeing the silk with the acid dyes, or by one bath dyeing method with mixed dye ranges, possibly followed by a cleaning treatment. The two bath dyeing method has the advantage of better results with respect to dry cleaning fastness properties thanks to the possibility of an intermediate reduction clear. On the other hand, as compared with the two bath dyeing method, one bath dyeing method with a mixed dye range permits rapid and more reproducible dyeing, without the risk of great difference with respect to the shade of the strike on both substrates as well as savings of time, energy and water usage. This study was carried out to investigate dyeing characteristics of PTT/silk mixture fabrics with disperse dyes/acid dyes by one bath dyeing method in comparison with two bath dyeing method in the interests for rationalization of the dyeing process.

Low temperature dyeing properties of wool with reactive dyes and acid dyes were investigated for the feasibility study of their application to hair dyeing. The low temperature(30℃, 40℃) dyeing achieved light depth of shade in wool dyeing and reactive dyeing exhibited relatively higher color strength and chroma values than acid dyeing. Leveling agent slightly improved the levelness of the wool dyeing and the leveling properties of dyed wool at low temperature were good to excellent, irrespective of the dyes applied. Color loss during the repeated shampooing was in the range of 9.6~22.2% for reactive dyes and -7.4~31.5% for acid dyes and in some cases, the color fastness to shampooing was reasonable level. The overall experimental results showed that the application of low temperature wool reactive dyeing to hair dyeing is sufficiently feasible in terms of dyeability and color fastness to shampooing.

Of the various types of dye that can be used to apply polyamide fibers, acid dyes and pre-metallised acid dyes are great in use so far. However, since these acid dyeings suffer from dye loss during laundering, recourse to an aftertreatment is usually necessary to achieve adequate fastness to washing. In the case of reactive dyes, the characteristically high washfastness of dyeings comes with the concomitant advantages of brightness and low environmental impact. Despite the obvious advantages, the commercialization of reactive dyes for polyamide fibers has not gained widespread success. In this context, the rewards for approach are likely to be considerable. Heterobifunctional reactive dyes were applied to polyamide fibers using various conditions. Optimum conditions and fixation were determined. The forms in which the vinylsulphone and hydrolyzed moieties were examined using HPLC-Mass. In addition, it was found that the extent of the washfastness secured, in terms of both change in color and staining of adjacent multifiber was being acceptable.

PET fabrics were cationized via photografting under continuous UV irradiation with a cationic monomer. The grafted PET was dyed with three acid dyes. Effect of dye concentration, dyeing time, temperature and pH on acidic dyeing of the cationized PET fabrics was assessed to find optimal dyeing condition. The cationized fabrics was successfully dyed at $75^{\circ}C$ under pH 5.5. However the dyeing sites of the grafted fabrics were nearly occupied above 5%owf dye concentration and the rapid exhaustion of the anionic dyes was observed. The dyeability of the cationized PET fabrics was increased proportionally with increasing percent grafting because of the introduction of ionic attraction between quaternary ammonium groups and acid dyes. Lower dyeability both at alkaline and pH 3 condition attributed to negative zeta potentials of the grafted fabrics and the reduced charge of the acid dyes respectively.

Nylon 6 ultramicrofiber(UMF, monodenier 0.074d) and regular staple fiber(monodenier 2.05d) were dyed with acid and disperse dyes to investigate the effect of the difference of the fiber fineness. Also X-ray diffraction pattern, birefringence, DSC thermogram, moisture regain and water absorption of these fibers are measured. The dyeing rate of nylon UMF with acid dyes is increased compared with that of regular fiber, but not increased for disperse dyes. Also the saturation dye uptake of UMF with acid dyes is higher than that of regular fiber, while it is unchanged for disperse dyes. The moisture regain of UMF is similar to the regular fiber, whereas the water absorption of UMF is two times th그n that of the regular fiber. The crystallinity percentage of UMF is higher than that of regular fiber.

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.

In this research work, synthesis of sugarcane bagasse/zinc aluminium biocomposite and apple peel/zinc aluminium biocomposite and their application for removal of Reactive Red-241 and Acid Orange-7, respectively, was studied using various parameters. At pH 2 the sorption was the highest for both dyes. The trend showed that the dye sorption declined by decreasing the biocomposite dose and enhanced by increasing the dye concentration and temperature. Equilibrium was achieved at 60 minutes for Reactive Red-241 onto sugarcane bagasse/zinc aluminium biocomposite and 90 minutes for Acid Orange-7 onto apple peel/zinc aluminium biocomposite.The research data was good fitted to pseudo-2nd-order kinetic model and Langmuir isotherm. FT-IR analysis was used to confirm the biosorption of the selected dyes at the surface of biosorbent through various binding sites. Surface morphology modification of both biocomposites before and after biosorption was inspected through SEM. Crystallinity of biocomposite was examined through XRD analysis. It was implied that sugarcane bagasse/ zinc aluminium biocomposite and apple peel/ zinc aluminium biocomposite are good adsorbents for dyes elimination from aqueous solutions.

The dyeing characteristics of Dylon hand dyes on the cotton & silk fabric were studied, and the fastnesses of Dylon hand dyes were compared with those of direct & acid dyes. The results are as follows. 1. Dye adsorption of Dylon hand dyes increased as the concentration of dye increased. 2. Dye adsorption was increased as treatment time increased, and reached to eqilibrium after forty minutes treatment. 3. The temperature at mixiumum adsorption was 6$0^{\circ}C$, in the range of lower temperature than 6$0^{\circ}C$ color was changed, in the range of higher temperature adsorption of dye was decreased. 4. Dye adsorption was increased in direct proprotion to NaCl concentration and reached to equilibrium. But NaCl concentration of even and maximum adsorption was 5%. 5. Wash fastness of Dylon hand dyes was better than direct & acid dyes, but light fastness was worse.
