견의 저온염색용 조제(K-1)를 사용하여 염료 농도, 염욕의 pH, 염색시간에 따른 염색속도를 구하여 이 저온염색용가 염색에 미치는 영향을 분석한 결과를 다음과 같이 요약한다. 1. pH 7에서 K-1의 농도가 증가할수록 무첨가구에 비해 흡진율은 증가 하였으며, K-1의 농도가 3% o.w.f. 이상에서는 증가의 경향이 둔화되었다. 2. pH 5에서도 무첨가보다 K-1의 첨가구에서 높은 흡진율을 보였으며, pH 7의 5$0^{\circ}C$ 첨가구가 pH 5, 5$0^{\circ}C$의 무첨가구보다 확산성은 높게 나타났다. 3. 염료 농도별로 볼 때 pH 7과 pH 5에서 모두 K-l 첨가구에서는 무첨가구보다 흡진율이 클 뿐만 아니라 염료 농도에 따른 흡진율 감소가 적게 일어났다.

The conventional one bath exhaust dyeing system of nylon]/cotton blends with acid dye/direct dye involves a lot of neutral salt which affect dyeability of acid dyes. Because of conventional one bath exhaust dyeing system of nylonl/cotton blends with acid dye/direct dye needs acid dyes adjusted at a neutral liquor, suitable acid dye is limited. To improve dyeing property of nylon/cotton blends, cotton component was pretreated with cationizing agent containing chlorohydrine group in aqueous solution of sodium hydroxide. This study was carried out to investigate dyeing possibilities of nylon/cationized cotton blends with acid dye/direct dye in a non-neutral salt dyebath by one bath two step method. The concentration of direct dye was 1.0%, 0.7%, 0.3%o.w.f. respectively at a non, 1%, 3%owf of reserving agent for being almost equal color strength between nylon and 3% cationized cotton when nylon/3% cationized cotton blends was dyed with acid dye/direct dye at concentration of acid dye(1%o.w.f.) by one bath two step method.

in order to overcome disadvantage of the conventional two bath dyeing method of polyester/cotton blends, it had prompted significant effort to the development of the one bath dyeing method which can accomplish sayings in time, energy and water usage. Also, when dyeing polyester/cotton blends by the one bath dyeing method, the high salt concentrations needed for the reactive dye can cause particles of disperse dye, used for the polyester component, to aggregate. A supplementary problem that can occasionally be happened is the change of hue that occurs on dyed polyester in an alkaline dyebath. To improve dyeing property of polyester/cotton blends, cotton component was pretreated with epichlolohydrine-trimethylamine hydrochloride in aqueous solution of sodium hydroxide to produce a cationized cotton that can be dyed under neutral conditions with reactive dye in a non-electrolytic or il little electrolytic dyebath. The one bath dyeing method of polyester/cationized cotton blends with disperse dye/reactive dye mixture resulted in a satisfactory dyeing property and color yield in comparison with ordinary two bath dyeing method.

Six nano disperse dyes were prepared using corresponding O/W nanoemulsions which were obtained with sodium laurylsulphate and caprylic triglyceride. The average particle size of the dyes prepared were in the range of $110{\sim}130nm$. Exhaust dyeing using nano dyes resulted in low exhaustion yields of $17{\sim}26%$ on regular polyester fiber and $28{\sim}38%$ on ultramicrofiber polyester. The observed low exhaustion yields of nano disperse dye can be explained by the solubilization of dye particles into surfactant micelles as well as the high stability of the nanoemulsions, these might reduce the capacity of dye uptake onto the fibers. However, higher K/S values of dyeings with nano dyes on ultramicrofiber sites compared to those on regular polyester sites suggested their potential to be more efficient dyes for finer denier microfiber polyesters.

This research aimed at scrutinizing the comparative dyeability of some disperse dyes at low temperature on ultra-microfiber polyester, islands in the sea type (0.05 denier), which has claimed utmost fastness and improved uptake of dyeing. Comparisons of dyeability, such as rate of dyeing and color depth, on ultra-microfiber polyester were evaluated by H.T. exhaust dyeing method and followed by the test of rubbing fastness. To achieve high wet fastness, some commercial disperse dyes, Terasil WW and Megacron dyes, which have been recently launched for excellent wash fastness, have been examined compared with conventional disperse dyes, C.I Disperse Red 167 and C.I Disperse Orange 30.

This research aimed at scrutinizing the dyeability of some solvent dyes on polyester and their light fastness to be exploited as a breakthrough in light fastness where utmost fastness is required such as ultramicrofibers and industrial markets. Dyeability on polyester was mainly evaluated by HT exhaust dyeing according to the general procedure. Light fastness has been tested by a preliminary UV test followed by HT xenon test in compliance with standard SAE J1885, 224 KJ. Fading has been determined quantitatively by evaluating the shade deviation and the strength difference between unexposed and exposed samples by means of CIELab values.

Jacquard floor covering could be prepared from low-melting/regular sheath-core hybrid polyester, where the fiber is dyed in yarn state. With regard that the expected high shrinkage of the hybrid polyester in water makes problems in yarn dyeing, low-temperature dyeing properties of the hybrid polyester were studied. The rate of shrinkage of low-melting hybrid polyester exceeds 9% in hot water above $90^{\circ}C$, at such condition, cheese yarn dyeing is very difficult. Although disperse dyes exhaust in a relatively high speed on low-melting hybrid polyester, diffusion of these dyes to the core regular polyester was extremely slow under $90^{\circ}C$. Foron Blue E-BL 150, an anthraquinone E-type disperse dye, showed appreciable diffusion after 48hrs dyeing at $90^{\circ}C$. The fastness to rubbing and drycleaning were improved by one grade after reduction cleaning.

In this study, 12 azo disperse dyes based on phthalimide were synthesized including their precursors. The chemical structures of the dyes and the corresponding precursors were analyzed by the GC-MASS, $^1H$ NMR spectra and elemental analysis. The dyeability on PET, such as step dyeing and build-up properties and color fastness were examined using conventional exhaust dyeing procedures.

Some phthalimidyl azo dyes containing N,N-diethyl or N,N-di($\beta$-methoxycarbonylethyl) group have been attempted to apply onto two kinds of polyurethane based materials and rationalize their dyeability and fastness comparing with those of some commercial disperse dyes. Phthalimidyl azo dye showed 66~98% of exhaustion yield at $120^{\circ}C$ by a conventional exhaust dyeing method. The dyeings were found to have a higher wash fastness with both fabrics in comparison with those of commercial dyes which indicates lower thermomigration and efficient alkali clearable properties of phthalimidyl ring and/or diester group during post-dyeing process.
