Dyeing fabric weaved with two or more kinds of fiber in different section has various dyeing interactions caused by different material properties of them. Newly developed knit fabric was used in this study. It composited by two different blocks, each block is included PET fiber and CDP fiber separately. Build-up properties with cation dyes and disperse dyes were good having average 83% of dyeing exhaustion yield on 5% o.w.f. dye concentration. As depending on dyeing methods, there were not showed direct interaction between cation dyes and disperse dyes. This result could be considered their different dyeing mechanism. Compatibility was best in S-type disperse dyes investigated their critical absorption range as $120^{\circ}C{\sim}130^{\circ}C$. Wash fastness was generally good in most dye.

The optical and physical properties of alkyl-substituted anthraquinoid dyes were investigated in terms of dyeing of pure polypropylene fiber. The length of alkyl substituents of the dyes did not affect the molar extinction coefficient and maximum absorption wavelength of them. The use of a double-tailed cationic surfactant, didodecyldimethylammonium bromide(DDDMAB), could make the hydrophobic dyes dispersed in water effectively. As the amount of DDDMAB increased, the average particle size of dye dispersion decreased. Maximum color strength of the fabrics was shown in the case that 1.5 molar ratio of DDDMAB was used. As for the fastness properties, commercially acceptable result was obtained in general.

수용액으로부터 3개 양이온 염료(메틸렌 블루 MB, 중성래드 NR, 녹공작석 옥살산염MG)를 제거하는 Maghnia 점토의 흡착제로서의 가능성을 알아보기 위해 접촉시간, pH, 초기 염료 농도, 흡착제 사용량등을 변화시키면서 조사하였다. 적절한 pH는 NR의 경우 6이었고, MB와 MG의 경우 7로 나타났다. 90% 이상의 최대 염료 흡착은 약 60분내에 이루어졌으며, 염료 흡착은 유사 2차반응속도식을 따랐다.

The Dyestuff is fixed to the fiber to color it in a unique way depending on the chemistry between them. Whenever there arose problems in coloring fibers, the chemistry of dyestuff could be adjusted to solve them. That manner new concept dye classes, e.g., reactive dyes, disperse dyes, cationic dyes, have arrived along with the introduction of new fibers. The attempt has made to introduce the new reactive dye to solve this problem.

Polymer cationic agent was prepared by the initial polymerisation of epichlorohydrin followed by amination with diethylamine. Cotton fibre treated with the polymer (6~8% o.w.f.) is highly cationic and exhibit increased substantivity for reactive dyes under neutral to weakly acid conditions. The modified substrate could be dyed with reactive dyes without salt or a little salt from dye bath. The increased concentration of cationic agents resulted in an increase the colour yield. Futhermore, treated cotton has an electropositive surface charge. Adsorption of Reactive dye can be attributed to both van der waals force and electrostatic attraction.

Cationic dyeable polyester(CDP) fabric was annealed at varying temperatures range from $120^{\circ}C$ to $220^{\circ}C$ for 1, 3, and 5 min under tension. Dyeing rates of CDP fabrics were measured with cationic and disperse dyes at $100^{\circ}C$ and $120^{\circ}C$ in water system. Also X-ray diffraction pattern, DSC thermograms and dyeability of fabric with cationic and disperse dyes were investigated. The intensities of X-ray diffraction peaks of annealed fabric were increased with increasing in annealed temperature, and peak became sharp with heat setting temperature. The apparent color depth (K/S) of CDP fabric initially decreased with increase of heat-setting temperature up to $160\~180^{\circ}C$ and then increased at higher temperature. The shearing modulus(G) and surface roughness were increased with annealing temperature.

The ion aggregates formed between cationic triphenylmethane dyes and tetraphenylborate(TPB) or tetrakis(4-fluorophenyl) borate (TFB) anions have been investigated spectroscopically. The photometric sensitivities of the dyes are found to be increasing in the order pararosaniline < malachite green < methyl violet 2B < crystal violet < ethyl violet. Cetyltrimethylammonium bromide(CTAB) and Triton X-100(TX-100) destroy the ion aggregates. By comparing the concentration of surfactant beyond which dye-borate mixed solutions behave identically with the dye blank, the order of hydrophobicity appears to be parallel with that of photometric sensitivity.

Many researches have found that the anionic surfactants are effective when the anionic soil is attached to the cotton fabrics. However, this research investigated the relationship of the super soil removal and surfactants when the anionic and cationic soil was attached to the cationic cotton fabrics. The result is that the cationic surfactants are vary effective for soil removal in the cationic cotton fabrics. The processing and nature of cationic cotton fabrics are treated and investigated as follows: Cotton fabrics are heated in the presence of ethylenimine and acetic acid dissolved in benzene to contain a significant amount of fixed nitrogen. Some polymer was formed but removal by washing with benzene and water. The optinium molor ratio of acid-to-ethylenimine seemed to be in the range 1: 10. The treated cotton fabrics dyed with acid Orange II dyes, and nitrogen content in the treated cotton fabrics were determined by the Kjeldahl method.

Abstract-Many studies have been carried out to improve the dyeability of anionic dyes onto cellulosic fibers. Modification of control using cationic compounds has been most widely used. In this study, an effort was made to cationize cotton fabrics using cellulose-reactive allylamine polymer, namely triazinyl N,N'-dimethyl-N,N'-diallyl ammonium chloride in the previous work. The results showed that the dye-uptake of treated cotton fabrics with acid dyes and reactive dyes markedly increased in the various dyeing conditions. In addition, the dyeing rate of cationized cotton was also faster than that of untreated counterpart. Furthermore, the antimicrobial property was also investigated to determine the effects of cationization.

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.
