Relationship between Substituents of Aminoazobenzene Disperse Dyes and Dyeing Properties
Kim, Sung Dong ; Kwak, Tae Soo ; Lee, In Yeol ;
Textile Coloration and Finishing, volume 9, issue 6, 1997, Pages 1~9
Four aminoazobenzene disperse dyes derived from different N-ethyl-N-substitutedalkylanilines and 2-chloro-4-nitroaniline, were synthesized and their chemical structure were analyzed by 500 MHz NMR spectroscopy. The wavelength of maximum absorption of the synthesized dyes, which was dependent on the electron withdrawing ability of the substituent, was in the range of 499.5~526.0nm. As terminal substituent became polar, the dyeing rate of disperse dye increased, and the exhaustion rate of dyes having cyano or hydroxy group became lower, that of the dye having acetoxy group higher. The wash fastness of polyester fabric dyed with disperse dyes possessing the polar group improved probably due to the increased dye-fiber interaction.

In order to improve the anti-static property of several hydrophobic fibers by sputter etching, polyester, polypropylene and poly(p-phenylene sulfide) have been etched by sputtering in the presence of argon gas and the resulting anti-static property investigated by half time decay, the time of water permeation, weight loss rate and scanning electron microscope(SEM). The temporary change and durability of anti-static property of samples treated with sputter etching were evaluated. The results were as follows; 1) Half time decay of samples treated with sputter etching were decreased about 18~38%. According to increasing sputter etching time, half time decay is decreased. 2) The wettability and weight loss rate of treated samples were increased remarkably. According to the SEM photographs, many microcraters on the substrate surface by the sputter etching were observed. 3) Although the washing treatment and the time elapsed after treatment are allowed longer, the variation of half time decay hardly can find.

Textile Coloration and Finishing, volume 9, issue 6, 1997, Pages 18~25
The change of crystalline structure and mechanical properties of i-PP films which had before isothermally annealed at various temperature and times have been studied. The following results were abtain The crystallinity and crystallite size of the samples showed increasing above the annealing temperature of 13
and these are equilibrated after an annealing time of 30min. When the crystalline form was at annealling condition were below 13
, 2min, subsequently achieving an
mixing form and at 13
, 10min, the crystalline form entered an
form transition. It is achieved a typical
form at 15
. The value of T'm was increasing until 13
but it was not founded at 15
. The slopes which represented crystalline form in an Avrami plot differed from each other within the range of this experiment.

In order to remove the pollutants effectively in the dye-processing wastewater by chemical precipitation, coagulation and flocculation test was carried out using several coagulants on various reaction conditions. It was found that the Ferric sulfate was best coagulant for the treatment of mixed dye-processing wastewater. When the Ferric sulfate dosage was 1,100mg/
, the COD removal rate was very high(50%), and the color was removed very effectively. The COD was decreased relatively well up to 40%, when Alum was dosed as coagulant. But it was difficult to remove the color effectively. Test results about COD removal for the Ferrous sulfate and the Ferric chloride used were mostly same as those of the Alum used. However, the color removal by the Ferrous sulfate was much better than the case of the Alum or the Ferric chloride. It was found that the COD removal was increased and the sludge yield was decreased by pH control before polymer flocculant addition, during the jar test for the Ferrous sulfate and the Ferric sulfate as a coagulant.
천연염색에 사용되는 천연매염제에 관한 연구(I) - 볏짚재 -
Textile Coloration and Finishing, volume 9, issue 6, 1997, Pages 33~41
This paper surveys the extraction condition of polygenetic natural dye, Sappan Wood and the effect of ash to the dyeability and fastness. The appropriate time for extracting Sappon Wood was 1hour. The pH was increased as the amount of ash increase. The pH was nearly invariable according to the time of ash solution, the extracting times and temperature. Absorbance of dyeing fabrics was about 480nm. From the result of K/S value determination of fabrics, 10g/
quantity of ash was surfficient for treatment and the amount of Sappon Wood was in 100% o.w.f.. K/S value of fabrics pre-mordanted or post-mordanted were higher than that of fabrics simultaneous mordanted.K/S value was increased as pH of mordanting bath decrease and pre-mordanting and post-mordanting fabrics increased the amount of absorption (K/S value) compared with non-mordanted fabrics. It was found that pH of mordanting bath affected the amount of absorption and color change of dyed fabrics. Light fastness of fabric dyed was very poor and the fastness of fabric dyed was not influenced by the mordanting conditions and methods.
The Effect of Bola-form Electrolytes on Dyeing Behaviors of Protein Fibers
Textile Coloration and Finishing, volume 9, issue 6, 1997, Pages 42~50
Bola-form electrolytes were synthesized by the reaction of pyridine with 1, 4-dibromobutane or 1, 10-dibromodecane, respectively. The effects of these electrolytes were studied in the dyeing of wool fabric with Orange II. The depth of shade of wool fabric with pretreated electrolyte were independent to the dyeing temperature and higher than those of one untreated. In the case of pretreating the electrolytes, there are no differences in the effects in dyeing behaviors between the 1, 4-dipyridiniumbutane and 1, 10-dipyridiniumdecane. But when the wool fabrics were dyed in water containing these electrolytes, dyeing behaviors were different to the numbers of carbon atom in electrolytes. 1, 4-dipyridiniumbutane has positive effects on the dyeing.
New Weighting Functions for the Modified CIELAB Colour-Difference Formulae
Kim, Dong-Ho ;
Textile Coloration and Finishing, volume 9, issue 6, 1997, Pages 51~57
The lightness, chroma and hue tolerances with respect to the standard colour position in the CIELAB space have been studied in detail using the various existing data sets and the set form this study. The lightness tolerance showed a clear dependency upon the metric lightness for medium to light colour, but in the case of dark colours there was a discrepancy between the data sets. Both the chroma and hue tolerances showed dependency upon both the chroma and hue-angle and not the single dependency upon the metric chroma, as assumed in the CIE94 formula. New weighting functions were derived from the above experimental evidence, and finally a new formula, LCD(Leeds Colour Difference) was proposed. The LCD formula is nearly as simple and flexible as CIE94 but smoothes the individual weighting functions, especially for lightness tolerances for light colours and chromaticity discrimination near the blue region.
A Study on the Durable Press Finishing of Cotton Fiber Treated with Polycarboxylic Acid
Textile Coloration and Finishing, volume 9, issue 6, 1997, Pages 58~67
PTCA(1,2,3-propanetricarboxylic acid) and BTCA(1,2,3-butanetetracarboxylic acid) are selected as new nonformaldehyde agents for ester crosslinking of cotton cellulose to replace the traditional DMDHEU reagent. A goal of this research is to propose unknown ester mechanism of cotton cellulose by PTCA or BTCA using crystal structure model suggested by Meyer and Takahashi. In pursuit of these goals, we have treated 100% cotton broad cloth with PTCA or BTCA and different catalysts. They were used with
catalysts to produce nonformaldehyde fabric finishes. Treatments were applied to all cotton fabrics using a pad-dry -cure process. The esterfication of cotton treated with BTCA or PTCA was investigated using Fourier transform infrared(FT-IR) spectra and the breaking strength, abrasion retention and discoloration properties were determined to prove the durable finished fabrics. Patterns with respect to abrasion resistance were more complex. Because PTCA and BTCA add-ons were comparable, the data suggest that the more effective catalysts,
and mixed phosphate
) are effecting either a great number of crosslinks in the cotton or producing crosslinks that differ in actual structure.
A Study on Microencapsulation of Perfume and Antibiotics by In-situ Polymerzation(I)
Textile Coloration and Finishing, volume 9, issue 6, 1997, Pages 68~73
Urea/formaldehyde(UF) and melamine/formaldehyde(MF) microcapsules containing perfume and 2,4,4'-trichlroro-2-hydroxydiphenyl ether(DP) were prepared by the in-situ polymerization using urea and formaldehyde. Effects of dispersing agent, accelerating agent, formaldehyde, agitation speed on the mean diameter of microcapsules were investigated. The diameter of microcapsule was decreased with increasing dispersing agent concentration. A slight increase in the diameter was observed when the concentration of film forming material was increased. The diameter of microcapsule was decreased with increasing agitation speed up to 8,000rpm. The mean diameters of UF microcapsule prepared at 8,000rpm are about 3
m. A slight decrease in the diameter was observed when the concentration of resorcinol was increased.
The Effect of Finishing Condition on the Antimicrobial Properties of Chrome-Tanned Leather for Apparel.
Textile Coloration and Finishing, volume 9, issue 6, 1997, Pages 74~78
This study was performed to obtain the basic data of the effect of antimicrobic finishing on chrome-tanned leather for apparel. This study was to examine the effect of conditions of antimicrobic finishing on content of antimicrobic agents in the specimen by analysis and on the antimicrobic activity of specimens by means of shake flask test. The optimum conditions of antimicrobic finishing were found to be ; the concentration of Si-QAC-0.5%(o.w.f.), treating time-30minute, and drying method-air drying.
감성물질의 마이크로캡슐화에 의한 감성기능 섬유의 개발(IV) -감온변색 기능섬유-
Textile Coloration and Finishing, volume 9, issue 6, 1997, Pages 79~86
The microcapsule for thermochromism is based on the polymerization reaction between epoxy resin and amine curing agent. The preparation process of microcapsule is based on dissolving or dispersing a hydrophobic core materials[one-dye-black(OBD), bis-phenol A(BPA), cetyl alcohol] in an aqueous solution of gelatin, epoxy resin and isophorondiamine(IPDA) ; the gelatin and IPDA used as a dispersion stabilizer and an hardening agent, respectively. The structures of epoxy resin and microcapsule materials have been analyzed by FT-IR and UV/Vis spectra. The mean diameter and size distribution of microcapsule are 1.46~1.75
and 1.42, respectively. The DSC thermograms of microcapsules indicated 2 kinds of endothermic peaks at 47 and 322
. This is possibly corresponding to the melting peak of core material and wall meterial. These microcapsules are applied to the fabric by printing. Complex finished fabric showed a good wear resistance on rubbing test and the print pattern to the cotton fabric showed a reversible thermochromism ;
are 580 nm below 4
and 276.5nm above 4
in ethanol/water(2/8), respectively.
Dyeability and Enzymetic Treatment of Wool Pretreated with tert-Butoxide
Textile Coloration and Finishing, volume 9, issue 6, 1997, Pages 87~95
Wool samples were treated by potassium tert-Butoxide(t-BuOK) in anhydrous tert-butanol to remove the bound surface lipid-layer, and the weight loss behaviors in protease solution and dyeabilities of the samples were studies. The C/N ratio of the surface of the t-BuOK-treated wool was shown to be 4.3 from XPS analysis. From SEM pictures any remarkable change in the shape of surface curticle during the proteasw treatment was not observed regardless of prior t-BuOK treatment. Dyeing rate and equilibrium adsorption of Orange II, a typical levelling type acid dye, on wool were not changed by protease or t-BuOK treatment, but those of Milling Cyanine 5R, a typical milling type acid dye, on wool were greatly enhanced by t-BuOK treatment in spite that, from alkali and urea-bisulfite solubilities, no damage on the inner part of wool fiber was expected by t-BuOK treatment.
