The effects of synthesis conditions on characteristics of the calcium-azo complex pigment, C.I. Pigment Red 57:1, were studied. It was mainly considered that the industrially required synthesis conditions for lowering electrical conductivity of the pigment solution keeping pigment quality such as particle size and color characteristics. Three parameters were chosen as control factors during the synthesis. The first was the amount of hydrochloric acid added to transform sodium nitrite into nitrous acid. The second was the amount of calcium chloride added to insolubilize the synthesized azo dye. The final factor was pH control during the coupling reaction. The electrical conductivity and pigment aggregate particle size were dependent on the amount of hydrochloric acid and calcium chloride. Higher HCl concentration gave brighter yellowish-red color because of smaller particle aggregate size and narrower size distribution. Amount of charged ions in the synthesis process might affect the "lake" formation resulting different particle aggregate size and color shade.

The effect of salt milling process on the crystal size, morphology, and color characteristics of C.I. Pigment Red 57:1 was studied. The primitive morphology and color properties of the pigment after synthesis were studied in the former series work. The size and morphology of primary particles and the second aggregation features should be considered because they are very important to determine pigment quality. We compared the primary morphology of pigment particles before drying with the secondary aggregated morphology of pigment particles after drying and salt milling process. Morphological properties were investigated by particle size analysis, X-ray diffraction, and scanning electron microscopy and color measurement was carried out. Significant reduction in particle size as well as enhanced crystallite size after salt milling process was observed. This result might give a difference in color of the pigment, turning into brighter and more blue-toned red color. It was revealed that synthesis condition affect the morphology and color of the pigment even after milling. Increase in HCl concentration in the synthesis process enhanced crystal size and quality forming bluer-red pigments but an increase in
concentration resulted in more amorphous crystals forming darker-red pigments after salt milling.

Two new D-
-A dyes were synthesized by the condensation reaction between active methyl and aromatic aldehyde and its biothiol sensing properties in DMSO/water were investigated by UV-vis spectroscopy. Upon addition of
, the solution of D-
-A dyes showed color change and the absorption band shows a formation of a dye-
coordination complex. These dyes exhibited high selectivity for
as compared with other cations. The dye-
could be recovered by adding glutathion(GSH). The absorption intensity of dye-
increased only by the addition of glutathione(GSH). The competition experiments revealed that no obvious interference was observed by performing the titration with the mixture of glutathione(GSH) and other amino acids. The results indicated that these D-
-A dyes were highly selective for glutathione(GSH) detection.

Molecules always show broad absorption band envelopes, and this results from the vibrational properties of bonds. The width of an absorption band can have an important influence on the color of a dye. A narrow band imparts a bright, spectrally pure color to the dye, whereas a broad band can give the same hue, but with a much duller appearance. Typically, half-band widths of cyanine dyes are about 25nm compared to value of over 50nm for typical merocyanine dyes. Thus, cyanine dyes are exceptionally bright. The factors influencing the width of an absorption band can be understood with reference to the Morse curves. The width of the absorption band depends on how closely the bond order of the molecules in the first excited state resembles that in the ground state. We have quantitatively evaluated the "molecular structure-absorption band shape" relationship of dye molecules by means of Pariser-Parr-Pople Molecular Orbital Method(PPP-MO).

New series of phthaloperinone dyes were synthesized by the condensation reaction between tetrachloro-phthalic anhydride, 2,3-naphthalene dicarboxylic anhydride and o-phenylenediamine, 1,8-diaminonaphthalene, 1,2-diaminoanthraquinone. These dyes absorb at around 370-490nm. It was found that introduction of naphthalene and anthraquinone moiety on the perinone system produces a large bathochromic shift of 100nm. The synthesized dye 7 containing anthraquinone moiety in perinone chromophoric system exhibited superior heat stability and bright color as yellow chromophore. New dye 7 have been investigated in terms of interacting with volatile organic compound(VOC)
. The sensing behaviour of the dye 7 toward
was studied by UV-vis absorption spectroscopy. Sensing mechanism of dye 7 to
was supported by theoretical calculations based on DFT method.

DOI : 10.5764/TCF.2015.27.4.281
The aim of this study was to investigate the possibility utilizing Metasequoia(Metasequoia glyptostroboides) cone as a new natural dye resource. In previous study, dyeing onto cotton fiber was carried out and Metasequoia cone colorant showed low affinity to cotton fiber and maximum dye uptake was obtained at pH 3.5 showing YR Munsell color. For further evaluation of its efficacy as a new natural dye resource, effects of dyeing conditions and mordanting on dye uptake, color change, and colorfastness were investigated for silk fiber. Metasequoia cone colorant showed good affinity toward silk fiber showing YR Munsell color and maximum dye uptake was shown at pH 3.5. Post-mordanting with Cu and Fe improved dye uptake, especially Fe(
) mordant was effective as much as 2 times higher dye uptake comparing with un-mordanted sample. The color of dyed fabrics with mordanting showed YR Munsell color. Fe mordanted fabrics appeared dark gray~black color. Colorfastness to washing was relatively good, whereas lightfastness of the dyed fabrics showed grade 2. It was confirmed that Metasequoia cone colorant can be used as a new dye resource for silk fiber getting brownish yellow to dark gray/black color depending on mordant type. In addition, it showed antimicrobial functionality.

This study was executed to substitute Carbon-arc method, which is a method currently used for testing light-fastness of military textile products, with Xenon arc method. Specimens used in the study were classified according to the fabric material and color of military textile products and were composed of 11 items of 42 kinds with different colors. Light-fatness test was done by comparing the result of Carbon-arc(KS K 0700) and Xenon arc(KS K ISO 105-B02) method. In Xenon arc method, blue wool reference materials of 1~8 was used, and exposure condition preferred in American continent and light exposure method 3 were applied. After testing with both methods, grade of light-fastness, color difference, reflectance and color were examined. Even though there was a slight difference among 42 specimens used in the test, results exceeded the quality standard both in Carbon-arc-lamp and Xenon arc-lamp. Therefore, it was confirmed that applying KS K ISO 105-B02 together in the KS K 0700-regulated Ministry of National Defense standard and purchase order would also fit.

DOI : 10.5764/TCF.2015.27.4.301
This study optimizes dyeing conditions for polyamide-imide fabric using cationic dyes. Dyeing and fastness characteristics of polyamide-imide fabric were investigated with three cationic dyes and 2-hydroxyacetophenone as a swelling agent under various dyeing conditions such as dye and swelling agent concentrations, dyeing temperature and time, pH of dye bath. The dyeing properties were evaluated in terms of dye exhaustion, K/S value and color fastness. The optimized dyeing temperature and time were
for 90 min for the dyes. Under weak acidic conditions in the range pH 5 to 7, the exhaustion of cationic dyes could be enhanced leading to higher adsorption. Wash and rubbing fastness properties were generally good, while light fastness was slightly low, which can be attributed to the poor photo-stability of the cationic dyes.

This study is the high contraction processing conditions set by the method of the CPB process. And the ultimate goal of this study is the high contraction of the CPB processing test method that can solve the problems of the high-contraction fabric processing method of the current jet dyeing machine. Non-coating process(CPB process) developed by the expression of a soft touch, light weight, functional and to develop excellent breathable nylon fabric. The nylon fabrics established the optimum processing conditions through the high contraction of the various test conditions, the CPB system.(The benzyl alcohol was used as the main constrictor.) At this time, the warp and weft contraction of nylon fabric was about 20%. And it established the constrictor concentration, the treatment temperature, time of a variety of tests. Also non-coating process(CPB process) can develop soft touch, lightweight, excellent air permeability. As a result, we developed a high contraction nylon fabric having a uniform surface. Manufactured fabric is used for Wind-proof and Down-proof.

A pre-treatment process is essential for getting high quality of digital textile printing(DTP). In this study, we have studied three kinds of carrageenan polymer(k-,
-, i-Carrageenan) as a pre-treatment thickening agent for the first time. Alginate polymer was also examined and its results were compared with that of the three kinds of carrageenan polymer. To confirm the performance of each thickening agent, we examined for a sharpness, color strength and fastness(washing, rub, light). The result showed that
-Carrageenan has superior property in sharpness with low viscosity and i-Carrageenan was excellent in the color strength among the pre-treatment agents. Washing fastness to color change and staining for the all samples were 4 or 4-5 grade. Both dry and wet rubbing fastness of the samples were 4-5 grade. However,
-Carrageenan coated sample has the lowest grade in light fastness. As a result, we found the possibility of carrageenan polymer as pre-treatment agent.

This paper aims to manufacture nonwoven fabrics by wet-laid technology using Vectran
one of the highly favoured high-performace fiber. In previous study, a novel evaluation on fiber dispersion was studied to select optimum surfactant by the need for the control of fiber dispersion in water with reference to wet-laid nonwoven technology. 3 Types of sulfonate anionic surfactants were chosen and added in a stage of agitation to improve dispersion behavior of fibers in water. It was observed that the state of fiber dispersion in water affected various properties of nonwovens, including appearance, physical properties, and mechanical properties. Nonwoven added SDBS was uniform in web structure, thickness and weight. Its average pore was small in size and consisted of fine pores and the value of porosity was high. Further, the difference of tensile value between 2 directions was the least. Consequentially, as the dispersion behavior of fiber increases, nonwoven shows more balanced and uniform physical properties in all directions.

Polyketone fiber, a newly developed high strength fiber, has a tenacity and modulus similar to the paramid fiber, and can be used for reinforcing mechanical rubber goods(MRG), such as tires, hoses, and technical textiles. In addition, aliphatic polyketone, which has excellent strength, modulus, chemical stability and reasonable price, is being developed only in South Korea. It will be expected for replacement of super fiber such as aramids and increasing the technical textile market share. This paper surveys the mechanical properties of polyketone fiber yarn for technical textiles. For this purpose, two kinds of yarns are prepared, mechanical properties of coated and uncoated polyketone yarns such as tensile strength, elongation and modulus were examined before and after weather resistance test(temperature
, humidity 60%, amount of power
). The differences of mechanical properties between uncoated and coated yarns for high functional technical textiles and composite materials are estimated through this study.

The interaction between curcumin(1,7-bis[4-hydroxy-3-methoxyphenyl]-1,6-heptadiene-3,5-dione) and ethylamines was studied in DMSO:
(5:1, v/v) using absorption and fluorescence measurements. The association constant,
, and the Stern-Volmer constants were calculated by the Benesi-Hildebrand and Stern-Volmer equation, respectively. Curcumin displayed marked UV-Vis absorption changes and highly responsive fluorescence quenching in the presence of ethylamine and the quenching ability was enhanced almost linearly with the concentration of ethylamines. The apparent Stern-Volmer constant measured for the ethylamine-curcumin system was about 1000-fold greater than that of the triethylamine-curcumin system, indicating considerably greater quenching efficiency of ethylamines.
