  • Diisodecyl phthalate (DIDP) which has high physical flexibility, various colors, low viscosity, high stability is used as coating material in ballon, vinyl ink, tent, textile, home and cars interior design and electric cable. In rodents, DIDP is suspected to be a peroxisome proliferator, a nongenotoxic carcinogen. In this study, we performed the carcinogenicity test of DIDP. (omitted)

  • In this study, the polyurethane microcapsules for non-aqueous dyeing containing iron oxide and disperse dyes were prepared by in-situ polymerization method using hexamethylene diisocyanate(HDI) with ethylene glycol(EG). And the size, shape, and particle size distribution of microcapsules prepared were investigated. The size and shape of microcapsule were observed by optical microscope and scanning elecron microscope. The particle size distribution was analyzed by particle size analyzer. The microcapsule size and its distribution were largely effected by the existance of surface active agent in the system. When a surfactant did not exist in the system, the size distribution of microcapsules prepared was much uneven. By adding a surfactant, this phenomenon was disappeared. And the size of microcapsule was also effeced by the hydrophobicity of core material(disperse dye). It was considered due to the difference of dispersity of core materials. And the size of microcapsule prepared was inversely proportional to the stirring speed.

  • "Saikdong" is a material that represents the Korean aesthetic behavioral pattern of colors. It shows the unique harmony of the color combination with the use of simple combined colors. The objective of this paper is two-folded. First, it is to explore the direction of Korean Design. Secondly, it is to find out aesthetic charateristics and consciousness in Saikdong. 17 traditional costumes made with the designs of Saikdong were selected from three museums in Seoul. The most properly matched color hues selected after comparing each color with the Pantone Textile Color Specifier. The results were shown as follows. 1. Korean design is to recreate the traditional objects considering the contemporary circumstances. 2. Contrast effects in lightness and saturation are very noticeable in Saikdong. Saikdong maintains the same widths of color stripes with the asymmetric balance of hues which give the rhythmical arrangement of colors. 3. Sikdong contains the shamanic wishes that everything is going well and the desire for the beauty. 4. The aesthetic consciousness of Saikdong has turned out to be happiness and harmonizing.rmonizing.

  • The preparation of responsive fibers from acrylic fibers is studied. Various responsive fibers, such as fibers which change their color on exposure to light or with change in temperature, have been developed and are used commercially However, the responsive material in these fibers are not the fiber itself but chemicals in microcapsules attached to the fibers by finishing, and few fibers exhibit responsive properties by itself. The partial hydrolysis of polyacrylonitrile fibers to obtain pH responsive fibers is presented in this paper. Partial hydrolysis was effected by control of the concentration of the sodium hydroxide used in the hydrolysis, hydrolysis temperature and time. The degree of hydrolysis was evaluated by nitrogen content of the hydrolyzed fibers and their response, change in length, to aqueous solutions of varying pH was studied by continually changing the pH. Significant changes in lengths with pH were observed and the gel transition behavior varied with the conditions of hydrolysis. The hysteresis of the length change was also studied to evaluate the possibilities of using hydrolyzed acrylic fibers as pH sensors.

  • In order to make a supermicrofiber fabric with PET/co-PET sea-island type filament fiber, the optimum conditions of dissolution of co-PET composite filament fiber was examined. The data set was made at various organic acid concentration and steam temperature with treated time as a main variable. At the same time, the microstructure changes by organic acid treatment of sea-island type PET supermicrofibers were monitored by thermal analysis morphology, DSC thermgrams and SEM images. Weight reduction behavior of supermicrofibers by caustic treatment was investigated in a comparative method. The termination of dissolution was also confirmed using DSC thermgrams and SEM images.

  • We have designed and synthesized the colorimetric chemosensor through the reactions of 1,2-anthraquinone and indol-3-carboxaldehyde. Due to its well conjugated D-π-A system and the existence of NH-fragment in indole moiety, we expected that the chemosensor can detect target anions with NH-fragment in indole part of the structure. In this regard, UV-Vis absorption spectra were measured to investigate sensing properties of the probe toward different anions in DMSO. This chemosensor shows to detect fluoride anions with absorption change in intensity. These properties are mainly related to the deprotonation effect. ICT system in this molecule was also observed by the computational approach using Material Studio 4.3 package.

  • The designed dye material, namely 2-(4-(9H-carbazol-9-yl)benzylidene) compound, was synthesized. After the reaction, the solid was filtered and purified by recrystalization with acetone/water. To confirm and analyze its synthesis and structural formation, the single crystal was prepared and its measurement was carried out. A yellow needle crystal of C22H13N3 were made on a Rigaku R-AXIS RAPID diffractometer using graphite monochromated CuKα radiation. All details were suggested and introduced to support and communicate this study.

  • We have studied on the experimental variables such as optimum adsorption condition, color changes, light fastness, antimicrobial properties, and wash durability of the cotton fabrics treated with gallnut extracts. Treatment of gallnut extracts on the cotton fabrics was optimally achieved at 60C for 60min. Gallnut extracts did not cause unintended color change after treatment on the cotton fabrics dyed with reactive dyes. The cotton fabrics treated with gallnut extracts showed good light fastness, though we took into the account the extract is a natural material. The cotton fabrics treated with 10.0% o.w.f. of gallnut extracts had strong antimicrobial activity and good wash durability.

  • This study explores the solution of a variety of conditions of the natural dyeing with the Mulberry. To obtain this, the Cu complex compound was added into the extracts. The Mulberry extract was added the Copper acetate to obtain the Black sediment the metal complex compound of anthocyanidin. According to the result of using the complex compound of the solid material, the dyeing properties were excellent. The metal complex compound acted as a mordant, thus it reduced the process of mordanting in the natural dying.
