    김미경 | 윤석한 | Taekyeong Kim and 1other persons | 2007, 19(1) | pp.1~11 | number of Cited : 2
    Abstract PDF
    Dyeing of polyester/cotton blends is usually carried out through the two-bath or one-bath two-step dyeing method using proper disperse dyes and reactive dyes for each fiber. However, the dyeing requires relatively long and complicated procedure as well as there are some problems such as lower dyeability. In the present study, new one-bath one-step dyeing process was investigated using disperse dyes having amino groups and hetero-bifunctional bridge compound(DBDCBS) including dichloro-s-triazinyl groups and α,β-dibromopropionylamido groups to improve the dyeability of cotton component in polyester/cotton blends. And the one-bath dyeing properties of polyester/cotton blends was evaluated by various dyeing conditions such as pH, temperature and dye concentration. The optimum dyeing condition was pH 4 and 110-120℃. Color fastness were relatively good because of the colvalent bond formation between DBDCBS-reacted cotton fiber and disperse dye.

    박영민 | KIM BYUNG-SOON | Young-A Son | 2007, 19(1) | pp.12~16 | number of Cited : 0
    Abstract PDF
    Exhaustion increase using cationic dyes on polyamide fibers are not easy work due to the limited amounts of the functional end groups(-COOH) in the substrates. Therefore, to enhance dye exhaustion, polyamide fibers are required to be modified onto desired surface properties of the fibers using anionic bridging agent. In this study, synthetic tanning agent for pre-treatment finishing and cationic dye(berberine chloride) for dyeing of polyamide fibers were used. For surface modification, polyamide fibers were pre-treated with synthetic tanning agent at various concentrations and temperatures. The increased concentration and temperatures of synthetic tanning agents had resulted in exhaustion increase. The modified polyamide substrates showed increased cationic dyeing exhaustions and the corresponding dyeing results from treated samples represented higher exhaustion properties than those of non-treated counterpart. The increased dyeing effects of cationic dye can be attributed to the supplied ionic interaction and electrostatic attraction sites on the surface of polyamide substrates..

    박지헤 | Hyesun Lee | 2007, 19(1) | pp.17~23 | number of Cited : 5
    Abstract PDF
    Dyeing properties using natural material named Sasa quelpaertensis Nakai were investigated under various conditions such as fabric type, pH, concentration, temperature, dyeing time and dipping count. Sasa quelpaertensis Nakai is a unique material in that it is raised only at Halla mountain in Jeju island and is known to have healing effect.Overall, wool fabrics were better than cotton fabrics in all aspects of the dyeing properties showing reddish yellow. For the fastness properties, rubbing, washing and perspiration fastness were excellent but lightfastness was poor as expected.

    Preparation and Physical Characteristics of High-Performance Heat Storage-Release Fabrics with PCMMc

    구 강 | 최종덕 | 최종석 and 2other persons | 2007, 19(1) | pp.24~30 | number of Cited : 2
    Abstract PDF
    Heat storage/release system in textile is a useful tool to increase energy efficiency and enhance comfortable microclimate of clothing. Phase change materials(PCM) are used in regulating storage and release properties of thermal energy. To investigate the temperature regulating ability of fabrics with PCM microcapsule(PCMMc), Nylon fabrics were coated with PCMMc via wet processing and they were characterized by SEM, DSC and infrared thermal analyzer. Also, water moisture transpiration, water penetration resistance, peel strength and washing durability of the fabrics were assessed. The water vapor permeation and water penetration resistance decreased with increasing PCMMc content. In DSC analysis, it can be seen that the microencapsulated fabric showed both exothermic and endothermic phenomena at specific temperature. Peel strength was decreased with increasing PCMMc content.

    Characteristics Changes of the Silk Fibers by Isolated Bacteria from Domestic Museums

    Lee Sang Joon | Sunja Cho | 윤수정 and 3other persons | 2007, 19(1) | pp.31~36 | number of Cited : 1
    Abstract PDF
    There are several factors in the degradation of textiles. The crucial factors in textile weakening are humidity, dust, smoke, sunlight, microorganisms and so on. Especially silk fabrics are more susceptible to microorganisms than other fabrics, because they are mainly consisted of proteins. In this study, we investigated the activities for degrading casein and silk fibers with 2 strains, Bacillus cereus TX1 and Pseudomonas fluorescens TX 2, isolated from domestic museums. They were compared to those of standard control strains, Klebsiella pneumoniae and Staphylococcus aureus, usually used for the antibiotic test of fabrics. The caseinolytic activities of K. pneumoniae and S. aureus were higher than those of isolated strains. But in the cases of silk fiber degrading, B. cereus TX 1 showed the highest activity on both silk 1 and silk 2. Therefore, caseinolytic activities were not coincident with the activity to degrade silk fibers. All strains degraded silk 1(strength retention 100%) better than silk 2(strength retention 50%). It means that bacteria mainly participate in the early stage of degrading silk fabrics, but as time goes by, the importance of bacteria for degrading silk fabrics would decreased. Even though the importance of bacteria may decrease, controlling bacterial activity is necessary to preserve historic silk fabrics.

    Abstract PDF
    In this study, for textile use, the octadecane of phase change materials(PCM) was encapsulated in several micro-diameter shell which prevents leakage of the material during its liquid phase. Microencapsulated PCM(PM) was prepared with the different weight ratio of core material to wall material and by interfacial polymerization methods using polyurea as shell material. Phase stability for O/W emulsion of PCM and PVA aq. (PE) was evaluated by Turbiscan Lab. The capsule formation was identified using FT-IR. Physical properties of microcapsules including diameter, particle distribution, morphology were investigated. Thermal transport properties of suede treated with PM(SPM) were determined by KES-F7 system.

    Surface Modification of Polyacrylonitrile by Low- temperature Plasma

    Eun-Deock Seo | 2007, 19(1) | pp.45~52 | number of Cited : 1
    Abstract PDF
    Polyacrylonitrile(PAN) fiber was treated with low-temperature plasmas of argon and oxygen for surface modification, and its surface chemical structure and morphology were examined by a field emission scanning electron microscope(FESEM) and a Fourier-transform infrared microspectroscopy(IMS). The argon-plasma treatment caused the only mechanical effect by sputtering of ion bombardment, whereas the oxygen plasma brought about a chemical effect on the PAN fiber surface. The experimental evidences strongly suggested that cyclization of nitrile group and crosslinking were likely to occur in the oxygen-plasma treatment. On the other hand, with the argon-plasma treatment, numerous tiny pits resulted in ranging from several tens to hundreds nanometers in radius. The plasma sensitivity of functional groups such as C-H, C≡N, and O-C=O groups in the PAN fiber was dependent on their chemical nature of bonding in the oxygen-plasma, in which the ester group was the most sensitive to the plasma. Vacuum-ultraviolet(VUV) radiation emitted during plasma treatment played no substantial role to alter the surface morphology.

    The Process Optimization for Development of Super Deep Black Fiber

    Taekyeong Kim | 전준형 | 김은철 | 2007, 19(1) | pp.53~60 | number of Cited : 5
    Abstract PDF
    In order to optimize the process for development of super deep black fiber, the silica-containing polyester fabric, SN2000, was investigated in terms of mass reduction process by sodium hydroxide, selection of high color strength dyes, and resin treatment. As the results, the mass reduction condition which used 15g/L of sodium hydroxide at 120℃ was determined and Dianix Deep Black Plus was selected for the best deep coloration at around 5% owf. Contrary to the prevailed understanding that the additional use of chromatic dyes would enhance the deep coloration, four kinds of chromatic dyes such as yellow, red, blue, and green dyes did not make great effect on the deep coloration. To increase the effect, the commercial resin that has low refractive index was used additionally and the resin made it possible to lower the lightness of the fabrics down to 8.7 which was generally accepted for super highly deep black fabric.
