    Abstract PDF
    The aim of study was to elucidate dyeability and antimicrobial and antifungal activity of silk fabrics dyed with Sophora Radix extracts according to different mordants.Dyes were extracted from Sophora Radix using ethanol. Then, silk fabrics were dyed with extracts two times by post-mordanting method in which the extract was 60%(owf), the mordant was 3% (owf), L.R was 1:20, the temperature was 60∼70℃, the time of dyeing was 60min., and the time of mordanting was 60min.. The dyeability was evaluated by surface color, K/S values and durability of dye. The skin microorganisms used in this study was S. sureus, B. subtilis, S. epidermidis, P. acnes, P. aeruginosa, E. coli, A. niger, C. albicans and T. mentagrophytes.The results are as follows;1. When mordants were added, K/S value of silk dyed was not improved much and surface color was 2.2Y to 8.8Y in H(hue) value which indicated greenish yellow to reddish yellow 2. The color fastness tests to light, perspiration, dry-cleaning, rubbing, and stain fabric washing show 4∼5th degree which were valuated excellent. The color fastness to fade washing was improved to 3∼4th degree by addition of K2CrO7- mordants. 3. Antibacterial activity of silk dyed using no-mordant as well as mordants was excellent on S. aureus, B. subtilis, S.epidermidis and P.acnes, but showed poor antibacterial activities on P. aeruginosa and E.coli such as gram negative baterials4. Antifungal activity of silk dyed with ethanol extracts was good on A.niger, C.candida and T. mentagrophytes. Especially, on T. mentagrophytes there was no growth of fungus during 72 hours in silk dyed mordanting with SnCl2.2H2O.

    Han Shin Young | 최석철 | 2002, 14(1) | pp.11~17 | number of Cited : 5
    Abstract PDF
    To identify the antimicrobial activity of tumeric and its active compound tumeric was fractionated into four groups dichloromethane extract, hexane fraction, methanol soluble fraction and residue's extract. They were tested for antibacterial activity against E. coli and S. aureus and the methanol soluble fraction was found to be the most active fraction. Compound Ⅰ, Ⅱ and Ⅲ were isolated from TLC and silica gel column chromatography in the methanol soluble fraction. These compounds were analyzed by 1H-NMR and 13C-NMR spectra and identified as curcumin Ⅰ, Ⅱ and Ⅲ. They were also tested for antimicrobial activity against E. coli and S. aureus. Curcumin Ⅰ was the most active curcuminoids due to the phenolic and methoxyl(OCH3) moiety in the same molecular structure.

    육은영 | Hyun Sook Bae | 2002, 14(1) | pp.18~26 | number of Cited : 0
    Abstract PDF
    Chitosan has reactive amino and hydroxyl groups which can be used to chemically alter its properties under the mild reaction conditions. Thus the cationization of Tencel with chitosan is effective to modify the fabric. To investigate the modified properties of Tencel fabric, the tests were performed under the several finishing process with enzyme/glutaraldehyde/softener. The internal structure of Tencel which has the structure of cellulose Ⅱ wasn't changed by enzyme, chitosan and crosslinking agent treatment and the thermal stability was improved by chitosan and crosslinking agent treatment. Wrinkle recovery angle under the dry condition increased highly until 0.1㏖/ℓof glutaraldehyde concentration, and then decreased. Tensile strength of modified Tencel fabric decreased with increasing of weight loss, but it was improved more or less by chitosan, corsslinking agent and softener. Moisture regain was improved by enzyme and chitosan treatment. And antibacterial activity showed nearly 100% on Tencel fabric treated with 0.5% chitosan and adsorption of metal ion increased with increasing of chitosan concentration.

    Study for the Preparation of Deodorizing Fiber (Ⅱ)- Preparations of Deodorizing Fibers using Metal-Phthalocyanines -

    Park,Soo-Min | 오선화 | 2002, 14(1) | pp.27~33 | number of Cited : 0
    Abstract PDF
    The preparations of deodorizing fibers using metal-phthalocyanines have been investigated. The five metal-phthalocyanine derivatives(M-taPc, M=Fe, Co, Ni, Zn, Cu) were prepared in modest to good yields. The metal-phthalocyanine derivative as a deodorant material was introduced to fibers by a dyeing method. The deodorant activity(D.A.) of these deodorizing fibers was measured by chromogenic gas detector tubes. In comparison with untreated fiber, these deodorizing fibers was remarkably effective against NH3 and CH3SH. More than 99% of ammonia can be removed within 20 min. The D.A.(%) of fiber adsorbed M-taPc was more than 80% after 90min.

    The Dyeing Properties of Korean Knotweed Extract(Ⅲ)- Light Fastness-

    Misook Kim | 최석철 | 조경래 | 2002, 14(1) | pp.34~42 | number of Cited : 1
    Abstract PDF
    In order to investigate the light fastness of Korean knotweed extract, the concentrate were prepared and dyed to silk fabric under the various conditions, such as kinds of mordants, methods of mordanting, and the dye concentration. After the dyed fabrics were irradiated for several hours, the color differences and K/S values were measured. Additionally, the light fastness of Korean knotweed extracts and Emodin in liquid solution was compared.The light fastness of silk fabrics dyed with Korean knotweed extract was improved by the introduction of Fe-mordant, but the surface colors on the dyed fabrics shaded into reddish and dark yellow by 80hours irradiation. Color difference of fabrics were increased with concentrations of Korean knotweed extracts. So inconsistent fading behaviour was observed. Color difference of dyed fabrics increased remarkably at the early stage of fading and became slowly down except for Fe-mordanted fabric. Absorbance of Korean knotweed extracts and Emodin in liquid solution were extremely decreased with concentrations of colorants, so inconsistent fading behaviour was observed too.

    Durable Press Finishing of Silk/Cotton Fabrics with BTCA (Ⅰ)- Effect of Treating Conditions on Physical Properties -

    Seokhyun Cho | Muncheul Lee | 2002, 14(1) | pp.43~50 | number of Cited : 2
    Abstract PDF
    Silk/Cotton fabrics were treated with butanetetracarboxylic acid(BTCA) to improve crease recovery and anti-shrinking properties at various curing temperatures and pH values. We investigated the effects of finishing conditions on add-on of BTCA, bending property(B, 2HB), wrinkle recovery angle, shrinkage, and dyeing properties. The Add-on of BTCA increased with increasing curing temperature and concentration. Crease recovery was improved with decreasing shrinkage. Maximum add-on of BTCA was showed at pH 2.5. In case of dyeing and mercerization, silk side treated with BTCA was more flexible than untreated, whereas cotton side was more stiff. In dyeing after mercerization, B and 2HB values were higher and K/S values were doubled nearly. The hand of fabric improved with decreasing B and 2HB by the BTCA treatment. BTCA treatment after reactive dyeing improved crease recovery, and caused no change of color difference. However, BTCA treatment after reactive dyeing didn't improve crease recovery, whereas B and 2HB were decreased considerably by the treatment.

    김태경 | 윤석한 | 신상엽 and 2other persons | 2002, 14(1) | pp.51~57 | number of Cited : 1
    Abstract PDF
    In the prior study, the mechanical properties and the dyeability of the easily dyeable polyester yarn(EDY) were investigated. In this study, to interpret the dyeing behavior of EDY with C. I. Disperse Violet 1, the thermodynamic parameters of dyeing, such as the standard affinity, the heat of dyeing(the enthalpy change), the entropy change, the diffusion coefficient, and the activation energy of diffusion, were obtained from adsorption isotherms and dyeing rate at various temperatures and compared to those of regular polyester (REG-PET).The heat of dyeing(the enthalpy change) and the entropy change for EDY showed smaller negative values than those for REG-PET. This means that the dye molecules in the EDY are combined more loosely than in the REG-PET and that is due to the flexibility of polymer chains of EDY. The diffusion coefficients of C. I. Disperse Violet 1 into the EDY were larger than those for REG-PET, and the activation energy of diffusion on EDY was smaller than that on REG-PET.

    Abstract PDF
    This study surveys the phsical properties of Solo-spun fabrics related to the characteristics of Solo-spun yarns, which were described in previous reports1,2). For this purposes, 6 kinds of fabrics were woven on the pilot loom. 3 kinds of Solo-spun yarns with the 3 level of twist mutiplier of Nm 1/30 and 3 kinds of conventional ring-spun yarns with the same levels of twist multipliers of the same yarn counts. The fabrics were of 2/2 twill and clear-cut finished. The physical properties were surveyed by means of KES-FB system.Solo-spun fabrics seemed to be stiffer than ring spun fabrics as showing the lower extensibility with higher tensile energy, the higher bending rigidity, and the higher shear rigidity. Solo-spun fabrics showed the lower value in surface friction coefficient and surface roughness. For fabric abrasion tests, Solo-spun fabrics showed the higher pill resistance.
