A Study on the Surface Properties of Wool Fabric Treated with Enzyme
Textile Coloration and Finishing, volume 13, issue 4, 2001, Pages 227~233
Wool fabrics were pre-treated with corona prior to treating with enzyme for shrinkage resistance. Commercial protease and cellulase were used for degradation of wool and the treatment conditions such as enzyme amount, treating time, and assistant chemicals. Friction coefficient and zeta-potential were measured to certificate an effect of treatment condition on the handle of wool fabric. Corona pretreatment make the wool fabric soft, which result in the decrease of friction coefficient and zeta-potential. Scale removal of wool surface was observed by scanning electron microscope. Amino acid analysis shows the effectiveness of enzyme, and corona pretreatment does not cause severe internal damage.
Washing Fastness of Polyester Artificial Suede Fabric According to Reduction Clearing Method
Textile Coloration and Finishing, volume 13, issue 4, 2001, Pages 234~240
In order to improve the washing fastness of dyed polyester artificial suede fabric, it was dyed by using auto and anthraguinone type disperse dyes and treated with 3 different reduction clearing methods. The reduction clearing methods used in this study were normal alkaline reduction clearing,
gas replacement method, and ultrasonic treatment during normal reduction clearing. The results were as followings ; The washing fastness property of dyed polyester artificial suede fabric was slightly improved by reduction clearing with
gas replacement or with ultrasonic treatment comparing with normal alkaline reduction clearing. It was found that the use of
gas replacement or ultrasonic treatment during reduction clearing eave effective removal of unfixed dyes on the fiber surface. We also obtained that the azo type disperse dye on polyester artificial fabric suede fabric showed higher wash fastness than anthraquinone type disperse dye.
Natural Indigo Dyeing on Wool Fibers (I)
Textile Coloration and Finishing, volume 13, issue 4, 2001, Pages 241~248
Natural indigo dyeing has been used mainly on cellulosic fibers and silk during the course of history in Korea. In order to extend the usage of this one of the most important natural dyes, its dyeability on wool fabrics has been studied to find out the optimum dyeing condition for wool fiber which is susceptible to alkaline medium. The dyeing method used was hydrosulphite vat of extracted dye. K/S values of dyed fabrics were investigated to analyze the dyeability of natural indigo on wool fibers and colors were measured through
and Munsell Values. Highest K/S values were obtained at the temperature of 60(C and pH 7 to 8. The Munsell Values for hue of wool fabrics dyed with extracted indigo powder using hydrosulphite vat fell mostly in PB range. As the dyebath pH increased, blueness increased. Different dyeing conditions resulted in change of colors of dyed fabrics due to the difference in amounts of indigotin and indirubin contents within the dyed fiber as shown by HPLC.
The Interpretation of Dyeing Behavior of Poly(trimethylene terephthalate) Fiber with a Disperse Dye
Textile Coloration and Finishing, volume 13, issue 4, 2001, Pages 249~255
To interpret the dyeing behavior of PTT fiber with C. I. Disperse Violet 1, the thermodynamic Parameters of dyeing, such as standard affinity, heat of dyeing(enthalpy change), entropy change, diffusion coefficient, and activation energy of diffusion, were obtained from isotherms and dyeing rates at various temperatures and compared with those of PET fiber. The heat of dyeing(enthalpy change) and the entropy change of PTT fiber showed smaller negative values than those of PET fiber. This means that the dye molecules in the PTT fiber are combined more loosely than in the PET fiber and that is due to the flexibility of polymer chains of PTT fiber. The diffusion coefficients of C. I. Disperse Violet 1 into the PTT fiber were larger than those for PET fiber, and the activation energy of diffusion on PTT fiber was smaller than that on PET fiber.
Modification of Dyeing Property of Polyester Fabrics by UV Irradiation
Textile Coloration and Finishing, volume 13, issue 4, 2001, Pages 256~263
Polyester fabrics were irradiated by UV produced by the low pressure mercury lamp. UV irradiation broke a C-H bond of PET fiber and caused the carbonyl groups on the fiber surfaces. Surface modification of PET fibers were accelerated by pretreatment with methanol, ethanol and acetone. The irradiated PET was dyed with basic dyes having cationic groups. The dye uptakes were proportional to irradiation times, and in inversely proportional to irradiation distances. The tensile strengths of PET fabrics decreased by UV irradiation. Washing fastness of PET dyeings were good, about 4-5 grade,andlightfastnesswerepoor, about l grade. ,
Decomposition of Ethylene Glycol by Catalytic Wet Air Oxidation
Textile Coloration and Finishing, volume 13, issue 4, 2001, Pages 264~271
Catalytic wet oxidation of ethylene glycol as refractory compound was studied in a batch slurry reactor using lwt%
(1:1) and 5wt%
. Experiments were conducted to investigate theeffects of temperature, initial ethylene glycol concentration, catalyst dosage and PH on the ethylene glycol decomposition. When compared with the uncatalyzed reaction, the use of catalysts could increase the rate of ethylene glycol decomposition. The lwt%
catalyst was preferable to the other catalysts for the destructive oxidation of ethylene glycol. The reaction rate was first order with respect to initial concentration of ethylene glycol. In acidic condition the removal efficiency of ethylene glycol was good, but there was a significant leaching of platinum. Small amount of acetic acid, oxalic acid, masonic acid and formic acid as intermediates were detected during catalytic wet air oxidation of ethylene glycol.
A Study on the Shrink Resist Finish of Wool Fabric(I) - Effect of Treating Condition on Mechanical Properties of Wool Fabric with Chlorination and MONAMIN BTN Resin -
Textile Coloration and Finishing, volume 13, issue 4, 2001, Pages 272~281
Shrink resist finishing of wool fabric was carried out with MONAMIN BTN shrink resist agent after chlorination with D.C.C.A.(dichloro isocyanuric acid). The purpose of this study is to investigate the effect of treating conditions, such as concentrations of D.C.C.A and MONAMIN BTN, pH of treating bath, dying times, curing times and temperatures, on shrink resist finishing. Mechanical properties of the treated fabric were measured by KES-FB system. The optimum chlorination of wool corresponds to 2∼3%(o.w.f.) of D.C.C.A. without rendering the damage on surface of wool fiber. Also it seems likely that the shirink resist finishing carried out at 2 ∼3%(o.w.f.) of MONAMIN BTN and pH 7∼8 of treating bath is effective in increasing a softness of hand.
