A Study on the Mechanical Properties to the Weaving Design & Finishing Condition of Wool Fabric
Textile Coloration and Finishing, volume 12, issue 3, 2000, Pages 159~165
This study surveys the fabric mechanical properties according to the weaving design & finishing conditions of wool fabrics for quality control in the process. For this purpose, 8 kinds of Twill groups and 3 kinds of Plain groups weave fabrics, totally 428 woven fabrics are prepared with change of the yarn count, density and finishing method. Fabric thickness, bending rigidity, extensibility, shear rigidity, formability of the fabrics were measured and discussed with weaving design & finishing conditions.
Antimicrobial Activity and Application of N,N,N-Trimethylchitosan Ammonium Chloride (I) - Antimicrobial Activity against MRSA -
Textile Coloration and Finishing, volume 12, issue 3, 2000, Pages 166~173
Various kinds of water soluble N,N,N-trimethylchitosan ammonium chloride(TMC) with different molecular weights were synthesized to examine the antimicrobial activity against Methicillin Sensitive Staphylococcus aureus(MSSA) and Methicillin Resistant Staphylococcus aureus(MRSA), which causes serious hospital infection, and to apply them to antimicrobial finishing agents for textiles. Chitosan samples were highly deacetylated with sodium hydroxide solution and degraded with hydrogen peroxide to control the molecular weight. TMC has the antimicrobial activities against MRSA and MSSA. TMC showed an excellent antimicrobial activity below the molecular weight of 70,000, especially at 40,000. The minimum inhibitory concentration (MIC) of TMC with optimum molecular weight against MRSA and MSSA was 250ppm. Because MRSA did not resist TMC in the subculture test of bouillon medium, it was expected that the successive use of TMC against MRSA was possible.
A Study on the Dyeing Properties of Natural Indigo Complex Powder and Synthetic Indigo with Natural Fiber
Textile Coloration and Finishing, volume 12, issue 3, 2000, Pages 174~182
We prepared natural indigo/calcium hydroxide complex powder from tinctoria's leaf, according to the demand of developing new dyeing technique of natural fibre with natural indigo. FT- IR and UV/Visible spectra were operated to find the dyeing properties of synthetic indigo and natural indigo powder. Cotton, flax and silk fabrics were dyed with different pH, dye concentration and dyeing time. The colour yield of indigo dye was quite sensitive to dye bath pH and fabric. In synthetic indigo, the highest K/S value of dyed silk fabric was shown at near pH 9.0, and which of flax and cotton fabric were shown at pH 11.0. In other hand, in the case of natural indigo complex powder, the highest K/S value of dyed silk fabric was shown at near pH 8.0, and which of flax and cotton fabric were shown at pH 9.5∼pH 10. Mercerized cotton fabric dyed with natural indigo powder has a little antimicrobial activity.
Dyeing of Silk with Chinese Scholar Tree Extract
Textile Coloration and Finishing, volume 12, issue 3, 2000, Pages 183~191
The dyeing of silk fabric with chinese scholar tree extract was investigated. The colorant was extracted with distilled water, and concentrated under reduced pressure, and, finally spray-dried. The optimum temperature and dyeing time for the dyeing of silk with the scholar tree extract was
and 60 minutes respectively. In mordant dyeing, pre-mordanting method was most effective for color yield, and 1~2 % of mordant concentration was acceptable. Fastness of the dyed silk fabric to laundering and rubbing was shown to be good, but fastness to light, dry cleaning, and perspiration were varied with used mordants.
The Effect of Fluorescent Whitening Agents on the Whiteness and the Shade of Fabrics in Repeated Washings
Textile Coloration and Finishing, volume 12, issue 3, 2000, Pages 192~198
Influence of the fluorescent whitening agent(FWA)'s adsorption on the whiteness of cotton and on the color change of the dyed fabrics was investigated by repeating wash cycles. Cotton 100% and cotton60/polyester40 blended fabrics were dyed pink, blue and yellow, and cyanuric chloride diamino stilbene(CC/DAS) and distyryl bisphenyl(DSBP) were used for the FWA with laundry detergents. Fabrics were washed at
with Terg-o-tometer. The FWA adsorption amount was measured by the absorption intensity for the pyridine-water extracted solution. The FWA adsorption increased on the cotton fabric with the wash cycles. Though adsorption of CC/DAS continuously increased up to the 20th cycle, that of DSBP increased sharply before the 10th cycle and reached an equilibrium. The whiteness of the fabrics dried in the shade was greater than that dried under the sunlight through window glass. The color change of dyed fabrics was increased by the number of wash cycles. Pink changed more greatly than blue, yellow or grey cloth. The color change
of dyed fabric washed repeatedly up to the 20th cycle with the detergent without FWA was less than 1. It is recommended to wash pale colored fabric with the detergent free of FWA.
The Study of Natural Dyes on the Flowers(II) -The Dyeability and Antimicrobial.Deodorization Activity of Chrysanthemum boreale-
Textile Coloration and Finishing, volume 12, issue 3, 2000, Pages 199~206
Silk fabric was dyed using methanol extract of Chrysanthemum boreale at
for 40min. The K/S value of the silk fabric was highest in the premordanting method, while the amount of absorbed mordant was largest in the Cu-mordanting. The surface colors of the dyed fabric highly depended upon mordants or mordanting methods. For all cases, the value of the dyed fabric was dark. The chroma was high by using the Cr-mordant and the color difference was distinct by using the Fe-mordant. Cu-mordanted silk showed highest fastness to light. Dyed silk fabrics by mordanting method showed good antimicrobial activity ad deodorization property.
Assemblage and Driving Characteristics of a Ultrasonic Fabric Washing Machine
Textile Coloration and Finishing, volume 12, issue 3, 2000, Pages 207~217
A new, high-efficiency ultrasonic fabric washing machine was developed to be an energy-efficient washing machine and to enhance fabric washing quality in washing processes of the dyeing and finishing process in the textile industry. This system is composed of ultrasonic wave generator, air blowing nozzle, torque motor for fabric tension control, and enclosed washing bath, multi-tube type exchanger, noiseless heater, air cylinder, expander roller, mangle upper and lower rollers, bend bar, dancer, shower spray nozzle, and solenoid valve, and so on. These elements are synergised for fabric washing. One of the very important principles is the low tension fabric running system. For an efficient washing effect, a counter flow system is also adopted. The new system also adopts the dancer and torque motor to control fabric tension and prevent fabric creasing. Shower spray nozzle, counter flow and overflow apparatus, and air-blowing apparatus are adopted to enhance the fabric washing effect. In this study, peach yoryu, exter, and moss crepe fabrics were washed by the general and ultrasonic washing systems under different conditions respectively. The washing efficiency was affected by the fabric running speed and characteristics of fabrics. Size content after washing increased with increasing the fabric running speed. The values in the general washing system were higher than those of the ultrasonic washing system. The changes of conductivity in the ultrasonic and the cooling bath were affected by the running time under the ultrasonic generating. The values of conductivity decreased as the experimental time passed.
A Study on Color Treatment of Dyeing Wastewater with Bittern+Iron(II) chloride
Textile Coloration and Finishing, volume 12, issue 3, 2000, Pages 218~223
Color removal of dyeing wastewater is becoming more important due to intensive limitation on color unit of effluent water, so this study was to investigate an efficient color removal of dyeing wastewater. We found that bittern+iron chloride(II) inorganic coagulant developed by Kabool research center is much higher than any other inorganic coagulants for color removal. Optimum pH of this coagulant was 10.5 and removed more than 90% for color removal efficiency. The results showed that COD and color unit of effluent water was average 60mg/L and 200~250 units when continuous activated sludge test after coagulation with this coagulant has done. From the results of the experiments, the application of bittern+iron chloride(II) inorganic coagulant can save the operating cost of wastewater treatment plants.
