To investigate the soil-redeposition and color change on dry-cleaning, the white and dyed fabrics of cotton, silk, polyester and viscose rayon were put into ordinary commercial dry-cleaning machine with soiled cloths. The solvents used were hydrocarbon, perchloroethylene and fluorocarbon. From the result, we obtained the following conclusions by examining soil-redeposition, color difference of fabrics and tenacity of cotton fabric. 1. In case of white fabrics, as a whole, perchloroethylene shows the lowest soil redeposition. When distillation process is adopted, the rate of soil redeposition is lowered. with hydrocarbon sdvent. The order of soil redeposition rate of fibers are following; cotton> viscose rayon> silk> polyester. 2. In case of dyed fabrics, the color difference between soil redeposited fabrics and originals (Δ E,) is similar with white fabrics in pattern, and the order is cotton, viscose rayon, silk and polyester. The color difference between fabrics, treated by pure solvents and originals (Δ E₂2) is also validated as a little. It seems to be due to the bleeding of dyestuffs from fabrics. 3. There is a little change of tenacity of cotton fabrics by dry-cleaning with perchloroethylene solvent. It is supposed that the damage is more influenced the repetitive mechanical action during dry-cleaning than by acidity of the solvent having the acid value of 0, 14.

The purpose of this study was to study accumlated residual soils which may be one of the causes for yellowing of worn cloths. Wear and wash tests of white cotton undershirts were repeated at 30 households sellected at random over a period of 60 days. Laundry conditions were similar to home laundry habits in a fact-finding survey, using a powdery heavy duty detergent containing no enzymes or enzymes. The subjects in this study were survey of laundry actual condition, the undershirts from prior to and after the final washing was measured residual soils, L*a*b* value and yellowness index of CIE systerm. Data were analysed by simple correlation analysis of wear and wash cycle, residual soils, whiteness. The results obtained were summarized as follows: 1. Using pattern of washing machine, Presoaking was no singinificant differnece in general characteristics of survey respondent. Laundry frequency was significant difference in income level, occupation of housewives whether or not. Use of cold and hot water was significant difference in residence shape. 2. The analyzed consequences of recognition and actual behavior in connection with laundry were found variables each other to have independence or not. 3. Amount of residual sebum soils is using non-enzyme detergent were much more than in using enzyme detergent, increased linearly with increase of the number of wear and wash cycles. 4. Residual protein soils with increase of the number wear and wash cycles less than increase of residual sebum soils. Protein soils in white cotton undershirts was to be removed in laundering more easy than sebum soils. Since accumulated residual sebvum soils were much more than residual protein soils. 5. Increase of residual soils was raised yellowness index and diminshed whiteness. yellowness index of residual sebum soils was higher than protein soils. If increase of whiteness will be incresed, amount of residual sebum soils will be decreased sebum soils. Because amount of residual sebum soils much more than protein soils, yellowness index of residual sebum soils was more higher than that of protein soils.

Figured gold foil has been used in Korean clothings for a long time. It is one part of the clothings as a trimming. But with it's partial omission in wearing or cleaning, it leads to a potent influence on the dignity of garments as a whole-i.e., it results in the shortage of clothing's external life span. So, the examination of figured gold foil is in need from the aspect of consumption. In this study, the colorfastness was tested from the figured gold foil used in general. And it was done from the figured gold foil adhered by Chloroprene or Acramine for adhesive.

차옥선 한국섬유공학회 1986 한국섬유공학회지 Vol.23 No.6

Detergency effect was analyzed in terms of interfacial-chemistry parameters of rolling-up effect. Polyester film was used for substrate, the mixture of liquid paraffin containing 5% oleic acid was used for oily soil and LAS alone and the mixed of LAS and nonylphenol polyoxyethylene ether having various mole numbers of ethyleneoxide adducts were used for surfactants. The removal process in a form of droplet was analyzed by measuring interfacial tension at oily soil and surfactant solution, contact angle between substrate and oily soil. Interrelationship between the detergency and the rolling-up was also examined by washing artificially-soiled fabric in those surfactant solution. The results showed that the oily soil was more easily removed with lower interfacial tension at oily soil and surfactant solution and with larger maximum contact angle at equilibrium state. In comparison LAS with mixture of surfactant solutions, performance of the mixed solution was better than of LAS alone. In case of mixed solution, the solution with the higher content of nonylphenol polyoxyethylene ether, the lower interfacial tension and the higher maximum contact angle were observed.

The indigo-dyed blue denim garments are favored not only by young people but also by almost everyone of life. In the early years they were casually worn on most occasions, but became universal recently. Such denim garments are treated with various process to give it optimal softness and color contrast of blue and white. The processes can generate photoyellowing, and thus the yellowing may damage their appearance and quality. So, this study is to find the solutions to reduce the photoyellowing problem. For this purpose, sample denim were treated with cellulase, fluorescent brightener, UV absorbent etc.. The results were as follows; The yellowing would be more accelerated by fluorescent brightening. Since the yellowing was caused by daylight, several UV absorbents were applied to prevent the yellowing caused by daylight. As a result, the yellowing was reduced by 90%. In particular, the application of the UV absorbent before using of the fluorescent brightener was most effective. The optimal concentration was 0.5%(o.w.f), and the benzophenone compounds were found most effective for the indigo denim. And reduction effect of yellowing by UV absorbent was lowered with repeated laundering, but metal compound treatment on fabric made a removal of UV absorbent by laundering prevented.

This study was performed to investigate the effect of mordants on the dyeability, colorfastness to light and to laundering and biological properties of mordanted and natural-dyed cotton and silk substrates. Natural red dyes were extracted from Caesalpinia Sappan L.(Sappan wood) and Rubia Akane Nakai(Madder) by boil water. Five different compounds of Al, Cr, Cu, Fe and Sn were used as mordanting agents. The result of this study are sumarized as follows 1. In the case of the fabrics mordanted and dyed with sappan word, K/S value increases and λmax shifts to the longer wavelength as mordant concentration increases. Color of the fabrics dyed with sappan wood and madder change to redder, bluer and lighter after mordanting. 2. As the number of repetition of dyeing-mordnating process increase, the color of the dyed fabrics tend to be redder, bluer, and darker. Mordanted dyes with Al and Sn make chroma increase. The quantity of mordant absorbed in the silk fabric increase as mordant concentration increase. More Fe is absorbed in silk than Cr is. 3. After being exposed to light, the fabrics dyed with sappan wool and madder change to less red. Fe and Cu mordanting yeild better colorfastness to light than others does. Natural--dyed fabrics exposed to light tend to be faded and whitened in a CIELAB chromaticity co--ordinates. So, we might trace back the original color of ancient faded fabrics by changes in color of natural dyes. 4. After washing, the colors of natural dyes change to more blue. Fe and Cu mordanting give better colorfastness to wash than others do, 5. The soil--burial cotton is more susceptible to mildew and rot than the silk is. Antimicrobial activity of the natural-dyed cotton can be enhanced by Cu and silk can be enhanced by Cu and Cr mordanting respectively.
