The purpose of this study is to investigate the dyeability of crabyon fiber contained cotton towels after dyeing with gallut. In this study, the colorants of gallnut were extracted with boiling water at 60℃ and 60min. Crabyon, composite fiber of Chitin/Chitosan and cellulose, is manufactured by uniformly blending Chitin/Chitosan and cellulose viscose and extruding the blended viscose into spin-bath. Cotton towels with crabyon fiber dyed with extracted solution from gallnut according to concentration, temperature and time. Crabyon fiber contained cotton towels dyed using gallnut were pre of post-mordanted using Al, Cu, and Fe. The dyeability(K/S) and color characteristics(L^*, a^*, b^*, C, and h(color angle)) of dyed crabyon fiber contained cotton towels were measured by computer color matching machine and photographs. The crabyon fiber composition of cotton towels was conformed by amide peak(-CONH-) of chitin or chitosan of FT-IR spectroscopy. The results obtained were as follows; The amide peak of crabyon fiber contained cotton towels appeared at about 1652 cm⁻¹. The dyeability of crabyon fiber contained cotton towel was increased gradually with increasing concentration of gallnut dyeing solution and saturated at about 150%(o.w.f). The optimum dyeing temperature and dyeing time were 90~100℃ and 80minutes expectively. The crabyon fiber contained cotton towels were dyed reddish yellow by non, Al, and Cu mordanting, reddish blue by Fe mordanting, respectively. The fastness to washing according to concentration of gallnut in and mordanting method indicated good grade result as more than 3~4 degree in all conditions.

Cocoa is a popular drink for children and contains healthy polyphenols however; a deep brown stain is left when cocoa is spilled over clothes. The main pigments in cocoa are anthocyanins that change in washing solutions with different alkalinity and metals. The removal and color changes in a cocoa stain after washing with various pH solutions and water hardness were studied. Alkalinity and the water hardness of washing solutions were important factors for the removal of cocoa stains. The removal of cocoa things in washing solutions without detergent was low (and even became negative after removal and darker) in solutions with a pH 9 and above. The cocoa stain was not removed and only the fabric color faded, although the cocoa stained cloth was washed with Korea tap water that has a pH of 7. The cocoa stain removal in detergent solutions was conspicuously higher than for only water. Even in detergent solutions, the cocoa stain removal decreased as water hardness increased. Cocoa stain removal was more effective and the color dimmest when the stained cloth was washed in a solution without the metal cations, and the bleach added with the detergent at a temperature of $40^{\circ}C$ and for longer than 20 minutes. Effective and economical equipment for tap water softening for a washing machine should be developed and used to improve cocoa stain removal.

세탁세제 빌더로 사용되는 제올라이트 A는 수용액 내에서 다가 이온의 이온교환 작용을 발휘하여 세정효과를 높여주고 물에 불용성인 물질로서 수용액 내에서 콜로이드 입자로 존재하므로 그 세정효과를 콜로이드의 분산안정화 이론을 이용하여 정량적으로 측정할 수 있다. 본 연구에서는 제올라이트 A의 입자오염에 대한 세정성능을 상호작용의 포텐셜 에너지 관점에서 평가하고자 각각의 무기염 용액 내에서 카본블랙, 셀룰로오스 및 제올라이트 A의 제타 포텐셜을 측정하고, 헤테로 응집이론에 적용하였다. 제올라이트 A는 탄산나트륨 용액 내에서 섬유 입자와의 정전기적 반발력을 상대적으로 크게 하여 세정효과를 높여주며, 황산나트륨 용액 내에서는 카본블랙과 급속응집을 일으켜 카본블랙이 섬유에 재 부착되는 정도를 낮추어주는 역할을 하는 것으로 판단된다.

In this research, the curly dock was used in the process of dyeing for fabrics of the inner wear & the patient wear. Since the curly dock has a pharmacological effect on dermatosis, this study focused on the variety of color and functions of the inner wear fabrics & patient wear fabrics to make the best use of the pharmacological effect of curly dock. With regards to giving a variety of colors and functions in the inner wear, patient wear fabrics, the curly dock dye was used in each treatment conditions on the cotton & silk fabrics. After dyeing, the dyeability, color change, light fastness, washing fastness, perspiration fastness, antibiosis, far infrared emissivity and emission power were evaluated. The evaluation results are as follows; The dyeablity increased from repeated dyeing and, by using the mordant, variety of colors such as skin, mustard, greyish-brown and dark earth colors were conformed to the naked eye. Fe mordant was better than Al on the lightfastness and the washing fastness. The repeated dyeing was found out to have less effect on neither lightfastness nor washing fastness. Both silk and cotton fabrics were graded $3{\sim}4$, since their degree of degradation appeared to be the same in alkali perspiration and acidic perspiration. In the case of silk fabrics mordanted by Al, the rate of declining in both Staphylococcus aureus ATCC 6538 and Klebsiella pneumonia ATCC 4352 were 99.9%. In addition, the antibiosis was enhanced when the mordant was used. The far infrared was 86.6% of emissivity, $3.34{\times}10^2\;W/m^2{\cdot}{\mu}m$ emission power.

Objectives : This study aims to design a method for drying forceps jars. As part of the process, holes were made in the forceps jars. Drying time, rate of wet pack, and cost of rewashing linen were then determined. Moreover, the study looked into the bacteria incidence rate in the forceps jars. This study suggests a practical way for preventing infection in a hospital through a surgical device. Methods : This study investigated the effect of forceps jars with holes on reducing drying time, rate of wet pack, and cost of rewashing linen. It also looked into the bacteria incidence rate in the forceps jars through a parallel design. Data was collected and analyzed using SPSS version 21. Results : The drying time of a forceps jars was remarkably reduced from $18.44{\pm}0.2$ minutes(non-hole forceps jars) to $0.58{\pm}0.02$ minutes(4-hole forceps jars). The rate of wet pack of non-hole forceps jars was 51.4%. However, the rate of 4-hole forceps jars reached 4.6%. The cost of rewashing linen saw a decline from 38,073 won to 3,381 won. In addition, no bacteria and virus were detected from the 24-hours usage of forceps jars even though the jars had holes. Conclusions : The 4-hole forceps jars greatly increased work efficiency as a result of the reduced drying time, rate of wet-pack and cost of rewashing linen. The 4-hole forceps jars did not influence their sterilizing effect.

The dry cleaning effect related to the type of soil and fiber was analyzed using silicone and alcohol-based solvents(ethyl alcohol, isopropyl alcohol, acetone) that are relatively safe for the human body and environment to improve the detergency of hydrophilic soils in dry cleaning system. Based on this analysis, an effective dry cleaning method to be carried out for improving the detergency according to the type of hydrophilic soils. After dry cleaning was performed using 20 types of artificial soiled fabrics consisting of 7 types of fibers and 4 types of hydrophilic soils, the detergency was measured and the results were compared and analyzed by solvents and fiber types. The results are presented as follows; first, the detergency of hydrophilic soils using silicone solvents showed a low rate of detergency. In particular, the tannin soil showed a lower level of detergency compared to the protein soil. Second, the detergency of hydrophilic soils using silicon solvents with dry soap differed in some detergency according to the soil and fiber types. Especially, the detergency of curry soil on cotton fabric showed significant improvement. Third, the protein soil was not removed from dry cleaning using alcohol-based solvents, but the effect of dry cleaning of curry soil on both cotton and polyester fabric was substantially improved. As a result, the elimination of blood soil is more effective in silicon solvents than in alcohol-based solvents. The removal of tannin soils may improve detergency by adding dry soap to silicon solvents or by using alcohol-based solvents as alternative solvents. The use of alternative solvents such as silicon and alcohol solvents can contribute to the environmental improvement of the dry cleaning industry, which uses petroleum-based solvents. It is also expected to provide consumers with the opportunity to choose eco-friendly and efficient dry cleaning methods.
