김태년 한국의류학회 2001 한국의류학회지 Vol.25 No.1

We have treated polyester fabric with CF_4, C_2Fe, SF6 and C3F6 glow discharge plasmas to develop functional fabrics which preserve moisture transportation and water proofing nature. Modified properties were evaluated by water vapor permeation rate and breakthrough water pressure. The change of surface morphology was observed by SEM. Fiber interstice of the plasma treated fabric was calculated as 0.32㎛, and this value was sufficiently ideal as water repellent material. The moisture transportation of CF_4 treated fabric was good as much as untreated fabric, and those of C_2F_6-treated, SF_6-treated fabrics were reduced by 1∼3%, and that of C_3F_6-treated fabric was reduced by 15%. The best treatment condition were 0.06 torr 120 seconds in CF_4, 0.05 torr 30 seconds in C_2F_6, 0.08∼0.15 ton 90 seconds in SR and 0.1 ton 45 seconds in C_3F_6 respectively. The grade of moisture transportation effect was CF_4>C_2F_6>SF_6>>C_3F_6, and water proofing effect was C_2F_6◁그림삽입▷(원문을 참조하세요)CF_4>C_3F_6>SF_6. It was observed by SEM that the thin film was formed on the surface of the treated substrate by the fluorocarbon plasma treatment.

水溶性 高分子助劑에 의한 織物에의 Calcium鹽 沈着妨害效果(Ⅱ) : 夏節用 各鍾 麻混紡織物 Linen and Ramie Biended Fabrics

金泰年 又石大學校 1989 論文集 Vol.11 No.-

The influence of the water-soluble polymer builders on calcium deposition on the fabric was studied by repeating laundering the linen and ramie blended fabrics with sodium dodecylbenzen sulfonate(NaDBS) in hard water of 300 P.P.M. CaCO_3. The polymer builders were used sodium carboxymethyl cellulose (NaCMC) and polyvinylalcohol(PVA). The amounts of calcium deposits on the fabrics were determinded by EDTA-Back-titration methods. The results of this study were as follows: 1. By increasing the polymer builder concentration, the amounts of calcium deposits on all blended fabrics were decreased. In the case of PVA, calcium deposition on the polyester blended fabrics was prevented remarkably. 2. It is concluded that the preventing action of PVA is not ascribed to PVA adsorbed on the fabrics but to that dissolved in aqueous solution, and that of NaCMC is ascribed to NaCMC adsolbed on the fabrics and the calcium particles 3. It seemed that the prevention effect on calcium deposition on the fabric was due to complex formation between polymer builder and NaDBS, and that becames most remarkably at a critical micelle concentration region of NaDBS. 4. As the water hardness increased, the amounts of calcium deposition on all blended fabrics were increased, however the prevention effects of polymer builders were maintained.

The influence of water-soluble polymer builders on calcium deposition on the fabric was studied by repeated laundering the various fabrics with C_16TABr in the hard water. The amounts of calcium deposits on the fabric was dertermined by EDTA-BACK titration methods. The results of this study were as follows; 1. The amounts of calcium deposits increased with increasing wash cycles, however dissimilarily properties in each fabric was recognized. 2. By increasing the polymer concentration, the amounts of calcium deposits on the fabric was decreased, and this time PET-PVA and Cellulose-NaCMC were more effectively prevented on calcium deposition than PET-Na-CMC and Cellulose-PVA. 3. By increasing the C_16TABr concentration, the amounts of calcium deposits on the fabric was decreased remarkably. 4. It seemed that the prevention effect on calcium deposition was due to complex of poly-mer-C_16TABr and adsorption of C_16TABr and adsorption of C_16TABr on the fabric. 5. Stiffness of the fabrics were increased with addition of polymer builder in C_16TABr laundering system, and this time desirable concentration was about 0.05-0.08g/100㎖. 6. Crease recovery of the fabrics were decreased with addtion of polymer builder in C_16TABr laundering system.

金泰年 又石大學校 1984 論文集 Vol.6 No.-

The purpose of this study was to investigate the effect of the water-soluble polymers on the removal of deposited calcium on the cotton fabric. The polymers were used sodium carboxmethyl cellulose (Na CMC) and poly vinyl clcohol(PVA). The amount of calcium deposits on the fabric was determined by EDTA-back titration methods. The results of this study were as follows: 1. By increasing the polymer concentration to 0.05g/100ml, the amount of calcium removal was increased, and Na CNC was more effective than PVA. 2. It seemed that the increase of the rate of calcium removal was due to complex formation between polymer and Na DBS. 3. When water-soluble polymer was used, the pH, added alkaline builders and temperature of washing solution did not influence on the removal of deposited calcium on the cotton fabric. 4. The tate of calcium removal was increased with increasing concentration of STPP as sequestering agent. At high concentration of STPP, however, the rate was rather decreased with increasing concentration. 5. The amount of calcium removal was increased with increasing wash cycle to 3 times.

Costume has expressed the life style and influence on natural and social environment, The purpose of this study is to understand changes of hair style and millinery life in the west. The data used in this study included in the literature on this subject. The research results can be summarized as follows. 1. A hair style of ancient times was frizz or chignon or dyed hair style. Sometimes, they wore wigs of false hair, or put on a head kerchief. Millinery has been not worn until then. 2. In the middle ages, the hat serve to symbolize the social rank or authority or religion. Turbans were worn which concealed the hair. The hair style were large stuffed rolls over which the wimple was sometimes draped. These stuffed rolls were also used to form some shapes of the hennin, principally the heart-shaped and circular cone style. The hennin was brought to France by Isabella of Bavaria in the latter part of the fourteenth century and its vogue lasted a hundred years. There were many styles of the hennin, invariably draped with a veil, floating or with wired edge. They became so extravagant in size that I found it necessary to regulate the height according to the socal position of the wearer.
