오늘날 인간 생활에서 섬유제품은 인체와 가장 많이 접하고 있어서 인체의 분비물과 함께 미생물이 서식하여 인체 건강을 해치거나 악취를 발생시킨다. 이러한 현상은 섬유제품을 변색, 오염, 손상시키므로 항균, 소취성있는 섬유제품이 요구된다. 또한 섬유제품에 처리된 항균, 소취가공제는 안전성이 요구되며, 동시에 자연계에서 간단히 분해되고 유해물질을 생성하지 않아야 한다. (중략)

$\beta$-Cyclodextrine/benzoic acid complex was prepared and reacted with cyanuric chloride (2,4,6-trichloro-1,3,5-triazine). Identification of complex formation and reaction was checked by FT-IR, UV-Vis, and EDX. By reacting this material with cotton fiber, the deodourant fiber was prepared. The deodourizing property was evaluated by the concentration changes of aqueous ammonia solution after flowing ammonia gas through the column titled with deodourant fiber prepared. The deodourizing property was increased with an increase of concentration of $\beta$-cyclodextrine unit in the fiber. In the case of $\beta$-cyclodextrine/benzoic acid complex, the deodourzing property was much increased, comparing with the $\beta$-cyclodextrine only. It was considered to be the binding of aamonia gas caused by benzoic acid in the complex.

This study shows the colorfastness, antibacterial activity, and deodorizing effect about cotton and silk fabrics dyed with Lithospermi Radix Extract. In the case of colorfastness, the light colorfastness showed the lowest grade, the other colorfastness was relatively good. However there are some differences according to fabrics and mordants. In the case of antibacterial activity to Staphylococcus aureus, the cotton fabrics had the most antibacterial effect at the dyed fabrics that had been mordanted SnC1$_2$ㆍ2$H_2O$, and the silk fabrics had the most antibacterial effect at the dyed fabrics that had been mordanted A1($CH_3$COO)$_3$. In the case of deodorizing effect, the cotton fabrics showed the most deodorizing effect at the dyed fabrics that had been mordanted SnC1$_2$ㆍ2$H_2O$, and the silk fabrics showed the comparatively high antibacterial effect at the dyed fabrics that had been mordanted both SnCl$_2$ㆍ2$H_2O$ and Al($CH_3$COO)$_3$.

The purpose of this study is to investigate the dyeability, antibacterial activity and deodorization on cotton and silk fabrics dyed with extracted solution from gardenia. The results are as follows: 1. The K/S value of silk fabrics was higher than that of cotton fabrics, and the K/S value was slightly increased by mordanting with $SnCl_2.2H_2O$ and $K_2Cr_2O_{7}$ on cotton and silk fabrics. 2. Cotton fabrics showed yellow from GY to Y and silk fabrics showed yellow or reddish yellow from GY to Y-YR. 3. The fastness to washing of cotton fabrics was very poor and that of silk fabrics was middle or lower, excluding good fastness to wool contamination of both fabrics. The fastness to dry cleaning and rubbing of both fabrics was very good. The fastness to perspiration of cotton fabrics was middle or higher, but that of silk fabrics was much better than that of cotton fabrics. The fastness to the light of both fabrics showed very poor with 1 grade. Dyeing fastness was slightly improved by mordanting on both fabrics. 4. Silk and cotton fabrics did not show antibacterial activity, but the activity of silk fabrics was higher than that of cotton fabrics. The antibacterial activity was increased by mordanting. 5. The deodorization of dyed cotton and silk fabrics was excellent, and that of silk fabrics showed better than that of cotton fabrics.

In this study, characteristics of effect on hydrogen gas was investigated to hydrogen embrittlement by disk and tensile tests. The developed and commercial alloy was fabricated to a plate material made from an alloy ingot. The prepared materials were processed in the form of a disk to measure rupture pressure by hydrogen and helium gas at a rate of 0.1 to 1,000 bar/min. In the hydrogen pre-charged tensile test, a specimen was hydrogenated using an anode charging method, and the yield strength, ultimate tensile strength, elongation, and reduction in area rate were carried by a strain rate test. Also, the microstructure was observed to the fracture surface of the tensile test specimen. As a result, the developed materials satisfied endurable hydrogen embrittlement, and the fractured surface showed a brittleness fracture surface with a depth of several ㎛, but dimple due to ductile fracture could be observed.

감, 밤껍질, 포도, 숯, 쪽, 오배자로 빛깔을 내는 천연염색. 홍루까(54세) 쪽염색 염색가는 자연의 재료를 모아 건강한 색을 만든다. 천연염색은 인위적으로 만들어낸 색과 다르게 자연을 보는 듯한 자연스러움이 있고 항균성, 소취성, 항알레르기 등 건강한 기능까지 가지고 있다. 지난 10월 18일 한복아카데미에서 천연염색 강의를 진행하고 있는 홍루까 염색가를 만나 천연염색에 대한 이야기를 들어봤다.
