This study examined the stainability and functionality of cotton dyed with the extract of Salvia Plebia R. Br. as a research preceding the development of health functional materials and fashion products with a healing motif. The CIELAB measurements of the cotton fabric dyed with the extract of Salvia Plebia R. Br. showed 73.32 for $L^*$, 1.7 for $a^*$, and 37.78 for $b^*$, while the Munsell measurements exhibited 2.63Y in color, 7.18 of brightness, and 5.49 of chroma. The degree of staining resulting from color fastness to laundering, and that resulting from color fastness to perspiration (acid and alkaline), as well as the level of color fastness to crocking (wet and dry) all stayed between relatively higher levels of 4 and 5. The fabric dyed also exhibited SPF 50+, an outstanding sun blocking performance. The deodorization rate was also excellent, rising from 97% to over 99% when the time elapsed increased from 30 minutes to 120 minutes. The fabric dyed also showed a 99.6% antimicrobial activity against staphylococcus aureus ATCC 6538, and a 71.4% antimicrobial activity against Klebsiella pneumoniae ATCC 4352. The aforementioned findings indicate that fabrics dyed with the extract of Salvia Plebia R. Br. contain the potential to be developed for use as health-related materials and fashion products that promote healing.

The purpose of this paper is to investigate the dyeability, antibacterial activity, and deodorization of cotton and silk fabrics dyed with extracted solution from Chrysanthemum boreale. The results are as follows： 1. The optimum conditions of dyeing temperature and time for the cotton fabrics were 90$^{\circ}C$ and 60minutes, while those of the silk fabrics were 60$^{\circ}C$ and 30 minutes respectively. 2. The K/S values of cotton fabrics were slightly higher than those of silk fabrics. The K/S values of both fabrics were slightly increased by mordanting with Cr but were decreased by mordanting with Cu and Fe 3. The colors of the cotton and silk fabrics changed from GY to Y. In both cases, the values of the fabric colors were lowered, and the values of the colors continued to be lowered with Cu and Fe. The chroma and color difference of both fabrics were high and were further increased by mordanting with Cu. 4. The fastness to dry-cleaning and rubbing of the cotton and silk fabrics was very good. The fastness to washing of both fabrics was good except when mordanted with Fe. The fastness to perspiration of both fabrics was fairly good, but the fastness to acid perspiration was poorer than that to the alkaline perspiration. The fastness to light of both fabrics was very poor. 5. The cotton and silk fabrics showed excellent antibacterial activity. Both fabrics mordanted with Cu showed perfect antibacterial activity. 6. The deodorization of the silk fabrics was very good, and that of the silk fabrics mordanted with Cu and Al was excellent, while the deodorization of the cotton fabrics was fairly good.

천연염색은 자연의 식물, 광물, 동물 등에서 염료를 추출하여 직물에 착색하는 것을 의미한다. 합성염료가 발명되기 이전까지 천연염료를 이용하여 의류 및 생활용품 등의 직물에 염색을 하고 인체에 장식을 하였다. 천연염색 중 대부분은 식물성 염료로서 식물의 껍질, 줄기, 열매, 뿌리 등으로부터 색소를 얻을 수 있다. 이러한 천연염색은 그 색상이 차분하고 은은하며, 생리적 측면에서 항균성, 소취성이 있으며, 염색공정이 환경친화적인 저공해 염색으로 알려져 있다. (중략)

콘크리트의 내화성능에 대한 다각적인 연구가 1970년대부터 원자로의 안정성 확보차원에서 진행되어 왔으며 특히 콘크리트의 취성파괴(brittle failure)등에 대한 연구가 많다. 콘크리트의 내화성이란 화재로부터 보호되고 고열환경에 견디는 재료적 특성 즉 화재온도 1,00$0^{\circ}C$ 정도의 고온을 30분에서 3시간 정도를 받은 경우 콘크리트 중에 매립된 철근 등 철강을 소정의 온도 이하고 유지하기 위한 피복 역할을 유지하면서 구조물의 큰 변형이나 붕괴 등을 막기 위한 소요 압축강도 및 영계수 등의 성능을 가지고 있는 성질을 말한다.(중략)

The merits of activated carbon for removal of organic compounds have been well known in the various industrial fields. Fixing methods with activated carbon in the non-woven fabric have the advantages of fast adsorption and ease of handling when compared with bonding and coating methods. In this study, we have examined deodorization of non-woven fabrics fixed with activated carbon. We have been tested the deodorization of various kinds activated carbon and non-woven fabric structures. The effective mixing ratio of activated carbon was 5% on the weight of fabrics, which are closely related to the fabric structure. The activated carbon with higher mesh size show the better deodorization effect.

The purpose of this study is to examine the antibacterial activity and deodorization of fabrics dyed with pine needles extract. The microbes used for a test were two kinds of bacteria and two kinds of fungi. The test results showed as follows. In the test results of antimicrobial activity, both cotton and silk fabrics showed the antimicrobial rate of over 90% after washing three times. In the test result of antifungal activity, all fabrics didn't show any effective antifungal activity. In the test result of deodorization, the dyed cotton fabric showed the higher rate of deodorization than the non-dyed fabric, and the fabric showed the highest rate of deodorization was the test fabric mordanted by Fe and the rate of deodorization showed 92%. In case of silk fabric, the fabric showed the highest rate of deodorization was the test fabric mordanted by Al, and the rate of deodorization showed 92%.

Using water and methanol, the colorant components were extracted from the heartwood of amor cork tree which is known as the oldest natural yellow dye. The dyeabilities of the colorant on cotton and the fastness of cotton fabrics dyed with amur cork tree extracts were investigated. According to the dye uptake and mordant concentration, antibacterial activities and deodorization properties of dyed fabrics were also investigated. As a results, K/S values of dyed fabrics were increased with concentrations of mordants and amur cork tree extracts. Washing fastness of dyed fabrics was very low, light fastness was fair and the other fastness were good. Deodorization rates of dyed fabrics were increased in proportion to concentrations of amur cork tree extracts. The reduction rates of bacteria measured by Bioassay tests were also increased in proportion to concentrations of mordants and amur cork tree extracts.

Silk fabric was dyed using methanol extract of Chrysanthemum boreale at $60^\circ{C}$ 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.

Silk fabrics were dyed with Gromwell extracts after mordanted with various mordants and their dyeability, antibacterial.deodorization activity, fastness and change of surface color were investigated. Silk fabrics were mordanted at $60^\circ{C}$ for 30 minutes and subsequently dyed at $40^\circ{C}$ for 30 minutes. The dye-uptake of silk fabrics increased with the concentration of Gromwell extracts and mordants. Surface color of silk fabrics changed differently according to the type of mordants used. Antibacterial and deodorization activities of silk fabrics dyed with Gromwell extracts were good. Cu mordant was more effective for deodorization activity. Dyed silk fabrics showed poor light fastness but good dry-cleaning and perspiration fastness.

단파장 자외선을 이용하여 폴리에틸렌테레프탈레이트(PET) 섬유 표면의 화학적 성질을 개질 하였다. 자외선 조사에 의하여 PET 섬유의 화학결합이 절단되어 섬유표면에 COOH기가 생성되고 자외선 조사시간에 비례하여 COOH기가 증가함을 FT-IR과 XPS 분석에 의하여 확인하였으며 XPS측정을 통하여 PET 섬유 표면에 생성된 COOH기가 12개월후에도 변화가 없음을 알 수 있었다. 또한 자외선 조사 PET 섬유에 기능성을 부여하기 위하여 사용한 친수성의 양이온성 천연화합물이, 자외선 조사 PET 섬유에 용이하게 흡착되는 현상으로부터 자외선 조사에 의하여 PET 섬유표면에 음이온성을 나타내는 COOH기가 존재함을 흡착실험을 통하여 확인하였다. 항균성 및 소취성을 측정한 결과 자외선 조사시간이 30분 이상인 경우에 99% 이상의 항균성과 75% 이상의 소취성을 나타내는 기능성 PET 섬유의 제조가 가능하였다.
