The tannin acid and the enzymes have been used in order to improve the ruggedness in laundry and the absorption of dyes and pigments in the textile industry for several years. The enzyme processing on the protein fiber minimizes the damage of the entire fiber and improves the dyeability by effectively modifying only the hydrophobic surface. This study tried out the structural observation by applying the Castanea crenata sieb. et. zucc. containing abundant tannin to the hair dyeing as the natural dyeing pigment along with Protease of Rhizopus sp. The dyeability was improved as compared to the dyeing using only the synthetic tanning and iron mordant. When the depth of pigment was higher in accordance with the surface observation, the enzyme dissolution had impact on dyeing and so the keratin layer on the hair surface. Accordingly, it was found that the appropriate depth was between 0.01 and 0.03%. It was estimated that 0.1% protease would treated within 30min. Consequently, it would cause the good reaction with the functional group of tannin pigment.

To overcome the harmful effects caused by conventional oxidative hair dyes, natural colorants becomes more popular in the hair dyeing. By extracting Sagassum fusiforme powders with aqueous alkaline solution as a solvent at 130℃ for 60 minutes, a fucoxanthin concentration of up to 216㎍/ml can be obtained. UV/Vis analysis was used to prove the presence of fucoxanthin in the extract powder. A K/S value of 23.8 can be obtained when wool fabrics were dyed with the extract at 120℃ for 60 minutes under pH 2. The color fastness properties of the dyed wool fabrics were very good as indicated by rating 4 for laundering(color change), rating 3 or higher for rubbing, and rating 5 for light irradiation. The dyed wool fabric was found to have antimicrobial activity against Staphylococcus aureus. The antioxidant and antimicrobial activity of the Sagassum fusiforme extract can be an effective functional hair colorant. Hair dyeing with the extract formulation at 45℃ for 40 minutes under pH 5 accomplished a K/S value of 8.9. The color fastness of the dyed hair showed rating 3 against light irradiation, which increased to rating 5 with after-mordanting of tannin acid.

Each cotton fiber is a unicellular hair collected from the seed of cotton plant. The fiber contains many convolutions along its length. Mercer was the first to suggest caustic soda treatment of cotton in commercial application. Mercerization has been commercially used since Lowe's suggestion to endow cotton with increased strength and affinity for dyes with additional properties such as fabric touch or luster. In this study, cotton fabric specimens were mercerized to investigate the changes in physical and mechanical properties pertaining to the hand or touch of fabrics. Physical properties were measured using the KES(Kawabata Evaluation System).

This paper is a study on the expression of Clothing and Textiles recorded in $\ulcorner$Genjimonokatary (원씨물어)$\lrcorner$. This book is a novel written by a Japanese sextant worked in the Royal Court around the year 1010. In this book, about 110 different kinds of Garments, Ornaments, Colors and Materials were mentioned. The results of this paper were as follows. 1. About the Garments 8f Ornaments ; All the Clothing and Textiles in $\ulcorner$Genjimonkatary$\lrcorner$ were reflections of the reality of that time. In the Clothing, Color, Textile and even Hair style, the Symbol of Buddism appeared. Many technical methods were developed in the garment shaping, dyeng and wearing methods. 2. About the Colors Sf Dyes; There were many kinds of Color SE Dyes described in $\ulcorner$Genjimonokatary$\lrcorner$. This means color was developed more than other elements in that period. Among them, gray and black colors were mentioned, this means Buddist Color was fashioned in that period. $\ulcorner$Kasaneno-irome (강색목)$\lrcorner$ was changed from Ungan (운간) that had been origined of China and Korea. But it became one of the Japanese Costume. That have some reasons, for instance, high materials could not be imported from other countris and many people were controlled by the Taboo of clothing (금제) so they wanted the better method, such as Kasaneno-irome. Many kinds of colors'name was origined from flowers and plants. It also represented the seasons. Yurusi-iro (청색) was meaning the permitable color to the popular people. Without the head word, Deep Color' and 'Pale Color' meant those things of the purple and red. 3. About the Materials IE Patterns : The materials imported from other country, China and Korea, were good in quality, but those produced in Japan were not good. There were many kinds of dyeing method, especially Srijome (신염) was very special and nice method in that period.

Henna is a natural colorant and has been used to dye hair, skin and leather since civilization began. It has reddish brown to orange shade. The major color components of Henna are Lawsone(2-hydroxy-1,4-naphthaquinone) and Luteolin (3',4',5,7-tetrahydroxy-flavone). In this study, various fibers containing the nitrogen component, especially used fur underwear, were dyed with Henna under various dyeing conditions, then dyeing characteristics, color fastness, and anti-bacterial properties were evaluated. from the results, Henna has good affinity to the chlorinated wool>wool>Pu/nylon>nylon>soybean>silk in decreasing order. The color fastness of the wool fabric dyed with Henna to washing, dry-cleaning, and perspiration showed 4-5 grade. The color fastness to light was 3rd grade. These results are relatively good comparing with other natural dyes. Moreover dyed fabric with Henna showed excellent antibacterial activity.

Background: Several potential risk factors have been identified for diffuse large B-cell lymphoma (DLBCL); however, epidemiological studies investigating the association between these risk factors and DLBCL have yielded inconsistent results. Objectives: To investigate potential medical, lifestyle, and environmental risk factors of DLBCL in Shanghai, China through a hospital-based case-control study. Method: One-hundred-and-forty-seven newly diagnosed DLBCL patients and 294 sex- and age-matched controls were recruited from 11 hospitals in Shanghai between 2003 and 2007. A standardized structured questionnaire was used to obtain patient data on demographics, medical history, family history, lifestyle, and environmental exposures. Conditional logistic regression models were used to estimate odds ratios (ORs), with 95% confidence intervals (CIs), for risk associated with each data category. Results: History of tuberculosis (TB) infection and "living on a farm" were positively associated with DLBCL (TB: OR=3.05, 95% CI: 1.19-7.80; farm: OR=1.82, 95% CI: 1.21-2.73). In contrast, taking traditional Chinese medicine was negatively associated with DLBCL (OR=0.36, 95% CI: 0.14-0.89). No significant correlation with DLBCL risk was found for any of the other potential risk factors (p>0.05), including but not limited to hair dyes, alcohol drinking, smoking, and home/workplace renovation within one year. Conclusions: Consistent with results from previous studies in other DLBCL case populations, traditional Chinese medicine appeared to have a direct or indirect protective effect against DLBCL. However, this study also identified a possible predisposition for DLBCL in TB sufferers and farmers.

Objectives: This study examined the reproductive health status and the work-related factors of female hairdressers. Methods: This study conducted by structured questionnaire from April 21th to May 20th. The study population of 316 were female hairdressers aged 15 to 60 years in Seoul. This study analysed the influencing factors, health related factors and work related factors on reproductive health using chi-square and multiple logistic regression analysis. Results: 1. The 81.7% of the subjects aged under 29 years have unhealthy behaviors. The 47% of hairdressers experienced smoking. Among the total, 37% of them answered they are smoking at present. Those results reveal their working conditions were very stressful to cope as young females. 2. The use of hair dyes(OR=2.89, 95%CI:1.17-7.12), counteractive solutions(OR=3.20, 95%CI:1.04-9.83) and not wearing protective gloves(OR=2.81, 95%CI:1.11-7.12) are significantly associated with menstrual pains. 3. The hairdressers not using perm liquids were three times as likely to report regular menstruation compared with the hairdressers using perm liquids. Wearing protective gloves also was associated with regular menstruation. Conclusion: This study revealed various risky working conditions of hairdressers was associated with their reproductive health. This study suggests that we should pay more attention to the protective working conditions for reproductive health. More comprehensive health management program including reproductive health for female hairdressers is required as well.
