Skin colors of the females of Hanoi and Ho Chi Minh City of Vietnam between the age of 25-35 were measured using the Minolta CM- 600d spectrophotometer. Face and body colors represented by CIELAB Lab values and Munsell HVC values were analyzed using t-test, Linear regression analysis, and K-Means cluster analysis by SPSS software. There were statistical differences between the face and body colors of Hanoi and Ho Chi Minh City females. Forehead and left cheek colors of the Hanoi females were yellower than those of Ho Chi Minh City females. The neck of Hanoi females were darker and had more yellow. The Higher Lab value of face color, was higher the body Lab in face and body relationship. In particular, the b value of face gave the most effect to body yellowness in Hanoi and the L value of face gave the most impact to body brightness in Ho chi minh. Skin colors of the regions were divided into three group by CIE Lab value. Type 1 had the highest brightness and lowest yellowish red. Type 2 had middle Lab value. Type 3 had the highest darkness and yellowish red. Many Hanoi women belonged to Type 2(59%) while Ho chi minh women showed an similar distribution of Type 1(39.2%) and Type 2(42.2%).

Skin colors of females between the ages of 25-35 from Korea, China, and Vietnam were measured in Seoul, Beijing, and Hanoi using the Minolta CM-600d spectrophotometer. CIE Lab and Munsell HVC data of the face (forehead and both cheeks) and body (neck and arm) were analyzed using t-test, Analysis of Va-riance (ANOVA), Duncan`s Multiple Range Test, Linear Regression Analysis, and K-Means Cluster Analy-sis using SPSS software. Korean females showed the highest L and V values for the face and body; Vietna-mese females showed the highest b value in the face and the highest a value in the body. Higher L and b values for the face were related to higher L and b values of the body; this relationship was more prominent in Korean females. The younger age group (25-29) showed higher L values and lower b values than the older age group (30-35). Females from Korea, China, and Vietnam were grouped into Type 1 and Type 2 based on skin color. Type 1 had darker skin with more redness and yellowness and Type 2 had lighter skin with less redness and yellowness. A total of 88.2% of Korean females belonged to Type 2, 80.4% of Viet-namese females were Type 1, and Chinese females indicated an even distribution of Type 1 and Type 2.

인디고 및 인디루빈 표준 혼합염료에서 인디고틴과 인디루빈 색소가 견직물에 대한 염착성과 색상에 미치는 영향 연구

유완송,안춘순,Yoo, Wansong,Ahn, Cheunsoon 한국의류학회 2017 한국의류학회지 Vol.41 No.5

This research investigated the effect of pH of dyebath and dyeing temperature on the dyeability of indigotin and indirubin on silk as well as the relationship between the amount of indigotin and indirubin detected from the dyed silk through HPLC-DAD analysis and the color of samples measured using a spectro-colorimeter. Indigo standard dye and indirubin standard dye were deliberately mixed by ratios 100:0, 80:20, 60:40, 40:60, 20:80, and 0:100 to dye silk with a different pH of dyebath (7, 11) and different dyeing temperatures ($50^{\circ}C$, $70^{\circ}C$). The amount of indigotin and indirubin pigments in silk was calculated using regression equations obtained from standard calibration curves of indigotin and indirubin. A higher indigotin percent ratio resulted in the higher K/S values and the higher amount of indigotin detected from silk. However, higher indirubin percent ratio in the mixed dye did not relate to the higher indirubin pigment detected in silk. While indirubin showed low or negative contribution to the K/S values, it showed a higher effect on the color of dyed silk. Higher amounts of indirubin in dyed silk resulted in a darker PB color, which led to P color with increases in indirubin content.

This research investigated the screen printing method for natural indigo dye on cotton fabric. We examined four types of thickening agents (arabic gum, guar gum, indalca, and CMC) based on their ability to retard the oxidation of natural indigo print paste while the paste remained on the screen frame. The results indicated that the retardation of arabic gum towards oxidation was the greatest among the four types of thickening agents. The highest K/S value of the printed cotton was observed with a dye concentration of 50g/L fermented indigo powder. The best printing results were obtained when the duration of dye efficiency was tested for the 10 minutes of the dye paste remaining on the screen with a thickening agent concentration of 26.56% that represented 530 cps viscosity. The test of colorfastness to washing and rubbing of the printed cotton resulted in grade 5, and the colorfastness to sunlight resulted in grade 4. Chinese traditional Naminwhapo printing was reproduced on cotton fabric using the natural indigo printing method derived from this study.

Efficacy of Flos Sophorae as UV protective dye was examined in comparison to standard dyes of quercetin and rutin. Cotton was dyed using Flos Sophorae extract, quercetin, and rutin with 2 different concentrations for each dye. Each type of dyeing applied a temperature of 70oC or 90oC and a time of 30 min or 60 min. Color values of dyed samples were examined using a spectrocolorimeter. HPLC-DAD analysis indicated the amount of quercetin and rutin contained in Flos Sophorae used in the study. UPF values of dyed samples were measured using an ultraviolet transmittance analyzer. Experimental results indicated that dyeing cotton with Flos Sophorae extract, quercetin, or rutin increased the UPF value and decreased the UVA and UVB transmittance (%) regardless of dyeing conditions. A higher rank of UPF values were shown in cotton dyed using the Flos Sophorae extract that implied the possible concerted effect of quercetin, rutin, and flavonoid compounds contained in Flos Sophorae. The results indicated that Flos Sophorae is an effective natural dye that can improve the UV protective function of summer cotton fabric.

This research investigated the dyeing behavior of palmatine (a major coloring compound of Phellodendron bark in addition to berberine) using mercerization (M), tannic acid (T), mercerization-tannic acid (MT), and tannic acid -mercerization (TM) pretreatments. Mercerization was conducted using 20℃ of 20% NaOH for 5 minutes. Tannic acid treatment was conducted using 15% o.w.f. solution of tannic acid at 60℃ for 30 minutes and fixed with potassium antimonyl tartrate trihydrate. Dyeing was conducted using 1% o.w.f. palmatine chloride hydrate with 1:100 liquor ratio at 10-95℃ for 10-60 minutes in a dyebath of pH 3-9. MT method resulted in the highest dye uptake and was two times higher than the average dye uptake of T method. MT method provided the best result when the dyeing temperature was 80℃ or 95℃ and the dyeing time was 60 minutes. The pH of the dyebath had less effect on the dye uptake but a pH higher than 5 provided better results. The study confirmed that palmatine is a major coloring compound of Phellodendron bark and that the MT method can be used as a successful cotton dyeing method.

This investigates the effect of hair toner formulated with Rubus Occidentalis L. extract on hair damaged by bleaching. The antioxidant functions of bokbunja material was examined via the tests of total phenol content, flavonoid content, and Vitamin B analysis. Bokbunja hair toner was prepared in 3 different concentrations. Untreated hair tress was bleached using a commercial hair bleaching agent and then treated with <shampoo→towel dry→air dry→toner treatment> once each day for 40 days. Hair samples were examined on their surface characteristics, tensile strength, and amount of protein leak. Total phenol content of the bokbunja material was 2999.50 μg GAE/mL and the flavonoid content was 955.140 μg CE/mL. Vitamin B contents were B2 0.403 μg/mL, B3 0.545 μg/mL, B5 0.357 μg/mL, B6 0.213 μg/mL, and B7 0.022 μg/mL. Tensile strengths of bleached hair without bokbunja hair toner treatment were 368.3 MPa, 386.2 MPa, and 479.4 MPa which were only 43.1~56.1% of the tensile strength of untreated hair. Bleached hair increased in tensile strength to 488.8 MPa, 549.2 MPa, and 521.6 MPa after 40 days of toner treatment. Bleached hair showed a higher amount of protein leak (218.48 μg/mL) compared to untreated hair (186.53 μg/mL). After 40 days of bokbunja hair toner treatment, the protein leak of hair treated with 3 different toners was 247.57 μg/mL (5%), 241.22 μg/mL (10%), and 267.13 μg/mL (15%) which were significantly higher than the protein leak of untreated hair as well as the protein leak of bleached hair without the toner treatment.

Chlorophyll is an abundant pigment found in all green plants, algae, and cyanobacteria. This study uses methanol, acetone and water to extract spinach and mate powders in order to examine the possibility of dyeing animal fibers with chlorophyll without chemical alteration. It was shown that methanol extracts of spinach and mate powders can be effectively used to dye wool and silk fabrics if the extract is mixed with water by methanol:water 65:35 v/v. Compared to methanol extract, the acetone extract showed lower chlorophyll yield and lower dye uptake. Water was not an appropriate solvent for chlorophyll extraction and dyeing. Spinach powder showed a higher dye uptake than mate powder due to the higher chlorophyll content than mate powder. It is possible that the chlorophyll dyeing of wool and silk fabrics is due to the hydrogen bonding between the hydroxy amino acids in fiber and the carbonyl groups of chlorophyll. These carbonyl groups are on the heterocyclic ring and the methyl and ethyl side chains of chlorophyll.

This research investigated the protective effect on hair for 3 commercial hair oil products containing UV filters upon UVA and UVB irradiation. Hair tresses each weighing 2 g were prepared from black virgin hair. Hair tresses treated with 0.5 g of hair oil were irradiated by UVA (365 nm) and UVB (302 nm) lamp for up to 600 hours. Color of hair was measured using a spectrocolorimeter, tensile strength and elongation of hair were measured using a biological tensile tester, surface morphology was examined using a scanning electron microscope. Experimental results were analyzed using SPSS statistical software. Hair color and tensile strength were both affected by UVA and UVB irradiation. Significant differences in the color and tensile strength were observed between untreated hair and hair treated with hair oils. Good UV protective effect observed in Oil 2 and Oil 3 was attributable to the type and the combination of UV filters contained in the products.
