After the corona pandemic, when consumers choose clothes, the issue of sustainability has become a more important selection criterion. The eco-friendly functional fiber used in the study is a smartcell, which has functions such as UV protection, decomposition of harmful substances, deodorization, antibacterial and biodegradation. This eco-friendly functional fiber was dyed using five kinds of natural dyes to examine the color change according to dyeability and dyeing conditions. As natural dyes, gardenia, turmeric, sappan wood, lac, and indigo were used. For comparison with smartcell, rayon, a cellulose regenerated fiber, and wool fiber, a protein fiber, were dyed under the same conditions to compare dyeability and color. The study results are as follows. It was found that smartcell had superior dyeability compared to rayon and wool in gardenia dye and showed lower dyeability than wool when dyeing turmeric, sappan wood, and lac dyes, but showed superior or similar dyeability than rayon. In case of indigo dyeing, the dyeability of smartcell was the best when dyed once, but it was found that smartcell had a lower effect on repeated dyeing compared to wool or rayon. Therefore, smartcell has superior dyeability compared to rayon fiber in gardenia, turmeric, sappan wood, and lac dyeing, and in case of indigo dyeing, it is suitable for light dyeing. When smartcell is produced as textile fashion products, natural dyeing is actively introduced and commercialized, and it is hoped that this study can be a reference material.

Greying of hairs or Canities (Sheeb) is a hair disorder characterized by premature graying of scalp hair, beard, moustache etc. In Unani system of medicine (USM), the causes of premature greying of hairs, concept behind graying of hairs, principles of treatment, preparations that prevent premature greying of hairs, regimen, systemic and local treatment to stimulate pigmentation and the most interesting point is the use of different type of hair dyes (khizabat) is all illustrated. Classical texts described black, red, blond and white hair dye preparations with formulae and method of use. Initially for the hair graying management, utilizing simple and complex substances from plants, minerals, metals and mixture of these was the main method, which satisfied the desire to change the colour of the hair. With the advancement in chemical science, dyes formulaes, method of formation and application are changed. But due to the awareness about demerits of chemical dyes, people are looking back towards the natural ways to combat hair greying and herbal hair dye is an alternative. This paper is an overview of Unani drugs of local and internal use for hair greying with special attention towards herbal dyes. Most commonly used herbs in khizaab with their actions and constituents has been summarized. This is an effort to globalize the benefits of Unani herbs in hair greying problem. In short, International demand for hair dyes has been steadily growing and there is a wide scope for exploring different aspects of hair greying treatment and dyes in USM.

It was the era, from 1876 to 1910, that some dramatic changes, including an influx of foreign dyes and the beginning of the modern dyeing manufacture, happened in Korea. This paper explores what dyes were sold in the market in this period, who was the main seller of the goods, and how the dyers produced their products. A wide range of natural dye stuffs coexisted with the various kinds of aniline dyes, alizarin dye and synthetic indigo in the market. Coloring materials had been sold by hwapi-jeon, a group of official merchants who acquired a privilege of monopoly from the government. However, the dyes were also traded by sang-jeon and yakguk merchants in the nineteenth century. Most of the synthetic dyes sold in Korea were produced in Germany or in Japan later, and imported in large amount by Chinese, Japanese and German merchants. Yet there also existed Korean merchants and peddlers who sold the goods to the local consumers. Dyers were male and female who belonged to the middle class. They received the orders and payments from the government or merchants. Not only did they dye textiles, threads, cotton, paper and leather, but they also redyed clothes. Indigo dyers were differentiated from other dyers. Modern dyeing manufacture, which was presumably forced to keep pace with the productivity of the weaving process, appeared in the 1900s. It was a branch of the modern weaving manufacture.

Objectives: This study evaluated the skin permeability of lawsone in henna hair dyes to understand the exposure characteristics of henna hair dyes in the human body. It examined the protective effects of protectants by applying protectants A, B, and C to test skin. Methods: Skin absorption tests were conducted using Franz diffusion cells according to OECD test guideline 428. After applying one kind of natural henna hair dye and chemical henna hair dye, respectively, to a standardized pig skin model, samples of receptor fluid were collected at 1h, 3h, 6h, and 24h. The skin permeation of lawsone was determined using HPLC. After the skin absorption experiment, the skin to which hair dye was applied was analyzed to determine the residual amount of lawsone in the skin. Results: The cumulative permeation of both natural and chemical henna hair dyes increased over time, and the natural henna hair dye had a flux value (t=3.194, p<.05) high both in the K_p value (t=3.207, p<.05) and the residual amount (t=22.701, p<.001). For skin treated with a protectant, the cumulative permeation of natural henna hair dye 24h control and the cumulative permeation of protectant A, B, and C increased over time. Flux and K_p values were in the order control > protectant A > protectant C > protectant B. The residual amount (F=4.469, p<.05) was in the order of protectant C > protectant A > protectant B > control. At 3h, the dye application time of natural henna hair dye, the lawsone flux value (F=4.454, p<.05) and K_p value (F=4.455, p<.05) were higher in the control group than in the protectant groups. The 24h cumulative permeation of the chemical henna hair dye increased with time in both the control and the protectant groups, and the flux and K_p values were in the order of protectant A > protectant C > protectant B > control. The residual amount (F=7.901, p<.01) was in the order of protectant B > protectant A> protectant C > control. Conclusions: Within the normal dyeing time for henna hair dye (three hours for natural henna hair dyes and 30 minutes for chemical henna hair dyes) lawsone skin penetration was not observed even when no protective agent was applied. After that time, however, evidence of skin penetration and retention of lawsone and the protective effect of protective agents were observed.

Recently. dyeing by harmless natural materials has received much attention due to the side-effects occurred from dyeing by synthetic dyes. In this study, we examined the effect of extracts of Pueraria thunbergiana (P. thunbergiana) roots, which are treated as natural products as well as agricultural wastes, on the hair dyeing by measuring dyeing interval, temperature, density changes, mordant and chromatic faction. The hair dyeing by the extracts significantly reduced hair damage and kept cuticle of hair softer than that by synthetic dyes. In addition, since a mordant is one of the necessary additives in dyeing, the role of a mordant was studied and concluded to be a supplementary substance based on the results that the hair dyeing by the extracts of P. thunbergiana roots alone was much darker than the others. Taken together, the data presented in this study suggest that the extracts of P. thunbergiana roots are is less damageable to hair and thus can be more safely applicable to hair dyes than that by synthetic dyes.

The wood veneers were clearly rainbow-colored with natural dyes. As shown through Korean-style jacket with stripes of multi-colors beyond traditional obang colors (red, blue, yellow, black and white colors), eco-friendly coloring methods representing Korean colors familiar from old times could be used nobly by coloring natural wood veneer being raw material of wood products. In terms of industrialization, the study to manifest korean color, substituting chemical stains such as dye and pigment, would be necessary. In order to realize this purpose, the study about economical dyeing materials and characteristics, that is, mordant, dyeing and drying techniques showing environment-friendly coloring and high coloration level ought to be followed. In addition to this, investigating discoloration transition by fading test for interior and exterior uses would have to be carried out.
