Natural dyes play an important role in sustainable dyeing processes. However, natural yellow with good performance are rare. Traditional have issues, such as a narrow color range and poor light fastness. In this paper, new dye was extracted from low-cost herb Geranium caespitosum L. (G. caespitosum). addition, the composition analyzed using UV-visible spectroscopy. The process of G. on wool fab...

Lately, the utilization of natural colorants in textile dyeing and printing has come to forepart manufacturing goods due increased environmental troubles. In this study, wool yarns were dyed with ternary dye combinations (Scutellaria Orientalis L, Rubia Tinctorium and, Punica Granatum L ). The color coordinates washing light fastness investigated. Washing are fair good. Dyed worked calorimetric...

This work presents the valorization of Millettia laurentii carpentry sawdust waste into sustainable natural dye for ecological dyeing and functional finishing wool textiles. A simple aqueous extraction method was used to isolate dye, then extracted bio-dye subjected different qualitative quantitative analyses. Wool yarns were dyed in conjunction with metal salts (aluminum sulfate, ferrous coppe...

Some reactive dyes (6a-6l) having Quinazolin-4(3H)-one system have been synthesized by coupling of diazotized 3-(4-(5-(4-aminophenyl)-1,3,4-oxadiazol-2-yl) phenyl)-4-oxo-2-phenyl-3,4-dihydroquinazoline-6-sulphonic acid with cyanurated components such as H-acid, J-acid, N-methyl Gamma acid, Peri Sulpho Tobias Koch Bronners Chicago K-acid, N-Phenyl J-acid and M-acid. The were characterized nitrog...

Hand dyeing generates artistic representations with unique and complex patterns. The aesthetics of dyed patterns on a cloth originate from the physical properties of dyeing in the cloth and the geometric operations of the cloth. Although many artistic representations have been studied in the field of nonphotorealistic rendering, dyeing remains a challenging and attractive topic. In this paper, ...
