This rolled fabric is then loaded into a vessel which is then closed and pressurized. The dye is then permitted to circulate by means of the holes in the beam by way of which it dyes the fabric. However, the reported researches about the azo-anthraquinone dyes mainly focused on acid and disperse dyes, but rarely on reactive dyes. In contrast, reactive dyes are extensively utilised in the textile industry because they can be linked onto the fibers by means of covalent bonds, and the dyed fibers have higher fastness to wet treatment . This process is accomplished to dye the fabrics of longer length.
Orcinol following oxidation forms purple orceins or litmus. The colour of each litmus and orchil depend on the pH of the solution . In acidic pH dyestuff forms red cation, and in simple pH, it types bluish violet anion.
Dyeing of polyester with disperse dyes have very good light fastness. This does not usually correlate with the light fastness on other fibres such as cellulose diacetate. Disperse dyestuff sector is most important and a significant categories, does not include powerful water-soluble group, a dispersed state class of nonionic dyeing dyes in the dyeing procedure. After production of the original dye, the subject therapy method, comprising a steady crystal type, such as grinding and dispersing agent together commercialization, in order to obtain the dye solution. Primarily made use of for dyeing polyester and blended fabrics. Synthetic fibers can also be used dyeing cellulose acetate, nylon, polypropylene, polyvinyl chloride, acrylic and the like.
A sample dye cloth produced with dye extracted from Polygonum pensylvanicum, commonly known as Smartweed. 20 grams of calcium carbonate added to 2 liters of warm water. For 235 grams of fiber at eight% WOF, I made use of 18 grams of Gallo tannin in a massive pot of hot tap water.

The catechinone dyes hair orange, reddish orange or deep yellowish brown depending on dyeing situations such as the oxidation approach, dye concentration, temperature, pH and additives . The colour fastness of the hair dyed by catechinone to washing and light is higher enough as similar as that of oxidation hair dyes . Nonetheless, the dyeability of catechinone is not high enough for sensible use, due to the fact the hair dyeing by working with it is mild way and the dye colourant molecules do not vigorously penetrate into hair. As a result, enhancing its dyeability without having utilizing harmful agents is critical and requisite for creating the technique. The quality of the sukumo determines the vividness of the color.
