The dyes used for dyeing cotton fabrics mainly include direct dyes, reactive dyes, vat dyes, soluble vat dyes, insoluble azo dyes, sulphur dyes, etc.

Cangzhou Xincheng Weiye Chemical textile cotton dyes mainly include direct dyes and sulphur dyes. Here we’d like make a simple introduction for the cotton fabric dyes.

Direct dyes are soluble in water and can be directly dyed on cotton fibers in neutral or weak alkaline solutions. Adding neutral electrolytes such as salt during dyeing can increase the amount of impurities on the dye. The direct dye chromatogram is complete, the dyeing method is simple, and the price is relatively cheap.

Our direct colors have direct pink red 12B, direct sky blue 5B, direct black VSF, direct yellow R, direct congo red etc.

Sulphur dyes are insoluble in water, but can be dissolved in sodium sulfide solution and reduced to leuco body. After the leuco body is absorbed by cotton fiber, it is oxidized to insoluble dye and fixed on the cotton fiber. Sulphur dyes are mainly used for dyeing cotton fiber dark products.

The washing and sun exposure are good, the dyeing method is simple and the price is cheap.Our sulphur colors include sulphur yellow GC, sulphur blue CV, sulphur black dyes, sulphur green 14 etc.
