Sulfur dyes
| Глоссарий по текстилю и текстильной промышленности |
- A class of water-insoluble dyes that are applied in a soluble, reduced form from a sodium sulfide solution and are then reoxidized to the insoluble form on the fiber. sulfur dyes are mainly used on cotton for economical dark shades of moderate to good fastness to washing and light. they generally give very poor fastness to chlorine.

Vat dyes, английский
- A class of water-insoluble dyes which are applied to the fiber in a reduced, soluble form (leuco compound) and then reoxidized to the original insoluble form. vat dyes are among the most resistant dyes to both washing and sunlight. they are widely used on cotton, linen rayon, and other cellulosic fibers.

Disperse dyes, английский
- A class of slightly water-soluble dyes originally introduced for dyeing acetate and usually applied from fine aqueous suspensions. disperse dyes are widely used for dyeing most of the manufactured fibers. fiber-reactive dyes: a type of water-soluble anionic dye having affinity for cellulose fibers. in the presence of alkali, they react with hydroxyl groups in the cellulose and thus are liked with the fiber. fiber-reactive dyes are relatively new dyes and are used extensively on cellulosics when bright shades are desired.
