Disperse dyes
Глоссарий по текстилю и текстильной промышленности |
- 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.

Sulfur dyes, английский
- 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.

Basic dyes, английский
- A class of positive-ion-carrying dyes known for their brilliant hues. basic dyes are composed of large-molecule, water-soluble salts that have a direct affinity for wool and silk and can be applied to cotton with a mordant. the fastness of basic dyes on these fibers is very poor. basic dyes are also used on basic-dyeable acrylics, modacrylics, nylons, and polyesters, on which they exhibit reasonably good fastness.
