This document discusses reactive dyes and disperse dyes used for dyeing textiles. It provides details on: - Reactive dyes chemically bind to cellulose fibers and provide excellent wet fastness. Disperse dyes are used for synthetic fibers like polyester and acetate. - Dyeing conditions like temperature, time and pH levels vary depending on the type of dye and fiber. Proper dye selection and process is needed to achieve good color fastness. - Blends require multi-step dyeing using both reactive and disperse dyes in separate baths or a single bath approach to dye both natural and synthetic fiber components.
