Abstract

The invention provides a dye binder composition, and belongs to the technical field of textile dyeing and finishing. The composition includes repeating unit copolymers which are shown as a formula (1), (2) and (3). The copolymers of the composition include many strong polar active bonds, so that the copolymers are good in rheological property and can greatly enhance the cladding strength of a binder on dye molecules when being used for the dye binder, the abrasion fastness and water fastness of fabrics and/or clothing after dyeing can be significantly enhanced, and good soaping fastness, perspiration fastness and rubbing fastness can be achieved; and the fabrics are small in discoloration and soft in hand feeling.

Description

technical field [0001] The invention belongs to the technical field of textile dyeing and finishing, and in particular relates to a dye binder composition. Background technique [0002] Reactive dyes are widely used in the dyeing of cotton fabrics due to their bright color, complete varieties and chromatograms, low cost and easy use. Although reactive dyes can form covalent bonds with fibers, the stability of this bond is not very high, so some reactive dyes are not resistant to acid and alkali, oxidants, and heat treatment, resulting in discoloration , fading, staining and other phenomena. In addition, the color fastness of reactive dyes, such as chlorine fastness, washing fastness, perspiration fastness, and light fastness, is increasingly difficult to meet the current printing and dyeing requirements. Therefore, the use of fixatives and / or binders is a necessary option when printing with reactive dyes. [0003] At present, there are many types of reactive dye fixing ag...
