Abstract

The invention discloses a reactive dye colorfastness-to-bleeding improving agent, as well as a preparation method and application thereof. The reactive dye colorfastness-to-bleeding improving agent isprepared from the components: 50 to 70 parts of component A, and 30 to 50 parts of component B, wherein the component A comprises 10 to 30 parts of acrylamide, 5 to 10 parts of urea, 10 to 30 parts of methacrylic acid, 5 to 15 parts of stearic acid, 10 to 40 parts of polyethylene polyamine, 10 to 30 parts of distilled water, 5 to 15 parts of ammonium chloride, and 0.5 to 2 parts of initiator; thecomponent B comprises 5 to 10 parts of non-ionic surface active agent, 20 to 30 parts of quaternary ammonium salt, 40 to 80 parts of distilled water, and 1 to 5 parts of acidifier. The invention further provides the preparation method and the application of the reactive dye colorfastness-to-bleeding improving agent. According to the reactive dye colorfastness-to-bleeding improving agent, as wellas the preparation method and the application thereof provided by the invention, a dye is firmly fixed to the surface of a fabric, the adverse effect of metal ions on colorfastness to bleeding is effectively avoided, the surface tension of water is greatly reduced, the reactive dye is uniformly distributed on the fabric, a dyeing effect is good, the use performance is excellent, and the cost performance is high.

Description

technical field [0001] The invention belongs to the technical field of textile auxiliaries, in particular to an agent for improving the color fastness of reactive dyes and its preparation method and application. Background technique [0002] Reactive dyes are a type of reactive dyes that are widely welcomed by printing and dyeing enterprises. At present, reactive dyes have replaced most direct dyes, sulfur dyes and some vat dyes, becoming the most important cotton dyes. With the continuous upgrading of people's consumption level, consumers have put forward more and more requirements for reactive dye dyeing. Reactive dyes have many advantages, such as: bright color, complete chromatogram, economical process, simple operation, good level dyeing, and low price. These advantages of reactive dyes are accelerating the large-scale application of reactive dyes. [0003] With the rapid development of textile production technology, the quality requirements of textile products are ge...
