Abstract

The invention provides a polyamine formaldehyde-free fixing agent as well as preparation and application method thereof. The polyamine aldehyde-free fixing agent is prepared from the following components in parts by weight: 8 to 15 parts of organic amine monomer, 5 to 15 parts of N-aminoethyl piperazine, 10 to 20 parts of quaternary ammonium cationizing agent, 15 to 25 parts of dicyandiamide, 2 to5 parts of organic acid, 8 to 15 parts of organic solvent, 5 to 15 parts of epichlorohydrin, 10 to 20 parts of cationic etherifying agent, 5 to 10 parts of polyvinyl alcohol (PVA) and 40 to 60 partsof deionized water. The polyamine formaldehyde-free fixing agent provided by the invention is green and environmentally friendly, and can eliminate reddish color produced during dyeing while fixing, thus avoiding repairing dyeing, and effectively improving various color fastnesses of fabrics, such as washing fastness, friction fastness and boiling water fastness.

Description

technical field [0001] The invention relates to an auxiliary agent used in the textile dyeing and finishing industry, in particular, a color-fixing agent used for color-fixing treatment of fabrics dyed with reactive dyes and a preparation and use method thereof. Background technique [0002] It is known that the color fastness of textiles in the printing and dyeing industry (abbreviated as color fastness) refers to dyed or printed fabrics in the process of taking or processing, after the dyes on the fabric are subjected to various factors, such as extrusion , friction, washing, rain, exposure, light, seawater immersion, saliva immersion, water stains, sweat stains, etc., and can maintain its original color performance. [0003] Among them, reactive dyes are popular in the printing and dyeing industry because of their bright color, complete chromatogram, economical process, simple operation, good level dyeing, and low price. Among the pure cotton printing and dyeing products...
