Abstract

The invention provides a crosslinking type formaldehyde-free color-fixing agent emulsion and a preparation method thereof. The formaldehyde-free color-fixing agent emulsion comprises a dimethyl diallyl ammonium chloride monomer, a diallylamine hydrochloride monomer, a chelating agent, an organic alkane solvent, an emulsion stabilizing agent, an emulsifying agent, an oil-soluble thermal initiator, an active activating agent and the like, and is prepared by an inverse emulsion polymerization process; in the preparation process, the monomers are dispersed into fine bead granules by adding the organic alkane solvent and through emulsification to perform polymerization, and polymerization heat is transmitted continuously through the organic solvent, so that temperature increment is mild and gentle and is easy to control in the reaction process, the molecular weight of the product is remarkably increased by compared with that of solution body polymerization, and the color of the product is light by compared with that of solution body polymerization. The viscosity of the product after inverse emulsion polymerization is low and does not exceed 1000 cp generally, so that motor load is small and power consumption is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of textile auxiliaries, in particular to a cross-linking formaldehyde-free color-fixing agent, in particular to a cross-linked color-fixing agent of a copolymer of dimethyl diallyl ammonium chloride and diallylamine hydrochloride Emulsion and method for its preparation. Background technique [0002] Fixing agent is an auxiliary agent used to improve the color fastness of dyes on fabrics to wet treatment, and is one of the indispensable and important auxiliary agents in the printing and dyeing industry. For a long time, people have been using dicyandiamide and formaldehyde condensation resin color fixing agent for textile color fixing treatment. With the continuous enhancement of environmental protection awareness, dyeing auxiliaries continue to develop in the direction of green environmental protection, high efficiency and energy saving, no or low aldehyde The color fixing agent has become the main directio...
