Abstract

The invention discloses an amphiphilic polyamine high-molecular polymerization type viscose cotton blending leveling agent and a preparation method thereof. The amphiphilic polyamine high-molecular polymerization type viscose cotton blending leveling agent is prepared from the following components: a copolymer of acryloylethylenediamine and acryloylethylenediamine succinic acid, a polycondensate of the acryloylethylenediamine succinic acid and ethylenediamine, a solvent and deionized water. According to the amphiphilic polyamine high-molecular polymerization type viscose cotton blending leveling agent and the preparation method thereof, a series of amphiphilic ionic polymers and polyamide compounds are synthesized, no waste gas is generated in the synthesis process, and the purpose of level dyeing is achieved through solubilizing and retarding dyeing of the dye; and meanwhile, the leveling agent is almost non-irritant to organisms and is easy to biodegrade.

Description

technical field [0001] The invention relates to the technical field of fabric treatment, in particular to an amphoteric polyamine polymer polymerized viscose cotton blended leveling agent and a preparation method thereof. Background technique [0002] Viscose belongs to regenerated cellulose fiber, which is chemically modified from natural fiber. It has multiple advantages of chemical fiber and cellulose fiber. The high-quality, soft and smooth fabric feels better in wearing fabrics, but viscose The heat and alkali resistance and friction resistance of the fiber are poor, so the blended fiber of viscose has grown rapidly in recent years, especially the blended fiber of viscose and cotton. [0003] Viscose cotton blended fibers are usually dyed with reactive dyes in one bath, but the dyeing properties of these two fibers are quite different. The dyeing of reactive dyes usually goes through three steps of diffusion, adsorption and fixation to dye the amorphous area of ​​cellu...
