Abstract

The invention belongs to the technical field of fine chemicals, and particularly relates to a preparation method of an environment-friendly high-temperature leveling agent for fabric. Arginine and ethylene oxide are polymerized to prepare leveling agent mother liquor for the first time, and then a final product, the environment-friendly high-temperature leveling agent for the fabric, is prepared from the leveling agent mother liquor, urea and sulfamic acid through a one-pot method. Raw materials are green and environmentally friendly, production conditions are simpler and more convenient, and production is facilitated. The prepared environment-friendly high-temperature leveling agent for the fabric is green and environmentally friendly, and is excellent in transfer dyeing performance (the transfer dyeing rate is as high as 42.6%).

Description

technical field [0001] The invention belongs to the technical field of fine chemicals, and more specifically relates to a preparation method of an environment-friendly high-temperature leveling agent for fabrics. Background technique [0002] High-temperature leveling agent is mainly a dyeing auxiliary for polyester fabrics. The basic component of polyester is polyethylene terephthalate. From the molecular structure of polyester, it lacks active groups that can combine with dyes. Therefore It cannot be dyed directly with acid dyes, reactive dyes, etc., only water-insoluble disperse dyes can be used for dyeing. And because the polyester molecules are arranged relatively closely, there are only small gaps in the fiber, and it is difficult for the dye molecules to enter the interior of the fiber under low temperature conditions. The gaps allow the dye molecules to enter the interior of the fiber. Therefore, the dyeing of polyester fibers is carried out under high temperature ...
