Abstract

The invention provides a disperse dye dyeing defect preventing agent and a preparation method thereof. The disperse dye dyeing defect preventing agent is prepared from the following raw materials in parts by mass: 25-45 parts of disperse component, 10-30 parts of transfer dyeing component, 5-25 parts of an emulgator and 25-45 parts of a solvent. The disperse dye dyeing defect preventing agent is applicable to disperse dyeing of polyester and blended fabrics thereof under the conditions of high temperature and high pressure, and has the outstanding dispersion and transfer dyeing capabilities ondisperse dye, so that the dye can easily diffuse and evenly migrate from the dye liquor into the interior of fiber, and the problem of dyeing defect and color light shifting in the dyeing process canbe avoided.

Description

technical field [0001] The invention relates to an auxiliary agent used in the textile dyeing and finishing industry, in particular, an anti-stain agent, which can be specially used for high-temperature and high-pressure disperse dyeing of polyester. Background technique [0002] It is known that the crystallinity, orientation and glass transition temperature of polyester fibers are high, and due to the lack of active groups in the molecular structure that can combine with dyes like cellulose or protein fibers, the polyester molecules are arranged relatively tightly. , there are only small gaps in the fibers. Therefore, polyester has high requirements for dyeing conditions, usually at 130°C and pH value of 5-6, using disperse dyes for high temperature and high pressure dyeing. [0003] Disperse dyes are a kind of non-ionic dyes with low solubility in water and high dispersibility. When they are used, they are usually mixed with dispersants and suspended in water. Among the...
