Abstract

The invention discloses a preparation method of a terylene low temperature dyeing carrier composition. The method comprises a step of mixing aromatic compounds with a weight fraction of 50 to 90, non-ionic surfactant with a weight fraction of 5 to 40, and an organic solvent with a weight fraction of 4 to 20; wherein the aromatic compounds are more than one of compounds (A), compounds (B), compounds (C), and diethylene glycol dibenzoate, the structures of compounds (A), (B), and (C) are represented in the description, R1 represents a C1-C4 alkyl group or benzyl group, R2 represents a C1-C4 alkyl group, R3 represents a hydrogen atom or a C1-C4 alkyl group, the nonionic surfactant is polyoxyethylene ether, and the organic solvent is an alcohol solvent and / or an alcohol-ether solvent. The preparation method has the advantages of simple operation, cleanness, and environment-friendliness. The prepared terylene low temperature dyeing carrier composition has the advantages of low cost, easy removal, high color fastness, low toxicity, and environment-friendliness.

Description

technical field [0001] The invention relates to a preparation method of a polyester low-temperature dyeing carrier composition. Background technique [0002] Polyester fiber is a hydrophobic fiber and lacks polar groups. Generally, three dyeing methods are used: high temperature and high pressure dyeing method, hot melt dyeing method and carrier dyeing method. [0003] The high temperature and high pressure dyeing method is suitable for pure polyester fabrics, with good dyeing depth and wide application range. However, for the dyeing of blended fibers such as polyester / wool, high temperature and high pressure dyeing will cause damage to wool, and it is necessary to lower the dyeing temperature to achieve satisfactory dyeing results. [0004] Carrier dyeing is to add carrier to the dye bath to plasticize the fiber and reduce the dyeing temperature, which is one of the commonly used dyeing methods. Early dyeing carriers, such as halogenated aromatic hydrocarbons, phenol deri...
