preparation example Construction

[0041] The preparation method of benzyl salicylate of the present invention is those well known to those skilled in the art. Specific preparation methods can be listed, for example: obtained by the reaction of salicylic acid and benzyl alcohol; obtained by the reaction of sodium salicylate and benzyl chloride, specific steps such as: in the mixture of sodium salicylate and slightly excess benzyl chloride Add a small amount of diethylamine, heat to 130-140°C, react for 17h, wash the reactant with water after cooling, remove excess benzyl chloride by steam distillation, vacuum distill the remaining oil, collect 170-175°C (0.93 kPa) fraction; derived from the esterification of salicylic acid and phenylethyl alcohol.

[0042] Based on 100 parts by weight of the nonionic surfactant, the benzyl salicylate is 1-10 parts.

Abstract

A high-performance environmental-friendly dyeing guide levelling agent composition comprises the following components of, by weight, 100 parts of non-ionic surface active agent and 1-10 parts of benzyl salicylate. The non-ionic surface active agent at least comprises fat alcohol ether, polyethylene glycol aliphatic ester and styryl phenol polyoxyethylene ether.

Description

technical field [0001] The invention relates to the field of textile printing and dyeing auxiliaries, in particular to a high-performance environment-friendly dyeing guide and leveling agent composition. Background technique [0002] Polyester is an important variety of synthetic fibers and is the trade name of polyester fibers in my country. It is a fiber-forming high polymer prepared from terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) through esterification or transesterification and polycondensation reactions—— Polyethylene terephthalate (PET), a fiber made by spinning and post-processing. [0003] From the perspective of polyester molecular composition, it is composed of short aliphatic hydrocarbon chains, ester groups, benzene rings, and terminal alcohol hydroxyl groups. In addition to the existence of two terminal alcohol hydroxyl groups in polyester seeds, there are no other polar groups, so the hydrophilicity of polyester fibers is...
