Problems solved by technology

[0007] CN1284512A discloses a kind of synthetic method of alkyl polyether fatty acid ester (polyether ester), and its alkyl is butyl, octyl, lauryl etc., and fatty acid is monobasic acid, as lauric acid, palmitic acid, oleic acid, Stearic acid, etc., the polyether has good smoothness, cohesion, heat resistance and emulsification when used in spinning oils, and is suitable for civil silk oils or general industrial silk oils, but its drafting performance Poor, not suitable for use as a high-drawing ratio, high-performance industrial yarn spinning finish monomer
[0009] There are many patents on the synthesis and application of polyether, but most of them are applied to demulsifiers, polyurethane plastics, wetting agents, detergents, defoamers, dispersants and other additives, such as USP6316586, USP6458918, USP6683222, etc. The polyether introduced is not suitable for use in spinning oils, but the polyethers that can be used in spinning oils have poor smoothness under conditions of high temperature, high speed and high draw ratio

Description

technical field [0001] The invention belongs to acyclic saturated polycarboxylic acid ester, in particular to a fatty alcohol polyether dibasic acid ester and its synthesis and application. Background technique [0002] The rapid development of domestic synthetic fibers has brought about an increase in the amount of oil used, causing domestic and foreign oil agent development and manufacturers to work around the domestic chemical fiber oil market, especially the development of smoothing agents in chemical fiber oils is the focus of oil development. Because the main component of the oil agent is a smoothing agent, it has a great influence on the spinning performance and product quality, especially for industrial silk oil agents. [0003] The smoothing agents in spinning oils mainly include: ①Mineral oil, ②Animal and vegetable oil, ③Polyoxyethylene fatty acid ester, ④Fatty acid fatty alcohol ester, ⑤Polyoxyethylene fatty amine, ⑥Fatty acid polyol ester, ⑦Polyoxyethylene fatty ...
