Abstract

The purpose of the present invention is to provide a preparation method of polyester spinning oil, firstly prepare the aqueous solution of diamine hydrogen phosphate and calcium nitrate, then add cellulose nanocrystals, polylactic acid and polyglycolic acid to react at a certain temperature After a period of time, emulsion A is obtained; polyoxyethylene coconut oleate, sorbitan stearate, C 5-10 Saturated fatty alcohol oxyethylene ether and tung oil are mixed and reacted to prepare emulsion B; after mixing emulsion A and emulsion B evenly, an oil agent for polyester spinning is obtained. The polyester spinning oil prepared by the invention has good wetting and permeability, low surface tension, small usage, and low production cost, and can endow polyester fibers with good smoothness and bunching properties, and the fibers will be smooth and bundled in the subsequent drawing process. Less wire breakage, good product stability.

Description

Technical field: [0001] The invention relates to the field of textile auxiliaries, in particular to a preparation method of an oil agent for polyester spinning. Background technique: [0002] Polyester is the largest and most widely used synthetic fiber variety in the world. At present, polyester accounts for more than 100% of the world's synthetic fiber output, and the output of filament yarn accounts for 71% of polyester output. Among them, the output of FDY filament accounts for about 30% of polyester filament output. Polyester is an important variety of synthetic fibers and is the trade name of polyester fibers in my country. It uses purified terephthalic acid or dimethyl terephthalate and ethylene glycol as raw materials, undergoes acidification or transesterification, and then polycondenses to obtain a fiber-forming high polymer, polyethylene terephthalate. , which can be produced by spinning and post-processing. The so-called polyester filament is a filament made of...
