Abstract

The invention relates to a preparation method of polyester spinning oil and belongs to the technical field of textile auxiliaries. The preparation method comprises mixing white oil and pentaerythritol oleate to obtain mixed oil, mixing Arabic gum and deionized water, heating the mixture, adding maltodextrin into the mixture, carrying out stirring, adding the mixed oil into the mixture, carrying out emulsification and homogenization to obtain high temperature-resistant capisulazed mixed oil, mixing the high temperature-resistant capisulazed mixed oil, polyoxyethylene sorbitan monolaurate and lauroyl diethanolamine to obtain a composite emulsifier, mixing the composite emulsifier and the high temperature-resistant capisulazed mixed oil, carrying out ultrasonic emulsification to obtain an emulsion and mixing the emulsion and sodium benzoate. The polyester spinning oil has good heat resistance and a smoking temperature of 220 to 240 DEG C, improves the smoothness of the oil film, reduces fiber filament and breaking possibility, and can be widely used in the polyester spinning field.

Description

technical field

[0001] The invention relates to a preparation method of polyester spinning oil, belonging to the technical field of textile auxiliaries. Background technique

[0002] In my country, the trade name of PET polyester (polyethylene terephthalate) silk fabrics is called polyester. Polyester spinning generally adopts high-speed spinning-drawing and twisting process in China, that is, the two-step combination of pre-oriented yarn or partially oriented yarn and stretched textured yarn, referred to as POY-DTY process. In order to make polyester POY have a higher degree of orientation and crystallinity, the spinning speed is usually in the range of 3000-4600m / min. The faster the spinning speed, the higher the production efficiency. Polyester POY high-speed spinning requires that the spinning oil used should have good smoothness, bunching and antistatic properties, so as to ensure good tow formation, proper hugging and less broken ends of wool. In addition, the subseq...
