Problems solved by technology

[0004] With the continuous development of polyester textile technology, higher standards have been put forward for polyester spinning oils. When traditional polyester spinning oils are spun at high temperature and high speed, the spinning oils on polyester fibers will volatilize and decompose. If it falls off, the strength of the oil film will be reduced and the smoothness will be deteriorated. At the same time, there will be coking on the hot yarn. Not only that, a polyester is formed by stretching and deforming many monofilaments. The oil of the traditional spinning oil Insufficient wettability, unable to quickly and evenly adhere to the fiber surface, poor cohesion between fibers, and low fiber strength

Abstract

The invention discloses polyester spinning oil. The polyester spinning oil is prepared from higher fatty acid triethanolamine salt, lauroyl diethanolamine, pentaerythritol oleate, a smoothing agent, an antistatic agent, a preservative, an emulsifying agent, an anti-splashing agent, and a permeating agent. According to the polyester spinning oil and the preparation method thereof, the bundling performance of the oil can be improved very well by taking the higher fatty acid triethanolamine salt as a bundling agent; the pentaerythritol oleate and the lauroyl diethanolamine have good heat resistance and viscosity properties, and can improve the wettability and temperature resistance of the oil very well; the anti-splashing agent is added, so that the viscosity of the oil is improved, and meanwhile, the tension surface of the oil is greatly increased; therefore, the attachment degree of the oil is high; the permeating effect of the oil is good through the permeating agent; and more oil permeates into yarns.

Description

technical field [0001] The invention belongs to the technical field of polyester spinning oil, and in particular relates to a polyester spinning oil and a preparation method thereof. Background technique [0002] In the production and processing of polyester, oil agent is an extremely important auxiliary agent, especially when spinning POY and DTY polyester filaments, it is an indispensable and important textile auxiliary agent in the spinning process. Because polyester fiber does not have the natural colloid and softness of natural fibers, and has poor hygroscopicity and non-conductivity. In the spinning process, unlike natural fibers, natural colloid can play the role of antistatic, clustering and moisture absorption. The effect is to make the fiber have good smoothness. Spinning oil is an important reagent for fiber post-processing. It can increase the cohesion between polyester fibers during processing, reduce the friction coefficient between fibers and machinery, reduc...
