Technical Field

The invention belongs to the technical field of polyester spinning oil agents, and particularly relates to a polyester spinning oil agent and a preparation method thereof.

Background

In polyester production and processing, the oil agent is an extremely important auxiliary agent, and is an essential important textile auxiliary agent in the spinning process particularly when POY and DTY polyester filaments are spun. Because the polyester fiber does not have the natural colloid and softness of the natural fiber, has poor hygroscopicity and no conductivity, the natural colloid can play the roles of static resistance, bundling and moisture absorption unlike the natural fiber in the spinning process, so that the fiber has good smoothness. The spinning oil agent is an important reagent for fiber post-processing, can increase the holding force of the polyester fiber in the processing process, reduce the friction coefficient between the fiber and machinery, reduce the generation of static electricity, and achieve the same easy processing property as natural fiber.

The development and production of chemical fiber oil in China begin in the early 90 s of the 20 th century. Although starting late, the development is rapid. The research and production units of the oil agent develop from the first research institute of synthetic fibers in Shanghai and the Tianjin lightening institute of a few units to hundreds of research units and production enterprises of Zhejiang heritage, Jiangsu Tianyin chemical industry, Zhejiang Huangma chemical industry, Zhejiang Hengyuan chemical industry and the like. At present, chemical fiber oil agents mainly comprise DTY oil agents, FDY oil agents, POY oil agents and short fiber oil agents, and the chemical fiber oil agents are complete. The typical components of the conventional chemical fiber oiling agent are spinning oiling agent consisting of smoothing agent (55-65%), emulsifying agent (17-27%), bundling agent (5-15%), antistatic agent (2-8%) and other additives (1-5%), which can meet the conventional spinning process requirements of terylene and effectively improve the spinning quality of terylene.

Along with the continuous development of polyester spinning technology, a higher standard is provided for polyester spinning oil, when the traditional polyester spinning oil is used for high-temperature and high-speed spinning, the spinning oil on polyester fibers can be partially volatilized and decomposed, the oil film strength is reduced, the smoothness is poor, the coking phenomenon can occur at a heat station at the same time, and moreover, one polyester fiber is formed by stretching and deforming a plurality of monofilaments.
