Problems solved by technology

[0004] At present, the common problems of polyester POY high-speed spinning oils are: the viscosity-temperature-viscosity characteristics of many polyether monomers are not ideal. Low viscosity, the oil on the fiber will splash on the hot roller under the action of centrifugal force. Long-term heating will easily lead to the formation of coke, which will affect the heat conduction efficienc

Abstract

The invention provides a preparation method of a high-speed polyester POY (Pre-Oriented Yarn) spinning oil agent. A pure oil agent except for water in the oil agent is composed of a main body part and an additive, wherein the main body part includes over 20 kinds of polyether compounds and the rest components belong to non-polyether additive. The preparation method comprises the following steps: firstly, metering the main body component of the oil agent, pumping the main body component into a reaction kettle in vacuum, stirring, heating to 50-70 DEG C, stirring, metering the additive components and water, and adding the metered additive components and water into the reaction kettle, stirring, heating to 70-80 DEG C, keeping the temperature for 40-50min, closely filter-pressing a product, and subpackaging the product after the product is checked to be qualified. The oil agent prepared by using the method provided by the invention is suitable for high-speed polyester POY spinning and a production process of a subsequent deform yarn; the oil agent endows the fiber good smoothness and bundling and favorable total viscosity-temperature and viscosity-concentration characteristics; the fiber is few in broken filament breaks, even and uniform in dyeing in the later drafting process; the smoke formation amount of a hot processing tank is small, generated white powder and coke amount are small and the cleaning period is long; a product is good in quality and stability.

Description

technical field [0001] The invention relates to an oil agent used in the spinning process of synthetic fibers, in particular to a preparation method of a polyester POY high-speed spinning oil agent. 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, pre-oriented yarn or partially oriented yarn (POY, Pre-Oriented Yarn or Partially Oriented Yarn) and stretched textured yarn (DTY, Draw Texturing Yarn). Step combination, 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 3000~4600 m / 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 ...
