Description
Technical Field
The invention belongs to the technical field of preparation of polyester oiling agents, and particularly relates to a polyester FDY oiling agent and a preparation method thereof.
Background
Polyester, commonly known as polyethylene terephthalate (Polyethylene Terephthalate, PET for short), is a lightweight synthetic fiber, belonging to polyester fibers. The terylene has the characteristics of high strength, good elasticity, crease resistance, abrasion resistance, chemical corrosion resistance, low hygroscopicity, good heat resistance and the like, and is widely applied to textile industry, including clothing, bedding articles, curtains, home textiles and the like. In addition, polyester is also commonly used for producing ropes, industrial filter materials, automotive interiors, packaging materials, and the like, due to its excellent physical properties. Particularly important, the terylene is a recyclable material, and the requirement for new raw materials can be reduced by recycling the terylene, thereby being beneficial to environmental protection.
The fully drawn polyester yarn (FDY) is one of the main products of the polyester industry in China, and the preparation method is mainly a spinning and drawing one-step method combining high-speed spinning (with the spinning speed of 2600-350 m/min) and ultra-high-speed drawing and winding (with the winding speed of 5100-5500 m/min), and compared with the traditional process of combining low-speed spinning with high-speed drawing and winding, the method has the advantages of low cost, stable product quality and the like. However, since synthetic fibers do not have natural gum and oil film which natural fibers have, they are poor in hygroscopicity and nonconductive, static electricity is easily generated by continuous friction during spinning, and it is necessary to use an auxiliary agent to prevent or eliminate static electricity accumulation, and at the same time, to impart soft and smooth properties to the fibers so that the fibers pass through the subsequent processes smoothly, and such an auxiliary agent is collectively called a fiber spinning oil.
The polyester is the synthetic fiber variety with the largest productivity and the widest application in the world, and in the chemical fiber industrial yield of China, the polyester yield accounts for more than 80 percent of the total yield, but the quality and performance requirements on the oiling agent are extremely high due to the high speed and large friction of the FDY spinning process of the polyester high-speed spinning, so that the independent industrial preparation technology of the FDY oiling agent for the high-performance polyester high-speed spinning of China is mainly dependent on import at present. At present, the technical difficulty of the FDY oiling agent for high-performance polyester high-speed spinning in China is mainly as follows:
In the high-speed spinning process, the oiling agent needs to be capable of flowing fast and uniformly coated on the surface of the fiber, so that the terylene FDY oiling agent is required to have good ductility and flowing capability, such as proper viscosity, good fluidity, good adhesion capability and the like, and compared with pure oiling agent, the emulsion oiling agent has better ductility and lower cost and is more suitable for lubrication in the high-speed spinning process. However, since the moisture in the emulsion type oil is easily volatilized by hot roll drawing and extrusion and high temperature heating, the oil film on the surface of the fiber is easily broken, thereby changing the friction characteristics of the fiber, increasing the friction force of the fiber, leading to hairline and broken ends, and the like, the oil is required to have high oil film strength. However, the low oil film strength is a main characteristic and defect of the emulsion type oiling agent, and how to improve the oil film strength of the emulsion type oiling agent, so that the emulsion type oiling agent can be used as an FDY oiling agent in a polyester high-speed spinning process, and is one of technical problems to be solved urgently by those skilled in the art.
In addition, because the FDY spinning process of the polyester high-speed spinning is high in speed and high in friction, the temperature of the polyester filaments can be up to about 200 ℃ in the stretching deformation process, so that the FDY oiling agent is required to have good high temperature resistance and oxidation resistance so as to improve smoking and coking phenomena.
