Description
Technical Field
The invention relates to a polyester fiber Fully Drawn Yarn (FDY) oiling agent, belonging to the technical field of chemical fiber spinning oil.
Background
The spinning process of the polyester Fully Drawn Yarn (FDY) greatly improves the spinning production efficiency due to the high spinning speed (4200 m-5500 m/min), and occupies an increasingly large proportion in the existing polyester spinning process. However, since the polyester fiber is a hydrophobic polymer compound, in the full-drawn polyester spinning process, friction between fiber tows and between the fiber and metal equipment can generate a large amount of static electricity, which causes problems of fiber breakage, loosening and the like, and in severe cases, fiber production cannot be performed at all, thereby bringing serious economic loss to chemical fiber manufacturers. In order to ensure the smooth production of the polyester fiber, the oiling of the fiber tows becomes the necessary condition for ensuring the normal production. The spinning oil agent has the function of enabling the performances of the friction property, the antistatic property, the cohesion property and the like of the polyester fiber to be in a proper range in the spinning process so as to ensure the normal production of the fiber.
Because the hydrophilicity of the polyester fiber is poor, the critical surface tension of the polyester is 43dyn/cm, and the spinning speed of the polyester FDY is generally 4200 m/min-5500 m/min, the high spinning speed, the poor hydrophilicity and the low surface tension of the polyester fiber are added, and the oiling process is finished instantly, so that the uniform oiling of the fiber is difficult to achieve. In addition, in the high-speed spinning process, the setting temperature of the second hot roller is as high as 130-150 ℃, so that the oiling agent is required to have good thermal decomposition resistance in addition to excellent performances such as smoothness, antistatic property and the like, and if the heat resistance of the oiling agent is poor, the oiling agent on the fiber is contacted with high temperature during stretching and setting, and is decomposed into precipitates such as oil stains, oil residues and the like, and the precipitates are attached to the setting hot roller, so that the friction force is increased, and the production problems such as broken ends of fiber filaments and the like are caused. In addition, the smoke generated by the pyrolysis of the oil agent greatly deteriorates the working environment of a production workshop and seriously damages the health of production personnel, so that the terylene FDY oil agent has excellent thermal decomposition resistance. In the prior art, mineral oil, fatty acid ester, polyether, fatty alcohol-polyoxyethylene ether phosphate and other monomers are mostly adopted to compound an oil agent, and the monomer is used for compounding the oil agent, so that the performances of smoothness, cohesion, antistatic property and the like of the oil agent can meet the requirements, but the fatty alcohol-polyoxyethylene ether phosphate is not high-temperature resistant and is easy to decompose and coke on a shaping hot roller due to heating, so that the friction force is increased, and the fiber breakage and other problems are caused. The invention discloses a terylene high-speed spinning oil agent and a manufacturing method thereof in China patent CN99124724, a terylene FDY spinning oil agent and a manufacturing method thereof in CN101629383, an FDY oiling agent and a manufacturing method thereof in CN101392458, and an FDY oiling agent and a manufacturing method thereof in CN 101392458B.
The existing literature reports that silicon element has better heat resistance, and is nontoxic, cheap and easily available. However, reports and products for improving the heat resistance of the oil by adding organic silicon phosphate serving as an antistatic agent into a polyester spinning oil are not found at present.
