Problems solved by technology

Polyether can reduce the static friction coefficient (μS) between fibers and fibers, which is beneficial to stretching, but it increases the dynamic friction coefficient (μd) between fibers and metals, which is not conducive to stretching.

Abstract

The invention discloses a high-strength polyester POY oily agent. The high-strength polyester POY oily agent is prepared from, by mass, 40-60 parts of smoothing agent, 10-30 parts of emulsifier, 1-5 parts of antistatic agent, 20-40 parts of stabilizer and 10-20 parts of deionized water; the smoothing agent is prepared by compounding, by mass, 60-80 parts of polyether, 5-20 parts of mineral oil and0-10 parts of fatty alcohol ester or polyol ester; the emulsifier is a diphenylmethane dimeric surfactant, the antistatic agent is C8-C16 monoalkyl fatty alcohol polyoxyethylene ether phosphate, andthe stabilizer is tallowseed oil modified alkyd resin. The wear resistance and heat resistance of the oily agent are improved, the strength of an oil membrane is enhanced, friction coefficients of theoil membrane are increased, the fluctuation is small, and requirements for high speed spinning are met. The compatibility of polyether of the smoothing agent and the antistatic agent is improved, andthe strength of the oil membrane and the bundling performance of silk strips are improved. Emulsification is stable, good interfacial properties are achieved, the production process is environment-friendly and clean, and the high-strength polyester POY oily agent is suitable for certain-scale industrial production.

Description

technical field [0001] The invention relates to an oil agent, in particular to a high-strength polyester POY oil agent and a preparation method thereof. Background technique [0002] With the rapid development of my country's synthetic fiber industry, the output of polyester filaments has been increasing at a high speed in recent years, and the quality requirements are also constantly improving. In the fiber spinning process, the use of chemical fiber oil is essential, it can adjust the friction characteristics of the fiber, prevent or eliminate the accumulation of static electricity, endow the fiber with smooth and soft characteristics, and make the chemical fiber pass through spinning and stretching smoothly. , Textile spinning, weaving and other processes to ensure the production of high-quality high-strength fiber products. Since the oil agent on the surface of the fiber is first in contact with the production equipment, the configuration of the oil agent has a signific...
