Background
Polyester fibers, commonly known as "dacron". The PET fiber is a synthetic fiber obtained by spinning polyester formed by polycondensation of organic dibasic acid and dihydric alcohol, is called PET fiber for short, and belongs to a high molecular compound. Invented in 1941, is the first major variety of current synthetic fibers. The polyester fiber has the advantages of good crease resistance and shape retention, high strength and elastic recovery capability. It is firm and durable, has the functions of resisting wrinkle, preventing ironing and preventing hair from sticking. Polyester fibers (dacron) are widely used in clothing, home furnishings and other industrial fields. However, macromolecules of the polyester fiber are mutually connected through covalent bonds, cannot be ionized, cannot transmit electrons and ions, and has small molecular group polarity, so that the polyester fiber belongs to hydrophobic fibers, static electricity is easily generated, the static electricity not only causes difficulty in the production process of the polyester fiber, but also makes fabrics intertwine and absorb dust, and clothes entangle human bodies to generate uncomfortable feeling, and in addition, the static electricity is one of main induction reasons causing accidents such as fire, explosion and the like, so that the application of the polyester fiber is limited. Therefore, in order to expand the application of the polyester fiber, the antistatic modification of the polyester fiber is very important.
At present, there are many modification methods for antistatic polyester fiber at home and abroad, and the modification method can be roughly divided into 3 types according to modification implementation stages, namely, modification in a polymerization stage; secondly, modification in the spinning stage; thirdly, finishing the fiber or the fabric; the third method has low production cost and easy implementation, and is widely used in China, in the prior art, a surface active agent is usually used as a finishing agent to impregnate the woven fabric, and the hydrophilicity of the surface active agent is used for improving the conductivity, but the antistatic performance of the finishing agent is more general.
Therefore, an antistatic finishing method for durable polyester fabrics is provided to solve the problems.

Result detection
1. Hydrophilicity test method: the woven fabrics of examples 1 to 5 were placed in a thermostat, the temperature of the thermostat was maintained at 20 ℃ and the humidity was maintained at 35 ℃, and then 5 sample woven fabrics were taken out and tested for electrostatic half-life on an electrostatic instrument, respectively, with the control being an unfinished woven fabric. Specific detection results are shown in table 1.
TABLE 1 Electrostatic half-Life
| Group of | Electrostatic half life period/s |
