2. With the rapid and sharp increase of the output of synthetic fibers, the problem of spinning static electricity is increasingly acute, and the most widely used at present is a surfactant type antistatic agent which can dissipate static electricity by migrating to the surface of polymer fibers and adsorbing water in the surrounding environment to form a conductive water film so as to fulfill the aim of resisting static electricity. The surfactant type antistatic agent has main disadvantages in that antistatic durability is poor, scrubbing is not resisted, dependence on environmental humidity is large, heat-resistant temperature and surface characteristics of a fiber material are reduced, and the fiber material is in a negative influence on human bodies after being separated from polymer fibers. Therefore, it is important to prepare an antistatic agent which is resistant to migration, has low toxicity and does not reduce the performance of the fiber material.

3. Polypropylene has the advantages of high strength, good elasticity, wear resistance and corrosion resistance, but the hygroscopicity is too poor, so that static electricity is easily generated, and in addition, the heat resistance and the aging resistance of polypropylene are poor. According to the invention, polyacrylamide with good hygroscopicity is added into polypropylene, and the modified polypropylene grafted and blended with the polyacrylamide is prepared by adopting a liquid phase blending method, so that the binding capacity of the polypropylene to water molecules is improved, the activity of functional groups on the surface of the polypropylene is also improved, and the modified polypropylene has better compatibility and binding property with other components in the antistatic fiber.

According to the invention, calcium dobesilate is used for modifying polyphenylene sulfone resin, dobesilate groups are grafted in molecules of polyphenylene sulfone, the dobesilate groups are surface active groups, and a long carbon chain hydrophobic group contained at one end of the dobesilate groups can be combined with polyphenylene sulfone molecules, so that a hydrophilic group at the other end is exposed on the surface of the polyphenylene sulfone, and the calcium dobesilate modified polyphenylene sulfone resin not only can improve the surface activity of the polyphenylene sulfone, but also greatly enhances the antistatic effect of the polyphenylene sulfone, and can be used as an antistatic agent.

5. Compared with the common surfactant treated fiber, the hydrophilic group is formed on the surface of the fiber, the hydroxyl benzene sulfonic acid group and the polyphenylene sulfone are combined in a reaction manner, and the effects of stronger binding property and more lasting effect can be achieved.

The modified polypropylene and the antistatic agent are remixed, granulated and spun to form antistatic fiber; compared with the common surface treatment agent treatment for antistatic polypropylene fibers, the antistatic agent and polypropylene are melt mixed and then re-spun to form fibers, so that the combination mode is more stable, in addition, calcium dobesilate is used for modifying polyphenylene sulfone during preparation of the antistatic agent, and finally the obtained product is combined with modified polypropylene, so that the antistatic polypropylene fiber has excellent compatibility and the heat resistance and the aging resistance of the polypropylene are improved.

Detailed Description

With the rapid and dramatic increase in the production of synthetic fibers, the problem of spinning static electricity is becoming more acute, and the current antistatic methods can be classified into physical methods and chemical methods. The physical method comprises the following steps: (1) the relative humidity of the air is improved to improve the electrostatic leakage capacity of the fiber; (2) selecting different fibers with opposite electrification polarities to weave a fabric; (3) spraying a layer of metal film on the surface of the fiber by vacuum spraying to prepare metallized fiber; (4) short metal fibers or fiber bundles of stainless steel and chemical fibers are blended into composite conductive fibers; (5) carbon particles are embedded in the surface of the fiber to produce a carbon fiber. The chemical method comprises (1) adding chemical agent or antistatic agent into spinning solution of chemical fiber polymer to prepare antistatic fiber; (2) preparing metallized fiber by a chemical method; (3) chemically reacting the fiber with a substance; (4) the fibers are treated with a surfactant. Among these methods, the physical method has a certain limitation in use, and finishing of fibers with an antistatic agent is one of the common methods for antistatic fibers.

Among the antistatic agents used at present, the ionic type antistatic agent has good antistatic effect, but the ionic type antistatic agent mainly contains a nitrogen compound, is easy to change color in a high-temperature environment, and influences the dyeing of fibers and fabrics thereof; compared with ionic antistatic agents, the nonionic antistatic agents have the advantages of low toxicity, no stimulation to skin, emulsification and wetting effects, but poor adsorption to fibers and no ionization, so the antistatic effect is poor. The antistatic fiber which has the advantages of extremely low toxicity to human bodies, outstanding antistatic effect and strong heat resistance is prepared by using the polymer without toxic and side effects on the human bodies and using the electrostatic spinning method. The antistatic fiber is used for weaving antistatic clothes.

The invention is further described with reference to the following examples.
