Problems solved by technology

Through the analysis of the existing nanofiber bundle preparation technology, it is found that although the bundled method of nanofibers has been developed to a certain extent in recent years, the bundled state of the fibers is not good, and the degree of orientation and stretch is poor, so the mechanical properties are poor.

Abstract

The invention relates to a preparation device and method for a high strength nanofiber bundle. The preparation device comprises an injector, a spray head arranged at on output end of the injector anda water disc arranged below the spray head, and the water disc comprises a liquid storage groove and two parallel electrode plates arranged inside the liquid storage groove. According to the preparation device and method for the high strength nanofiber bundle, an electrostatic spinning method is adopted, the nanofibers are deposited in bath liquid which is provided with the parallel electrode plates, after the nanofibers undergo bundling and winding, the high strength nanofiber bundle is obtained. The parallel electrode plates in the bath liquid can make the nanofibers present a highly oriented state when nanofibers are deposited in the bath liquid, thereby after the water bath bundling, the nanofibers present high orientation degree and extension degree, the strength utilization rate of the nanofibers is improved, the mechanical strength of the nanofiber bundle is also improved, the prepared nanofiber bundle can be directly applied to the three-dimensional textile processing, therebythe nanofibers can be better applied to the fields of extreme lightweight textiles, intelligent textiles, sensors and biomedical materials.

Description

technical field [0001] The invention relates to a fiber preparation device, in particular to a preparation device for high-strength nanofiber bundles, and also relates to a preparation method for high-strength nanofiber bundles. Background technique [0002] Nanofibers have extremely high specific surface area, excellent surface properties and flexible mechanical properties, so they have important application potential in the fields of environmental protection, personal protection, biomedicine, chemical catalysis, sensors, energy storage and power generation, electronics, clothing and military . [0003] At present, various methods can be used to produce nanofibers, such as electrospinning method, sea-island method, melt blown method, etc. Comprehensive comparison, electrospinning technology has a wide range of material selection, simple process operation, strong controllability, fiber diameter, The orientation and physical shape can be adjusted, and the outstanding advanta...
