Problems solved by technology

In summary, electrospinning is one of the most direct, effective, simple and general methods for preparing nanofibers. However, due to the problem that electrospinning nanofibers cannot be produced industrially, there are also problems in obtaining PVA nanofiber yarns by this method. The problems of low efficiency and low output, and by cutting the film to obtain regular fibrous nanofiber yarns, the process control is difficult, which further brings difficulties to mass production

Abstract

The invention discloses a nano-fiber yarn and a preparation method thereof and belongs to the technical field of nano-fiber textile. The preparation method of the nano-fiber yarn comprises the steps of using a melt spinning technology to prepapre a nano-fiber protofilament; fixing the two ends of the nano-fiber protofilament; carrying out ultrasonic extraction on the nano-fiber protofilament in asolvent to prepare a nano-fiber tow; and twisting the nano-fiber tow to obtain the nano-fiber yarn. Compared with an electrostatic spinning method, the preparation method of the nano-fiber yarn, disclosed by the invention, has the advantages of high yield and efficient production; and meanwhile, as the nano-fiber yarn disclosed by the invention has the advantages of high mechanical strength, largespecific surface area and the like, the nano-fiber yarn disclosed by the invention can be used for weaving nano-fiber fabrics; and the nano-fiber yarn is further applied to the technical fields of adsorption, catalysis, electric conduction, antibacterial and the like.

Description

technical field [0001] The invention relates to a nanofiber yarn, belongs to the technical field of nanofiber textiles, and in particular relates to a nanofiber yarn and a preparation method thereof. Background technique [0002] In the traditional textile industry, fibers and yarns are the most widely used subject materials. However, as far as the current textile processing technology is concerned, only fibers with a diameter of at least 10 microns can be produced. Nanofibers have many novel properties, such as volume Effect, surface effect, etc. If nanotechnology can be introduced into the traditional textile industry, it can improve the status quo of the textile industry and process high value-added functional textiles. The current definition of nano-yarns is that a layer of nano-fibers is wrapped on the surface of conventional yarns, which is called nano-yarns, which are not directly composed of nano-fibers. [0003] For example, the Chinese invention patent application...
