Abstract

The invention relates to a device for spinning a nanofiber and filament composite yarn; the device is characterized by comprising a left side spinning solution injector and a right side spinning solution injector, wherein the left side spinning solution injector and the right side spinning solution injector are connected with a high voltage power supply anode; receiving plates are connected with a high voltage power supply cathode; a left side filament leading-in device and a right side filament leading-in device are arranged on external sides of a left side receiving plate and a right side receiving plate; and winding devices are arranged below the left side receiving plate and the right side receiving plate. The device for spinning the nanofiber and filament composite yarn, provided by the invention, has the following technical steps of: (1) carrying out electrostatic spinning; (2) leading in filaments to the two nanofiber receiving plates during electrostatic spinning, so that the nanofibers adhere to the two filaments; and (3) twisting and combining the two filaments, so as to obtain the nanofiber and filament composite yarn. According to the invention, the obtained nanofiber and filament composite yarn has the advantages of ultrahigh specific surface area of the nanofiber and high-strength characteristic of the filament.

Description

Technical field

[0001] The invention relates to a composite yarn spinning method, in particular to a spinning device and a spinning method of a nanofiber and filament composite yarn, and belongs to the technical field of composite yarn production. Background technique

[0002] Electrospinning technology is an effective method for preparing nano-scale fibers and fiber membranes. However, the extremely low strength of nano-fibers and nano-fiber membranes is an important obstacle to their further application in related industrial fields. The strength of filaments, especially nylon filaments, is one of the popular features in industrial applications. If the nano effect of electrospinning nanofibers and the strength of filaments can be effectively combined to produce a new type of nano / filament composite yarn, it will open up new areas of industrial application of nanofibers.
