Abstract

The invention relates to a spherical opposite-spraying type batched nanofiber yarn processing device and a using method thereof. The device comprises a body and a base. Crossed wedge grooves are formed in the middle of the base. The body is symmetrically arranged on the second wedge groove along the first wedge groove. The body comprises a liquid supply system, a separation electric field control system, a spherical brush type spinneret system, a nanofiber yarn forming system and a nanofiber yarn collecting system. The liquid supply system comprises an air cylinder, a spinning solution storage bottle, an oil bath groove and a liquid guiding pipe. The spinning solution storage bottle is arranged inside the oil bath groove. The spinning solution storage bottle, the liquid guiding pipe and a liquid brushing groove form a communicating vessel structure. The spinning solution storage bottle is connected with the air cylinder through an air pipe. A main valve and a pressure reduction valve are sequentially arranged at the portion, close to the air cylinder, of the air pipe. Due to the liquid supply system adopting the air pressure communicating vessel, automatic supply of a high polymer solution can be achieved, and the device is simple and easy to use, and convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of nanometer electrospinning and textile machinery, and in particular relates to a spherical pair-brush type batch nanofiber yarn processing device and a method for using the same. Background technique [0002] When polymer fiber diameters are reduced from the micrometer scale to the submicrometer or nanometer scale, a surprising set of properties emerges. Such as a very large volume specific surface area, the volume specific surface area of ​​nanofibers is basically 1000 times that of microfibers; it can be flexibly functionalized on the surface; it shows superior effects and mechanical properties compared with other known material forms, such as surface And interface effect, small size effect, quantum size effect and quantum tunneling effect and stiffness, tensile strength, etc. These outstanding properties make nanofibers the material of choice for many important applications, and have great development ...
