Embodiment 1

[0025] The polyacrylonitrile spinning solution with a mass fraction of 12% (the solvent is N,N-dimethylformamide) is spun into nano Fiber, when spinning, the included angle of spinneret head (9) and motor 1 central axis is 30 degrees, and opposite direction draws yarn (7), makes the nanofiber that generates draw yarn (7) and the receiver of rotation ( 4) connect, the rotating speed of receiver (4) is 20r / min; Nanofiber forms an orientated funnel-shaped nanofiber net (8) at drawing yarn (7) and the receiver (4) of rotation gradually, then Under the rotation of the yarn guide tube (5), the yarn guide (7) is driven to continuously bundle the nanofibrous web (8) into yarns, and the rotating speed of the yarn guide tube (5) is 100r / min; 6) Wind the bundled yarn at a speed of 7.8r / min.

[0026] The whole process of adopting the present invention to prepare polyacrylonitrile nanofiber yarn is as follows: figure 2 shown. (a) is a photo of a funnel-shaped nanofiber web; (b) and (c)...

Abstract

The invention relates to a continuous production device and method of orientation nanometer fiber yarns. The continuous production device comprises a yarn bobbin (6), a yarn guiding pipe (5) and a receiver (4); the yarn bobbin (6) is driven by a motor (2) to rotate and is located above the yarn guiding pipe (5); the yarn bobbin (6) and the yarn guiding pipe (5) are perpendicular to each other; the yarn guiding pipe (5) and the motor (2) are fixed on a rotating shaft of a motor (1); the receiver (4) is driven by a motor (3) to rotate; the axes of the motor (1) and the motor (3) are located on the same straight line. According to the continuous production device and method of the orientation nanometer fiber yarns, the continuous production of the nanometer fiber yarns is achieved and the application in the biological, textile, material and electronic fields of nanometer fibers is expanded.

Description

technical field [0001] The invention belongs to the technical field of nanofiber yarn preparation, and in particular relates to a continuous preparation device and method for oriented nanofiber yarn. Background technique [0002] Nanofibers have four major effects: surface effect, small size effect, quantum size effect, and macroscopic quantum tunneling effect, and exhibit excellent physical and chemical properties such as light, electricity, magnetism, and force. Electronic devices, nanosensors, filtration and separation, biomedicine, protective clothing and many other fields have a wide range of potential applications. At present, the product form of nanofibers is basically a fiber mat in a random arrangement state. Although this sheet material can be directly applied, the secondary processability and mechanical properties of the product are poor. The preparation of nanofibers into a one-dimensional continuous yarn structure can solve the problems of poor mechanical prope...
