Embodiment 1

[0041] Such as Figure 4 As shown, in this embodiment, the spinning and collecting equipment that can be directly woven is used for dry spinning to obtain acetate fibers with a "cross" weaving structure.

[0042] S1. Dissolve diacetate in acetone solution, and keep stirring at a high speed in a constant temperature water bath at 30°C;

[0043] S2. Adjust the upper support arm 50 so that the spinning needle 60 is 20cm away from the top of the collection ball 10; set the speed program of the drive wheel 20, first the drive wheel 20X rotates at 90° / s for 16s, so that the collection ball 10 rotates one circle on the Y-Z plane, Then the driving wheel 20Y rotates at 90° / s for 16s, so that the collecting ball 10 rotates one circle in the X-Z plane, completes a cycle, and runs cyclically with this program;

[0044] S3. use the peristaltic constant flow pump 80 to draw the mixed solution to the spinning needle 60, and extrude from the needle, the solvent acetone in the spinning soluti...

Embodiment 2

[0046] Such as Figure 5 As shown, in this embodiment, blow spinning is performed using a spinning collection device that can be directly woven to obtain polyvinylpyrrolidone nanofibers with a "cross" weaving structure.

[0047] 1. Dissolve polyvinylpyrrolidone in the aqueous solution and keep stirring at a high speed in a constant temperature water bath at 30°C;

[0048] 2. Adjust the upper support arm 50 so that the spinning needle 60 is 20cm away from the top of the collection ball 10; set the speed program of the driving wheel 20, firstly the driving wheel 20X rotates at 360° / s for 4s, so that the collection ball 10 rotates one circle on the Y-Z plane, Then the driving wheel 20Y rotates at 360° / s for 4s, so that the collecting ball 10 rotates once in the X-Z plane, completes a cycle, and runs in this program cycle;

[0049] 3. Use the peristaltic constant flow pump 80 to pump the mixed solution to the spinning needle 60, turn on the high-pressure air pump 90, the high-spe...

Embodiment 3

[0051] Such as Figure 6 As shown, in this example, a spinning and collecting device that can be directly woven is used for electrospinning to obtain silica nanofibers with a "cross" weaving structure.

[0052] 1. Mix tetraethyl orthosilicate with the aqueous solution, hydrolyze it for 6 hours, add it to the beaker of the constant temperature water bath, then add 3% polyethylene oxide to dissolve, and keep stirring at a high speed in the constant temperature water bath at 30°C;

[0053] 2. Adjust the upper support arm 50 so that the spinning needle 60 is 10cm away from the top of the collection ball 10; the collection ball 10 is wrapped with a layer of aluminum foil paper, and the speed program of the driving wheel 20 is set. First, the driving wheel 20X rotates at 360° / s for 4s, Make the collection ball 10 rotate one circle on the Y-Z plane, then the driving wheel 20Y rotates at 360° / s for 4s, make the collection ball 10 rotate one circle on the X-Z plane, complete one cycle,...

Abstract

The invention relates to spinning collecting equipment capable of achieving direct weaving. The spinning collecting equipment comprises a collecting ball, three driving wheels, a driving wheel controller and a spinning needle. The three driving wheels are arranged at the periphery of the collecting ball and are perpendicular to one another in space, and if three rays perpendicular to one another are emitted from the center of the collecting ball, the three driving wheels are located at the intersection points of the surface of the collecting ball and the rays respectively. Each driving wheel comprises a driving motor and a rotating wheel, the rotating wheel is installed at the end of an output shaft of each driving motor, and a circle of pulley is arranged at the outer edge of each rotating wheel in the circumferential direction and is the part where each driving wheel makes contact with the collecting ball; the three driving wheels are respectively connected with the driving wheel controller, and the rotating speed and the direction of each driving wheel are controlled through the driving wheel controller; and the spinning needle is movably installed above the collecting ball, andthe distance between the spinning needle and the collecting ball can be adjusted. According to the equipment, the collecting ball can rotate along any track by controlling the three driving wheels, then any fiber structure can be efficiently woven, and universality is achieved.

Description

technical field [0001] The invention relates to the technical field of fiber manufacturing, in particular to a spinning collection device capable of direct weaving and a fiber weaving method. Background technique [0002] Fiber is a natural or synthetic filamentary substance. In modern life, the application of fiber is ubiquitous. However, it is difficult to form high-strength materials simply by disorderly arrangement of fibers. In order to improve the mechanical properties of fibers, it can be made into a fabric structure with a certain geometric shape in two-dimensional or three-dimensional space by textile technology. [0003] In 2018, Nature published a paper disclosing the reason why spider silk has excellent mechanical properties. Spider silk is composed of organic polymer proteins, but its strength is more than 5 times that of steel wire. At the same time, spider silk also has excellent torsion resistance in space. The reason is that spider silk is spatially a highl...
