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 a spinning collection device capable of direct weaving, which includes a collection ball, three driving wheels, a driving wheel controller and a spinning needle; the three driving wheels are arranged on the outer periphery of the The center of the ball emits three mutually perpendicular rays, and the three driving wheels are respectively located at the intersection of the surface of the collecting ball and the rays; each driving wheel includes a driving motor and a runner, and the runner is installed at the end of the output shaft of the driving motor. The outer edge of the wheel is provided with a circle of pulleys along the circumference, and the pulley is the part where the driving wheel contacts the collecting ball; the three driving wheels are respectively connected with the driving wheel controller, and the speed and direction of each driving wheel are controlled by the driving wheel controller; The silk needle is movably installed above the collecting ball, and the distance between the spinning needle and the collecting ball can be adjusted. The device of the invention can make the collecting ball rotate along any track by controlling the three driving wheels, and then can efficiently weave any fiber structure, and has universal applicability.

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...
