Problems solved by technology

However, in the existing electromagnetic materials, the magnet and the conductive coil are basically heavy hard materials, and it is difficult to make fabrics. In this patent, the magnet unit and the electromagnetic induction unit are sewn, pasted or bound. When fixed on the main body, the joint between the magnet unit and the electromagnetic induction unit and the main body will have the problems of hard texture and poor flexibility, which will seriously affect the wearing comfort of the power-generating clothes, resulting in poor user experience and limiting Applied to make clothes that can generate electricity

Embodiment 1

[0040] This embodiment provides a production method of a swing electromagnetic induction power generation flexible fabric, including a production method of a magnetic yarn fabric and a production method of a conductive coil fabric.

[0041] The production method of described magnetic yarn fabric is as figure 1 As shown, it specifically includes the following steps:

[0042] A1, preparation of fiber strip S1

[0043] Set the areal density to 20g / m 2 The non-woven flexible surface material roll is installed on a cutting machine, cut into fiber strips S1 with a linear density of 100g / km, and then wound on a bobbin to obtain a fiber strip S1 package.

[0044] A2. Preparation of magnetic powder prepolymer S2'

[0045] The magnetic powder is demagnetized, and the surface density is 20g / m 2 Adhesive tape S2 rolls are installed at the rear end of the padding machine, after peeling off the anti-sticking strip on the surface of the adhesive tape S2, the remaining adhesive tape is im...

Embodiment 2～3

[0065] Embodiments 2 to 3 respectively provide an application of a swinging electromagnetic induction generating flexible fabric. Among them, in Example 2, the swinging electromagnetic induction type power generation flexible fabric produced in Example 1 is applied to the power generation top, and its structural diagram is as follows Figure 4 shown; embodiment 3 then applies the swing electromagnetic induction type power generation flexible fabric produced in embodiment 1 to power generation pants, and its structural schematic diagram is as follows Figure 5 shown.

[0066] Depend on Figure 4 It can be seen that in Example 2, when the oscillating electromagnetic induction type power generation flexible fabric produced in Example 1 is applied to the power generation upper garment, the magnetic yarn fabric is sewn on the side of the garment body of the upper garment, and the conductive coil fabric is sewn on the garment body On the inner side of the sleeve with opposite side...

Abstract

The invention discloses a swing electromagnetic induction type power generation flexible fabric, a production method and application thereof. The oscillating electromagnetic induction type power generation flexible fabric of the present invention includes magnetic yarn fabrics and conductive coil fabrics respectively located on the surfaces of two relative swinging parts; the magnetic yarn fabrics include magnetic yarn cores formed by composite fiber strips wrapping magnetic powder; the The conductive coil fabric is formed by embroidery of conductive silk core-spun yarn strands on the fabric substrate. In the present invention, the magnetic powder is evenly wrapped in the yarn, and a stable magnetic yarn fabric is prepared by a weaving method, and then used in combination with a conductive coil fabric containing conductive filaments to produce a flexible fabric that can generate electricity; Flexible fabrics can be applied to clothing, and use electromagnetic induction to convert the mechanical energy generated by the human body's arm swing / walking process into electrical energy, which ensures the softness of the clothing while realizing power generation, meets the needs of actual use, and has great application value.

Description

technical field [0001] The invention relates to the technical field of functional textile processing, in particular to a swinging electromagnetic induction power generation flexible fabric and its production method and application. Background technique [0002] The phenomenon of electromagnetic induction refers to the phenomenon of induced electromotive force generated by the change of the magnetic flux passing through the closed loop. Human beings have opened up a way to obtain huge and cheap electric energy, which is of great practical significance. After this phenomenon was first discovered by Faraday, self-generating devices based on electromagnetic induction began to appear one after another, and gradually became an important energy harvesting device. [0003] In the process of human activities, the swinging process of hands and feet can generate mechanical energy. If the principle of electromagnetic induction can be used to collect this mechanical energy and convert i...
