Problems solved by technology

However, the disadvantage of this method is that the electromagnetic induction unit coil and the magnet unit need to be glued or pasted on the clothes, which will lead to poor flexibility and heavy weight of the clothes, which cannot well meet the requirements of flexible wearable clothing.
[0006] The above prior art shows that in the existing electromagnetic materials, the conductive coils and magnets are basically hard materials, and the quality is relatively heavy, so it is difficult to make fibrous or fabric-like materials.

Abstract

The invention provides a fabric for generating electricity by mean of airflow and a preparation method and application of the fabric. The fabric is in a double-layer structure design, and comprises asurface layer fabric and an inner layer fabric which are overlapped with each other but not interwoven, as well as an airflow space which is formed between the surface layer fabric and the inner layerfabric; at least one opening is formed in the surface layer fabric; and one of the surface fabric and the inner fabric is a flexible magnetic yarn fabric, and the other is a flexible conductive yarnfabric. With the arrangement, external airflow can enter the airflow space in the middle of a double-layer structure through the opening for circulation to drive the surface layer fabric to generate deformation and cut magnetic induction lines to generate electromagnetic induction current, so that the electricity generation function is realized, the defect that an existing wearable device can be used normally only by relying on external power supply or cooperating with an energy storage device is overcome, and the development of the wearable device in the trend of light weight, convenience andintelligence is facilitated. The preparation method provided by the invention is simple to operate, and the composition, structure and performance of a material can be adjusted and controlled according to the practical application.

Description

technical field [0001] The invention relates to the technical field of functional textile processing, in particular to a fabric generating electricity by means of air flow, its preparation method and application. Background technique [0002] At present, the research and product development of wearable technology and wearable devices are relatively popular. The design of wearable devices emphasizes lightness, flexibility and comfort. Whether it is the overall design or the matching of components, the weight and volume restrictions are relatively strict. One of them is Requirements for power and battery life. Most wearable device products need to rely on external power supply or work with energy storage devices to work normally, so large-scale applications are subject to certain restrictions. In the long run, flexible wearable devices that generate self-supplied energy are the future development trend of wearable technology. [0003] The phenomenon of electromagnetic induct...
