Problems solved by technology

Chinese patent CN 102713037B (disclosure date 2012.10.3) discloses a conductive fabric and its preparation method and equipment. Part of the conductive thread is woven into the fabric, and part of it is exposed to the outside of the fabric. The obtained conductive fabric can be quickly and conveniently combined with other components. The connection, applicability and productivity are improved, but the preparation method is more complicated and the weaving process is difficult
[0005] It can be seen from the above technology that the preparation method of the wire fabric prepared by the coating method is relatively simple, and the original performance of the fabric is not changed much while the conductivity is imparted. However, the conductive polymer in the prepared conductive polymer coated fabric The bonding force with the fabric is limited, and in order to make the conductivity of the fabric high, it is necessary to add a large amount of conductive substances, and the cost is high

Abstract

The invention provides a method for preparing a novel flexible conductive fabric by using a micro-sphere self-assembly technology. The method comprises the following steps: by adopting hollow conductive micro-spheres as conductive materials, finishing the fabric surface by adopting a plasma technology, densely and regularly arranging the hollow conductive micro-spheres on the fabric surface by utilizing the self-assembly technology, and forming dense conductive micro-sphere layers on the fabric surface. According to the method, the preparation method is simple and convenient, the materials do not need to be alternatively arranged layer by layer, the time and the labor are saved, the conductivity, mechanical strength and other performances of conductive preparation can be regulated by controlling the layer number of the hollow conductive micro-spheres, and the controllability is high. The wire fabric prepared by the method is high in flexibility, high in conductivity, good in strength and water vapor permeability and air permeability and high in comfort level, and the wearing performance change of the fabric is slight.
