Problems solved by technology

Although conductive fiber has excellent electrical properties, it has poor flexibility, is not resistant to bending, and is expensive. In the spinning process, improper blending ratio will cause a lot of waste and increase the difficulty of the weaving process. It is subject to certain limitations in the application of textiles. , while the method of conductive coating increases the thickness and hardness of the fabric on the one hand, and the wearing comfort is poor. On the other hand, the washing resistance is poor, the coating is easy to fall off, and it also has many defects during use.

Abstract

The invention provides an elastic conductive composite fabric and a preparation method thereof. The elastic conductive composite fabric is characterized by comprising spandex elastic fabric, an adhesive layer, a flexible nano-conductive film, another adhesive layer and spandex elastic fabric from the top to the bottom in sequence. The conductive composite fabric prepared according to the preparation method of the invention has good electrical conductivity (10<3>S/m to 10<5>S/m), good elasticity and high elongation (20% to 50%), and can bear bending and compression deformation. The elastic conductive composite fabric can be used in the production of intelligent wearable clothing, and has wide application in the fields of intelligent textile structures and intelligent materials.

Description

technical field [0001] The present invention relates to the field of smart textiles, more particularly, to the field of elastic conductive composite textiles. Background technique [0002] In recent years, with the rapid development of science and technology and the Internet, the research and development and application of smart textiles and wearable electronic products have become more and more extensive, and conductive fabrics can be conductive and wearable at the same time. Demonstrate significant research value and application potential. [0003] Most of the conductive fabrics currently on the market are made by blending conductive fibers or conductive coatings. Although conductive fibers have excellent electrical properties, they have poor flexibility, are not resistant to bending, and are expensive. In the spinning process, improper blending ratio will cause a lot of waste, increase the difficulty of the weaving process, and be limited in the application of textiles. ...
