Problems solved by technology

The present invention also enables graphene to be applied in the textile field through a certain process to exert its special function. The fabric has excellent antistatic and conductive properties. There are two common conductive fibers on the market at present, one is similar to spinning masterbatch The conductive filament spun from conductive materials is added to it, but its quality is unstable due to uneven dispersion, high resistance, and unstable quality; the other is an all-metal conductive fiber similar to aluminum and stainless steel fibers, but its weaving also causes damage to the knitting needles, and Its material properties are different from those of polyester, and there are many defects on the fabric surface, which are difficult to control

Description

technical field [0001] The invention belongs to the field of textile fabric processing, in particular to a preparation process of a graphene-coated fabric. Background technique [0002] With the development of science and technology, new materials have been discovered and applied one after another. Among them, the appearance of graphene is known as the material that will change the 21st century, and it is known as the black gold in the material industry. Graphene is a two-dimensional crystal composed of carbon atoms with only one atomic thickness. Graphene is not only the thinnest material, but also the strongest material, with a fracture strength 200 times higher than the best steel. At the same time, it has good elasticity, and the stretching range can reach 20% of its own size. It is currently the thinnest and strongest material in nature. If a piece of graphene with an area of ​​1 square meter is used to make a hammock, it can bear a cat weighing one kilogram with a wei...
