Problems solved by technology

However, in cold weather, this type of product cannot be used due to wearing non-conductive gloves, which greatly limits the use environment of the product. Therefore, it can be predicted that the market demand for synthetic leather with low resistivity as conductive glove leather will be considerable. huge
[0003] However, the current method is to add conductive materials such as carbon black to wet-process polyurethane, and then impregnate them into the base fabric. Stable, and there will be black spots on the surface of the base cloth

Abstract

The invention discloses conductive microfiber synthetic leather and a production method thereof. The production method comprises the following steps: (1) conductive color masterbatch is obtained from carbon black, a carbon nano tube, graphene, a dispersing agent, a heat stabilizer, an antioxidant and nylon through mixed granulation; (2) the conductive color masterbatch obtained in the step (1) is mixed with nylon 6 for melt spinning, and the conductive microfiber synthetic leather is prepared. A conductive material is dispersed into the color masterbatch and uniformly dispersed into fibers, so that the product performance is stable, base fabric surface is not affected, preparation steps are simple, the problems of non-uniform conductivity and poor durability are solved effectively, and the durability of the original product is improved greatly.

Description

technical field [0001] The invention relates to a superfiber synthetic leather with conductive function. Background technique [0002] With the development of science and technology, capacitive touch screen products have become popular all over the world. With the further development of this trend, touch control, a new human-computer interaction mode, is widely used in all aspects of life. However, in cold weather, this type of product cannot be used due to wearing non-conductive gloves, which greatly limits the use environment of the product. Therefore, it can be predicted that the market demand for synthetic leather with low resistivity as conductive glove leather will be considerable. huge. [0003] However, the current method is to add conductive materials such as carbon black to wet-process polyurethane, and then impregnate them into the base fabric. Stable, and there will be black spots on the surface of the base cloth. Contents of the invention [0004] The purpo...
