Abstract

The invention relates to the technical field of textiles, and specifically relates to a multifunctional non-woven fabric with a high a polymer coating and a production method. The multifunctional non-woven fabric takes super absorbent fiber, low melting point fiber, a graphene sizing agent and the like as raw materials, and is prepared through the steps of opening mixing, carding, lapping, needling, hot melting powder spreading, hot rolling adhesion, coating and the like. According to the multifunctional non-woven fabric with the high a polymer coating prepared with the method, an electromagnetic shielding function, water absorption and moisture prevention functions are smartly combined into one body, so that the range and application of industrial textiles are broadened, and simultaneously, the graphene coating is in wavy distribution, and the service life of the multifunctional non-woven fabric is prolonged. The multifunctional non-woven fabric is simple in manufacturing technology,high in production efficiency and convenient for industrial production on a large scale.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a polymer-coated multifunctional nonwoven fabric and a production method. Background technique [0002] Nowadays, various electronic devices have entered every aspect of our lives. Among these electronic devices, many are installed in outdoor environments. Some of these electronic devices installed outdoors may be affected by external electromagnetic interference or generate electromagnetic interference to other nearby electronic devices. Therefore, these electronic devices need to have better electromagnetic compatibility. This includes two requirements. On the one hand, it is required that the electromagnetic interference generated by the equipment in the environment during normal operation cannot exceed a certain limit; on the other hand, it is required that the equipment has a certain degree of anti-interference to the electromagnetic interference in the environment. Spen...
