Abstract

The invention relates to the technical field of textiles, in particular to a polymer-coated multifunctional nonwoven fabric and a production method. The multi-functional non-woven fabric adopts raw materials such as superabsorbent fiber, low-melting point fiber and graphene slurry, through opening and mixing, carding, laying, needle punching, sprinkling hot melt powder, hot rolling bonding, coating, etc. steps are made. The polymer-coated multifunctional nonwoven fabric prepared by the present invention skillfully integrates electromagnetic shielding function and water absorption and moisture-proof functions, broadens the scope and application of industrial textiles, and the graphene coating is distributed in a wave shape , prolong the service life of multifunctional nonwovens. The manufacturing process of the invention is simple, the production efficiency is high, and it is convenient for large-scale industrial production.

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...
