Abstract

The invention relates to the technical field of textiles and particularly relates to a multifunctional coated non-woven fabric and a preparation method thereof. The multifunctional coating non-woven fabric comprises a super-absorbent fiber layer, a low-melting-point fiber layer and a graphene coating, wherein the super-absorbent fiber layer is arranged at the lower part of the low-melting-point fiber layer, the graphene coating is coated on one side of the low-melting-point fiber layer, part of the fibers of the low-melting-point fiber layer extend into the super-absorbent fiber layer, and part of the fibers of the super-absorbent fiber layer extend into the low-melting-point fiber layer. The multifunctional coated non-woven fabric prepared by the method skillfully integrates an electromagnetic shielding function with a water absorption functions, moisture resistance and the like, widens the range and application of industrial textiles, meanwhile, the multifunctional coated non-woven fabric has simple manufacturing process and high production efficiency, and is convenient for mass industrial production.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a multifunctional coated nonwoven fabric and a preparation method thereof. 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. Spe...
