Problems solved by technology

[0003] In some R&D and production workshops, operators often need to be in contact with some acidic or alkaline liquids. At the same time, when working in the workshop, they also need to be exposed to electromagnetic waves for a long time. Based on this situation, in order to protect the physical safety of operators, we need to develop a A fabric with excellent acid and alkali resistance and electromagnetic shielding performance, but the existing fabric cannot meet our needs

Abstract

The invention discloses acid and alkali resistant fabric special for special clothing and a processing technology of the acid and alkali resistant fabric. The acid and alkali resistant fabric comprises pretreatment base cloth and a surface modifier. The pretreatment base cloth is aramid fiber base cloth with the surface treated by oxygen plasma, oxygen plasma surface treatment can promote cracking, oxidation, transfer and other effects generated to free radicals on the surface of the aramid fiber base cloth, and therefore a large number of oxygen-containing active groups are generated, the oxygen-containing active groups can be chemically bonded with epoxy groups in epoxy resin, and the interfacial adhesion of the aramid fiber base cloth and the epoxy resin is improved; and process designis reasonable, operation is simple, the prepared fabric has excellent corrosion resistance and acid and alkali resistance, meanwhile, the fabric can realize relatively excellent electromagnetic shielding performance, and the fabric can be applied to multiple fields and has relatively high practicability.

Description

technical field [0001] The invention relates to the technical field of fabrics, in particular to a special acid and alkali resistant fabric for special clothing and its processing technology. Background technique [0002] Special clothing refers to those clothing with special functions or special purposes, which are used in occasions with special requirements during work, such as acid-proof clothing, fire-proof clothing, oil- and water-repellent clothing, anti-static clothing, flame-retardant clothing, welding protective clothing, anti-corrosion Arc clothing, etc., the use of the clothing limits the preparation direction of the fabric, which also puts forward higher requirements for the quality of the fabric. [0003] In some R&D and production workshops, operators often need to be in contact with some acidic or alkaline liquids. At the same time, when working in the workshop, they also need to be exposed to electromagnetic waves for a long time. Based on this situation, in ...
