[0004] When conductive fiber fabrics are used in garment production, a circuit must be formed between the garment material pieces to achieve antistatic function. Since the conductive fiber is a linear material, it is difficult to form a loop between the garment material pieces. At the same time, it is easy to follow up due to incomplete butt joint of the cut pieces, broken conductive fiber or broken holes in the fabric, resulting in the failure to form a conductive antistatic circuit, causing sparks due to static electricity, or the risk of electrostatic discharge breakdown.
If the surface of the fabric is treated with an antistatic chemical agent, the chemical antistatic agent will gradually be lost after cleaning and washing, and the antistatic effect will gradually decrease with the increase in the number of washings. The hidden dangers of sparks or electrostatic discharge breakdown due to static electricity will also occur

Abstract
The invention discloses a preparation method of a three-layer durable and difficult-to-hydrolyze electrostatic elimination microporous film. The preparation method includes the steps of implanting a second antistatic conductive layer and a third high moisture-permeable protective layer. The surface of the first layer of PTFE nano-microporous film is processed by high-precision surface treatment technology, and a specially formulated antistatic conductive layer is compositely implanted on the surface of the PTFE nano-microporous film; Insert the high moisture permeability protective layer, on the surface of the polytetrafluoroethylene nano-microporous film that has been implanted with the antistatic conductive layer, implant the specially formulated high moisture permeability protective layer on the surface of the antistatic conductive layer. The present invention implants the second layer of antistatic conductive layer and the third layer of anti-cleaning and high moisture permeability protective layer on the surface of the first layer of polytetrafluoroethylene nano-microporous film, so that the material can not only meet the international antistatic standard, but also be durable It is subject to professional grade requirements such as high-strength bending and flexing use and multiple industrial high-strength cycle washing.
Description
technical field [0001] The invention belongs to the technical field of new materials, and in particular relates to a preparation method of a three-layer structure durable and difficult-to-hydrolyze electrostatic elimination microporous film. Background technique [0002] In daily life, due to the dry climate, contact between the human body and objects is likely to cause static sparks or high-voltage electrostatic discharge breakdown due to the difference in static voltage potential between objects, especially in autumn and winter. In view of the professional fire protection industry, Petrochemical or natural gas industry, high-precision semiconductor industry, telecommunication equipment industry, aerospace defense industry and medical industry personnel are concerned about the potential explosion hazards caused by sparks or high-voltage electrostatic discharge breakdown due to environmental static electricity in the production and operation environment, and the impact of sta...
