Problems solved by technology

[0003] Disclosed a kind of anti-alcohol, anti-plasma, anti-static, anti-penetration functional non-woven fabric in the patent CN1821474A of China, though mentioned the formula of waterproofing agent, antistatic agent and penetration agent, but in the formula of waterproofing agent, there is no The macromolecules of the fluorocarbon resin in the emulsifier and waterproofing agent cannot exist in the form of emulsion, so the macromolecules of the fluorocarbon resin will easily form precipitation and lose the effect of water and oil repellency
[0004] Another example is disclosed in the Chinese published patent CN102321978A, which discloses a method for making a multifunctional SMS non-woven fabric. The type of penetrant contained in the non-woven fabric is a non-ionic surfactant, which will cause the water pressure resistance effect of the non-woven fabric. significantly reduce

Abstract

Waterproof oil-proof antistatic non-woven fabric and a producing method thereof are disclosed. The non-woven fabric comprises 0.28-1.35% by weight of fluorocarbon resin and 0.15-0.75% by weight of a phosphate type antistatic agent. The non-woven fabric is characterized by being high in hydraulic pressure resistance retention rate and being environmental friendly, and can be widely used in the fields of medical, sanitary, filtration, industries, catering services, and the like.

Description

technical field [0001] The invention relates to a waterproof, oil-proof, antistatic non-woven fabric and a production method thereof. The non-woven fabric can be widely used in the fields of medical treatment, sanitation, filtration, industry, catering and the like. Background technique [0002] With the sharp increase in the demand and output of non-woven fabrics, the functional requirements of various industries for non-woven fabrics are also getting higher and higher, and as human beings have stricter requirements on the environment, the C6 series of three-proof agents have become more and more popular. It is getting more and more attention, and it will replace the production of C8 series of three-defense agents by 2015. Because the three defense agents of the C8 series are relatively polluting to the environment, the half-life of the decomposition in the organism will reach about several years. The three-proof agent of C6 series is mainly reflected in fluorocarbon acryl...
