Embodiment Construction

[0032] Such as figure 1 The graphene melt-blown cloth mask shown is a composite fabric made of polypropylene melt-blown cloth as the middle layer and two layers of non-woven fiber cloth as the upper and lower layers. It is cut and stitched (ironing), and then two ear straps are bonded together. . Graphene powder is scattered and adhered in the polypropylene melt-blown fiber, and the adhesion is that the graphene powder particles are partially embedded in the melt-blown cloth fiber, or the graphene powder is bonded on the surface of the melt-blown cloth fiber.

[0033] Graphene melt-blown cloth molding adopts the following process:

[0034] 1) Add graphene spraying equipment between the 0.5mm flat outlet of the melt-blown cloth and melt-blown fiber equipment and the cooling equipment;

[0035] 2) The melt-blown cloth is sprayed and melted into flocculent or reticular fibers, and when it is still in a state of high-temperature viscous flow, spray graphene powder (nano-scale pa...

Abstract

The invention discloses a graphene melt-blown fabric, a manufacturing process and a protective article thereof. Graphene powder is adhered to melt-blown fabric fibers in a distribution mode, the adhesion is that graphene powder particles are partially embedded into the melt-blown cloth fibers, or the graphene powder is adhered to the surfaces of the melt-blown cloth fibers, or the graphene powderis adhered to the fibers in a coating mode, and the graphene melt-blown fabric is compounded with non-woven fabric and then can be used for manufacturing the graphene melt-blown cloth protective article. The graphene melt-blown fabric has high adsorption and filtration performance, is capable of effectively removing harmful gas and preventing static electricity and tearing-resistant, and have better anti-virus and antibacterial effects.

Description

technical field [0001] The invention relates to a molding and post-processing technology of melt-blown cloth. Background technique [0002] Melt-blown cloth is the main raw material of masks and has good air filtering performance. The raw material of melt blown cloth is polypropylene. [0003] The conclusion of the article "Study on Polypropylene Bonding and Surface Treatment" published in the Journal of Tangshan Institute of Engineering and Technology, Issue 4 at the end of 1991, pointed out that the surface oxidation speed of polypropylene is accelerated under heating conditions, and more poles are formed on the surface. Sexual groups can form more hydrogen bonds with the adhesive, so as to obtain greater bonding strength", which gives this patent a useful inspiration, that is, the heated polypropylene fiber is easy to be well bonded with some additive materials Bonded together. Of course, the molten polypropylene can be embedded with additional materials such as particl...
