NOVELTY - Antibacterial and anti-ultraviolet high-efficiency low-resistance micro-nano fiber mask fabric comprises an inner layer, a middle layer and an outer layer, where the inner layer is a hydrophilic layer, the middle layer is a nanofiber film containing a photocatalytic composite antibacterial agent, and the outer layer is a hydrophobic layer. USE - Antibacterial and anti-ultraviolet high-efficiency low-resistance micro-nano fiber mask fabric used in a textile field and to a textile fabric material, an antibacterial UV resistance, a photo-catalytic antibacterial agent e.g. titanium oxide, zinc oxide, and magnesium oxide, an oxide semiconductor material, electrical properties, optical properties and chemical stability, an electron on the valence band can absorb the energy in the ultraviolet light transition, and the ability of absorbing and shielding ultraviolet and light catalytic antibacteria. ADVANTAGE - The antibacterial and anti-ultraviolet high-efficiency low-resistance micro-nano fiber mask fabric is cost-effective and save energy, has high specific surface area and large porosity of the nano fibre, unique structure and excellent performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing an antibacterial and anti-ultraviolet high-efficiency low-resistance micro-nano fiber mask fabric, which involves: a. dissolving the polymer nanofibers with an organic solvent to obtain a polymer nanofiber solution, adding a photocatalytic composite antibacterial agent to the polymer nanofiber solution, ultrasonicating, then stirring and defoaming at room temperature to obtain a photocatalytic composite antibacterial polymer nanofiber solution as spinning solution; b. electrospinning the spinning solution, using PP spunbonded nonwoven fabric as a receiving substrate to prepare PP spunbonded nonwoven fabric-nanofiber film; and c. covering a layer of viscose spunlace nonwoven fabric on the nanofiber film surface of the PP spunbonded nonwoven fabric-nanofiber film, using viscose spunlace nonwoven fabric as the inner layer, cutting and bonding to obtain a product.
