  • a mask with sterilization function disclosed in China Patent No. CN106102863 .
  • the production method is to first form a microfiber coating on a microfiber substrate.
  • the microfiber coating is made of interwoven submicron fibers and nanofibers, and then biocide is introduced into the micron and nanofibers to form a mask with bactericidal function through encapsulation, surface attachment, blending, physical capture or chemical cross-linking.
  • the mask with sterilization function disclosed in the aforementioned Chinese patent has more complicated and cumbersome manufacturing processes.
  • this antibacterial non-woven fabric If someone wants to do a subsequent waterproof treatment on this antibacterial non-woven fabric to make it have the function of preventing blood spray, but because this antibacterial non-woven fabric has been treated by physical or chemical methods to coat the antibacterial agent on the microfiber, if it is to be waterproofed again, the waterproof coating at this time will no be able to cover the entire antibacterial non-woven fabric. Due to this problem, the antibacterial non-woven fabric that is unevenly covered by the waterproof coating will not pass the national mask waterproof test standard.

It is therefore the main object of the present invention to provide a method for manufacturing a melt-blown non-woven fabric for mask, by adding an antibacterial agent in the melt-blown material in advance during the melt-blown non-woven manufacturing process and mixing them uniformly. In this way, only one melt-blown forming step is required to form a melt-blown non-woven fabric with pre-implanted antimicrobial. Since this melt-blown non-woven fabric has not undergone any physical or chemical coating treatment with antibacterial agents, it can be subjected to subsequent waterproofing treatment, so it can be used as the outer layer of a mask.
