Abstract (en)
A melt-blown non-woven fabric manufacturing method includes a melt-blown material supply step to supply a melt-blown material, an antibacterial agent pre-implanting step to add an antibacterial agent to the supplied melt-blown material, a melt mixing step to melt the melt-blown material and mix the molten melt-blown material with the antibacterial agent, a melt-blown forming step to spray the mixture of the molten melt-blown material and the antibacterial agent into filaments, and a cooling step to cooling the filaments, thereby forming an antibacterial agent pre-implanted melt-blown non-woven fabric. This method only needs to add the antibacterial agent in the pre-implanting step, and the antibacterial agent pre-implanted melt-blown non-woven fabric can be formed at the end of the process, so the process can be simplified. The melt-blown non-woven fabric produced by this technology can be used to replace the water-repellent non-woven fabric to provide the first layer of the mask.
