Abstract

The invention relates to nano-silver antibacterial melt-blown non-woven fabric and a production method thereof. The nano-silver antibacterial melt-blown non-woven fabric is characterized in that the fabric contains hybrid nanoscale antibacterial powder, a non-woven fabric base stock can be polypropylene, polyester or polyphenylene sulfide, the hybrid nanoscale antibacterial powder is formed in a way that nanoscale zirconium phosphate and silver nitrate are exchanged in water to form silver phosphate, zinc oxide needs to be added in the exchange process, and the antibacterial powder has the proportion of ingredients as follows: 2-5 percent of the silver nitrate, 90-95 percent of the zirconium phosphate and 1-5 percent of the zinc oxide. The nano-silver antibacterial melt-blown non-woven fabric has excellent inhibition and stop effects on escherichia coli, staphylococcus aureus, Candida albicans and the like, and can filter various particles with the pm (particulate matter) over 2.5 in current air haze, the filter efficiency is over 95 percent, and the antibacterial ratio is over 99 percent; the fabric is tested by sgs (Societe Generale de Surveillance); the prepared nano-silver antibacterial melt-blown non-woven fabric is good in strength, not easy to break, soft and comfortable.
