Nano-silver antibacterial melt-blown non-woven fabric and production method thereof

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.

Description

technical field [0001] The invention relates to a nano-silver antibacterial melt-blown nonwoven fabric and a production method thereof. The invention belongs to the technical field of antibacterial nonwoven fabric production. Background technique [0002] With the development of industrialization, the increase of population, the increase of harmful substances in the air, the smog is getting more and more serious, the traditional mask cloth can no longer meet people's needs, nano-silver antibacterial non-woven fabrics are effective against Escherichia coli, Staphylococcus, Bacteria, etc. have a good inhibitory and blocking effect. The emergence of nano-silver antibacterial non-woven fabrics has greatly met people's increasing requirements and needs for air pollution isolation, and has also been recognized by consumers.

AI Technical Summary

Problems solved by technology

[0002] With the development of industrialization, the increase of population, the increase of harmful substances in the air, the smog is getting more and more serious, the traditional mask cloth can no longer meet people's needs, nano-silver antibacterial non-woven fabrics are effective against Escherichia coli, Staphylococcus, Bacteria, etc. have a good inhibitory and blocking effect. The emergence of nano-silver antibacterial non-woven fabrics has greatly met people's increasing requirements and needs for isolation of air pollution, and has also been recognized by consumers.

[0003] CN101301488A discloses a kind of antibacterial superfine fiber non-woven fabric embedded with nano-silver, its process is complicated, and can not be used for preparing mouth mask;

[0004] CN101824746A discloses the preparation of a nano-silver spunlace non-woven fabric composite antibacterial material. The spunlace method is used to prepare the non-woven fabric, the fiber is thicker, and the comfort is poor

[0005] Using the melt-blown process, ultra-fine denier non-woven fabrics can be prepared, which are soft and comfortable, and can be used as mask materials, but none of the existing melt-blown non-woven fabrics has antibacterial properties.

This is because the addition of nano-silver antibacterial powder, due to its fine particle size, easy clumping, poor dispersion, and low strength, it is difficult to spray out when using the melt-blown process; even if it is sprayed out, the fibers are easy to break, so that it cannot be made into cloth.
