Problems solved by technology

However, nano-silver / copper antibacterial agents are easily absorbed by the internal organs of the human body, and will accumulate and cause disease, endangering human health, and the United States and other European and American countries prohibit the use of nano-silver as an antibacterial agent
The antibacterial effect and stability of natural antibacterial materials are relatively poor, while the non-woven fabrics prepared by organic synthetic antibacterial materials have defects such as instability and low toxicity.

Abstract

The invention relates to a zinc-based antibacterial non-woven fabric and a preparation method thereof. The zinc-based antibacterial non-woven fabric is prepared by preparing a zinc-based nano-antibacterial dispersion liquid, mixing the zinc-based nano-antibacterial dispersion liquid with a dispersant and a synergist, carrying out dipping treatment on a polypropylene fiber non-woven fabric, and drying the polypropylene fiber non-woven fabric. The zinc-based antibacterial non-woven fabric is green, environment-friendly, non-toxic, non-irritating, short in antibacterial action time and lasting inantibacterial effect, and has excellent properties of good stability, no decomposition when meeting light and heat and the like.

Description

technical field [0001] The present invention relates to an antibacterial nonwoven fabric; more particularly, the present invention relates to a zinc-based antibacterial nonwoven fabric. In addition, the invention also relates to a preparation method of the zinc-based antibacterial nonwoven fabric. Background technique [0002] As the most cost-effective and highly flexible non-woven fabric technology, spunbond / spunmelt non-woven fabrics occupy the largest share of the entire market. Although needle punching, spunlace, hot air and other technologies are also popularizing and joining the competition, but The output is still far behind the spunbond / spunmelt technology. According to the analysis and forecast released by Price Hanna Consulting Company, it is expected that the global spunbond / spunmelt nonwovens will increase to about 4.8 million tons from 2017 to 2022, equivalent to 1.8%. Annual growth rate (this forecast data does not include the yet-to-be-announced capacity exp...
