Description

Non-woven mop base cloth with antibacterial function and preparation method thereof

Technical Field

The invention relates to the technical field of non-woven mops, in particular to a non-woven mop base fabric with an antibacterial function and a preparation method thereof.

Background

The non-woven mop is usually made of a plurality of layers of non-woven base cloth through long ultrasonic heat bonding, and has the advantages of low cost, simple manufacturing process and easy use and treatment. Common non-woven mops on the market generally do not have an antibacterial function, and when the mops are actually used, the mops are in a wet state for a long time, so that bacteria and mold are easy to breed, and peculiar smell is easy to appear. When mopping the floor, not only can a better cleaning effect not be achieved, but also bacteria are easy to infect, which is not beneficial to human health.

The conventional antibacterial mop almost performs antibacterial treatment on the surface of chemical fiber, so that the mop has an antibacterial function. However, the chemical fiber cannot absorb water inside, so that the antibacterial property only stays on the surface of the fiber, the antibacterial effect is very limited, and after the corpse of bacteria is covered on the surface of the fiber, the subsequent bacteria cannot be well killed.

Patent application publication No. CN104790055A discloses a method for preparing viscose fiber containing sarcandra glabra extract, which has good bacteriostatic activity against Staphylococcus aureus, Escherichia coli and Candida albicans, but how to make sarcandra glabra extract into directly usable products.
