According to the data of the example 3, the examples 7 and 8 in the table 2, the total bacterial colony number and the total fungal colony number of the example 3 are far lower than those of the examples 7 and 8, which shows that the single addition of the malva leaf extract or the purslane extract has little influence on the antibacterial property and the air permeability of the gloves, and the simultaneous addition of the malva leaf extract and the purslane extract improves the internal gaps among latex molecules in the latex gloves, so that the air permeability of the double-layer latex gloves is improved, the antibacterial property of the latex gloves is greatly improved, bacteria are not easy to breed in the gloves, and negative influence on human health is not easy to generate, and the breathable latex gloves capable of absorbing sweat and preventing moisture are obtained.

The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
