Background

With the acceleration of life rhythm, the increase of working pressure and the increasing severity of environmental problems, various infectious diseases prevail, which brings serious threat to the health of people and cuts off the spread of the infectious diseases, which is an effective way to solve the problem. At present, various infectious diseases are transmitted through air or contact, and the contact is a main channel of disease infection. In order to avoid the transmission of germs by a contact mode, disposable gloves are used in the aspects of medical treatment, medicine, sanitary protection and the like. Medical gloves are one of a plurality of disposable gloves, and generally can be disinfected before leaving a factory, but a certain time is usually needed from the glove leaving the factory to the use of a doctor, so that how to effectively perform antibacterial treatment on the gloves and prolong the antibacterial time of the gloves is a technical problem which is continuously explored in the field.

The existing medical gloves are mainly made of materials such as latex, silica gel, PVC plastic and the like, the materials have poor comprehensive performance, are easy to adhere to the epidermis of a hand when being worn, have large friction force and inconvenient use, contain more toxic and harmful substances and are easy to cause skin allergic reaction. In addition, because the material of the glove is the nutrient component of bacteria, the glove is easy to cause the breeding and the multiplication of bacteria or microorganisms, and increases the risk of infection diseases of doctors and patients. In order to solve the problem, a certain amount of antibacterial substances or components are generally added into a glove matrix in the prior art, but the substances are poor in compatibility with the glove matrix material, easy to dissolve, limited in antibacterial time-effect, or weak in antibacterial ability, and cannot effectively inhibit various pathogens. Some antibacterial substances have high toxicity and potential harm to human bodies.
