Abstract

The invention discloses a novel nanometer surgical mask filtering material and a manufacturing method thereof. The novel nanometer surgical mask filtering material comprises an outer layer, a middle layer and an inner layer, wherein the outer layer is a waterproof layer, the middle layer is a filtering layer, the inner layer is a moisture absorbing layer, and the filtering layer is formed by a nanometer film composite material. The novel nanometer surgical mask filtering material and the manufacturing method thereof have the advantages that the pore diameter of the middle of the filtering layer is smaller, the blocking efficiency is higher, the service life is long, and wearing is more comfortable.

Description

technical field [0001] The invention belongs to the technical field of masks, and in particular relates to a novel nano-mask filter material and a manufacturing method thereof. Background technique [0002] As people pay more and more attention to the atmospheric environment and indoor air quality, the environmental standards are becoming stricter and stricter. To achieve a high level of air cleanliness, the selected filter materials must have superior filter performance. In recent years, various high-efficiency air filter materials have made great progress. High-efficiency air filter materials have the characteristics of high filtration efficiency, small airflow resistance, high mechanical strength and good uniformity, and can meet the special functional requirements of air filter materials in specific industries. Existing gauze masks are made of gauze material with a large aperture, which can only intercept large particles in the air, but cannot block PM2.5 and the curren...
