Abstract

The invention discloses a preparation method of a functional mask fabric, and belongs to the technical field of filter materials. The preparation method of a mask specifically comprises the following steps of 1) preparing a surface layer lotus leaf-like fabric; 2) preparing a core layer electrospun nanofiber composite membrane; 3) preparing an inner skin contact layer fabric; and 4) combining the mask fabrics. The surface layer of the mask adopts a lotus leaf tissue imitating design, and has the functions of stain resistance, easy washing and easy care; the core layer utilizes an electrospun nanofiber microporous membrane technology and has the advantages of high barrier efficiency, durability, effectiveness and the like; the surface layer fabric and the inner layer fabric are sewn, and a zipper is mounted on one side, so that the core layer electrospun nanofiber composite membrane is convenient to replace, and cyclic utilization is realized; and according to the mask fabric, the BFE filtering efficiency reaches 95% or above, the PFE filtering efficiency reaches 95% or above, and the breathing resistance is smaller than 200 Pa.

Description

Technical field [0001] The present invention belongs to the technical field of filter material, and more particularly to a functional mask fabric and a preparation method thereof. Background technique [0002] In today's world, white pollution and microma problems are getting more serious, and all countries around the world have issued relevant laws to prohibit or limit the use of non-degradable plastics. At present, the demand for medical protective supplies such as masks and protective clothing has increased dramatically, but its waste of waste has further exacerbated environmental burden, and therefore, a biodegradable functional mask is urgently needsed. [0003] Polylactic acid fiber (PLA) is a new type of renewable, complete biodegradable polymer new material, which can be broken down into carbon dioxide and water in soil or sea water, and it will not dissipate toxic gas when burning. Will not cause environmental pollution. Therefore, polylactic acid is used as an alternati...
