Embodiment 1

[0054] The present embodiment adopts the following preparation method to prepare masks:

[0055] 1) PP fibers are spunbonded to prepare PP non-woven fabrics, and carbon black conductive fibers are woven into the fabrics at certain intervals in the warp and weft directions by weaving to obtain a protective layer;

[0056] 2) Using PP fiber to cooperate with Lyocell fiber and chitosan fiber to prepare the fabric substrate of the filter layer by needle punching;

[0057] 3) take the PTFE microporous membrane and stretch, and combine with the fabric base material in a laminated manner to obtain a filter layer;

[0058] 4) PP fibers are spunbonded to prepare PP non-woven fabrics to obtain a skin-friendly layer;

[0059] 5) Combine the protective layer prepared in step 1), the filter layer prepared in steps 2) and 3), and the skin-friendly layer prepared in step 4) by lamination to obtain a mask body.

[0060] In the above scheme, the mass proportion of each component is shown in ...

Embodiment 2

[0063] In the present embodiment, the preparation method of mouth mask is the same as in Example 1, and the mass ratio of each constituent is as shown in the following table:

Abstract

The invention discloses a mask, which comprises a mask body. The mask body includes a protective layer, a filter layer and a skin-friendly layer arranged sequentially from outside to inside. The filter layer includes a microporous membrane and a fabric base material. The fabric base material It is made of synthetic fibers, Lyocell fibers, chitosan fibers and / or seaweed fibers; the synthetic fibers include one or more of PP fibers, PET fibers and PA fibers. In the mask of the present invention, the filter layer is a composite material of a microporous membrane and a fabric base material, so that the filter mechanism of the mask is transformed into a physical surface filter of a microporous membrane from the deep-level filtration of the existing electret treatment technology, and the filter layer is filtered while breathing. , the backwashing of the filter layer is completed by the exhalation process, the filtering effect is better, and the purpose of repeated use can be achieved. Through the design of the fabric substrate components, the antibacterial properties of Lyocell fiber and chitosan fiber / seaweed fiber are used. The antibacterial and deodorizing effect of the mask has been realized.

Description

technical field [0001] The invention belongs to the technical field of respiratory protection equipment, and in particular relates to a mask and a preparation method thereof. Background technique [0002] The development of effective protective technologies and protective materials is particularly important. As a respiratory protection product, masks can filter the air inhaled into the lungs to a certain extent. Therefore, they are a powerful guarantee for epidemic prevention, a basic condition for orderly resumption of work and production, and a psychological safety barrier for the public. In the case of a serious imbalance between the production and demand of disposable non-woven masks, the development of reusable masks is particularly important. [0003] The existing disposable non-woven mask can store electric charge for a long time by electret processing the middle meltblown layer, and then can use the principle of electrostatic capture to adsorb dust, droplets, etc., ...
