Preparation method of disposable mask

Abstract

The invention relates to the field of masks, provides a preparation method of a disposable mask, and overcomes the defects that a mask preparation method in the prior art is relatively low in production speed and relatively high in required machine table cost, and the preparation method comprises the following preparation steps: 1) preparation of a mask main body; (2) spandex filament compounding,(3) edge folding treatment, (4) third folding treatment, (5) end sealing, (6) compounding of elastic flat ear hooks and the mask main body, (7) hot pressing and (8) slitting.

Description

technical field [0001] The invention relates to the field of masks, in particular to a method for preparing a disposable mask. Background technique [0002] Masks are a common sanitary protection product. Wearing a mask has a good protective effect when respiratory infectious diseases are prevalent and when working in dusty and other polluted environments. Masks generally include masks with two-layer structure, masks with three-layer structure and activated carbon masks. Common disposable masks are generally composed of surface non-woven fabrics, bottom non-woven fabrics, filter paper or filter cloth, ear loops, and nose bridges, which are generally metal wires or plastic strips. , When wearing it, pinch the nose bridge strip to fix it on the nose bridge to seal the mask. The ear hooks are usually two thin ropes. Disposable masks with this structure, because of the thinner ear loops, have greater pressure on the ears, and the ears feel more uncomfortable after wearing for ...

AI Technical Summary

Problems solved by technology

In the traditional disposable mask preparation process, the ear loops need to be welded with a spot welding machine after the main body of the mask is finished, which requires an independent connection process, the production speed is slow, and an additional spot welding machine is required, which is costly; secondly, the mask When the middle part of the main body is three-folded, a specific wrinkling equipment is usually used, usually a crumpling roller. This kind of equipment is needed to press out the wrinkled area, and the required equipment cost is relatively high.
