Example Embodiment
[0042] The first embodiment is a mask disclosed in the present invention, refer to figure 1 , Including a mask body 1 and a pair of ear straps 2 fixed on both sides of the mask body 1.
[0043] Reference figure 1 , figure 2 The mask body 1 includes an inner non-woven fabric layer 11, a filter layer 12, and an outer non-woven fabric layer 13 arranged in sequence. The filter layer 12 is a melt blown cloth layer. The side of the inner non-woven fabric layer 11 away from the filter layer 12 is the skin facing surface, and the side of the outer non-woven fabric layer 13 away from the filter layer 12 is the skin facing surface.
[0044] Reference figure 2 , image 3 The upper edge and the lower edge of the inner non-woven fabric layer 11 are respectively formed with an upper extending edge 111 and a lower extending edge 112. The upper extension edge 111 and the lower extension edge 112 are respectively folded to be integrated with the upper edge and the lower edge of the outer non-wov...
Example Embodiment
[0049] The second embodiment, a processing technology of a mask, used to produce the mask disclosed in the first embodiment, refer to Figure 1-3 , Including the following steps:
[0050] S0. First, electret treatment is performed on the filter layer 12;
[0051] S1. The inner non-woven fabric layer 11, the filter layer 12 and the outer non-woven fabric layer 13 are sequentially stacked from bottom to top to form a semi-finished product, and the semi-finished product is folded in the width direction by a sheeting machine to form four pleats;
[0052] S2. Hot press the edges on both sides of the folded semi-finished product, so that the inner non-woven fabric layer 11, the filter layer 12 and the outer non-woven fabric layer 13 are welded together;
[0053] S3. Two ends of the ear band 2 are respectively hot-pressed with the upper and lower edges of the outer non-woven fabric layer 13, so that the ear band 2 and the outer non-woven fabric are welded together;
[0054] S4. Place the nose...
