Detailed Description

The present invention will be described in further detail with reference to the following embodiments and accompanying drawings.

Example 1

Fig. 1 to 2 schematically show a non-woven mask with good air permeability according to an embodiment of the present invention.

As shown in fig. 1 to 2, the non-woven mask with good air permeability includes a mask body 1. The mask body 1 comprises a first non-woven fabric layer 11, a third non-woven fabric layer 13, a second non-woven fabric layer 12 and a fourth non-woven fabric layer 15, wherein the first non-woven fabric layer 11, the third non-woven fabric layer 13 and the second non-woven fabric layer 12 are sequentially arranged from outside to inside, the fourth non-woven fabric layer 15 is arranged between the second non-woven fabric layer 12 and the third non-woven fabric layer 13, the fourth non-woven fabric layer 15 is a double-layer hot air non-woven fabric, one layer of the fourth non-woven fabric layer 15 is a plane layer 151, the other layer is a protruding layer 152, the plane layer 151 is close to the second non-woven fabric layer 12.

Therefore, the utility model discloses a non-woven fabrics gauze mask has changed the structure of traditional gauze mask, has add a fourth non-woven fabrics layer 15 that has bilayer structure between inlayer non-woven fabrics and middle non-woven fabrics, and fourth non-woven fabrics layer 15's protruding layer 152 can support third non-woven fabrics layer 13 for the inboard space increase in third non-woven fabrics layer 13, and then the air permeability of effectual reinforcing gauze mask improves the travelling comfort of wearing.

The bump layer 152 is composed of a plurality of bumps 152 a. The protrusions 152a may be hemispherical, pyramidal, or otherwise shaped. The protrusion 152a of the present embodiment has a hemispherical shape.

The fourth nonwoven fabric layer 15 of the present embodiment is a bacteriostatic nonwoven fabric, and the bacteriostatic master batch can be added to the fourth nonwoven fabric layer 15 to achieve a permanent bacteriostatic effect. Therefore, the mask has certain antibacterial and antibacterial effects.

The first nonwoven fabric layer 11 is a water-repellent nonwoven fabric. Therefore, the mask has a certain waterproof effect.

The third nonwoven fabric layer 13 is an electrostatic electret meltblown nonwoven fabric. Therefore, the melt-blown non-woven fabric subjected to electret finishing has lasting static electricity, and can trap fine dust by means of the static effect, so that the melt-blown non-woven fabric has the advantages of high filtering efficiency, low filtering resistance and the like.

The mask body 1 of the present embodiment is suitable for manufacturing various types of masks. Fig. 2 is a schematic view showing the structure of one type of mask to which the mask body 1 is applied.

As shown in fig. 2, the second nonwoven fabric layer 12 is provided with folding edges 121 on both sides in the length direction, and the folding edges 121 are connected to the first nonwoven fabric layer 11 by hot melt adhesion or ultrasonic welding. The mask body 1 further comprises a nose bridge strip 14, and the arrangement direction of the nose bridge strip 14 is consistent with the length direction of the first non-woven fabric layer 11. The nose bridge 14 is disposed between the folded edge 121 of the second nonwoven fabric layer 12 and the first nonwoven fabric layer 11. Therefore, the nose bridge strip 14 can clamp the nose bridge, and the stability of the whole mask is further improved.

Example 2

Fig. 3 to 4 schematically show a non-woven fabric mask according to another embodiment of the present invention.

As shown in fig. 3 to 4, the nonwoven mask of the present embodiment has substantially the same structure as that of embodiment 1, and the difference is that: the non-woven mask of the present embodiment further includes an elastic fixing portion 2.

As shown in fig. 3 to 4, the elastic fixing portion 2 of the present embodiment is provided on the side of the second nonwoven fabric layer 12 away from the third nonwoven fabric layer 13. Both ends of the elastic fixing portion 2 are connected to the second nonwoven fabric layer 12 by hot melt adhesion or ultrasonic welding, and the middle portion is separated from the second nonwoven fabric layer 12. The elastic fixing portion 2 is disposed on the second non-woven fabric layer 12 for wearing, and when not in use, the elastic fixing portion 2 covers the middle portion of the second non-woven fabric layer 12 to protect the inner side of the mask to a certain degree.

The fixing part is provided with an opening 21, and the opening 21 is matched with the ears of a wearer. When the elastic fixing part is worn, the elastic fixing part 2 is only required to be sleeved in the head part, and then the two ears are exposed out of the opening 21, so that the use is convenient. As shown in fig. 4, the number of the holes 21 in the present embodiment is two, and the two holes 21 are respectively provided at both ends of the elastic fixing portion 2.
