[0030] In an embodiment of the utility model, the bottom of the non-woven fabric upper layer 1 is provided with a plurality of semicircular protrusions 10 extending downwardly from the non-woven fabric upper layer 1. By providing the semicircular protrusions 10, the bonding area of ​​the bottom of the non-woven fabric upper layer 1 is increased, thereby improving the bonding firmness of the bottom of the non-woven fabric upper layer 1.

[0031] In the embodiment of the utility model, the surface of the semicircular protrusion 10 is provided with arcuate stripes 11. By providing the arcuate stripes 11, the bonding firmness between the surface of the semicircular protrusion 10 and the adhesive is improved.
