Problems solved by technology

[0002] Diapers include a bottom film, a liquid-absorbent core, and a water-permeable layer. The water-permeable layer is the part that contacts the absorbent liquid for the first time. The water-permeable layer allows the absorbent liquid to pass through to the liquid-absorbent core to absorb the absorbent liquid. Under unfavorable conditions, the water-permeable layer is more likely to produce more free absorbent liquid, and the liquid leakage will increase due to the failure to reach the liquid-absorbent core. In the case of a large amount of free liquid, it will affect the comfort of the user.

Embodiment Construction

[0029] refer to Figure 1 to Figure 7 , a multi-convex type water-permeable layer, including a surface layer 1, a middle layer 2, and a bottom layer 3, and the surface layer 1, the middle layer 2, and the bottom layer 3 are all made of non-woven fabrics. The surface layer 1 includes a first plane 11, and first arcuate surfaces 12 arranged at intervals in the first plane 11, and the intermediate layer 2 includes a second plane 21, and second arcuate surfaces arranged at intervals in the second plane 21. 22. The bottom layer 3 includes a third plane 31 and a third arcuate surface 32 arranged at intervals in the third plane 31. The first arcuate surface 12 and the second plane 21 conflict with each other, and the second arcuate surface 22 and the The third planes 31 conflict with each other. By laminating multiple layers, the first arc surface 12, the second arc surface 22, and the third arc surface 32 can guide the flow, and the first arc surface 12, the second arc surface 22, ...

Abstract

The invention discloses a multi-convex point type water-permeable layer and a manufacturing method thereof. The first arcuate surface and the second plane are in conflict with each other, and the second arcuate surface and the third plane are in conflict with each other. The first arc surface, the second arc surface, and the third arc surface can conduct flow diversion through multi-layer lamination, and the first arc surface, the second arc surface, and the third arc surface make the liquid contact area large during the diversion process , which is more conducive to liquid diversion. The multi-convex-point water-permeable layer improves fluid transport, guides liquid flow, and improves user comfort.

Description

technical field [0001] The invention relates to a multi-convex type water-permeable layer and a manufacturing method thereof. Background technique [0002] Diapers include a bottom film, a liquid-absorbent core, and a water-permeable layer. The water-permeable layer is the part that contacts the absorbent liquid for the first time. The water-permeable layer allows the absorbent liquid to pass through to the liquid-absorbent core to absorb the absorbent liquid. Under unfavorable conditions, the water-permeable layer is more likely to produce more free absorbent liquid, which will increase the leakage of liquid due to the failure to reach the liquid-absorbent core. In the case of a large amount of free liquid, it will affect the comfort of the user. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a multi-convex type water-permeable layer and a manufacturing method thereof. [0004] The technical solution adop...
