Three-dimensional breathable sheet and absorption product

Abstract

The invention discloses a three-dimensional breathable sheet and an absorption product. The absorption product comprises a surface layer and an absorption layer, wherein the surface layer is made of the three-dimensional breathable sheet. The three-dimensional breathable sheet comprises a surface sheet body and a bottom sheet body, wherein the surface sheet body is distributed in the middle of bottom sheet body, and the width of the surface sheet body is smaller than that of the bottom sheet body. The three-dimensional breathable sheet is provided with through holes penetrating the surface sheet body and the bottom sheet body and three-dimensional hollow protrusion areas formed by the surface sheet body and the bottom sheet body. The three-dimensional breathable sheet and the absorption product have the advantages that the surface sheet body is located in the middle of the absorption product, two sides, without the protrusion areas, of the bottom sheet body are adhered to the absorption layer of the absorption product, the liquid permeability and breathability of the surface layer are unaffected while the bonding strength between the surface layer and the absorption layer is increased favorably, the surface sheet body parts on two sides of the surface layer are omitted, the breathability of the absorption production is increased, and the production cost of the absorption product is lowered.

Description

technical field [0001] The invention relates to the field of non-woven fabrics, in particular to a three-dimensional breathable sheet with through holes and raised areas and an absorbent product. Background technique [0002] Usually, the surface materials of disposable sanitary products are mainly perforated film, non-woven fabric, perforated / embossed non-woven fabric, etc., especially perforated / embossed non-woven fabric has a three-dimensional structure due to its soft touch, which reduces the The area in contact with the skin, and the body fluid can seep out from the through hole, which accelerates the penetration speed of the body fluid, improves the dryness performance, and takes the lead in the market. There is a composite sheet in the existing patent application (the application number does not exist after checking, please confirm), which has an upper layer of fibers on a substantially flat lower layer of fiber sheets by three-dimensionally shaping the upper layer of...

AI Technical Summary

Problems solved by technology

There is a composite sheet in the existing patent application (the application number does not exist after checking, please confirm), which has an upper layer of fibers on a substantially flat lower layer of fiber sheets by three-dimensionally shaping the upper layer of fiber sheets There are a large number of convex parts formed by the sheet, and there are concave parts between the convex parts. The concave parts and the convex parts are alternately arranged on the composite sheet. When the high-viscosity excrement is soft, the soft stool is caught in the closed concave part surrounded by the convex part, so that it becomes difficult to cause lateral flow; However, the existence of adhesive points and the thickening of the non-woven fabric in the bonding area of ​​the concave part will hinder the penetration of excrement, especially high-viscosity feces and soft feces into the absorbent body, and the soft stool will stay on the bonding area of ​​the concave part , and the composite sheet increases the thickness of the sheet to a certain extent and reduces the air permeability. At the same time, after the non-woven fabric is embossed in a large area or embossed and perforated, the manufacturing cost of the surface material is increased to a certain extent.
