Abstract

The invention relates to a composite stereoscopic sheet which is simple in structure, good in guiding effect, better in absorbing effect and more thorough in absorption. A plurality of projections and retainer wall type connecting parts for connecting the projections are evenly arranged on one surface. The retainer wall type connecting parts are larger than the projections in fiber density. The projections are regularly octagonal. One projection and the projection adjacent to the same overlap on one side of the regular octagon, and the overlapped side serves as one retainer wall type connecting part; four projections sequentially connected end to end enclose a second projection; the retainer wall type connecting parts are higher than the second projections in fiber density.

Description

technical field [0001] The invention relates to the field of production of disposable absorbent articles, in particular to a composite three-dimensional sheet with absorbing properties. Background technique [0002] Chinese Patent No.: 200880104490.2 discloses a shaped sheet, which is a sheet made of fibers, wherein one surface side has a plurality of convex parts and barrier wall-shaped connecting parts connecting the convex parts to each other, And the fiber density of the barrier wall-shaped connecting portion is higher than the fiber density of the convex portion. Wherein a kind of regular hexagonal shape embodiment is disclosed, such as figure 1 , figure 2 As shown, continuous convex portions 1' evenly distributed on the sheet are formed, and there are barrier wall-shaped connecting portions 2' between the convex portions 1. This method is applied in the field of disposable absorbent articles to form a good flow diversion, and also strengthens the absorption, and ma...
