摘要： The present invention relates to an absorbent core (1) for an absorbent article, comprising absorbent material and a continuous channel (4) substantially free of said absorbent material. Said channel (4) comprises at least (i) one longitudinally extending central section (41) coincident with the longitudinal center line (LCL), (ii) four longitudinally extending lateral sections (42), (iii) four diagonally extending diagonal sections (43), and (iv) one transversally extending ending section (44, 44′). A continuous channel made of at least these essential channel sections provides fast absorption, good liquid distribution throughout the entire core, improved fit and comfort and minimizes the risk of leakage.

摘要： An absorbent article comprising: a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core positioned between said topsheet and backsheet, wherein the absorbent core comprises an absorbent material, said absorbent material comprising cellulose fibers and/or superabsorbent polymers, and wherein said absorbent material is contained within at least one core wrap substrate enclosing said absorbent material therein, wherein the absorbent core further comprises an intermediate layer positioned between a top layer of said core wrap and a bottom layer of said core wrap such that said absorbent material is disposed between said top layer and said intermediate layer and/or between said bottom layer and said intermediate layer, and wherein said top layer, said bottom layer, and said intermediate layer are joined together to form one or more channel forming areas substantially free of said absorbent material.
