Abstract

DC60 (04/09/46) disclosed an absorbent product consisting of a backing (2), a permeable top layer (6), and an absorbent layer including hydrophobic material placed between the backing (2) and the top layer (6). A compression zone in which the absorbent layer is compressed and grooved, along with the top layer (6), is provided to extend continuously longitudinally at positions spaced transversely from the longitudinal centerline (Oy-Oy) of the absorbent product, thus defining the central absorbent zone between the compression zone and the external absorbent zone outside the compression zone. Within this central absorbent zone, a void-forming, low-density liquid-lead (5) layer is placed between the absorbent layer and the top layer (6) to allow the absorbent layer to be covered by the top layer (6). In this external absorbent zone, an absorbent product consisting of a backing (2) and a top layer (6) was disclosed. A permeable liquid layer (6) and an absorbent layer, including hydrophobic material, are placed between the backing layer (2) and the top layer (6). A compression layer, in which the absorbent layer is compressed and grooved, along with the top layer (6), is provided to extend continuously longitudinally at positions spaced transversely from the longitudinal centerline (Oy-Oy) of the absorbent product, thus defining the central absorbent region between the compression layer and the external absorbent region. Within this central absorbent region, a liquid layer (5), formed from interconnected voids and of lower density than the absorbent layer, is placed between the absorbent layer and the top layer (6) to cover the absorbent layer with the top layer (6) in this external absorbent region.

Claims (9)

1. Absorbent material products It consists of a backplate (2), a liquid-permeable top sheet (6), and a permeable layer that includes hydrophilic materials and is positioned. Between the backplate (2) and the aforementioned top plate (6), where the pressed part in which the absorbent layer is pressed and formed into a recess. Together with the top sheet (6) has been provided to provide Longitudinal continuous filing at a position that is transversely spaced from the longitudinal center line (Oy-Oy) of the absorbent product is defined as the material area Absorbed in the middle between the compression section and the extra absorbent area outside the compression area within the middle absorbed material area. Liquid (5) that has been formed from fibers That have been welded together In order to have a gap in it and to have a lower density, an absorbent layer has been placed between the absorbent and The top sheet (6), without overlapping with the compression section, allows the absorbent layer to be covered with the top sheet (6) in the absorbent area. Supplement it 2. Absorbent material as described in Clause 1, where the compression part is still extended. Further to meet each other and surround the area That was previously defined as the middle sorbent area where the fluid leading (5) is less than the sorbent area. Absorbs in the middle and does not overlap with the compression part. 3. Absorbent products as described in Clause 1, where the absorbent material is With the lower absorbent section (3) and the upper absorbent section (4) overlaid on the lower absorbent section (3), the upper absorbent section (4) has less area. The absorbent material below (3) and has a larger area than the Material absorbed in the middle Both the top absorbent section (4) and the lower absorbent section (3) are compressed and recessed together with the top sheet (6) in the compression section where the reinforced absorbent area has a The thick (12a) that is adjacent to The compression section, which contains both the lower absorbent (3) and the upper absorbent (4), and the thin (12b) outside the thickened area (12a) with the lower absorbent section. (3) present, but there is no upper absorbent part (4). 4. The absorbent product as described in claim 1, in which a number of fluid paths (15) have been formed in Medium permeable material area to pass through top sheet (6) and protrude into liquid leading (5). 5. Absorbent material as described in Clause 4 of which the chemical fiber As the top sheet (6) and the chemical fiber that make up the liquid layer (5), it is also fused together around the throughhole (15). 6. The absorbent product as described in claim 1, in which the leading dry state liquid (5) has a fiber density in the range 0.005 to 0.02 g / cm3. 7. The absorbent product as specified in claim 1, where pressure 980 Pa (10 g / sq cm) is applied in the wet state, the liquid layer (5) has a fiber density in Range 0.005 to 0.04 g / cm3. 8. The absorbent material as described in Clause 6, where the liquid (5) leading, is a non-woven, bonded type of fabric. Air-pass or air-permeable nonwoven fabric made of chemical fibers. 9. Absorbent material as described in Clause 8, where liquid leading (5) is formed by folding the fabric without Woven into a multi-layered structure
