Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The utility model relates to a combined type core panty-shape diapers. For example, the combined core paper diaper comprises a combined bottom layer, a core and a surface layer, wherein the combined bottom layer comprises a non-woven bottom layer and a PE film arranged in the middle of the surface of the non-woven bottom layer, and side edge areas exposed outside the PE film are respectively formed on two opposite sides of the non-woven bottom layer. For example, the nonwoven fabric bottom layer is provided with nonwoven fabric pieces on opposite sides of the front waist portion thereof to form a front waist portion, the nonwoven fabric pieces are covered on the side edge regions and the edges thereof are extended to cover the PE film, and the core is disposed on the composite bottom layer. For example, the core body comprises toilet paper, a main cotton core, a central cotton core and a surface cotton core, the main cotton core is arranged on the toilet paper, a central groove is formed in the center of the main cotton core, the central cotton core is arranged in the central groove, and the moisture absorption performance of the central cotton core is greater than that of the main cotton core. For example, the toilet paper is wrapped outside the main cotton core, the surface layer cotton core covers the toilet paper, and the surface layer is laid on the composite bottom layer so as to clamp the core body between the composite bottom layer and the surface layer.

Referring to fig. 1 to 4, a composite diaper with a core comprises a composite bottom layer 10, a core 20 and a surface layer, wherein the composite bottom layer 10 comprises a nonwoven fabric bottom layer 11 and a PE film 12 disposed on the middle portion of the surface of the nonwoven fabric bottom layer 11, opposite sides of the nonwoven fabric bottom layer 11 are respectively formed with side edge regions 115 exposed outside the PE film 12, opposite sides of the front waist portion of the nonwoven fabric bottom layer 11 are respectively provided with a nonwoven fabric piece 116 to form a front waist fastening portion 15, the nonwoven fabric pieces 116 cover the side edge regions 115 and extend to cover the PE film 12, the core 20 is disposed on the composite bottom layer 10, the core 20 comprises a toilet paper 21, a main cotton core 22, a central cotton core 23 and a surface cotton core, the main cotton core 22 is disposed on the toilet paper 21, the center of the main cotton core 22 is provided with a central groove 225, the central cotton core 23 is disposed in the central groove 225, the moisture absorption performance of the central cotton core 23 is greater than that of, the toilet paper 21 is wrapped outside the main cotton core 22, the surface cotton core is covered on the toilet paper 21, and the surface layer is laid on the composite bottom layer 10 so as to clamp the core body 20 between the composite bottom layer 10 and the surface layer.

Because the middle part of the paper diaper is provided with the multilayer composite core body 20, and the moisture absorption performance of the central cotton core 23 is stronger, the moisture absorption performance of the middle part of the paper diaper is stronger, and the urine is not easy to flow outwards. Since the nonwoven fabric pieces 116 are disposed on the opposite sides of the front waist portion of the nonwoven fabric bottom layer 11 to form the front waist portion 15, the nonwoven fabric pieces 116 cover the side edge regions 115 and the edges thereof extend to cover the PE film 12, the edges of the front waist portion 15 are made of nonwoven fabric, and the PE film 12 is retracted to the middle region, so that the air permeability of the nonwoven fabric can be improved by using the nonwoven fabric.

For example, to facilitate the placement of the central cotton core 23, the central channel 225 is an elliptical channel, and the central cotton core 23 has a superabsorbent resin (SAP) content that is 20 times the superabsorbent resin content of the main cotton core 22. The opposite sides of the main cotton core 22 are respectively provided with an arc waist line groove 228 in a concave way, and the middle part of the arc waist line groove 228 extends to the edge of the central groove 225. The major axis of the elliptical groove coincides with the central axis of the composite bottom layer 10. The toilet paper 21 comprises a combination part 211 and a first wrapping part 212 and a second wrapping part 213 which are convexly arranged at two opposite sides of the combination part 211, wherein the combination part 211 is positioned between the main cotton core 22 and the composite bottom layer 10, and the width of the first wrapping part 212 is equal to that of the second wrapping part 213. The first wrapping part 212 wraps the surface of the main cotton core 22 and covers the central cotton core 23, and the second wrapping part 213 wraps the surface of the first wrapping part 212. The surface cotton core has the same shape as the main cotton core 22, and is covered on the second wrapping part 213 and aligned with the main cotton core 22. The nonwoven fabric piece 116 is a square nonwoven fabric piece. The moisture absorption performance is improved by setting the content of the super absorbent resin of the central cotton core 23. The first and second wrapping portions 212 and 213 are disposed to wrap the object tightly.

For example, in order to prevent urine from leaking backwards, a water-repellent rear retaining wall is arranged on the surface layer, the front part of the water-repellent rear retaining wall is overlapped with the main cotton core 22, the rear part of the water-repellent rear retaining wall is positioned at the rear side of the main cotton core 22, a rear elastic rubber band is arranged on the front part of the water-repellent rear retaining wall, and the edge of the water-repellent rear retaining wall is fixedly bonded with the surface layer. The retaining wall can effectively prevent urine from leaking backwards, and particularly has better effect of preventing rear side leakage when being used for long-term bed rest. The water-repellent rear retaining wall can also use elastic water-repellent cloth with transverse stretching force, and the water-repellent rear retaining wall can also be made of common water-repellent fabric without transverse stretching force.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
