Description

Technical Field

[0001] The utility model relates to the technical field of disposable absorption, in particular to a dry diaper with a diversion groove. Background Art

[0002] The diaper mainly comprises a three-dimensional edge, a liquid-permeable surface layer, a diversion layer, an absorption layer, spandex, and an impermeable bottom layer which are stacked in sequence from top to bottom. The diversion grooves on the inner surface layer of the diaper are generally shallow grooves pressed during the lamination of the surface layer, the absorption layer, and the bottom layer, with poor or no diversion effect, so that urine will be concentrated and absorbed in the middle of the absorption layer, that is, the crotch of the diaper. When the urine absorption reaches a certain amount, leakage will still occur even if a three-dimensional edge is provided.

[0003] To solve the above problems, this case is thus produced. Content of the Utility Model

[0004] Therefore, in view of the above problems, the utility model provides a dry diaper with a diversion groove.

[0005] To solve the above technical problems, the solution adopted by the utility model is: a dry diaper with a diversion groove, comprising a three-dimensional edge, a liquid-permeable surface layer, a diversion layer, an absorption layer, spandex, and an impermeable bottom layer which are stacked in sequence from top to bottom. The absorption layer includes two upper absorbents, a hydrophilic separator layer, a lower absorbent, and a hydrophilic coating layer. The hydrophilic separator layer is arranged on the upper surface of the lower absorbent. The two upper absorbents are arranged on both sides of the upper surface of the hydrophilic separator layer. A diversion groove is formed between the two upper absorbents. At least one thick water-conducting fiber is arranged in the diversion groove and is fixedly arranged on the hydrophilic separator layer. The diversion layer is arranged on the upper surface of the upper absorbent and above the diversion groove. The hydrophilic coating layer is arranged to cover both sides of the upper surface of the diversion layer from the lower surface of the lower absorbent.

[0006] Further improvement is: the upper absorbent includes a first absorbent core and a first hydrophilic coating outer layer, and the first hydrophilic coating outer layer completely wraps the first absorbent core.

[0007] Further improvement is: the first absorbent core is a high molecular polyester fiber absorbent core.

[0008] Further improvement is: the first hydrophilic coating outer layer is airlaid paper or toilet paper or spunlace fabric.

[0009] Further improvement is: the lower absorbent includes a second absorbent core and a second hydrophilic coating outer layer, and the second hydrophilic coating outer layer completely wraps the second absorbent core.

[0010] Further improvement is: the second absorbent core is a high molecular wood pulp absorbent core.

[0011] Further improvement: The second hydrophilic coating outer layer is dust-free paper, toilet paper or spunlace fabric.

[0012] Further improvement: The hydrophilic coating layer is spunlace non-woven fabric, dust-free paper, toilet paper or spunbond non-woven fabric.

[0013] Further improvement: The water-conducting thick fiber is ES fiber, and the denier of the ES fiber is 2-12D.

[0014] Further improvement: The hydrophilic isolation layer is a spunlace non-woven fabric layer.

[0015] By adopting the foregoing technical solutions, the beneficial effects of the present utility model are:

[0016] In this case, the absorption layer adopts an upper and lower double-layer structure. The upper layer is provided with two upper absorbers at intervals to form a diversion groove. The depth of the diversion groove is determined by the thickness of the first absorber. The diversion groove strengthens the diversion effect of the diaper in the front-back direction and is also beneficial to preventing urine from leaking laterally. The water-conducting thick fiber arranged in the diversion groove further strengthens the diversion effect of the diaper. The diversion layer is arranged on the upper surface of the upper absorber above the diversion groove, leveling the surface of the absorption layer, making the surface layer of the diaper more beautiful and not affecting the urine diversion effect.

[0017] The hydrophilic isolation layer and the water-conducting thick fiber are first glued and then combined with the upper absorber and the lower absorber, which is convenient for production and manufacturing.

[0018] The hydrophilic coating layer wraps the upper absorber, the lower absorber and the diversion layer into one body, so that the absorption layer and the diversion layer can be processed and manufactured first, and then combined with the liquid-permeable surface layer and the liquid-impermeable bottom layer.

[0019] Further beneficial effects are: The upper absorber is composed of a high-molecular polyester fiber absorption core and a first hydrophilic coating layer, and the lower absorber is combined with a high-molecular wood pulp absorption core and a second hydrophilic coating layer. The water absorption of the high-molecular polyester fiber absorption core is inferior to that of the high-molecular wood pulp absorption core, so that the urine is absorbed by the lower absorber after passing through the diversion groove, which is beneficial to keeping the upper surface of the absorption layer dry and improving the wearing comfort of the diaper; the upper absorber, the hydrophilic isolation layer and the water-conducting thick fiber can effectively prevent the high-molecular wood pulp absorption core from caking or breaking, and improve the overall use feeling of the diaper.
