Description

Comfortable breathable paper diaper

Technical Field

The utility model relates to the technical field of daily necessities, in particular to a comfortable breathable paper diaper.

Background

The paper diaper is a common disposable sanitary product and becomes a necessary product for nursing infants due to the strong water absorption function of the paper diaper. The paper diaper on the market at present mainly comprises a surface layer, a flow guide layer, an absorption core layer, a leakage-proof bottom layer and an elastic three-dimensional protection structure. The materials of the surface layer of the paper diaper on the market are mostly non-woven fabrics with strong air permeability, so that moisture and hot air of urine can be discharged out of the diaper body in time; the diversion layer is usually made of special non-woven materials, can quickly and uniformly absorb liquid, and prevent or reduce urine from seeping back; the material of the absorption core layer mainly comprises pure wood pulp (fluff pulp) and super absorbent resin (SAP), and can quickly absorb and store urine; the leakproof bottom layer is mainly composed of PE film, has water impermeability, and can prevent water in the absorbent core layer from seeping out of the pants body.

Patent CN109984888A discloses an infant diaper that gas permeability is good, be provided with the non-woven fabrics basement membrane of prevention infiltration gas, all non-woven fabrics of diaper are whole to be constituteed by the fibrous layer of high ventilative, do not have plastic film, row that can be quick dehumidify, heat, improved the present poor problem of plastic film gas permeability for the diaper, but do not distinguish the design to the physiological characteristics of boy baby and girl baby, and the partial low-usage that absorbs water before the panty-shape diapers, cause the raw and other materials extravagant. Patent CN102090953B discloses a diaper, which has at least one branch at the front end of the absorbent core layer, and the branches can be combined and folded to form a three-dimensional structure. The front ends of the covering layer and the base fabric can also be folded to form a three-dimensional structure. The three-dimensional structure at the front end of the paper diaper can provide space for the scrotum of a boy baby, so that the heat dissipation condition of the scrotum is improved, the normal development of the reproductive system of the boy baby is facilitated, only the paper diaper with the three-dimensional structure at the rear end can be used by the girl baby, but the comfort of wearing the baby is reduced by folding the three-dimensional structure, the use method is complex, and the use of the baby in the outgoing process is inconvenient.

Due to the physiological structure characteristics of the female baby, most of urine is accumulated in the rear two thirds of the water absorbing part of the paper diaper when the paper diaper is used, the amount of the urine in the front one third of the water absorbing part is little or almost zero, particularly, the phenomenon is more obvious when the female baby sleeps at night, and the discomfort of the baby is caused by excessive urine in the rear part. Most paper diaper on the market are general for men and women baby at present, less respectively to design man and women baby's physiological characteristics, and most formula structures as an organic whole of water absorption portion, thickness are unanimous, do not set up the subregion, consequently lead to paper diaper water absorption portion front third's utilization ratio very low, not only cause the waste of paper diaper raw and other materials and use the travelling comfort poor.
