Paper diaper capable of being dry and comfortable and fast to absorb

Abstract

The utility model discloses a dry and comfortable paper diaper fast in absorption, relates to the technical field of paper diapers, and aims to solve the technical problems that an existing paper diaper is slow in urine absorption, and sometimes the phenomena that the surface of the paper diaper is wet and a middle layer shifts occur after the middle layer of the paper diaper absorbs too much urine and macromolecules absorb water to expand. Comprising an anti-side-leakage permeable layer, a diversion layer, a core layer, a middle layer, a bottom layer and a front waist tape. Due to the fact that the close-fitting surface layer of the paper diaper adopts the combination that the middle is hydrophilic and the two sides are water-repellent, the infiltrating phenomenon of the close-fitting surface layer is avoided, the fluffy cotton has the advantages of being fluffy, high in compression resilience, porous and the like, and the dust-free paper has unique physical performance, is high in elasticity, soft, good in hand feeling and draping feeling, extremely high in water absorption and good in water retention performance. And the upper and lower parts of the fluffy cotton are uniformly distributed with macromolecules, so that the high-molecular fabric has the high-quality characteristics of softness, fluffiness, dryness, quickness in absorption, no breakage and the like.

Description

Technical Field

[0001] The utility model relates to the technical field of diapers, and more specifically to a diaper that is dry and fast absorbing. Background Art

[0002] With the development of the times and the improvement of living standards, people are paying more and more attention to improving the quality of life. Diapers are becoming daily necessities for infants and people with incontinence because of their convenience in use and replacement, good ventilation and moisture absorption.

[0003] Since the middle layer of diapers is made of wood pulp, cotton and polymers, the soft touch and urine absorption speed of diapers are closely related to the middle layer. When the middle layer of diapers absorbs too much urine, the polymer will expand after absorbing water, and sometimes the surface of the diaper will become wet and the middle layer will shift. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet actual needs, and provide a diaper that is dry and absorbs quickly, so as to solve the technical problems that the current diapers absorb urine slowly, and the middle layer of the diaper will swell after absorbing too much urine, and sometimes the surface of the diaper will become wet and the middle layer will shift after the polymer absorbs water.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a dry and fast-absorbing diaper, comprising a side leakage prevention layer, a guide layer, a core layer, an intermediate layer, a bottom layer, a front waist tape, a magic buckle, an elastic rubber band, a hydrophilic non-woven fabric, toilet paper, dust-free paper and fluffy cotton; the side leakage prevention layer is separated into a close-fitting surface layer and a cotton core layer by a hydrophilic non-woven fabric, and the cotton core layer is arranged in the close-fitting surface layer; the close-fitting surface layer is formed by hot-melt adhesive with the hydrophilic non-woven fabric and the side leakage prevention layer to form a water-repellent structure on both sides, and the guide layer is arranged at the bottom of the close-fitting surface layer; the cotton core layer is composited by the core layer, the intermediate layer and toilet paper, and the core layer is composited by the hydrophilic non-woven fabric, the fluffy cotton and the dust-free paper in sequence by hot-melt adhesive, and the hydrophilic non-woven fabric, the fluffy cotton and the dust-free paper are The composite parts are all uniformly distributed with polymers; the bottom layer is arranged on the bottom inner wall of the anti-side leakage and penetration layer by hot melt adhesive, the front waist tape is arranged on the bottom of the anti-side leakage and penetration layer, the magic buckle is arranged on the top of the anti-side leakage and penetration layer, and the elastic rubber band is arranged inside the anti-side leakage and penetration layer. The utility model solves the problem of wetting of the close-fitting surface layer because the diaper adopts a combination of hydrophilic middle and water-repellent on both sides. The fluffy cotton has the characteristics of fluffy, high compression resilience and porosity, while the dust-free paper has unique physical properties, such as high elasticity, softness, excellent hand feel and drape, extremely high water absorption and good water retention performance, and because the fluffy cotton has uniformly distributed polymers on the top and bottom, the utility model has the high-quality characteristics of softness, fluffyness, dryness, fast absorption and no layer breaks.

[0006] Preferably, the hydrophilic non-woven fabric is compounded to the top inner wall of the side leakage prevention layer by hot melt adhesive. When the baby discharges urine, the diaper has a urine concentrated area. The urine concentrated area usually causes the water potential in the absorption core of the urine concentrated area to be higher than other ordinary absorption core areas. Therefore, due to the porous structure and hydrophilicity of the core layer, the urine in the concentrated area can be quickly drained to the remaining middle layers.

[0007] Preferably, the toilet paper is laminated to the bottom inner wall of the side leakage prevention layer by hot melt adhesive.

[0008] Preferably, the middle layer is laminated to the top of the toilet paper by hot melt adhesive.

[0009] Preferably, the core layer is compounded on top of the middle layer by hot melt adhesive.

[0010] Preferably, the fluffy cotton is compounded on the inner wall of the hydrophilic non-woven fabric by hot melt adhesive, and the dust-free paper is compounded on one side of the hydrophilic non-woven fabric by hot melt adhesive.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model solves the problem of infiltration of the close-fitting surface layer of the diaper by adopting a combination of hydrophilic middle and water-repellent on both sides. The fluffy cotton has the characteristics of fluffy, high compression resilience, and porosity, while the dust-free paper has unique physical properties, such as high elasticity, softness, excellent hand feel and drape, extremely high water absorption and good water retention performance. In addition, since the fluffy cotton has evenly distributed polymers on the top and bottom, the utility model has the high-quality characteristics of softness, fluffyness, dryness, fast absorption, and no layering.

[0013] 2. When the baby urinates, there is a concentrated urine area on the diaper. The water potential in the absorbent core of the concentrated urine area is usually higher than that in other common absorbent core areas. Therefore, due to the porous structure and hydrophilicity of the core layer, the urine in the concentrated area can be quickly drained to the remaining middle layers.

[0020] Working principle: This embodiment provides a diaper that is dry and absorbs quickly. When in use, the diaper is first put on the baby and then fits the front waist tape 6 with the magic buckle 7 so that the diaper is put on the baby. When the baby urinates, the urine is absorbed from the hydrophilic non-woven fabric 9 into the core layer 3, and the urine is completely absorbed by the fluffy cotton 12. At the same time, the guide layer 2 can prevent the urine from flowing out of the diaper. When the baby urinates, there is a urine concentrated area on the diaper. In this urine concentrated area, the water potential in the absorption core of the urine concentrated area is usually higher than that of other ordinary absorption core areas. Therefore, due to the porous structure and hydrophilicity of the core layer 3, the urine in the concentrated area can be quickly drained to the remaining middle layers 4.
