In order to achieve the above purpose, the utility model adopts the following technical scheme: the dry and comfortable absorber comprises a surface layer, a covering layer and a core body which are sequentially arranged, wherein the core body comprises a hydrophilic layer, a water guide SAP layer, a fluffy layer, a water absorption SAP layer and dust-free paper which are sequentially arranged.

The principle and the advantages of the scheme are as follows: during the practical application, the surface course contacts skin, as outermost protection, the overburden is as the interlayer, prevents that SAP in the core from getting into the surface course, avoids rubbing damage skin to cause red and swollen, and the core is as the main part that absorbs liquid and keep dry and comfortable. The hydrophilic layer improves hydroscopicity and liquid diffusivity, leads liquid to the water guide SAP layer, and the water guide SAP layer absorbs liquid and further water conservancy diversion to the lower floor, and fluffy layer provides the expansion space after the absorption for SAP, and the SAP layer that absorbs water absorbs the liquid of water conservancy diversion completely, and dustless paper prevents that SAP from dropping to can play certain diffusion to the liquid that permeates the bottom, make liquid can be thoroughly absorbed. The absorbent is used for the paper diaper, can fully and thoroughly absorb urine, effectively avoids the problems of red swelling, inflammation and diaper rash caused by liquid reverse osmosis, incomplete absorption and the like, can keep dry and comfortable for a long time, and enables a baby to wear the paper diaper more comfortably.

Preferably, as a modification, the surface layer is a nonwoven fabric with uniformly distributed holes. Therefore, the surface layer is skin-friendly, breathable and good in water permeability, and is more beneficial to keeping dry and comfortable.

Preferably, as a refinement, the cover layer is a nonwoven. Therefore, the covering layer has excellent air permeability, and can effectively block SAP particles and prevent the SAP particles from entering the surface layer to damage the skin.

Preferably, as an improvement, the hydrophilic layer is a hydrophilic regenerated fiber non-woven fabric, and the thickness of the hydrophilic layer is less than or equal to 1mm. Therefore, the super-hydrophilic regenerated fiber non-woven fabric can be adopted, the surface layer moisture is guided and diffused by utilizing the hydrophilic gradient difference, the moisture is guided into the core body, and the reverse osmosis of the moisture to the surface layer is reduced.

Preferably, as a refinement, the water-conducting SAP layer has an average particle size of SAP particles of 400. This allows the water-directing SAP layer to efficiently absorb the liquid and direct the liquid toward the lower layer.

Preferably, as a refinement, the SAP particle average particle size of the water-absorbing SAP layer is 350. The SAP particles of the water-absorbing SAP layer thus absorb liquid sufficiently to avoid a certain degree of liquid rewet.

Preferably, as an improvement, the fluffy layer is fluffy non-woven fabric with the thickness of 6 mm. Thus, the fluff layer provides sufficient space for the expanded SAP particles after water absorption, and can fix the expanded SAP particles to avoid running and bunching.

Preferably, as an improvement, the water-conducting SAP layer is more water-conducting than the water-absorbing SAP layer, and the water-absorbing SAP layer is more water-absorbing than the water-conducting SAP layer. Therefore, the liquid can flow to the lower layer as much as possible, and the liquid can be fully and thoroughly absorbed.

Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: the dust-free paper comprises a surface layer 1, a covering layer 2, a hydrophilic layer 3, a water guide SAP layer 4, a fluffy layer 5, a water absorption SAP layer 6 and dust-free paper 7.

The embodiment is basically as shown in the attached figure 1: a dry and comfortable absorbent is in a cuboid shape and comprises a surface layer 1, a covering layer 2 and a core body which are sequentially arranged, wherein the surface layer 1 is a non-woven fabric with holes uniformly distributed, and the covering layer 2 is a non-woven fabric. The core body comprises a hydrophilic layer 3, a water guide SAP layer 4, a fluffy layer 5, a water absorption SAP layer 6 and dust-free paper 7 which are arranged in sequence.

The hydrophilic layer 3 is a hydrophilic regenerated fiber non-woven fabric, the thickness of the hydrophilic layer 3 is less than or equal to 1mm, the average particle size of SAP particles of the water guide SAP layer 4 is 400, the fluffy layer 5 is a fluffy non-woven fabric with the thickness of 6mm, and the average particle size of SAP particles of the water absorption SAP layer 6 is 350. The water-conducting SAP layer 4 has a higher water-conductivity than the water-absorbing SAP layer 6, and the water-absorbing SAP layer 6 has a higher water-absorbing property than the water-conducting SAP layer 4.

The specific implementation process is as follows: when the paper diaper is used, the surface layer 1 is in contact with the skin and absorbs water and is breathable, and the covering layer 2 is used as an interlayer to prevent SAP particles from entering the surface layer 1 and avoid damaging the skin. Super hydrophilic regenerated fiber non-woven fabrics in the five-layer structure of the core body are used as a hydrophilic layer 3, play a role in diversion and diffusion, and can utilize the difference of hydrophilic gradient to guide and convey the moisture of the surface layer 1 into the core body. SAP (Super Absorbent Polymer) has a high water absorption function of absorbing water several hundred to several thousand times heavier than itself and is excellent in water retention property, and it is difficult to separate water even when pressure is applied when it swells into hydrogel upon water absorption. The double-layer SAP is adopted, the SAPs with different properties are adopted, and the particle size is adjusted, so that the liquid can be guided to the lower layer as much as possible by absorbing the liquid, and the full absorption of the liquid is ensured. The SAP swells after absorbing water, and the bulky layer 5 serves as a carrier of the SAP, is placed in the middle to provide a certain space, and fixes the SAP so that the SAP does not move and get tangled. The dust-free paper 7 at the lowest layer bears SAP from the bottom, prevents the SAP from falling off, plays a certain role in water diffusion and ensures the full and thorough absorption of liquid. The absorbent body of the scheme has excellent dryness and comfort, is helpful for infants to wear the absorbent body dry and comfortable, and reduces red buttocks.
