Background Art

The absorbent has the advantage of rapid absorption of liquids and is widely used in diapers, sanitary napkins and other fields. As the core part of the absorbent product, the performance of the absorbent chip is directly related to the user experience of the absorbent product.

The first generation of traditional absorbent cores uses a structure that is made by mixing wood pulp & SAP particles and then wrapping them with toilet paper/non-woven fabrics. With the continuous development of science and technology and the continuous improvement of the production technology of absorbent cores, the absorbent core has basically completed the transformation from the first generation of traditional absorbent cores to the second generation of composite absorbent cores. The second generation of absorbent cores uses dust-free paper, spunbond non-woven fabrics, SAP particles, spunlace non-woven fabrics, etc., which are bonded layer by layer with hot melt adhesives to solve the many performance problems of the first generation of absorbent cores, such as poor structural strength and easy fracture, poor diffusion and easy bulging, and being too thick, stuffy and airtight. However, due to the limitations of the performance of the existing second generation absorbent cores, the wearing comfort, leak-proofing, and breathable and dry performance of the existing absorbents still fail to meet people's high requirements.

DETAILED DESCRIPTION

The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

As shown in Fig. 1-5, an absorbent body with a breathable and dry 3D absorbent chip includes an upper layer 110, a lower layer 120 located below the upper layer 110, and an absorbent chip 200 located between the upper layer 110 and the lower layer 120; the absorbent chip 200 includes a SAP particle fixing layer 210, an upper covering layer 220, and a lower covering layer 230 located below the SAP particle fixing layer 210; the upper covering layer 220 includes an upper covering portion located above the SAP particle fixing layer 210, and a SAP particle distribution layer 240 is provided between the upper end of the SAP particle fixing layer 210 and the upper covering portion, and between the lower end of the SAP particle fixing layer 210 and the lower covering layer 230; the SAP particle distribution layer 240 forms a SAP particle aggregation layer. The SAP particle gathering area 241 is provided with a plurality of SAP units 243, and each side guide area 242 is surrounded by a plurality of SAP units 243, and the SAP units 243 include a plurality of water-absorbing particles; the SAP particle gathering area 241 includes two side sub-gathering areas 244 and a main gathering area 245 located between the two side sub-gathering areas 244; the two side guide areas 242 correspond to the two side sub-gathering areas 244 respectively, and each side guide area 242 is located between the corresponding side sub-gathering area 244 and the main gathering area 245; the thickness of the SAP units 243 arranged in sequence in the side sub-gathering areas 244 along the direction close to the corresponding side guide areas 242 is set in a decreasing manner.

The utility model provides an absorbent body with a breathable and dry 3D absorption chip. The absorption chip 200 is reasonably arranged so that when in use, both sides of the absorption chip 200 can be tilted and erected along the side guide area 242, and fit the crotch in a ︺ shape, thereby improving the wearing comfort, especially for infants and young children in the learning to walk stage and the free walking stage, and it is not easy to form an outward eight-shaped step; when the absorbent body is worn, the urine is quickly diffused to the front and rear ends along the side guide area 242, so as to improve the three-dimensional leakage prevention height in disguise, and prevent urine leakage caused by splashing when the infant and young child urinates, and at the same time, the thickness of the SAP units 243 arranged in sequence in the side sub-aggregation area 244 along the direction close to the corresponding side guide area 242 is set in a decreasing manner, so that the side sub-aggregation area 244 is farthest from the corresponding side guide area The thickness of the SAP units 243 arranged in sequence in the direction of zone 242 is the largest, so as to further reduce the risk of urine splashing and side leakage when the wearer urinates, thereby greatly enhancing the urine leakage prevention ability of the absorbent body; moreover, the side guide zone 242 of the absorbent chip 200 is not provided with SAP units 243, so as to improve its breathability, and because the SAP particle aggregation zone 241 with multiple SAP units 243 rapidly expands to form a convex area after absorbing urine, the side guide zone 242 relatively forms a concave area, which has a very intuitive and effective effect on isolating urine and loose stools, and at the same time, by forming a concave and convex layered area, the contact area between the buttocks skin and the absorbent body is greatly reduced, thereby significantly improving its breathability and dryness, greatly enhancing the dryness experience, and significantly reducing the chance of causing red buttocks.

A central diffusion zone 246 is also provided in the middle of the main gathering zone 245, and a plurality of SAP units 243 are provided on the periphery of the central diffusion zone 246. By adopting the above arrangement, the central diffusion zone 246 of the absorbent chip 200 is not provided with SAP units 243, so that its air permeability can be improved. Moreover, since the main gathering zone 245 with a plurality of SAP units 243 rapidly expands to form a convex area after absorbing urine, the central diffusion zone 246 forms a concave area, so that the contact area between the buttocks skin and the absorbent body can be further reduced, so as to further improve its air permeability and dryness performance.

Specifically, the thickness of the SAP units 243 of the main gathering area 245 is uniform. The extension track of the central diffusion area 246 is in a straight line.

Preferably, the extension track of the side guide area 242 is curved, so as to improve its guide effect.

The upper cover layer 220 has folded portions 221 formed on both left and right sides thereof, which are bonded to the lower end of the lower cover layer 230 through an adhesive layer.

As a preferred embodiment of the present invention, the distance d between two adjacent SAP units 243 in the length direction of the SAP particle fixing layer 210 is 1-5 mm. The distance e between two adjacent SAP units 243 in the width direction of the SAP particle fixing layer 210 is 1-5 mm. The width b of the central diffusion zone 246 is set to 10-30 mm, and the width c of the side guide zone 242 is set to 5-30 mm.

In this embodiment, the upper covering layer 220 can be made of dust-free paper, hydrophilic non-woven fabric, spunlace fabric, natural fiber fabric, etc. The upper covering layer 220 is bonded to the SAP particle fixing layer 210 through the upper adhesive layer, and the lower covering layer 230 is bonded to the SAP particle fixing layer 210 through the lower adhesive layer.

Preferably, the upper layer 110 includes a skin-friendly surface layer 111. The left and right sides of the skin-friendly surface layer 111 are covered with a three-dimensional side leakage prevention enclosure system 112. The three-dimensional side leakage prevention enclosure system 112 is formed by bonding the side leakage prevention non-woven fabric 2 and the three-dimensional elastic band 12 by gluing or ultrasonic/thermal bonding.

Of course, in addition to this, the upper layer 110 may also adopt other structures, but adopting the above structure for the upper layer 110 is the best implementation of the present invention, which can improve its anti-leakage effect.

The lower layer 120 includes a leakproof film 121, a urine display strip 122 disposed above the leakproof film 121, and a skin-friendly bottom layer 123 disposed below the leakproof film 121; a leg elastic band is disposed between the leakproof film 121 and the skin-friendly bottom layer 123, a front waist patch 125 is disposed on the skin-friendly bottom layer 123, and ear patches 126 for adhering to the front waist patch 125 are disposed on both the left and right sides of the leakproof film 121. Specifically, Velcro is disposed on the ear patches 126, so that the Velcro of the ear patches 126 and the fluffy fibers in the front waist patch 125 are adhered and connected, so as to provide the adhesive force required to fix the diaper when the absorbent is applied to the diaper.

The lower layer 120 further includes an elastic waist non-woven fabric 127 disposed between the absorbent core 200 and the anti-leakage film 121 , and an elastic spandex yarn 128 wrapped in the elastic waist non-woven fabric 127 .

Of course, in addition to this, the lower layer 120 may also adopt other structures, but adopting the above structure for the lower layer 120 is the best implementation of the present invention and is convenient for manufacturing.

The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
