Embodiment 1

[0025] Embodiment one is basically as attached Figure 1 to Figure 3 Shown:

[0026] An absorbent core structure, comprising a core body 1. The core body 1 includes a surface layer 2, an absorption layer and a bottom layer 3 from top to bottom. The layer comprises an upper absorbent layer 4 and a lower absorbent layer 5, the upper absorbent layer 4 is coated with a first super absorbent resin, and the lower absorbent layer 5 is coated with a second super absorbent resin, the water absorption of the first super absorbent resin is better than that of the second absorbent layer. High water-absorbent resin, the water retention of the second super-absorbent resin is better than that of the first super-absorbent resin, and the bottom layer 3 adopts dust-free paper with good diffusivity. The thickness of the core body 1 gradually decreases from the center to both ends along the length direction, the surface layer 2 is provided with two symmetrically arranged grooves 6 along the leng...

Embodiment 2

[0029] Embodiment two is basically as attached Figure 4 , Figure 5 Shown:

[0030] The difference between this embodiment and Embodiment 1 is that two elliptical guide holes 8 are opened in the middle of the absorbent layer, an upper groove is opened at the bottom of the upper absorbent layer, and an upper groove is opened at the top of the lower absorbent layer. The lower groove, the upper groove and the lower groove are combined to form a diversion chamber 9, and the diversion chambers 9 are distributed along the length direction of the core body 1 at intervals, and a flow channel 10 is connected between the liquid diversion channel 7 and part of the diversion chamber 9 .

[0031] After the urine reaches the middle of the surface layer 2, it seeps down to the middle absorbent layer, and the diversion holes 8 can divert the urine, so that the urine can quickly diffuse into the diversion chambers 9 on both sides, thereby promoting the absorption of the upper absorbent laye...

Abstract

The invention relates to the technical field of hygienic products and discloses an absorption type core structure. The absorption type core structure comprises a core body, wherein the core body comprises a surface layer, an absorption layer and a bottom layer, wherein the surface layer is provided with a slot in the length direction of the core body; and the thickness of the core body is gradually reduced from the center to the two ends along the length direction. By utilizing the slot which is formed along the length direction of the core body, urine can be guided along the length directionof the core body through the slot after dropping onto a paper diaper, the urine in the middle of the core body can quickly spread to the two ends of the core body, and the whole absorption length of the core body is increased, so that the absorption efficiency of the core body can be improved, and the absorption efficiency of the core body is prevented from being influenced due to the fact that urine is concentrated in the middle of the core body.

Description

technical field [0001] The invention relates to the technical field of sanitary products, in particular to an absorbent core structure. Background technique [0002] At present, the use of diapers is becoming more and more widespread, not only for infants and young children, but also for adults with diseases or people who cannot defecate independently. For diapers, the core key technology is the core structure, which directly determines the performance of diapers in many aspects, such as: absorbency, air permeability, stability, etc. [0003] After the existing diapers are used, the diffusion length of urine generally does not exceed 60% of the core length of the product, resulting in low absorption efficiency of the diapers, which cannot achieve the dry effect of the surface layer in contact with the skin, causing inconvenience to the user. comfortability. Contents of the invention [0004] The purpose of the present invention is to provide an absorbent core structure t...
