Embodiment 1

[0036] Embodiment one is basically as attached Figure 1 to Figure 4 As shown, the ultra-thin non-inductive core body includes top non-woven fabric 1, absorber 2, upper non-woven fabric 3, middle layer 4 and lower non-woven fabric 5 arranged in sequence from top to bottom, top non-woven fabric 1 A cavity is formed between the upper layer of non-woven fabric, and the top layer of non-woven fabric 1 is processed with a cutting line 6 near the back section of the core (where the back section of the core is attached to the buttocks of the human body), and the cutting line 6 is formed after being opened. The placement opening contains a detachable absorber 2 in the cavity, and the absorber 2 is provided with a polymer water-absorbing material, and the absorber 2 can be put into the cavity through the placement opening.

[0037] The top non-woven fabric 1 is bonded to the edge of the upper non-woven fabric 3, the upper non-woven fabric 3, the middle layer 4 and the lower non-woven f...

Embodiment 2

[0047] Embodiment two is basically as attached Figure 5 As shown, embodiment two has made the following improvements on the basis of embodiment one: an elastic block 12 is bonded between the top non-woven fabric 1 and the upper layer non-woven fabric (changing the absorbent cotton 9 in embodiment one into elastic block 12), the elastic block 12 adopts a water-absorbing sponge, wherein a water-repellent layer 13 is bonded to the top surface of the water-absorbing sponge and the side away from the middle of the core body. Water-permeable spun-bonded non-woven fabric; the height of the elastic block 12 in a free state is higher than that of the absorber 2, the number of the elastic block 12 is two, and the elastic block 12 and the absorber 2 are located on both sides of the diversion groove 8, A groove is formed between the two elastic blocks 12 .

[0048] The specific implementation process is as follows:

[0049] A groove is formed between the two elastic blocks 12. After th...

Abstract

The invention relates to the technical field of sanitary products, and particularly discloses an ultrathin hardly-felt core. The ultrathin hardly-felt core comprises an upper non-woven fabric and a lower non-woven fabric which are arranged up and down, the lower non-woven fabric is used for being tightly attached to a bottom membrane of a sanitary absorption product, a wavy middle layer permeableto water is fixedly connected between the upper non-woven fabric and the lower non-woven fabric, a plurality of containing pits are formed between the middle layer and the upper non-woven fabric and between the middle layer and the lower non-woven fabric, the adjacent containing pits do not communicate, and the containing pits are filled with a macromolecular water absorption material. The schemeis used for solving the problems that in the prior art, as an absorption core is too thick, a sanitary absorption product has poor breathability and the comfort is reduced.

Description

technical field [0001] The invention relates to the technical field of sanitary products, in particular to an ultra-thin non-inductive core body. Background technique [0002] Existing hygienic absorbent products include sanitary napkins, paper diapers and pull-up pants. These hygienic products include a base film, an absorbent core and a skin-friendly surface non-woven fabric. The surface non-woven fabric is in contact with human skin and can penetrate The liquid discharged from the human body (menstrual blood, urine or other excreta), the liquid discharged from the human body enters the absorbent core and is absorbed by the absorbent core. The bottom film can not only effectively prevent the liquid absorbed by the absorbent core from leaking out, but also To achieve a breathable effect. [0003] The existing absorbent core consists of upper and lower layers of non-woven fabrics and polymer water-absorbing materials in the middle of the non-woven fabrics. The polymer water...
