Problems solved by technology

The existing absorbent body with good performance has a large thickness, poor air permeability, and insufficient softness; due to the large thickness and insufficient softness, the fit with the human body is not good, and it is easy to cause back leakage when lying on the back, and the liquid leaks. The diffusion effect is not ideal. When the liquid diffuses to the left and right sides of the absorbent body, due to the small width of the absorbent body, the liquid is easy to overflow out of the absorbent body, resulting in side leakage of absorbent articles
[0005] In addition, absorbent articles generally cannot be reused, and the waste of resources also brings environmental pollution. Most of the existing reusable absorbent sanitary products have absorbent bodies that are sewn into one fabric, and the thickness of the absorbent body is relatively large and not soft enough. , and the interior is difficult to clean and cannot be effectively dried and sterilized, there are safety hazards in use, and the long drying time is also a major worry for users
[0006] In addition, in order to prevent side leakage and rear leakage, some existing absorbent articles often have a protrusion in the middle part to fit the shape of the genitals to achieve the effect of preventing surge, accelerating absorption and diversion, but this protrusion will increase The production process is difficult, it is difficult to follow the human body to produce ideal deformation, the effect is not ideal, and the comfort is low
Therefore, there is room for improvement in existing raised structures

no. 1 approach

[0033] Such as figure 1 As shown in figure a in the middle, it is an example in which the absorber 2 is composed of a plurality of wires 21 stacked in order. Such as figure 1 As shown in figure b in the middle, it is an example in which the absorber 2 is formed by orderly arrangement of a plurality of strips 22 .

[0034] Such as figure 2As shown, in the absorbent article 00, the absorbent body 2 is formed by orderly stacking a plurality of threads 21, and the threads 21 are divided into several thread bundles 211, and the threads 21 are arranged in the longitudinal direction, passing through 212 and 213 near the two ends of the thread Fastening joins the absorbent body 2 to the backsheet 3 . The middle part of the line 21 has sufficient degrees of freedom, which is convenient to deform according to the human body, and has a better fit.

[0035] Such as image 3 As shown, in order to better prevent back leakage, a rear absorbent body 214 is arranged at the rear of the ab...

no. 2 approach

[0038] Such as Figure 4 and 5 As shown, the absorbent article 00 includes an absorbent body 2 and a bottom layer 3. The absorbent body 2 is formed by a plurality of threads 21 arranged in an orderly manner. The threads 21 have a hollow structure, and a superabsorbent polymer 4 is arranged in the hollow 210 . The liquid can be rapidly diffused along the line 21 while being absorbed and retained by the superabsorbent polymer 4 inside, so that the superabsorbent polymer 4 can be utilized efficiently and uniformly.

no. 3 approach

[0040] Such as Figure 6 As shown, the exploded diagram of the absorbent article 00 includes a surface layer 1, a bottom layer 3, and an absorbent body 2 arranged between the surface layer 1 and the bottom layer 3. The absorbent body 2 is formed by stacking a plurality of threads 21 in an orderly manner. The superabsorbent polymer 4 is scattered in the thread 21, so that the absorbent body 2 can quickly and evenly absorb more liquid, and ensure the softness and breathability of the absorbent body.

[0041] Fourth embodiment.

[0042] Such as Figure 7 , 8 As shown, in the absorbent article 00, the surface layer 1 close to the human body is formed by orderly arrangement of a plurality of threads 21 (the lines can also be stacked in an orderly manner if the density of the surface layer needs to be increased). The surface layer 1 can replace or cooperate with the surface layer in the prior art absorbent articles, and has better use experience and effect.

Abstract

The invention relates to the technical field of health products, in particular to an absorbent article. The absorbent article is characterized in that an absorbent body or a surface layer is formed bypiling or arranging multiple threads or strips in order, and the absorbent article has better flow guide performance, is soft and comfortable to use, has good breathability, can well prevent backwardleakage and later leakage and is simple in structure and convenient to produce and process; and an added convex part is simple in structure, easy to product, good in use effect, free of foreign bodysensation and high in comfort.

Description

technical field [0001] The invention relates to the technical field of hygiene articles, in particular to an absorbent article. Background technique [0002] Conventionally known absorbent articles include sanitary napkins, incontinence garments, underpants-type sanitary napkins, diapers, and the like. The functional core structure of absorbent articles mainly includes three parts: the surface layer, the absorbent body, and the bottom layer; the surface layer, which is liquid-permeable, is in direct contact with the user's skin and is used to provide a comfortable and dry feeling when in contact with the body, while allowing liquid to be free Through, enter the absorbent body of the lower layer; the absorbent body is used to absorb and retain human excretion fluid, which can promote the rapid penetration of liquid and effectively prevent back seepage; the bottom layer can keep the liquid accumulated in the absorbent body without causing leakage. [0003] The surface layer o...
