Technical Field

The invention relates to the technical field of sanitary products, in particular to an absorbent article.

Background

Conventionally known absorbent articles include sanitary napkins, incontinence garments, pants-type sanitary napkins, diapers, and the like. The functional core structure of the absorbent article mainly comprises three parts: a surface layer, an absorber, a bottom layer; a top sheet having liquid permeability and being in direct contact with the skin of a user for providing a comfortable and dry feeling when in contact with the body while allowing liquid to freely pass through into the absorbent body of the lower layer; the absorber is used for absorbing and keeping human excretory fluid, can promote the rapid penetration of the fluid and effectively prevent the rewet; the bottom layer can keep liquid gathered in the absorbent body and can not cause leakage.

Disclosure of Invention

The surface layer with a plane structure such as cloth or non-woven fabric and the absorber with a sheet structure have the plane structure, so that the flow guiding performance in all directions is the same or similar, even though some surface layers and absorbers are provided with holes, grooves, indentations, concave-convex longitudinal flow guiding devices, the flow guiding in the transverse direction is inevitable, and the transverse width of the absorber and the surface layer used by people is far smaller than that in the longitudinal direction, so that the side leakage phenomenon that liquid transversely spreads out of the boundary is easy to occur. It should be avoided that it has a cross-directional flow path, so that a surface layer and an absorbent body having a planar structure are not the most desirable configurations. The plane structure is changed into a combination of a plurality of lines or strips which are arranged in order, because the lines are mutually lack of transverse connection, the liquid transversely spreads and lacks channels, the spreading speed is relatively reduced, and relatively larger space is reserved between the lines, so that more liquid can be favorably locked in the lines. Because the lines are lack of mutual entanglement and confinement, the whole absorber is softer and more comfortable, the bonding performance to the human body is better, and the back leakage and the side leakage are better prevented. In addition, the structure can be made into disposable articles, and can also be processed into reusable articles, when the structure is used as a reusable product, the washing of the interior of the structure is easier to realize, the problem of internal residue is avoided, the airing speed is high, and the airing device is safer and more sanitary. Therefore, a plurality of threads or strips are orderly stacked or arranged together, and can be used as an absorption body or a surface layer.

The present invention is directed to provide an absorbent article, in which the absorbent is composed of a plurality of lines or strips, and the lines or strips are orderly stacked or arranged. The absorbent body thus provided has both the air-permeable comfort of the top sheet, the good flow conductivity of the flow-guiding layer, and the desirable liquid-retaining property of the absorbent body.

Optionally, its bottom can have waterproof function, also can not have waterproof function, the line or strip is according to vertical setting, can reduce horizontal drainage, effectively prevents the edge leakage, the line or strip can be pricked into several bundles and use, also can align to grid and pile up, fixes the absorber through near the both ends at the line or strip and connects on the bottom, and the middle part of line has better degree of freedom like this, conveniently carries out deformation according to the human body.

Optionally, in order to better prevent back leakage, a back absorption body is provided, the back absorption body is arranged at the back of the absorption body and is composed of threads or strips which are arranged transversely but not limited transversely, and in order to prevent liquid from overflowing from the front, a front absorption body is also optionally arranged, and the front absorption body is arranged at the front of the absorption body and is composed of threads or strips which are arranged transversely but not limited transversely.

The absorbent article can be processed into a disposable product, and the materials of the absorber and the bottom layer can also be made of reusable materials, so that the aim of recycling can be fulfilled, and the cleaning and airing effects are better.

In addition, the invention provides an absorbent article, which comprises an absorbent body and a bottom layer, wherein the absorbent body is formed by orderly stacking or arranging a plurality of lines or strips, the lines or strips have a hollow structure, and the high-water-absorption polymer is arranged in the hollow structure. So that the liquid can be rapidly diffused along the lines and simultaneously absorbed and maintained by the internal high-water-absorption polymer, the high-water-absorption polymer can be uniformly utilized, and the absorption capacity and efficiency of the liquid are increased.

In addition, the invention provides an absorbent article, which comprises a surface layer, a bottom layer and an absorbent body arranged between the surface layer and the bottom layer, wherein the absorbent body is formed by orderly stacking or arranging a plurality of lines or strips, and the high water-absorbent polymers are dispersed in the lines or strips, so that the absorbent body can quickly and uniformly absorb more liquid, and the soft air permeability of the absorbent body is ensured.

In addition, the present invention provides an absorbent article having a top sheet adjacent to the human body composed of a plurality of lines or stripes which are orderly stacked or arranged. Because the relatively large gaps are formed among the lines, the liquid infiltration speed is very high, the flow guide effect along the lines is good, and the surface layer of the planar structure in the prior art is replaced, so that the side leakage can be better prevented.

In order to provide a surface layer with a good flow guide effect and an ultrathin comfortable article with sufficient absorption capacity, the bottom layer is provided with a plurality of cavities, the cavities are internally provided with the super absorbent polymer, the super absorbent polymer is uniformly and reasonably distributed by the cavities, and the light and thin absorbent article is guaranteed to be suitable under the cooperation of the surface layer with good flow guide and permeation effects.

In addition, the invention also provides an absorbent article, wherein a middle convex part is arranged at the middle part close to the human body side, and the middle convex part consists of a plurality of threads or strips which are longitudinally arranged. Absorbent articles are often difficult to conform to the body structure, especially when the wearer is lying on his or her back or side, and they are not flexible to move about and make the appropriate adjustments, where liquids can easily run along the groin or other parts of the body, resulting in back leakage or side leakage. After the middle convex part is arranged, the absorption capacity of the middle area is increased, so that the fitting performance is better, each relatively independent long line is more beneficial to deformation of different positions in the femoral groove, the deformation is not entangled by transverse fibers, the fitting performance is better, the air permeability is good, foreign body sensation is avoided, the use is comfortable, the absorption performance and the flow guide performance are better, the manufacturing process is simple, and the production and the processing are easier.

Optionally, one end of the middle convex part is a fixed end, the other end of the middle convex part is a free end, and the lines or the strips of the free end are fixedly connected together through a connecting piece. Thus, the free end can be pulled up and attached to the groin when in use, can better follow the free movement of the body of a wearer, and can change the shape along with the body shape (the shape of the crotch part), and is attached and ventilated. This makes it difficult for the absorbent article to form a gap with the body (crotch portion) of the wearer, and therefore, side leakage and back leakage of the discharged liquid can be more reliably prevented.

In order to improve comfort and ensure the use effect, the thickness of the thread ranges from 0.005mm to 1mm, and the width of the strip ranges from 1mm to 15 mm. The order of the lines is too thin and can be reduced, the lines are easy to be entangled into knots, the air permeability and the flexibility are affected, the lines are too thick or too wide, the comfort and the diversion effect can be reduced, and therefore the thickness and the width range of the lines can be reasonably set. The experimental result shows that the effect is better when the hair thickness is close to the thickness of human hair.

The thread or strip can be made of natural fiber (such as animal and plant fiber such as cotton, hemp, silk, wool and the like) or artificial fiber or artificial-natural combined fiber; the thread or strip can be made of single fiber or a combination of a plurality of fibers; the line or strip in the invention refers to a structure body with the length being larger than the maximum cross section width, such as a general line shape, a strip shape, a belt shape and the like.

Embodiments of the invention provide the following advantages: the air-permeable floor has the advantages of better flow conductivity, soft and comfortable use, good air permeability, simple structure and convenient processing and production, and can well prevent back leakage and side leakage.
