Description

Design of punched non-woven fabric used as flow guide layer in disposable hygienic product

Technical Field

The invention relates to the technical field of personal hygiene products, in particular to an internal circulation absorption paper diaper with a surface layer, a middle hydrophilic part and two sides for repelling water.

Background

The main structure of most products such as baby diapers, baby toddler pants, adult diapers and the like which circulate in the market all adopts a surface layer, a flow guide layer, an absorption layer and a bottom layer, wherein the flow guide layer mainly plays a role in transversely and longitudinally dredging liquid falling from the surface layer in the products, so that the rapid infiltration of the liquid is ensured, the residual surface pollution and the skin irritation are prevented, the core body of the absorption layer can more comprehensively absorb urine, the effective absorption area is enlarged, the effective absorption capacity of a single-piece product is improved in such a way, the flow guide layer of the current market products adopts hot air non-woven fabrics with high gram weight and long and thick fibers, a net-shaped structure is formed by the transverse and longitudinal crossing of the long and thick fibers, when the liquid contacts the flow guide layer with the structure, the liquid can naturally flow along the fiber path, the local urine of consumers can be effectively diffused, the residual time and the residual area of the surface layer liquid are reduced, finally improve the absorption properties of products such as panty-shape diapers, but the high gram of weight that the market all adopted at present, long thick fiber's hot-blast non-woven fabrics is because of the problem of its high gram of weight and hot-blast material, its material structure is comparatively fluffy, the fibre direction is clear visible, though the mesh of drainage diffusion has been reached, can be simultaneously after most liquid conduction drainage, can remain a small amount of liquid all the time on the fibre and can't be effectively absorbed by the absorbed layer, when the buttock produced certain pressure to product surfaces such as panty-shape diapers when single consumer used, this part liquid will return the infiltration out fast through surface course material, cause the not dry and comfortable nature of surface course, still can produce certain irritability to skin when liquid is the urine, finally lead to the buttockss red, for this reason, we propose the interior circulation absorption panty-shape diapers that hydrophilic both sides are refused water in.

Disclosure of Invention

The invention aims to provide an internal circulation absorption paper diaper with a hydrophilic surface layer and two water repellent sides, which solves the problems of high gram weight and long and thick fiber hot air non-woven fabrics adopted in the current market in the background technology, namely, the hot air non-woven fabrics are fluffy due to high gram weight and hot air material, the material structure of the hot air non-woven fabrics is relatively fluffy, the fiber guide direction is clear, the purpose of drainage and diffusion is achieved, a small amount of liquid can be remained on the fiber and can not be effectively absorbed by an absorption layer after most of liquid is conducted and drained, when a single consumer uses the diaper, the hip generates certain pressure on the surfaces of the paper diaper and other products, the liquid can quickly return and seep out through the surface layer material, the surface layer is not dry and refreshing, when the liquid is urine, certain irritation can be generated on the skin, and finally the problem of red hip is caused.

In order to achieve the purpose, the invention provides the following technical scheme: an inner circulation absorption paper diaper with water repellent on two sides in the middle of a surface layer comprises an absorption layer and a bottom layer, wherein the top edge of the bottom layer is adhered to the bottom edge of the absorption layer, the top of the absorption layer is provided with a surface layer, the bottom edge of the surface layer is adhered to the top edge of the absorption layer, the surface layer comprises a middle water repellent section, a first through hole is uniformly and vertically formed in a body of the middle water repellent section, a first groove is uniformly and vertically formed in the body of the middle water repellent section, the first through hole and the first groove are arranged in a staggered mode, an inner hydrophilic section is arranged at the top of the middle water repellent section, a second through hole is uniformly and vertically formed in the body of the inner hydrophilic section, a second groove is uniformly and vertically formed in the body of the inner hydrophilic section, the second through hole and the second groove are arranged in a staggered mode, an outer hydrophilic section is arranged at the bottom of the middle water repellent section, and, the outer hydrophilic section body is uniformly and vertically provided with a third groove, the third through holes and the third grooves are arranged in a staggered mode, liquid passing holes are uniformly formed between the left side wall and the right side wall of the inner cavity of the first groove and the adjacent first through holes, the upper end and the lower end of the first groove correspond to the second through holes and the third through holes respectively, and the inner hydrophilic section and the outer hydrophilic section are the same as the middle water repellent section in structure.

Preferably, the widths of the middle water-repellent section, the inner hydrophilic section and the outer hydrophilic section are all 30-80 mm.

Preferably, the surface layer is a non-woven fabric surface layer.

Preferably, the widths of the first groove, the second groove and the third groove are all 1-3mm, and the depths of the first groove, the second groove and the third groove are all 1-4 mm.

Preferably, the aperture of each of the first through hole, the second through hole and the third through hole is 0.5-2 mm.

Compared with the prior art, the invention has the beneficial effects that: according to the scheme, the hydrophilic and water-repellent segmented arrangement adjustment is carried out on the surface layer, the arrangement of punching and groove alternation and crossing on the surface layer can effectively increase the absorption diffusion speed by 10% -30%, the gel blocking risk is reduced, the diffusion is accelerated, the urine cannot be excessively remained on the surface of the paper diaper, and particularly, when the urine is produced for many times, the probability of the phenomenon of untimely urine leakage, dryness and even red buttocks absorption can be greatly reduced.
