Description

Disposable sanitary article

Technical Field

The utility model relates to a disposable hygienic product field especially relates to a disposable hygienic product.

Background

The structures of disposable sanitary products such as paper diapers and sanitary napkins are well known, and generally comprise a liquid-permeable surface layer, a liquid-impermeable bottom layer and an absorber arranged between the liquid-permeable surface layer and the liquid-impermeable bottom layer, wherein the absorber is formed by wrapping upper wet strength paper and lower sanitary paper, a flow guide layer non-woven fabric is arranged between the liquid-permeable surface layer and the absorber for increasing the diffusion speed of liquid in the disposable sanitary products, but the liquid-permeable surface layer of the existing disposable sanitary products cannot be well attached to the skin of a human body, the time for the liquid to permeate into the liquid-permeable surface layer is long, the liquid cannot be rapidly absorbed into the flow guide layer and then diffused when the disposable sanitary products are worn, the anti-reverse-permeation effect is poor, the disposable sanitary products are uncomfortable to wear, and the quality of the disposable sanitary products is.

The prior patent No. 201520327284.5 provides an improved diaper having reasonable design of diversion structure on the diversion layer, smooth liquid diversion and diffusion, improved diversion characteristics, and effective improvement of dry and comfortable comfort of the diaper, which is sequentially provided with a skin-friendly surface layer, a diversion layer, a water absorbing layer and a waterproof and breathable bottom layer from top to bottom, wherein the skin-friendly surface layer is provided with a first penetration hole communicated with the diversion layer, the diversion layer is provided with a warp compaction groove and a weft compaction groove which are interwoven together to form a grid, an included angle alpha is formed between the warp compaction groove and the weft compaction groove, the included angle alpha ranges from 15 degrees to 75 degrees, the width of the warp compaction groove is larger than that of the weft compaction groove, the width of the weft compaction groove is gradually reduced in the direction extending from the front end to the rear end of the diaper, and the warp compaction groove and the weft compaction groove are both provided with a second penetration hole communicated with the water absorbing layer, it realizes liquid infiltration and diffusion effect through setting up water conservancy diversion layer structure, but the absorber is improper with water conservancy diversion structural design for the infiltration speed of liquid is still not fast enough, and has the reverse osmosis phenomenon, reduces the dry and comfortable comfort level of health absorption articles for use.

SUMMERY OF THE UTILITY MODEL

Therefore, in order to solve the above problems, the present invention provides a disposable hygienic product capable of making liquid quickly seep downward.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a disposable hygienic product, is horizontal including absorbing the body, and the definition is along the width extending direction who absorbs the body, and is vertical along its length extending direction, it includes from the top down liquid-permeable surface course, absorption sandwich layer and the liquid-tight bottom that the stromatolite set up in proper order to absorb the body, it includes the wrapping film that absorbs the core and be used for the protection to absorb the core, it is formed by the bonding of upper absorption core and lower floor absorption core to absorb the core, upper absorption core and lower floor absorption core are made by fluffy cotton, evenly fill in fluffy clearance of fluffy cotton has the polymer water-absorbing resin granule, the fluffy clearance of upper absorption core is greater than the fluffy clearance of lower floor absorption core.

Further improved, the upper surface and the lower surface of the upper layer absorption core body are both provided with wavy concave-convex structures.
