Detailed Description

In order to make the technical problems solved, technical solutions adopted and technical effects achieved by the present invention clearer, the technical solutions of the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. Wherein the terms "first position" and "second position" are two different positions.

The present embodiment provides a grooved sanitary article which may be a sanitary napkin, panty liner, incontinence pad or the like, and is not limited to female users, but may also be elderly, small children, patients or the like. This embodiment will be described with reference to a sanitary napkin as an example. As shown in FIG. 1, the sanitary napkin may optionally comprise a surface nonwoven layer 1, an absorbent core layer 3 and a barrier backing layer 4 arranged in this order from top to bottom. The secretion such as menstrual blood or urine flows into the absorption core layer 3 from the surface nonwoven fabric layer 1, the absorption core layer 3 absorbs and stores the secretion, and the impermeable bottom film layer 4 plays a role in preventing the leakage of the secretion.

The surface non-woven fabric layer 1 is directly contacted with the skin, is preferably a hot air non-woven fabric, is soft in material, good in air permeability and capable of preventing secretion from seeping back. The barrier backing layer 4 is preferably a polyethylene film, a water impermeable material, and can retain excreta such as menstrual blood in the absorbent core layer 3. The bottom of the impermeable base film layer 4 is correspondingly provided with an adhesive part (not shown in the figure). When the sanitary towel is not used, the release paper is connected with the bonding part. When the sanitary towel is replaced, the release paper is torn off, and the anti-seepage basement membrane is adhered to the clothes through the adhering part.

Optionally, the sanitary napkin further comprises a flow-directing layer 2. The flow guiding layer 2 is arranged between the surface non-woven fabric layer 1 and the absorption core layer 3, so that secretion in the surface non-woven fabric layer 1 is quickly guided to the absorption core layer 3, dryness of the surface non-woven fabric layer 1 is guaranteed, and use comfort is improved.

In order to increase the absorption rate and the diffusion, a cutting process is performed on the absorbent core layer 3, as shown in fig. 2 and 3. In the case of a sanitary napkin for daily use, the absorbent core layer 3 is cut into a plurality of longitudinal cuts 31 and transverse cuts 32 as shown in FIG. 2, and the longitudinal cuts 31 and the transverse cuts 32 are arranged in a staggered manner without intersecting each other. The transverse cuts 32 are arranged in the middle, and the longitudinal cuts 31 are distributed around the transverse cuts 32, in the embodiment, the longitudinal cuts 31 and the transverse cuts 32 are arranged in a rectangular shape. The spacing between two longitudinally adjacent longitudinal cuts 31, between a longitudinal cut 31 and an adjacent transverse cut 32, and between adjacent transverse cuts 32 is equal to or greater than 5mm, the cutting depth of the longitudinal cuts 31 and the transverse cuts 32 is less than the thickness of the absorbent core layer 3 (i.e., the absorbent core layer 3 is not completely cut), and the opening depth is preferably equal to or greater than 1mm from the bottom of the absorbent core layer 3.

In order to solve the problem that the sanitary napkin is easy to leak after being used at night, for the sanitary napkin at night, the absorption core layer 3 is subjected to slotting treatment in addition to cutting treatment, as shown in fig. 3, a diversion trench 33 is formed at the joint of the tail part of the absorption core layer 3 and the thigh, the width of the diversion trench 33 is preferably 3mm, the length of the diversion trench is more than or equal to 15mm, and the depth of the diversion trench is preferably more than or equal to 2mm away from the bottom of the absorption core layer 3. The cross section of the diversion trench 33 is preferably an inverted trapezoid, a structure with a wide upper part and a narrow lower part is adopted, and the width of an upper opening is 3 mm. And the liquid diffuses towards the horizontal direction during infiltration, and can effectively prevent the liquid from back-infiltrating at the same time, thereby realizing the effects of quick absorption and water retention. Longitudinal cuts 31 may be provided on both sides of the guide groove 33.

The night sanitary napkin may also be provided with an oblique cut 34 at the fold of the rear end of the absorbent core layer 3 to prevent rear leakage. The vertical length of the oblique cuts 34 is similar to the length of the diversion trenches 33, and the depth is similar to the longitudinal cuts 31 and the transverse cuts 32.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any minor modifications, equivalent changes and modifications made to the above embodiments according to the technical spirit of the present invention still belong to the protection scope of the present invention.
