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, a grooved absorbent core layer 3 and a barrier backing layer 4 arranged in that order from top to bottom. Secretion such as menstrual blood or urine flows into the slotted absorbent core layer 3 from the surface nonwoven fabric layer 1, the slotted absorbent core layer 3 absorbs and stores the secretion, and the impermeable bottom film layer 4 plays a role in preventing the secretion from leaking.

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, which retains excretions such as menstrual blood within the absorbent core layer. The sanitary napkin may optionally further comprise a release paper (not shown). 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 slotted absorption core body layer 3, and can quickly guide secretion in the surface non-woven fabric layer 1 to the slotted absorption core body layer 3, so that dryness of the surface non-woven fabric layer 1 is ensured, and the use comfort is improved. The material and structure of the flow guiding layer 2 are the prior art, and are not described herein again.

The slotted absorbent core layer 3 may optionally include a first absorbent layer 31, a first slotted absorbent layer 32, a flow guiding interlayer 33, a second slotted absorbent layer 34 and a second absorbent layer 35 arranged in this order from top to bottom.

The first absorption layer 31 and the second absorption layer 35 are respectively used as the surface layer and the bottom layer of the slotted absorption core layer 3, and are made of dust-free paper, toilet paper or non-woven fabric, so that the elasticity and the softness of the first absorption layer 31 and the second absorption layer 35 are improved, and the slotted absorption core layer has good absorbability and good water retention capacity. The first slotted absorbent layer 32 and the second slotted absorbent layer 34 are preferably made of high molecular water-absorbent resin, and have good water absorption and retention properties. The flow guiding interlayer 33 is preferably a fluffy non-woven fabric, and the fibers in the flow guiding interlayer are loose, so that the flow guiding interlayer can accommodate the secretion in the first slotted absorbent layer 32 and guide the secretion to the second slotted absorbent layer 34 quickly.

Preferably, referring to fig. 2, the first slotted absorbent layer 32 and the second slotted absorbent layer 34 have the same structure, the first slotted absorbent layer 32 has a plurality of first absorption channels 321, and the second slotted absorbent layer 34 has a plurality of second absorption channels 341 for fast diversion and water storage. In this embodiment, the first absorbing guiding groove 321 and the second absorbing guiding groove 341 are longitudinally arranged to form a plurality of fast guiding channels for fast absorption. The longitudinal sections of the first absorption flow guide groove 321 and the second absorption flow guide groove 341 are preferably inverted trapezoids, and the result of the upper width and the lower width is adopted, so that the liquid infiltration is facilitated, the liquid infiltration can be effectively prevented, and the effects of quick absorption and water retention are realized. Referring to fig. 3, the plurality of first absorbing guiding grooves 321 are arranged along the transverse direction of the first slotted absorbing layer 32 at intervals, so as to improve the overall guiding capacity. Alternatively, the transverse spacing between adjacent first absorption channels 321 and between adjacent second absorption channels 341 is 25mm, and the groove width is 5mm to 25 mm. In other embodiments, the width and spacing of the channels can be adjusted according to the size of the sanitary napkin and the requirement for the water diversion and retention capacity.

In other embodiments, the first absorbing channels 321 and the second absorbing channels 341 may be disposed obliquely, i.e., at an angle with respect to the longitudinal direction, and form multi-directional flow guiding channels in the first slotted absorbing layer 32 and the second slotted absorbing layer 34, so as to promote isotropy of the flow guiding capability of the first slotted absorbing layer 32 and the second slotted absorbing layer 34. In addition, the cross sections of the first absorption guiding groove 321 and the second absorption guiding groove 341 may also be set to be triangular, rhombic, hexagonal, or even circular arc-shaped, and the like, which is not limited herein.

The secretion is drained to the slotted absorption core layer 3 through the diversion layer 2, the secretion is partially absorbed by the first absorption layer 31 and is drained to the first slotted absorption layer 32, the high-molecular water-absorbent resin in the first slotted absorption layer 32 is rapidly absorbed, meanwhile, part of the secretion flows into a rapid diversion and water retention channel formed by the first absorption diversion groove 321, the first absorption diversion groove 321 stores part of the secretion therein and rapidly diverts part of the secretion to the diversion interlayer 33, the diversion interlayer 33 further diverts the secretion to the second slotted absorption layer 34, and the rapid diversion and water retention channel formed by the second absorption diversion groove 341 further absorbs and drains the secretion, so that the whole slotted absorption core layer 3 rapidly absorbs the secretion and has good water retention capacity.

It should be noted that, in other embodiments, the second slotted absorption layer 34 may not be provided, and only the first slotted absorption layer 32 is provided, so as to meet the requirement of fast absorption and water storage, the overall structure is simpler, the processing is convenient, and at this time, the diversion interlayer 33 may also be removed correspondingly. Certainly, in other embodiments, a third slotted absorption layer, a fourth slotted absorption layer, and the like may be further provided to further achieve the purposes of ultra-fast absorption and large amount of water storage, and meet the use requirements of different occasions or stages, at this time, a diversion interlayer 33 may also be provided between the second slotted absorption layer 34 and the third slotted absorption layer, and between the third slotted absorption layer and the fourth slotted absorption layer, to further improve the longitudinal diversion capability.

In the sanitary napkin provided by the embodiment, the slotted absorbent core layer 3 is arranged into a multilayer structure, and the first slotted absorbent layer 32 and the second slotted absorbent layer 34 are respectively provided with the plurality of first absorbent channels 321 and the plurality of second absorbent channels 341, so that the overall water absorption capacity and water retention capacity of the whole sanitary napkin are effectively improved.

It should be noted that the foregoing is only a preferred embodiment of the present invention and the technical principles applied. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, although the present invention has been described in greater detail with reference to the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the scope of the present invention.
