The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

The first embodiment is as follows:

the existing sanitary towel is easy to cause skin allergy, symptoms such as redness and eruption, or is not fine and soft in touch feeling, and is easy to generate damp, muggy and rewet. In order to solve the above problems, the present embodiment provides a sanitary napkin which has smooth and fine touch, has good moisture absorption and dispersion capability, and can keep dry and comfortable for a long time. As shown in fig. 1, the sanitary napkin comprises a surface layer 1, a flow guide layer 2, an absorption layer 3 and a bottom layer 4 which are sequentially stacked, wherein the surface layer 1 comprises a surface layer main body 11 and wing portions 12, the surface layer main body 11 is positioned above a central absorption area of the absorption layer 3, the wing portions 12 are arranged on two sides of the surface layer main body 11 along the length direction of the surface layer 1, and the surface layer main body 11 is made of non-woven fabrics formed by blending modal fibers and mulberry silk fibers.

Modal fiber is a common textile material, and is often used as an underwear material due to its smooth and fine touch; the mulberry silk fiber material has the characteristics of lightness, thinness and softness, and sericin of the mulberry silk fiber has certain skin nourishing and health care effects, so that the mulberry silk fiber material is a good base material of hygienic products, such as common silk masks, wound dressings and surgical stickers, and the mulberry silk fiber material is used as the base material. In this embodiment, be used for the non-woven fabrics of modal fibre and mulberry silk fibre blending in sanitary towel's top layer 1, not only can inherit the good sense of touch of modal fibre material for the friction of sanitary towel top layer 1 and skin reduces by a wide margin, makes more comfortable noninductive during the use, and the body shape of laminating more has certain nutrition skin and health function in addition. Meanwhile, compared with the method of directly using natural fiber materials such as pure cotton, pure mulberry silk and the like, the cost of the non-woven fabric formed by blending the modal fiber and the mulberry silk fiber is lower.

In the embodiment, the proportion of the modal fibers to the mulberry silk fibers is 70-90% and the proportion of the corresponding mulberry silk fibers is 30-10% by weight, and the non-woven fabric blended in the range has high cost performance. Optionally, the prepared fibers are blended by a spunlace process to prepare a spunlace nonwoven fabric, and the spunlace nonwoven fabric has the characteristics of high strength, difficulty in fluffing, good moisture absorption, good air permeability, soft hand feeling and good drapability, and can further improve the performance of the surface layer 1 material.

Alternatively, the wing protector portion 12 may be a non-woven fabric of 100% modal fiber material, which not only has the smooth and comfortable touch feeling of the modal fiber material, reduces the friction between the wing protector portion 12 and the skin, but also can effectively control the material cost. Specifically, the modal fiber hot air non-woven fabric is used, so that the wing protecting parts 12 are more fluffy and soft, are more attached to the skin and are more comfortable to touch.

Alternatively, in order to prevent the liquid from flowing back during the downward permeation along the thickness direction of the sanitary napkin, as shown in fig. 1, a tapered hole 111 may be provided in the cover body 11 along the thickness direction of the cover body 11, a small-diameter end of the tapered hole 111 may be connected to the flow guiding layer 2, and a large-diameter end of the tapered hole 111 may be located on the upper surface of the cover body 11.

In addition, as shown in fig. 1, the sanitary napkin further comprises a diffusion layer 5, and the diffusion layer 5 is located between the flow guide layer 2 and the absorbent layer 3 to guide the liquid entering into the diffusion layer 5 toward the periphery of the diffusion layer 5. Utilize diffusion layer 5 can advance the main diffusion process of liquid, rather than common main diffusion takes place in absorbed layer 3, can solve absorbed layer 3 like this and form the problem that gel blocks because of local imbibition volume is too big, guarantee that follow-up liquid oozes smoothly downwards to promote the holistic moisture absorption of sanitary towel ability of loosing wet, can keep long-time dry and comfortable.

Alternatively, the diffusion layer 5 is made of a bulky material, and usually, the inside of the bulky material has a large number of pores, and the criss-cross pores enable liquid to flow freely among the pores in the diffusion layer 5, so that the liquid flows towards the periphery of the diffusion layer 5 along the thickness direction of the diffusion layer 5 and seeps down to the periphery of the absorption layer 3 to be absorbed, thereby improving the absorption efficiency of the absorption layer 3 and further improving the moisture absorption and dispersion capacity of the sanitary napkin.

Common fluffy materials are hot air non-woven fabrics or sponges, wherein the hot air non-woven fabrics have the advantages of high bulkiness, good elasticity, soft hand feeling, good air permeability and water permeability and the like, and are good materials for the diffusion layer 5; polyurethane sponge can also be adopted, the sponge is not hydrophilic and has good permeability, and the specific material can be selected according to actual needs, and is not limited herein.

In order to further enhance the diffusivity of the diffusion layer 5 and improve the moisture absorption and dispersion capacity of the sanitary napkin, in the embodiment, functional holes are added on the diffusion layer 5. Alternatively, as shown in fig. 1, the diffusion layer 5 is provided with a plurality of liquid guide holes 51, and the liquid guide holes 51 are through holes penetrating through the upper and lower surfaces of the diffusion layer 5. The through hole has good liquid permeability and good air permeability. Preferably, the liquid guide holes 51 are inclined from top to bottom along the thickness direction of the diffusion layer 5 to the periphery of the diffusion layer 5, so as to accelerate the diffusion of the liquid to the periphery of the diffusion layer 5, thereby improving the overall moisture absorption and dispersion capacity of the sanitary napkin.

Alternatively, as shown in fig. 2, when the central absorption region of the flow guiding layer 2 is provided with pores, the plurality of liquid guiding holes 51 may be only arranged in the circumferential direction of the central absorption region of the diffusion layer 5, so that in the process of making the liquid seep from the flow guiding layer 2 to the diffusion layer 5, the central absorption region of the diffusion layer 5 has a larger resistance to the liquid relative to the periphery thereof, so that the liquid naturally flows to the periphery with a relatively lower resistance in the diffusion layer 5, thereby improving the diffusibility.

Example two:

the present embodiment provides another structure for enhancing the diffusibility of the diffusion layer 5, which is different from the first embodiment in that, as shown in fig. 3, a plurality of liquid guiding holes 51, such as two liquid guiding holes 51, are provided in the diffusion layer 5 in a direction perpendicular to the thickness direction of the diffusion layer 5. When the liquid flows downwards to the first liquid guiding hole 51 along the thickness direction of the diffusion layer 5, the liquid continues to flow along the axial direction of the hole, so that the liquid is diffused to the periphery of the diffusion layer 5 and the second liquid guiding hole 51, the diffusivity is improved, and the overall moisture absorbing and dissipating capacity of the sanitary towel is further improved.

Alternatively, as shown in fig. 4, diffusion holes 52 may be further provided in the diffusion layer 5, and one end of the diffusion holes 52 is communicated with the fluid guide layer 2, and the other end is communicated with the fluid guide holes 51. By such cross-channels, the liquid diffusion speed will be greatly increased. More preferably, the diffusion holes 52 may be inclined from the top to the bottom in the thickness direction of the diffusion layer 5 toward the periphery of the diffusion layer 5, so that the diffusion speed is further increased.

Example three:

the present embodiment provides another structure for enhancing the diffusibility of the diffusion layer 5, which is different from the first embodiment in that, as shown in fig. 5 and 6, a liquid guiding groove 53 is provided on the diffusion layer 5, and the liquid guiding groove 53 extends from the central absorption region of the diffusion layer 5 to the periphery of the diffusion layer 5. After the liquid enters the diversion trenches 53, the liquid flows along the length direction of the diversion trenches 53, so that the liquid diffusion mainly occurs in the diffusion layer 5, the liquid can continuously seep downwards during the diffusion flowing period, and the distance of the liquid seeping downwards and penetrating through the diffusion layer 5 is reduced due to the arrangement of the diversion trenches 53, so that the liquid can reach the absorption layer 3 more quickly, and the whole moisture absorption and dispersion capacity of the sanitary towel is improved.

The specific arrangement of the flow guide layer 2, the absorption layer 3 and the bottom layer 4 is conventional and will not be described herein.

The above embodiments have been described only the basic principles and features of the present invention, and the present invention is not limited by the above embodiments, and is not departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
