The embodiment of the utility model provides a suspension core body one-piece type sanitary towel, which is specially designed for women with good physical fitness, large menstrual volume and sensitive skin.

Referring to fig. 1, the one-piece sanitary napkin with suspended core in the present embodiment comprises a topsheet 1, a core 2, a leakage-preventing backsheet, and flaps 4.

As shown in figure 1, the cover 1 covers the upper surface and the side edges of the core body 2, and after being folded along the side edges of the core body 2, extends to both sides of the bottom to form wings 4. The surface layer 1 and the wings 4 form a one-piece structure, do not need extra cutting and sticking processes, are made of the same continuous material, and are stuck with the leakage-proof bottom layer 3 at the bottom. The bottom of the middle part of the core body 2 is bonded with the leakproof bottom layer 3 to form a suspension structure for absorbing the permeation liquid.

The surface layer 1 is made of spun-bonded composite cotton net spunlace non-woven fabric with a microporous structure and is used for one-way moisture conduction; the surface layer 1 comprises a spun-bonded surface and a cotton net surface, the cotton net surface adopts a mesh structure and serves as a skin-sticking surface, and the spun-bonded surface is made of a hydrophilic material with micro meshes. The capillary effect is formed by the mesh structure of the cotton mesh surface and the tiny mesh holes of the spun-bonded surface, and the liquid which sideslips to the side edge and the bottom of the core body 2 is absorbed into the core body 2 to play the roles of flow guiding and instant absorption, thereby forming the one-way moisture guiding effect. The middle of the surface layer 1 is pressed with a diversion trench for accelerating the imbibition speed and increasing the diffusion length. The spun-bonded composite cotton net spunlace non-woven fabric used as the surface layer material has good liquid absorption and permeability and can quickly absorb blood; the air permeability is excellent, and bacteria are not easy to breed; meanwhile, the spunlace nonwoven fabric of the spun-bonded composite cotton net is soft in texture, natural and non-irritant, and is suitable for common people and people with anaphylaxis.

In addition, the surface layer 1 can also be made of all-cotton spunlace non-woven fabrics subjected to semi-water repellent treatment. When the all-cotton spunlace non-woven fabric is adopted as the surface layer, the surface layer 1 comprises a skin-contacting surface layer, a flow guide layer and an absorption layer, wherein the flow guide layer is arranged between the skin-contacting surface layer and the absorption layer. Wherein, the skin-facing layer can be in a plain weave or a mesh structure. Wherein, the plain weave structure has the advantage that comfortable friction dynamics is little, and the mesh structure has the advantage that absorbs rapidly, the gas permeability is stronger, drier and comfortable. Meanwhile, the surface layer of the all-cotton spunlace non-woven fabric is soft in texture, natural and environment-friendly, and not easy to cause allergy, so that the all-cotton spunlace non-woven fabric is also suitable for sensitive women in menstrual period, and the dryness of the surface can be improved by the semi-water repellent process.

As shown in FIG. 2, the single-piece sanitary napkin with suspended core in the present embodiment may further comprise a three-dimensional containment flap 5, wherein the three-dimensional containment flap 5 is symmetrically disposed between the core 2 and the two side flaps 4 for preventing side leakage. Under the condition that the three-dimensional guard 5 exists, the three-dimensional guard 5 protrudes upwards from the surface layer 1 to extend to form a one-piece structure; the wings 4, the three-dimensional enclosure 5 and the surface layer 1 are continuously made of the same material. The height of the core body 2 is not higher than that of the three-dimensional enclosure 5. The bottom of the middle part of the core body 2 is bonded with the leakage-proof bottom layer 3 to form a suspended core body structure. For example, the central part of 40% in the middle of the bottom of the core body 2 is directly bonded with the leakage-proof bottom layer 3, and the design ensures that the menstrual blood which laterally slides to the side edge and the bottom can be absorbed through the side surface and the bottom of the core body 2, thereby quickening the absorption speed of the sanitary towel, increasing the absorption part, increasing the instant absorption capacity, reducing the side leakage risk, and preventing the problems of displacement, fault, lump and the like.

In the present embodiment, the core 2 includes an absorber and a clad covering the absorber; wherein, the absorber is made of one of SAP, wood pulp and absorbent cotton pad with SAP high molecular particles; the coating layer is made of all-cotton non-woven fabric or toilet paper. The absorbent body can also be made of SAP, wood pulp, wet-strength paper composite. Wherein the absorbent cotton pad is made of spunlace cotton.

The leak-proof bottom layer 3 is made of polyethylene PE ventilated membrane or ventilated non-woven fabric.

In the embodiment, the cotton fibers are made of certified natural cotton (Mei cotton, Australian cotton and Xinjiang cotton), have excellent quality, are safe and reliable, can be naturally degraded and are environment-friendly. And the spunlace process is efficient, energy-saving and environment-friendly.

The suspension core body one-piece sanitary napkin provided by the embodiment adopts the absorption design of the spun-bonded composite cotton net spunlace non-woven fabric coated suspension core body with a microporous structure, so that the absorption surface is closer to the human body, and meanwhile, the core body is more close to the skin and comfortable, the side leakage prevention effect is better, and the allergy phenomenon is effectively reduced.

It is right to have used specific individual example above the utility model discloses expound, only be used for helping to understand the utility model discloses, not be used for the restriction the utility model discloses. To the technical field of the utility model technical personnel, the foundation the utility model discloses an idea can also be made a plurality of simple deductions, warp or replacement.
