Description
Technical Field
The utility model relates to the technical field of disposable sanitary products, in particular to novel composite pull-up pants.
Background
At present, the living standard of people is better, the comfort and the functional requirements on disposable sanitary products are higher and higher, and the demand is also higher and higher. In disposable sanitary articles, the fluffy nonwoven fabric is widely applied, and the most main application is the shaping of the core body. When the core body is formed, the fluffy non-woven fabric is mainly used for bearing and embedding water-absorbing macromolecules. Such as Chinese patent publication No.: CN211512338U discloses a fluffy non-woven composite core, which is formed by connecting a first cover layer, a hot melt adhesive layer, a first super absorbent resin layer, a high fluffy non-woven layer, a second super absorbent resin layer, a hot melt adhesive layer and a second cover layer from top to bottom, wherein the high fluffy non-woven layer is composed of a surface layer, a bottom layer and a middle layer between the surface layer and the bottom layer, the surface layer and the bottom layer are long fiber net layers, and the middle layer is a mixed fiber net layer or fluff pulp fiber net layer and is connected with the adjacent bottom layer and surface layer into a whole. The mixed fiber web layer takes a hot-melt superfine short fiber web as a framework structure, and fluff pulp fibers are fixedly combined in the hot-melt superfine short fiber web. The long fiber web layer is a coarse fiber web layer, and the fiber size in the coarse fiber web layer is 3.0-10.0D, and the length is 38-51mm.
Under the existing technological conditions, coarse denier fibers are used for upper layer fibers and lower layer fibers of the fluffy cloth, the fluffy cloth is large in pores, so that the product is easy to deform, the high polymer is lost in operation under the state of air suction, the high polymer is reduced, the absorption effect is poor, the production cost is increased when the fluffy cloth is applied to the product, and the quality of the product is changed, so that the absorbability and the diffusivity of the core body are reduced.
Disclosure of Invention
Therefore, the utility model provides a novel composite pull-up diaper, which solves the technical problem that the prior pull-up diaper is easy to cause polymer loss when an absorbent core is made of fluffy non-woven fabrics.
In order to achieve the above purpose, the present utility model adopts the following technical scheme: the utility model provides a novel compound pull-up trousers, includes skin-friendly top layer, compound core and impervious bottom layer from top to bottom in proper order, compound core includes a compound non-woven fabrics that has the gas permeability and locates the upper non-woven fabrics of compound non-woven fabrics top, compound non-woven fabrics includes from top to bottom sets gradually fibrous layer and elasticity non-woven fabrics, it has polymer water absorption granule to inlay in the fibrous layer.
Further improved, when the elastic non-woven fabric is in a natural state, the average gap of the fiber layer is smaller than the average diameter of the high molecular water absorption particles.
Further improved, the fiber layer is fluffy non-woven fabric.
Further improved, the elastic non-woven fabric comprises a skin-friendly non-woven fabric and an elastic membrane from top to bottom, and the elastic membrane is provided with air holes.
Further improved, the fiber fineness of the fiber layer is 4-12D.
By adopting the technical scheme, the utility model has the beneficial effects that: according to the utility model, the elastic composite non-woven fabric is arranged, when the high polymer water absorbing particles are added, the composite non-woven fabric can be transversely and longitudinally stretched, so that the pores of the fiber layer are larger than the average diameter of the high polymer water absorbing particles, the high polymer water absorbing particles are added, and when the composite non-woven fabric is restored to a natural state, the stable clamping of the high polymer water absorbing particles can be realized, and the running loss of the high polymer water absorbing particles is avoided.
Drawings
FIG. 1 is a schematic cross-sectional view of an embodiment of the present utility model;
fig. 2 is a schematic cross-sectional structure of a composite core according to an embodiment of the present utility model.
Icon:
1. a skin-friendly surface layer; 2. a composite core; 21. a fibrous layer; 22. skin-friendly non-woven fabric; 23. an elastic film; 24. high molecular water-absorbing particles; 25. an upper layer of non-woven fabric; 26. ventilation holes; 3. a liquid impermeable backsheet.
Detailed Description
The utility model will now be further described with reference to the drawings and detailed description.
Referring to fig. 1-2, this embodiment provides a novel composite pull-up pants, from top to bottom in order including skin-friendly top layer 1, composite core 2 and liquid impermeable bottom layer 3, composite core 2 includes a composite non-woven fabrics that has the gas permeability and locates the upper non-woven fabrics 25 of composite non-woven fabrics top, composite non-woven fabrics includes from top to bottom sets gradually fibrous layer 21 and elasticity non-woven fabrics, fibrous layer 21 embeds has polymer water absorption granule 24, when elasticity non-woven fabrics is in natural state, the average space of fibrous layer 21 is less than polymer water absorption granule 24's average diameter.
In this embodiment, the fiber layer 21 is a fluffy nonwoven fabric, the fiber fineness of the fluffy nonwoven fabric is 4-12D, the elastic nonwoven fabric sequentially comprises a skin-friendly nonwoven fabric 22 and an elastic membrane 23 from top to bottom, and the skin-friendly nonwoven fabric 22 has air permeability, so that the elastic membrane 23 is provided with air holes 26, the purpose that the air holes 26 do not penetrate through the skin-friendly nonwoven fabric 22 is to avoid that a polymer water absorbing material penetrates through the elastic nonwoven fabric when applied, and cannot land on the composite nonwoven fabric, and in practical application, the elastic membrane 23 can also be replaced by an elastic band, but the fixing effect of the elastic membrane on the polymer water absorbing particles is not as good as that of the elastic membrane.
According to the utility model, by arranging the elastic composite non-woven fabric, when the polymer water-absorbing particles 24 are added, the composite non-woven fabric can be transversely and longitudinally stretched, so that the pores of the fiber layer 21 are larger than the average diameter of the polymer water-absorbing particles 24, and the polymer water-absorbing particles 24 are added, and when the composite non-woven fabric is restored to a natural state, the stable clamping of the polymer water-absorbing particles 24 can be realized, and the running loss of the polymer water-absorbing particles 24 is avoided.
While the utility model has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the utility model as defined by the appended claims.
