Description
Technical field
This utility model relates to sanitary towel's articles for use technical field, particularly relates to a kind of dry and comfortable ventilating type sanitary napkin with multifunctional composite core sheet.
Background technology
Sanitary towel is a kind of material of tool absorbing power, high molecular polymer and high molecular polymer extrusion coating paper that main material forms for cotton, adhesive-bonded fabric, paper pulp or above material complex, the design of side is mainly used to prevent side leakage, gum is waterproof material, menses can be retained in cotton wool to the menses that flow out from vagina while being used for absorbing women's menstrual onset; Existing sanitary towel, generally include surface layer, absorbent cores and bottom, absorbent cores is arranged between surface layer and bottom, and surface layer has higher water penetration, and bottom has higher water-resisting property, in use, because the water absorbing properties of absorbent cores is limited, and the permeability of surface layer is better, thereby easily occurs that menses overflow, surface layer is comparatively moistening, is difficult to ensure the problem of the dry and comfortable breathability of sanitary towel.
Utility model content
For solving the problems of the technologies described above, this utility model provides that a kind of water absorbing properties is higher, surface layer can effectively keep the dry and comfortable and ventilative dry and comfortable ventilating type sanitary napkin with multifunctional composite core sheet.
The dry and comfortable ventilating type sanitary napkin with multifunctional composite core sheet of the present utility model, comprise surface layer, absorbent cores and bottom, between described surface layer and absorbent cores, be also provided with unidirectional layer, described unidirectional layer comprises the basal layer with water isolating, on described basal layer, be arranged at intervals with multiple permeable holes, the diameter at described permeable hole top is greater than the diameter of bottom, the bottom of described permeable hole is connected with Unidirectional water permeable valve, described Unidirectional water permeable valve comprises upper film and the lower film that side is connected and is sealed, described upper film and lower film top are connected to the both sides of described permeable hole bottom, the aperture of described upper film and the bottom perforate of lower film is less than the aperture of top perforate, described absorbent cores comprises at least three layers of identical single sandwich layer, and the bottom interval of described single sandwich layer is provided with the projection of multiple dome-types.
Further, described unidirectional layer is for breathing the unidirectional layer of paper.
Further, described surface layer is bamboo fibre cloth cover.
Further, the density of described permeable hole is not less than 5/cm
2, the density of described projection is not less than 1/cm
2.
Compared with prior art the beneficial effects of the utility model are: comprise surface layer, absorbent cores and bottom, between surface layer and absorbent cores, be also provided with unidirectional layer, unidirectional layer comprises the basal layer with water isolating, on basal layer, be arranged at intervals with multiple permeable holes, the diameter at permeable hole top is greater than the diameter of bottom, the bottom of permeable hole is connected with Unidirectional water permeable valve, Unidirectional water permeable valve comprises upper film and the lower film that side is connected and is sealed, upper film and lower film top are connected to the both sides of permeable hole bottom, the aperture of upper film and the bottom perforate of lower film is less than the aperture of top perforate, absorbent cores comprises at least three layers of identical single sandwich layer, and the bottom interval of single sandwich layer is provided with the projection of multiple dome-types, it should be noted that, Unidirectional water permeable valve in this utility model, and the valve of nonmetal structure, but formed by upper film bonded to each other and lower film, in the time there are a large amount of menses on surface layer, under the water sorption of osmosis and absorbent cores, menses flow between upper film and lower film from permeable hole, and then inflow absorbent cores, when the menses absorption in absorbent cores is saturated or sanitary towel is under pressure, when menses are wanted oppositely to flow out, upper film and lower film be subject to both sides fluid pressure and occur being affixed and self-closing and, therefore Unidirectional water permeable valve has one-way flow characteristic, meanwhile, absorbent cores comprises multilamellar list sandwich layer, and the projection between single sandwich layer has stoped single sandwich layer pressurized to extrude menses, thereby has improved the water absorption of absorbent cores, prevents that menses from overflowing simultaneously, in addition, Unidirectional water permeable valve can be accomplished in several ways, and can under basal layer, glue and stick, and also can be set to have elastic long fibre tight weave by basal layer, then uses the mode of acupuncture, stings out the unidirectional layer of similar structures.
Brief description of the drawings
Fig. 1 be this utility model cut open to structural representation.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples are used for illustrating this utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, the dry and comfortable ventilating type sanitary napkin with multifunctional composite core sheet of the present utility model, comprise surface layer 1, absorbent cores 2 and bottom 3, between surface layer 1 and absorbent cores 2, be also provided with unidirectional layer 4, unidirectional layer 4 comprises the basal layer 41 with water isolating, on basal layer, be arranged at intervals with multiple permeable holes 42, the diameter at permeable hole 42 tops is greater than the diameter of bottom, the bottom of permeable hole 42 is connected with Unidirectional water permeable valve 43, Unidirectional water permeable valve 43 comprises upper film 431 and the lower film 432 that side is connected and is sealed, upper film 431 and lower film 432 tops are connected to the both sides of permeable hole 42 bottoms, the aperture of upper film 431 and lower film 432 bottom perforates is less than the aperture of top perforate, absorbent cores 2 comprises at least three layers of identical single sandwich layer 21, and the bottom interval of single sandwich layer is provided with the projection 22 of multiple dome-types, it should be noted that, Unidirectional water permeable valve in this utility model, and the valve of nonmetal structure, but formed by upper film bonded to each other and lower film, in the time there are a large amount of menses on surface layer, under the water sorption of osmosis and absorbent cores, menses flow between upper film and lower film from permeable hole, and then inflow absorbent cores, when the menses absorption in absorbent cores is saturated or sanitary towel is under pressure, when menses are wanted oppositely to flow out, upper film and lower film be subject to both sides fluid pressure and occur being affixed and self-closing and, therefore Unidirectional water permeable valve has one-way flow characteristic, meanwhile, absorbent cores comprises multilamellar list sandwich layer, and the projection between single sandwich layer has stoped single sandwich layer pressurized to extrude menses, thereby has improved the water absorption of absorbent cores, prevents that menses from overflowing simultaneously, in addition, Unidirectional water permeable valve can be accomplished in several ways, and can under basal layer, glue and stick, and also can be set to have elastic long fibre tight weave by basal layer, then uses the mode of acupuncture, stings out the unidirectional layer of similar structures.
