Description
Technical field
The invention belongs to hygroscopicity hygienic article technical field, particularly a kind of antiseep permeable sanitary articles for use.
Background technology
At present, traditional hygienic article on market all adopts casting films or ventilative casting films as bottom, play waterproof or micro-breathing freely but fluid-tight effect, but the in fact breathability extreme difference of casting films own, that baby, women or the privates skin of adult are tender and lovely all especially, will with pruritus during the air-locked hygienic article of life-time service, erythema, damp and hot, the problems such as Skin pigmentation.
Existing conventional sanitation articles for use are as feminine sanitary napkin, sanitary towel, baby paper diaper, adult diapers etc. uses ventilative casting films to replace air-locked casting films, effectively can leak into outside by barrier liquid on the one hand, ventilative casting films has small air-vent on the other hand, can through the gas of denier, but, this breathability be based upon the temperature difference of inside and outside or differing pressure larger when, especially in summer, when human body perineal position body temperature and ambient temperature are more or less the same, or when not having pressure to act on hygienic article, people are when using hygienic article, due to almost without air permeable effect, still can feel moist, sultry, be easy to breed bacteria, cause allergic phenomena, or cause gynaecopathia, decubital ulcer etc., simultaneously in comfort level, because casting films or ventilative casting films are made of plastics, not only easily be pasted onto on skin by human body fluid, to the extremely uncomfortable sensation of people, also because its pliability is poor, in use easy abraded skin, in environmental protection, the chemical molecular structure of casting films or ventilative casting films has great stability, pole difficult degradation.
In addition, publication CN202801950 provides a kind of breathable environment-protective sanitary towel, it adopts refuses water non-woven fabrics and replaces traditional casting films or ventilative casting films as sanitary towel's counterdie, and absorber is provided with from bottom to top on counterdie, guide layer, convex body, surface layer, solve traditional material while solving the problem of traditional casting films or ventilative casting films permeability difference not easily to degrade, easily cause the problem of environmental pollution, but the structural design of this sanitary towel has obvious following defect: it is in the structural design of this sanitary towel, adopt between the convex body with absorbing fluid effect and absorber guide layer make liquid very easily under ooze, and water repellent layer only mention in structural design adopt one deck refuse water non-woven fabrics as sanitary towel's counterdie, and refuse water non-woven fabrics itself and not can accomplish completely waterproof, especially its water penetration lower is slightly being exerted pressure clearly, not there is the effect of leakproof, in addition, when employing refuses water non-woven fabrics as sanitary towel's counterdie, water effect is refused to the requirement also with certain grammes per square metre refusing water non-woven fabrics, if even if the water non-woven fabrics of refusing selecting every Gram Mass too low uses multiple-layer stacked also can not reach the effect of refusing water in order to reach certain.Although therefore this sanitary towel solves the problem of conventional sanitary towels poor air permeability, leakage problems is very easily caused to cause this sanitary towel not have practicality.
Summary of the invention
The object of the present invention is to provide a kind of antiseep permeable sanitary articles for use effectively preventing seepage simultaneously to have fine air permeability.
To achieve these goals, technical solution of the present invention is as follows:
These antiseep permeable sanitary articles for use comprise at least two-layer absorption composite bed and overlay on the top layer of described absorption composite bed upper surface, and described absorption composite bed comprises the absorptive core refused water nonwoven layer and refuse water nonwoven layer upper surface described in overlaying on.
Described absorption composite bed comprises the absorptive core refused water nonwoven layer and refuse water nonwoven layer upper surface described in overlaying on.Wherein, the liquid that described absorptive core is discharged for absorbing human body, and refuse water nonwoven layer for preventing fluid seepage to outside hygienic article, namely replace traditional hygienic article to be used as the casting films of counterdie or the combination of ventilative casting films and absorptive core.It should be noted that, refuse water non-woven fabrics itself not waterproof as casting films or ventilative casting films, but one is moderate by fibrous pliability, porous, self do not absorb water, and the material that moisture content is low, its loose structure causes its breathability good, simultaneously due to fiber self with hydrophobic group make to refuse water nonwoven surface and have and certain refuse outlet capacity, in simple terms, namely refusing water non-woven fabrics can make liquid refuse to penetrate under after the short stay of water nonwoven surface to refuse water non-woven fabrics, and its seepage velocity also can be accelerated under light pressure effect.
At present, refuse water non-woven fabrics and mainly comprise two large classes: the first kind refuses water non-woven fabrics be non-woven fabrics through conventional water-repelling agent emulsion or solution impregnation, drying, bake after, one deck hydrophobic group is become at fabric face, reach waterproof object, its breathability is slightly different with different water-repelling agents, but water proofing property is unsatisfactory, water pressure resistance is also low; Equations of The Second Kind refuses the microporosity matter that water non-woven fabrics mainly utilizes coating and thin film, namely by surface tension that chemical method makes the hole of non-woven fabrics reduce or make to refuse water nonwoven cloth material critical surface tension to be less than liquid (Ru Shui, oil) by coating and film, reach the effect of permeable watertight, but the while of so not only increasing cost, the reduction of hole must cause weakening of permeability.
Visible, on hygienic article, water proofing property and breathability are a pair conflicting indexs.Antiseep permeable sanitary articles for use provided by the invention are not started with from material modification and to be improved its water proofing property and breathability, but utilize the performance characteristics of refusing water non-woven fabrics while the original permeability of maintenance, reach the effect of effective liquidproof seepage, cost is down to minimum simultaneously.
As previously mentioned, refusing water non-woven fabrics itself not can accomplish completely waterproof, especially more obvious in its water penetration lower of slightly exerting pressure, therefore devise and refuse water non-woven fabrics upper surface at monolayer and be covered with one deck absorptive core and formed and absorb composite bed, and obtain a kind of hygienic article having fine air permeability and impermeability concurrently by being covered with top layer at upper surface after the superposition of at least two-layer absorption composite bed.Its principle that can realize impermeability is utilize to refuse water non-woven fabrics top layer and have the time that hydrophobic group enables liquid oppositely absorb to absorptive core one in the feature of refusing the short stay of water nonwoven surface, refuse water non-woven fabrics also can not caused seepage by absorbing even if make liquid penetrate into, and adopting at least two-layer absorption composite laminate to add design is because single-layer absorption composite bed is when repeatedly 5mL liquid is toppled over simultaneously with 0.5kg light pressure in interval, have Seepage to occur, and when absorption composite laminate add to two-layer after, even if then also there will not be seepage under more than the pressure of 3kg under the same conditions, namely fabulous antiseep effect is reached.
It is to be noted simultaneously, although the above-mentioned first kind namely can be used in the use refusing water non-woven fabrics to refuse water non-woven fabrics, also above-mentioned Equations of The Second Kind can be used to refuse water non-woven fabrics or other has the product better refusing water effect, but when adopting this technical scheme, wherein refuse water non-woven fabrics to use the above-mentioned first kind to refuse water non-woven fabrics both can to have ensured not only to breathe freely but also fluid-tight effect, low, the environmental protection of cost simultaneously, easily to degrade.
In this hygienic article, described in refuse water nonwoven layer adopt grammes per square metre at 17 ~ 340g/m
2, corresponding compacting thickness be 0.1 ~ 5.0mm refuse water non-woven fabrics.Wherein, refuse water non-woven fabrics to select to adopt every square meter how many grammes per square metres (g/m
2) weigh, be the general criterion in industry.Pass through lot of experiment validation, when the grammes per square metre and the hygienic article of refusing water non-woven fabrics making of thickness outside above-mentioned scope of refusing water non-woven fabrics do not possess practicality, the too low meeting of grammes per square metre because refuse water non-woven fabrics hole excessive cause liquid refusing the time of staying on water non-woven fabrics too short seepage, grammes per square metre is too high, adds unnecessary cost.
Preferably, refusing water nonwoven layer described in adopts grammes per square metre at 20 ~ 200g/m
2, corresponding compacting thickness be 0.1 ~ 1.0mm refuse water non-woven fabrics.
Wherein, the multilamellar for superposition absorbs composite bed, formed every layer absorb that composite bed uses refuse that water non-woven fabrics can select grammes per square metre identical with thickness refuse water non-woven fabrics, also can select grammes per square metre different with thickness refuse water non-woven fabrics.
It is to be noted, select the grammes per square metre of refusing water non-woven fabrics higher, the thickness of compacting is less, material must be caused harder, its pliability will inevitably decline, can envision and refuse that water non-woven fabrics grammes per square metre when choosing is too high not only can raise the cost, make the use pliability after hygienic article and comfort level must decline.
Described absorptive core is overlying at least on one deck absorbed layer B at least one deck absorbed layer A, at least one deck absorbed layer A, or at least one deck absorbed layer B package/parcel overlays on the skin of at least one deck absorbed layer A.
Wherein, the skin that described at least one deck absorbed layer B is wrapped at least one deck absorbed layer A specifically refers to that at least last layer absorbed layer B is wrapped in the outer surface of absorbed layer A completely and is fixed as one by glue, and the skin that described at least one deck absorbed layer B is coated at least one deck absorbed layer A specifically refers to that at least one deck absorbed layer B is arranged on the lower floor of at least one deck absorbed layer A and is coated on the both sides of the upper surface of described absorbed layer A and is fixed as one by glue.
