Description
Technical field
This utility model belongs to hygroscopicity sanitary towel technical field, particularly a kind of antiseep air permeable sanitary towel.
Background technology
At present, traditional sanitary towel 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, and the privates skin of women is 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.
The many uses of existing Traditional Female sanitary towel casting films of breathing freely replaces 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 female perineum portion body temperature and ambient temperature are more or less the same, or when not having pressure to act in sanitary towel, women is when using sanitary towel, due to almost without air permeable effect, therefore still can feel moist, sultry, be easy to breed bacteria, cause allergic phenomena, more seriously gynaecopathia can be caused, 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 is only mentioned employing and is refused water non-woven fabrics as sanitary towel's counterdie in structural design, 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.
Utility model content
The purpose of this utility model is to provide a kind of antiseep air permeable sanitary towel effectively preventing seepage simultaneously to have fine air permeability.
To achieve these goals, technical solutions of the utility model are as follows:
This antiseep air permeable sanitary towel comprises at least two-layer absorption composite bed and overlays on the top layer of described absorption composite bed upper surface, described absorption composite bed comprises the absorptive core refused water nonwoven layer and refuse water nonwoven layer upper surface described in overlaying on, described in refuse water nonwoven layer and adopt grammes per square metre at 17 ~ 340g/m
2, corresponding compacting thickness be 0.1 ~ 5.0mm refuse water non-woven fabrics.
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 sanitary towel, namely replace traditional sanitary towel 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 chemical drains 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 is refused after water non-woven fabrics is through conventional water-repelling agent emulsion or solution impregnation, drying, bakes, 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, the water proofing property of sanitary towel and breathability are a pair conflicting indexs.The antiseep air permeable sanitary towel that this utility model provides not is 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.
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 sanitary towel that refuse 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.
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 sanitary towel 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.

With reference to sanitary towel's industry standard and those skilled in the art detection experience in sanitary towel's industry, in following sanitary towel articles for use, adopt the 0.5kg external world to exert pressure test, leakproof test result is as shown in table 2 below.
Table 2:
Table 2 is depicted as the different purposes for sanitary towel, by refusing the adjustment of water non-woven fabrics grammes per square metre with the number of plies of absorption composite bed, tests sanitary towel's leakageresistance in actual applications.
Through above-mentioned test, adopt grammes per square metre (g/m
2) scope is unsatisfactory in the leakageresistance of refusing the sanitary towel that water non-woven fabrics is made of m≤10 and 10 < m≤16, is 16g/m when selecting grammes per square metre
2refuse absorption composite laminate that water non-woven fabrics makes when adding to four layers, still can there is micro-seepage; And when the grammes per square metre of refusing water non-woven fabrics is 17g/m
2time, can there is obvious seepage in single-layer absorption composite bed, only have micro-seepage after two-layer absorption composite bed superposition, and ne-leakage after absorbing composite bed superposition when three layers; Continue increase and refuse the grammes per square metre of water non-woven fabrics to 18g/m
2, be ne-leakage after two-layer absorption composite bed superposition, and when the grammes per square metre of refusing water non-woven fabrics is increased to 20g/m
2, after adopting two-layer absorption composite bed to superpose, even if when the volume of the test liquid of toppling over is by 5mL value added 7mL at every turn, also can not there is seepage in the structure adopting two-layer absorption composite bed to superpose; When the grammes per square metre of refusing water non-woven fabrics is increased to 50g/m
2, micro-seepage can be there is equally in single-layer absorption composite bed, even and if the structure adopting two-layer absorption composite bed to superpose time the volume of test liquid of at every turn toppling over be increased to 10mL by 5mL seepage also can not occur; When the grammes per square metre of refusing water non-woven fabrics is increased to 100g/m
2.Time, when the volume of the test liquid of at every turn toppling on two-layer absorption composite bed overlaying structure is 10mL, seepage can not occurs, can know by inference equally, when the grammes per square metre of refusing water non-woven fabrics continues to increase, two-layer absorption composite bed overlaying structure effectively can prevent seepage.Visible, if considered, when the grammes per square metre of refusing water non-woven fabrics is preferably 20g/m from cost simultaneously
2~ 100g/m
2time, two-layer absorption composite bed overlaying structure effectively can prevent seepage, simultaneously according to the difference of crowd's service condition, namely menstrual period blood volume difference, the grammes per square metre of refusing water non-woven fabrics by adjustment prepares the sanitary towels of different size.It is worthy of note, when the grammes per square metre of refusing water non-woven fabrics is 20 ~ 100g/m
2time, when the external world is applied pressure increase to 3kg, adopt the also ne-leakage phenomenon generation in same test of the sanitary towel of two-layer compound absorbed layer overlaying structure in table 2, this SANITARY NAPKIN CONSTRUCTION has good leakage performance as seen.
Embodiment 4 (permeability test):
With reference to the detection method in industry standard GB/T5453-1997 " mensuration of textile fabric breathability ", permeability detection is carried out to this antiseep air permeable sanitary towel.Wherein, the grammes per square metre of refusing water non-woven fabrics absorbed in composite bed is 24g/m
2, thickness is 0.1mm.Test result is as shown in table 3 below.
Table 3:
| The number of plies (layer) of composite bed is absorbed in sanitary towel | Air penetrability (mm/s) |
| Two-layer | 3000～3800 |
| Three layers | 2500～3200 |
| Four layers | 1800～2600 |
As can be seen from Table 3, when the number of plies absorbing composite bed is 2 ~ 4 layers, permeability is good; And the increase along with the number of plies absorbing composite bed must cause the reduction of air penetrability, namely permeability reduces, and the superposition of therefore too much absorption composite bed must cause the decline of permeability.
For sanitary towel, its permeability in use is also evaluate a major criterion of sanitary towel's articles for use, carries out evaluations test the permeability in sanitary towel's use procedure of above-described embodiment 1 ~ 2.
Test method: with reference to the method for testing in embodiment 4, a white filter paper is all covered with under sanitary towel's articles for use of embodiment 1 ~ 2, then the red test liquid of 5mL and 10mL is toppled over respectively to sanitary towel's articles for use upper surface of embodiment, topple over three times altogether, two, interval 1min between each pouring liquid, wherein first 1min is without ambient pressure state, second 1min then places the object of 0.5kg respectively at sanitary towel's articles for use upper surface of embodiment 1 ~ 2, ambient pressure in simulation use procedure suffered by sanitary towel, wherein the test liquid of toppling over is be warming up to the test liquid of 80 DEG C third time.Observe the change of the white filter paper be placed on below sanitary towel, test result is as shown in table 4 below.
Table 4:
| Project | The change of white filter paper |
| Embodiment 1 | White filter paper becomes wet, but changes without color |
| Embodiment 2 | White filter paper becomes wet, but changes without color |
As shown in Table 4, because the reason of test liquid temperature difference, the white filter paper below sanitary towel becomes wet because of the steam in contact surrounding air, but not sanitary towel's seepage causes.Visible, the sanitary towel of embodiment 1 ~ 2 has good leakageresistance and permeability concurrently.
