Understandable, the shape that main uptake zone 11 on described top flat 10 and time uptake zone 12 are arranged is not limited to the shape shown in Fig. 1, Fig. 3, Fig. 4 and Fig. 5, in other embodiments, described main uptake zone 11 and time uptake zone 12 can also be designed to other various rules or irregular shape, such as described main uptake zone 11 and time uptake zone 12 can be arranged respectively to rectangle and oval, both are all set to rectangle or both are all set to oval etc., or described main uptake zone 11 and time uptake zone 12 is asymmetric the various shape such as to arrange.
Described main uptake zone 11 discharges the region that position directly contacts, the body fluid entering this region is more, in order to ensure user dry and comfortable comfort in use, the material requirement of this main uptake zone 11 has can rapid osmotic body fluid properties.
Described uptake zone 12 does further osmotic absorption to the liquid outside main uptake zone 11, play leak-proof reinforced, the material of this uptake zone 12 requires to have the performance permeating body fluid, because body fluid pervious is to amount the lacking compared to main uptake zone 11 of described uptake zone 12, so this uptake zone 12 is selected compared to the more weak material of the permeance property of main uptake zone.
Usual body fluid is discharged and is fallen into after in described main uptake zone 11, most body fluid all can rapid osmotic be sponged by absorber to this region, small part not to be entered in time region, uptake zone 12 by the body fluid that main uptake zone 11 osmotic absorption is fallen and is fallen by osmotic absorption, and the body fluid that can enter in described comfort zone 13 is few, therefore described comfort zone 13 is selected compared to the weak material of the permeance property of secondary uptake zone 12, and the skin of most of region conforms user in this comfort zone 13, so the material of this uptake zone 12 also requires to have smoothly, low friction sense, feel to provide user soft comfortable.
To sum up, to meet the consumer i.e. dry and comfortable but also demand of the absorbent article 100 of soft comfortable, the requirement of the material of the regional that the top flat 10 of described absorbent article 100 divides will be different.So according to top flat 10 divide regional to the different requirements of material, the zones of different of this top flat 10 is done different designs to meet the different demands of user, that is, described top flat 10 is designed to be followed successively by main uptake zone 11, secondary uptake zone 12, comfort zone 13 to the permeability of liquid is descending.
In order to further meet the demand of the dry and comfortable soft comfortable of absorbent article, regional on top flat 10 can be controlled the rate of oozing is returned to body fluid.According to the different demands of regional, described top flat 10 is designed to return that the rate of oozing is ascending is followed successively by main uptake zone 11, secondary uptake zone 12, comfort zone 13 to liquid.
In prior art, the material of top flat 10 mainly contains two kinds, i.e. PE making hole film and non-woven fabrics.Come to be that the trizonal different demand how realized on described top flat 10 is described with these two kinds of materials below.
The first material: the material of described top flat 10 selects PE making hole film.
Described PE making hole film is provided with through hole.Described through hole has upper end towards skin surface and the lower end towards absorber 20 relative with upper end.
Because the number of openings of the setting in certain region on top flat 10 is more, the total pore volume in this region is larger, its ratio accounting for the cumulative volume in this region is larger, namely the porosity in this region is larger, larger to the permeability of liquid, so the different requirements in order to meet each region, the through hole porosity on described top flat 10 is descending is followed successively by main uptake zone 11, secondary uptake zone 12, comfort zone 13.Preferably, the through hole porosity of described main uptake zone 11 is 2 ~ 5 times of the through hole porosity of time uptake zone 12, and the through hole porosity of described uptake zone 12 is 2 ~ 5 times of the through hole porosity of comfort zone 13.
Because aperture, through hole upper end is larger, the speed of osmotic absorption liquid is faster, permeability is larger, so the different requirements in order to meet each region, on described top flat 10, the via design in 3 regions becomes that aperture, upper end is descending is followed successively by main uptake zone 11, secondary uptake zone 12, comfort zone 13.
Through hole on described top flat 10 is preferably set to " V " shape, and namely the aperture, upper end of described through hole is greater than aperture, described lower end.When body fluid is discharged on described top flat 10, because the aperture, upper end towards skin surface is comparatively large, the speed that body fluid pervious enters top flat 10 is relatively very fast, and because of the aperture, lower end towards absorber 20 less, it is surperficial that the body fluid entering into top flat 10 is not easy the reverse osmosis sheet 10 that returns back to top.
When the material of described top flat 10 is PE making hole film, meet the absorbent article 100 i.e. demand of dry and comfortable soft comfortable again by adopting different punching forms in the zones of different of described top flat 10.In three regions, described main uptake zone 11 directly directly contacts with the body fluid outlet of human body, this region needs the ability of rapid osmotic liquid, so this main uptake zone 11 adopts the punching form in maximum porosity and maximum aperture, upper end to meet the demand of this region rapid osmotic liquid; Described time uptake zone 12 is to the unabsorbed body fluid in main uptake zone 11 osmotic absorption further, the body fluid volume of the relatively main uptake zone 11 of body fluid volume is less, so this uptake zone 12 adopts than the relatively little punching form of the porosity of main uptake zone 11 and aperture, upper end to meet the demand of the further permeation liquid in this region; Described comfort zone 13 requires to have smoothly, the material of the permeable body fluid of low friction sense, so this region adopts the transparent liquid performance meeting low quantity of fluid than the relatively little punching form of the porosity of secondary uptake zone 12 and aperture, upper end, and local eminence around hole is caused because punching in this region, the area making this region contact skin reduces relatively, the phenomenon of chafing against skin also just reduces relatively, meets the demand of comfort level.In addition, the through hole on described top flat 10 is set to " V " shape, can reduce the body fluid entering into absorber 20 and again return the phenomenon generation of oozing sheet 10 surface that returns back to top, further make this absorbent article reach dry and comfortable effect comfortable again.
The second material: the material of described top flat 10 selects non-woven fabrics.
Because fiber is thicker, its to the transient absorption power of body fluid and liquid storage amount larger, Test Liquid Permeability of Core is larger, otherwise fiber is thinner, what show is more soft, so 3 region differences according to demand of described top flat 10 are designed to different fibre coarsenesses, namely the fibre coarseness of described main uptake zone 11 is maximum, next is time uptake zone 12, and what fibre coarseness was minimum is comfort zone 13.
Because fibrous layer is thicker, body fluid and the liquid storage amount of absorption are larger, fibrous layer is thinner, show more comfortable, so 3 region differences according to demand of described top flat 10 are designed to different fiber thickness, namely the fiber thickness of described main uptake zone 11 is maximum, and be secondly time uptake zone 12, the thinnest is comfort zone 13.
Because fibre density is looser, fiber absorber 20 liquid is more smooth and easy, the speed of the infiltration of body fluid is faster, fibre density is tightr, shows more smooth, has relatively low friction sense, so 3 region differences according to demand of described top flat 10 are designed to different fibre densities, namely the fibre density of described comfort zone 13 is maximum, and being secondly time uptake zone 12, is finally main uptake zone 11.
When the material of described top flat 10 is non-woven fabrics, meet the absorbent article 100 i.e. demand of dry and comfortable soft comfortable again by adopting different fibre coarseness, fiber layer thickness and fibre density in the zones of different of described top flat 10.When three regions of described top flat 10 adopt the material of different fibre coarseness, the main uptake zone 11 that fiber is the thickest has the fastest body fluid absorption power and maximum liquid storage amount, meets the maximum body fluid real permeability needed for this zone material; The material that fiber is the thinnest is selected in comfort zone 13, embodiment be the most soft sense of touch, meet the soft requirement of pro-skin needed for this zone material; The fibre coarseness of secondary uptake zone 12 is selected between main uptake zone 11 and comfort zone 13, meets the requirement of the further osmotic absorption body fluid in this region.
When three regions of described top flat 10 adopt the material of different fiber layer thickness, the main uptake zone 11 that fibrous layer is the thickest has maximum liquid storage amount, meets the requirement of the maximum permeability of these region needs; Comfort zone 13 adopts the material that fibrous layer is the thinnest, and this region is the most comfortable, meets the requirement that this region pro-skin is comfortable; The fiber layer thickness of secondary uptake zone 12 is selected between main uptake zone 11 and comfort zone 13, meets the requirement of the further osmotic absorption body fluid in this region.Further, if do punching design at regional, then the through hole that the main uptake zone 11 that fibrous layer is last is formed is the darkest, and the body fluid through absorbing the most not easily returns and oozes, and meets the minimum requirement returning the rate of oozing of these region needs.
When three regions of described top flat 10 adopt the material of different fibre density, it is the most smooth and easy that the main uptake zone 11 that fibre density is the loosest absorbs body fluid, and body fluid pervious is fastest, and permeability is maximum; Fibre density the most closely comfort zone 13 is the most smooth because its fiber interweaving the most closely shows this region surface, and minimum friction is felt, and meets the requirement that pro-skin needed for this region is comfortable; The fibre density of secondary uptake zone 12, between main uptake zone 11 and comfort zone 13, meets the requirement of the further osmotic absorption body fluid in this region.
Certainly, the non-woven fabrics of above-mentioned three kinds of unlike materials can be together with each other, and makes it the different requirements more meeting each region.Namely, in three regions, described main uptake zone 11 adopts the non-woven fabrics that fibrous layer is the thickest, fibre coarseness is the thickest and fibre density is the loosest, can have the highest permeability, meet the performance of described main uptake zone 11 needs rapid osmotic liquid; Described comfort zone 13 adopts the non-woven fabrics that fibrous layer is the thinnest, fibre coarseness is the thinnest and fibre density is the finest and close, can meet the level and smooth of these comfort zone 13 needs, the requirement of the liquid permeable of low friction sense; The fiber layer thickness that described uptake zone 12 adopts, fibre coarseness and fibre density all between main uptake zone 11 and comfort zone 13, to meet the demand of time uptake zone 12 osmotic absorption body fluid further.
Understandable, in order to improve the infiltration rate of non-woven fabrics material to liquid, punching design can be done on non-woven fabrics.Due to the easy reverse osmosis liquid of non-woven fabrics material, and have the body fluid of non-woven fabrics of punching design to return the rate of oozing to be greater than and to return without punching design non-woven fabrics the rate of oozing, think that balance non-woven fabrics is to the infiltration rate of liquid and return the rate of oozing, preferably, non-woven fabrics carries out the punching design of low porosity.
Understandable, in order to the present position that consumer can be allowed from the transparent liquid face of the top flat 10 of absorbent article 100 easily to pick out zones of different this top flat 10, different colours can be arranged to distinguish in the main uptake zone 11 that the top flat 10 of this absorbent article 100 comprises, secondary uptake zone 12 and comfort zone 13.
Absorbent article provided by the present invention, be characterized according to the instructions for use of user to the zones of different of absorbent article, described top flat 10 is marked off main uptake zone 11, secondary uptake zone 12 and comfort zone 13, and makes different designs for top flat 10 material of difference to absorbent article of the instructions for use of zones of different.Compared with the absorbent article of prior art, absorbent article provided by the invention can meet the not only dry and comfortable but also requirement of soft comfortable simultaneously.
