Description
Technical field
This utility model belongs to hygiene article sector, specifically related to a kind of absorbent cores for possessing high-efficiency diversion and breathability
Body.
Background technology
The absorptive core of the human waste treatment being currently known can substantially be divided to two kinds.
One kind is compound core body, as shown in figure 1, general by outermost two-layer dust-free paper 1, middle level non-woven fabrics 2, and two-layer
SAP3（Super absorbent resin）Composition.
Another kind is cotton core body, as shown in Fig. 2 being made up of with SAP3 dust-free paper 1 or hydrophilic cloth parcel Time of Fluff Slurry 13.
In addition to above-mentioned common structure, also there is part producer to do trickle adjustment on absorbent structure, such as in the knot of Fig. 1
Add one layer of wood pulp on structure again, and emery wheel pattern pressing type is used on the cotton core body of Fig. 2.
Above-mentioned core body be after absorption of liquid plane, big with skin contact product, and the SAP that can add measures and have
Limit, adds a large amount of SAP and easily causes SAP slips and with obvious granular sensation, after imbibition core body layering will occur and slide into
Heap.
Using the product of above structure absorptive core, in actual use, there are following several drawbacks：
1. as shown in figure 1, such core body needs the usage amount by increasing PUR when needing to add a large amount of SAP, no
Then substantial amounts of SAP is easily moved, and causes skewness, and PUR excessively will result in infiltration rate obvious with breathability under
Drop, and feel is stiff.
2. as shown in Figure 1 and Figure 2, the two types core body after imbibition into plane, even if suppressing decorative pattern on core body
Also can be softened after imbibition, make product surface layer big with skin contact product, skin surface air fully cannot circulate and shape
Into convection current, the harmful gass for evaporating out, easily skin is damaged, induce various easy dermatosiss.
3., as shown in figure 1, such core body imbibition diffusion effect is weak, double absorption speed is slow, and core body utilization rate is not high.
4., as shown in Fig. 2 such core body is after SAP imbibitions, volumetric expansion, granule have mobility.Even if inhaling
Grid or striped has been suppressed on acceptor, also embossing can have been propped up after imbibition, led to not the position for fixing SAP granules.Slightly outer
In the case that power is acted on, the SAP of imbibition part is easy to shift, and causes local accumulation agglomerating and other positions generation tomography feelings
Condition, not only affects secondary imbibition effect, has an effect on the comfortableness of dress.
5., as shown in Fig. 2 such core body is typically in a large number using Time of Fluff Slurry, after imbibition, most of liquid is by Time of Fluff Slurry wink
When catch, it is difficult to two ends spread, easily cause core body local expansion heave into bag-like.In addition to tomography is easily caused, water lock loosely,
Easily cause liquid reverse osmosis, and volatile out infringement skin or impact skin feel.
Utility model content
For the problems referred to above, this utility model aims to provide one kind and can lift flow conductivity, reduction non-woven fabrics to greatest extent
Plasticizing rate, soft comfortable, the absorptive core of good permeability.
The technical scheme of this utility model solve problem is：A kind of absorptive core for possessing high-efficiency diversion and breathability,
Absorbed layer including top layer, bottom and between top layer and bottom, the absorbed layer include the nothing that fits with top layer lower surface
Layer of cloth is spun, uniform broadcasting in nonwoven layer has super absorbent resin；
The top layer fits to form composite bed with nonwoven layer, and composite bed is provided with diversion channel slot, and the diversion channel slot is by core
Body is divided into polylith absorption region；
Composite bed with diversion channel slot is connected with bottom upper surface；
Uniform broadcasting between nonwoven layer lower surface and bottom upper surface has super absorbent resin.
Current flattened absorbent core body is improved to cubic absorption core body by such scheme, is divided into core body using diversion channel slot
Polylith, expansion after first time imbibition form mountain peak shape, and during second imbibition, liquid is down led under gravitional force effect naturally
Stream, accelerates liquid conductive absorption, effectively raises double absorption speed.The higher projection formed after imbibition reduces face
Layer and the contact area of skin, improve breathability.
Can exactly allow SAP to be located in a relative narrow space another benefit that core body is divided into polylith, prevent
SAP is shifted.Allow to not in a large number using PUR in the case of add more SAP, and without granular sensation.
Add more SAP between nonwoven layer lower surface and bottom upper surface, be conducive to the multiple absorption of liquid core.
Further, the nonwoven layer includes the first nonwoven layer and the second nothing below the first nonwoven layer
Layer of cloth is spun, uniform broadcasting in the first nonwoven layer has the first super absorbent resin, uniform broadcasting in the second nonwoven layer to have second
Super absorbent resin, uniform broadcasting between the second nonwoven layer lower surface and bottom have the 3rd super absorbent resin；
Air duct is formed between first nonwoven layer and the second nonwoven layer.
Before not having imbibition, air duct plays air circulation and dresses not vexed effect, can be supplied to SAP enough after imbibition
Expansion space.
Preferably, the first, second, third super absorbent resin model is different, first, second, third high-hydroscopicity
Resin rate of liquid aspiration gradually strengthens successively, constitutes rate of liquid aspiration gradient difference from slow to fast from top to bottom.The different model
SAP point of paved in multi-layers, reduces SAP because of mobile produced granular sensation in heaps, SAP can be selected to be spread according to the characteristic of SAP
The position that puts and consumption, to adjust the infiltration rate of core body, dry-ness etc. as needed, enhance designing for core body performance
Property.So as to improve the overall utilization rate of core body, and the infiltration rate and multiple imbibition effect of core body have been obviously improved it.
Specifically, diversion channel slot is S-shaped or linear.
The mode that the top layer is fitted with nonwoven layer is hot rolling, ultrasonic bonds, linear slit, the one kind or several in glue bond
Kind.
Between the composite bed and bottom with diversion channel slot, connected mode is glue bond.
The diversion channel slot is made using heat bonding.
Remarkable result of the present utility model is：
1. core body does not have top layer, nonwoven layer and bottom together heat bonding, but is first combined between the layer of part, can
Reduce non-woven fabrics plasticizing rate to greatest extent, increase soft comfortable degree, improve sense of touch.
2. the design of flow guiding type groove, can form stable air duct in core surface, accelerate liquid fast along passage
Speed diffusion, while improve the overall utilization rate of core body.
3.SAP point of multilamellar blanking, is substantially improved the admissibility of core body, and mid portion material adopts gluing-free work
Skill, is decreased obviously core body entirety resin added and is more beneficial for oozing under liquid, be effectively improved infiltration rate.
4. the SAP layering blankings in core body cause collocation form variation, can be from the full water yield, logical fluidity, reverse osmosis amount etc.
Each side carry out the model and applied amount of each layer SAP of comprehensive Design, are greatly improved the designability of core body performance.
5. core body does not use Time of Fluff Slurry, and most of liquid was absorbed by SAP in the incipient stage, small part by fabric nonwoven cloth or
Dry-papermaking is kept in, and is then all absorbed by SAP and is locked.The harmful gass that can be evaporated, major part can be passed through ventilative thin
Film and bottom non-woven fabrics outwards volatilize, from absorb surface layer evaporate very little, the infringement that skin is caused is reduced to
Minimum level.
