Description
Technical field
The utility model relates to paper diaper field more particularly to a kind of through-hole type cores.
Background technique
In disposable sanitary articles field, there are two types of forms for the production of common product core, first, using dustless paper wood
Material is used as core, and such production method dust-free paper material cost is high, and dustless paper material has high molecular material in operation
In addition the phenomenon that being scattered need to match a set of dust accumulation equipment；Second, after being crushed using wood pulp paper by pulverizer, in forming bin with height
Molecular material is mixed to form, and is molded into core through template.Second of production method, core cotton core amount is determined according to template thickness
's.Phenomena such as thickening formwork core body and thickeing can make product airtight, and user can generate red hip, and it is easy to produce tomography；
Template is thinned, then core amount is reduced, and it is bad to have an assimilation effect, phenomena such as leading to liquid side leakage reverse osmosis.
China Patent No.: 201220345744.3 disclose a kind of absorptive core suitable for paper diaper sanitary napkin, are equipped with
Non-woven fabrics surface layer, bottom layer of non-woven fabrics and bulky nonwoven layer of cloth, bulky nonwoven layer of cloth be set to non-woven fabrics surface layer and bottom layer of non-woven fabrics it
Between and with non-woven fabrics surface layer and bottom layer of non-woven fabrics hot pressing composite joint, the surface of the non-woven fabrics surface layer and bottom layer of non-woven fabrics is equal
With embossing, water-absorbing resin is uniformly impregnated in bulky nonwoven layer of cloth, absorptive core is equipped with the water suction through-hole battle array in impenetrating thickness direction
Column.The absorptive core by adopting the above technical scheme, by be equipped with impenetrating thickness direction water suction through-hole array, when in use, together
Under sample dimensions, the water absorption rate of the absorptive core can be dramatically increased, and correspondingly returning infiltration rate can significantly reduce；Air penetrability is also significant
It improves；But the water suction through-hole array for absorbing water and breathing freely is set, and when the diameter setting for the through-hole that absorbs water is smaller, absorptive core
Water absorbing properties and permeability effect it is bad；When the diameter setting of water suction through-hole is larger, in the technique of manufacture water suction through-hole,
Water-absorbing resin in bulky nonwoven cloth can walk, and cause the bulk rear cotton core agglomeration dislocation that absorbs water, lower comfort.
Utility model content
Therefore, for above-mentioned problem, the utility model provides a kind of through-hole type core, it mainly solves the prior art
The problem of water imbibition, poor air permeability of middle core, the bulk rear agglomeration that absorbs water misplaces.
To achieve the above object, the utility model uses following technical scheme: a kind of through-hole type core, including absorbent cores
And the hydrophilic nonwoven fabrics in absorbent cores are coated on, it is provided between the upper and lower surfaces and hydrophilic nonwoven fabrics of the absorbent cores
Glue layer, the absorbent cores include the first absorptive core, the second absorptive core and the upper surface that the first absorptive core is arranged in
With the pervious bed on the lower surface of the second absorptive core, several through-holes, the diameter of the through-hole are provided in the absorbent cores
For 3mm~6mm, a plurality of hot-pressing points are provided in the absorbent cores.
Further, the diameter of the through-hole is 4mm.
Further, the hot-pressing point is distributed in matrix, and the distance of adjacent two hot-pressing point is 10.5mm, the hot-pressing point
Diameter be 1.5mm.
Further, the pervious bed is non-woven fabrics or toilet paper.
Further, first absorptive core and the second absorptive core are wood pulp layer, are uniformly divided on the wood pulp layer
Cloth is provided with sap high molecular material.
By using preceding solution, the beneficial effects of the utility model are: this through-hole type core, passes through setting first
Absorptive core and the second absorptive core, sufficiently improve the uptake of absorbent cores, and it is existing effectively to prevent absorbent cores from generating tomography
As；The through-hole for forming hollow out by removing material in absorbent cores, the effective infiltration rate for improving absorbent cores and control urine are anti-
It seeps, increases permeability, and the sap high molecular material in absorbent cores absorbs after urine expands and is diffused into through hole, prevents sap
Assemble after high molecular material expansion, improves the soft comfortable of absorbent cores；Between the upper and lower surfaces and hydrophilic nonwoven fabrics of absorbent cores
The glue layer being respectively provided with avoids the sap high molecular material of through hole from falling off, guarantees the integrality of absorbent cores；It is located in absorbent cores
Hot-pressing point, after avoiding absorbent cores from absorbing liquid expansion, sap high molecular material conglomeration dislocation, and there are certain guide functions,
Improve the comfort level of user.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment；
Fig. 2 is the overlooking structure diagram of absorbent cores in the utility model embodiment.
Specific embodiment
Now in conjunction with the drawings and specific embodiments, the present invention will be further described.
The utility model embodiment are as follows:
With reference to Fig. 1 and Fig. 2, a kind of through-hole type core, including absorbent cores 1 and the hydrophilic nonwoven being coated in absorbent cores 1
