Description
Technical field
The utility model belongs to hygiene article sector, and in particular to a kind of compound core body.
Background technique
The absorptive core for the human waste treatment being currently known can substantially be divided to two kinds.One is cotton core bodies, by dust-free paper
Or hydrophilic cloth wraps up Time of Fluff Slurry and SAP(super absorbent resin) composition.Another kind is compound core body, generally dustless by outermost two layers
Paper, middle layer non-woven fabrics and two layers of SAP composition.
The Time of Fluff Slurry of cotton core body mixes SAP(super absorbent resin) it is excellent in instantaneously catching liquid ability, but it is being absorbed
Water-absorbent material is easy sliding deformation accumulation, tomography afterwards.Therefore, it was developed successively in industry at 2006 or so normal on the market at present
The compound core body seen, compound core body overcome cotton core body it is blocked up, be easy tomography, dry and comfortable poor disadvantage, realize it is ultra-thin with it is soft
It is soft.But compound core body instantaneously catches that liquid ability is poor, is from outward appearance to inner essence easy when double absorption because of the high-hydroscopicity tree after the imbibition of surface layer
Rouge generates gelatin phenomenon and blocks lower bleed-through road, double absorption leakage occurs, the overall utilization rate of core is low, and liquid is difficult to quickly
Conduction is spread to core inside and around.
Part of the manufacturer attempts the crush-cutting segmentation on compound core body and drills through core formation groove, such from top to bottom through entire
The groove of core is not significantly improved to flow conductivity, and liquid, which fails to effectively to reach core middle layer after flowing down from groove, to be expanded
Conduction is dissipated, the effect for improving core utilization rate and cross-layer conduction cannot be played, but also cause institute's open channels in process of production
The case where neighbouring water-absorbing resins largely fall.
Utility model content
In view of the above-mentioned problems, the utility model is intended to provide a kind of multiple good absorption effect, absorbs that diffusion velocity is fast, utilizes
The high compound core body of rate.
The technical solution that the utility model solves the problems, such as is: a kind of compound core body, including surface layer, bottom and be located at table
Absorbed layer between layer and bottom, the absorbed layer include at least one layer of water-absorption fiber layer, broadcast sowing in following table on water-absorption fiber layer
SAP in face and gap, is provided at least one deflector hole between surface layer and the water-absorption fiber layer of top layer, and the deflector hole will
Surface layer is run through；
At least one flow-guiding channel is equipped between bottom and undermost water-absorption fiber layer.
It is formed without SAP by controlling distributed quantity and the position of deflector hole in the deflector hole and flow-guiding channel of above scheme
It is seeped under liquid to the channel inside core, further through the distribution of flow-guiding channel, forms horizontal proliferation and the lower channel for seeping diffusion, make
Liquid, which passes rapidly through, to be entered conduction in core behind surface layer and diffuses to lower layer and horizontal proliferation, by the conduction of cross-layer layer by layer and laterally
Diffusion significantly improves multiple absorption, gas permeability and the logical fluidity of core.
Preferably, the water-absorption fiber layer is equipped at least one at least provided with two layers between adjacent two layers water-absorption fiber layer
Flow-guiding channel.The multiple absorbent properties of multilayered structure are more preferable.
Further, the water-absorption fiber layer and the intersection of deflector hole are equipped with towards the portion that arches upward of deflector hole；And/or
The intersection of the water-absorption fiber layer and flow-guiding channel is equipped with towards the portion that arches upward of flow-guiding channel；And/or
The intersection of the bottom and flow-guiding channel is equipped with towards the portion that arches upward of flow-guiding channel.
The benefit for designing the portion that arches upward is that certain separate deflector hole and flow-guiding channel can be formed to the SAP for portion two sides of arching upward
Extruding force avoids forming deflector hole and flow-guiding channel after imbibition stifled so that SAP be prevented to enter in deflector hole and flow-guiding channel
Plug.
Further, it is equipped with indent on surface layer, the deflector hole is distributed in indent.Indent structure makes surface layer, and there are one
Fixed recess, recess are not contacted between skin, are conducive to liquid flowing diffusion.
The distribution form of indent is varied, a kind of common form are as follows: the indent is in hyperbola distribution.
Preferably, each flow-guiding channel is all continuous, and it is in net that the flow-guiding channel on same plane layer, which is equipped with a plurality of,
Trellis distribution or hyperbola distribution.
Compound core body absorption pattern is changed into cross-layer by original layer-by-layer transmitting absorption from outward appearance to inner essence by the utility model
Diffusion quickly conduction absorb, the infiltration rate that liquid enters core different layers is greatly improved, significantly improve core it is multiple absorb,
Gas permeability and logical fluidity greatly improve the interim liquid storage capacity of core and the utilization rate of core.Moreover, there is no produced
The case where SAP falls in journey.
