Background technology
At present, work the absorptive core that absorbs the effect of storage urine for hygienic article such as the paper napkin, diaper and be generally the macromolecule absorptive core, existing some shortcomings that still exist.As: infiltration rate is slow, water absorption rate is lower, the core body breathability is not good enough, and generally all need to use gluing, the feature of environmental protection is not good enough etc.
Publication number is that the application for a patent for invention of CN1658810 discloses a kind of multilayer absorbent core, and this absorbent cores contains synthetic fibers, to improve the liquid transfer performance of obtained absorbent article.The innermost layer of absorbent cores and/or the synthetic fibers in the intermediate layer have especially improved the rewetting performance of absorbing products.Described absorbent cores can join in many absorbent articles, comprises diaper, feminine hygiene and incontinence pad.
Publication number is that the application for a patent for invention of CN1649554 discloses a kind of disposable absorbent article such as sanitary towel, panty liners, baby diaper, adult incontinence product and antiperspirant pad.Be arranged in it and have a monolayer top flat towards the absorbent article that lip-deep appointment of wearer is used for the zone of liquid deposition, between the operating period of goods absorbed liquid is being positioned on this top flat.Absorbent article also comprises the egative film on formation liquid obscures surface and the one absorbent cores between top flat and egative film.Described one core has improved the liquid handling capacity of absorbent article and has strengthened the screening effect of goods, namely hides the ability of the spot that causes owing to the liquid that absorbs.This is for especially useful for the goods of the urine that absorbs high color intensity such as menstrual fluid or old man.
Publication number is that the application for a patent for invention of CN101797201A discloses a kind of macromolecule absorptive core and preparation method thereof, relates to a kind of macromolecule absorptive core.A kind of paper napkin and diaper of being mainly used in is provided, can not realize sticking together, do not rupture, the macromolecule absorptive core of not delamination and preparation method thereof.The macromolecule absorptive core is provided with dust-free paper top layer, dust-free paper bottom and bulk nonwoven layer, bulk nonwoven layer is located between dust-free paper top layer and the dust-free paper bottom and with dust-free paper top layer and dust-free paper bottom adhesive and is gluedd joint, and evenly is impregnated with water-absorbing resin in the bulk nonwoven layer.Urine can infiltrate in the macromolecule absorptive core quick and completely, the dust-free paper top layer of absorptive core can effectively suck urine, the hydroscopic high-molecular resin layer of macromolecule absorptive core can effectively absorb the storage urine, bulk nonwoven layer can make urine fast toward the infiltration of bottom direction, therefore water absorption is large, and surface layer is kept than drying regime, make human body comfortable.
Summary of the invention
Main purpose of the present utility model provides a kind of absorptive core that is applicable to diaper sanitary towel that can obviously improve absorption speed, water absorption rate and breathability.
This utility model is provided with non-woven fabrics top layer, bottom layer of non-woven fabrics and bulk nonwoven layer, bulk nonwoven layer be located between non-woven fabrics top layer and the bottom layer of non-woven fabrics and with non-woven fabrics top layer and bottom layer of non-woven fabrics hot pressing composite joint, the surface of described non-woven fabrics top layer and bottom layer of non-woven fabrics is all with embossing, evenly be impregnated with water-absorbing resin in the bulk nonwoven layer, absorptive core is provided with the suction via-hole array of impenetrating thickness direction.
The shape of described absorptive core is preferably rectangle or square etc.
Described water-absorbing resin can adopt super absorbent resin or High hydrophilous resin (Super Absorbent Polymer, SAP) etc.; Described bulk nonwoven layer is preferably the bulk non-woven fabrics of long fine water conservancy diversion.
Described embossing is preferably the concave point array.
The aperture of each through hole of described suction via-hole array can be 1～5mm.
Compared with the prior art, the utlity model has following outstanding advantages:
During application, this utility model is as the absorptive core of the hygienic article such as diaper, sanitary towel.Because absorptive core adopts technique scheme, especially be provided with the suction via-hole array of impenetrating thickness direction, when therefore using, under the same size specification, the water absorption rate of absorptive core of the present utility model can significantly increase (increasing by 20%～30%), correspondingly returns the rate of oozing and can significantly reduce; Air penetrability can significantly improve (improving 20%～30%).In addition, absorptive core all adopts nonwoven cloth material, does not contain glue, does not contain wood pulp cellulose, therefore more environmental protection.
Description of drawings
Fig. 1 is the structural representation (cross-sectional structure) of this utility model embodiment.
Fig. 2 is the preparation process schematic diagram of this utility model embodiment.
The specific embodiment
Referring to Fig. 1, absorptive core is provided with non-woven fabrics top layer 1, bottom layer of non-woven fabrics 2 and bulk nonwoven layer 3.Bulk nonwoven layer 3 be located between non-woven fabrics top layer 1 and the bottom layer of non-woven fabrics 2 and with non-woven fabrics top layer 1 and bottom layer of non-woven fabrics 2 hot pressing composite joints, bulk nonwoven layer 3 interior super absorbent resin (or the hydroscopic high-molecular resins that evenly are impregnated with, Super Absorbent Polymer, SAP) (shown in pit among Fig. 1), absorptive core is provided with suction through hole 4 arrays at thickness direction.The aperture of each through hole 4 that absorbs water is that 3mm(can be 1～5mm).
Described bulk nonwoven layer 3 is the bulk non-woven fabrics of long fine water conservancy diversion.
