Description
Technical field
The present invention relates to a kind of to play the structure of absorption in absorbent article, can be used for paper urine more particularly to one kind
The NEW TYPE OF COMPOSITE core of absorption is played in the amenities such as trousers, sanitary napkin.
Background technique
Absorptive core in the absorbent item for nursing using very extensively, most of absorptive core or absorbed layer be by
The absorptive core of non-woven fabrics and wood pulp or Time of Fluff Slurry composition, the absorbent properties of core increase macromolecule suction in order to further increase
Water-resin SAP particle, but the product that such core is worked it out has been easy to appear the case where sticking together, being broken in use,
Simultaneously in order to guarantee assimilation effect, the product absorbing structure that this core is worked it out is usually very thick, can bring one to user
Fixed inconvenience and sense of discomfort.
It is easily risen the case where sticking together, being broken to solve core, the application for a patent for invention of Publication No. CN102715986 discloses
A kind of high-efficiency water-absorbing compound core body, the surface layer and bottom which is made of Time of Fluff Slurry or non-woven fabrics pass through sewing for diatom
The compounding substances of rock powder body and borneol powder composition are wrapped in centre, and are sewed line and are divided into multiple reticular structures.Make in this way
Core is obtained while improving absorption and diffusion velocity, does not also allow easy to knot groups, fracture or clot.
Inconvenient in order to solve core thickness bring, the application for a patent for invention of Publication No. CN101797201 discloses one kind
Polymer compound core body, the core are folder bulky nonwoven layer of cloth, bulky nonwoven cloth among dust-free paper surface layer and dust-free paper bottom
Water-absorbing resin is uniformly distributed in layer, and the dust-free paper of surface layer and bottom passes through adhesive bonds.Current this compound core body is due to can
It is widely used in ultrathin absorbent item with being arranged very thin, but this core infiltration rate and effect are weak.
Summary of the invention
That the object of the present invention is to provide a kind of absorption efficiency and infiltration rates is high, economical, does not rise and sticks together, is not broken and can basis
Need to adjust a kind of NEW TYPE OF COMPOSITE core of thickness.
In order to achieve the above object, technical scheme is as follows: a kind of NEW TYPE OF COMPOSITE core, including surface layer and centre
Layer, by adhesive bonds between surface layer and middle layer, the surface layer includes toilet paper layer and absorptive core, toilet paper layer again
It is the mixture of wood pulp and SAP with wide, described absorptive core outside absorptive core and with absorptive core, the surface layer
Width is 2-2.5 times of middle layer width, and two edge contractions on the surface layer are fully wrapped around by middle layer.
Further, the surface layer absorptive core is that 1-1.5:1 wood pulp and SAP are mixed by weight ratio.
Further, the surface layer with a thickness of 2-5mm.
As it is one of preferably, the middle core body be bulky nonwoven cloth, dust-free paper, blotting paper, hydrophilic nonwoven fabrics,
One of spunlace non-woven cloth.
As another preferred embodiment, the grammes per square metre of the middle layer is 35-80g/m2。
Alternatively preferably, the adhesive is wet strong rubber.
Preferably, the wet strong rubber coating weight is more than or equal to 3gsm.
Most preferably, the NEW TYPE OF COMPOSITE core is the suction of baby' diaper, feminine hygiene articles, adult incontinence product liner
Receive core.
Compared with the absorptive core used in the existing absorption product, the invention has the benefit that by toilet paper and wood pulp
The surface layer formed with the mixture of SAP, infiltration rate is fast, high-efficient, economical, and package is by non-woven fabrics, dust-free paper among surface layer
Or the middle layer of blotting paper composition, can effectively improve wood pulp and SAP blended absorbent core easily rise stick together, easy fracture the shortcomings that, health
Paper bag is covered sandwich layer and is bonded using wet strength agent, the Time of Fluff Slurry of sandwich layer and toilet paper it is wet strong preferably, be tightly combined, it helps increase
The intensity on surface layer is not easy to be layered, be broken；Meanwhile NEW TYPE OF COMPOSITE core of the invention, thickness can be adjusted as needed, it can
Meet different absorption products to the different demands of central absorbent core thickness, without special production equipment, surface layer package is intermediate
Layer, formed it is double-deck absorb, water absorption is big, effectively can quickly absorb and storage of urine, to use dryer and comfortableer comfortable.
