Abstract
The utility model provides a compound water-absorbing core body which comprises a first dust-free paper layer on the upper layer of the core body, a non-woven fabric layer in the middle layer of the core body and a second dust-free paper layer on the lower layer of the core body. Macromolecule water-absorbing particles are distributed in the non-woven fabric layer, and more than one diversion trough communicated vertically is formed in the non-woven fabric layer. When the absorbent paper is used, liquid can be absorbed along gaps in short time and quickly spread around, so the liquid can not be gathered in the center of the absorbent paper, the water-absorbing area is enlarged, and water-absorbing properties and water-absorbing capacity are improved greatly.
Description
Technical field
This utility model relates to a kind of paper, especially relates to a kind of composite water absorbing core body.
Background technology
At present, the sanitary towel of selling on the market or absorptive core or the absorbed layer of diaper are all to consist of Time of Fluff Slurry or non-woven fabrics conventionally, in order to improve the absorbent properties of absorptive core or absorbed layer, people have researched and developed has increased macromolecule water uptake layer in absorptive core, but such sanitary towel or diaper are in use, easily there is the situation of conglomeration, fracture or clot in absorptive core or absorbed layer.This is mainly the distortion action that applies due to the movable Shi Huidui sanitary towel of user or diaper, and absorptive core can expand after absorbing a large amount of liquid, therefore the extruding that absorptive core various piece is born or the power of pullling can be different, thereby easily produce the situation ，Gei sanitary towel of absorptive core conglomeration, fracture or clot or the user of diaper and bring sense of discomfort; In addition due to very closely knit of this absorptive core; the absorption of liquid and the diffusion of liquid are very slow; this is a great problem for requiring at short notice sanitary towel or the diaper of the large quantity of fluid of absorption; if because Liquid Absorption just easily can not be caused to fluid seepage in the short time, made troubles to user.
Chinese patent CN2467322 discloses a kind of water absorbent composite paper pad, accompanies the fluff pulp fibers layer that is mixed with polymeric particles between two fabric layers.
Chinese patent CN95217890 discloses a kind of high molecular water absorption composite paper, and paper using or fabric are made surface layer and bottom, and therebetween one deck adds or do not add the water-absorbing resin layer of the wood fiber, by glue laminated, closes and has adhesive layer.Its common deficiency is: the fiber species of surface layer, bottom, sandwich layer is single, all adopt the single wood fiber, thereby pull resistance is poor; And the existence of glue-line can reduce water absorption and the fiber bulkiness of paper greatly.
Chinese patent CN2614660 discloses a kind of absorbent dustless paper, and by fibrous surface layer, the superimposed shaping of sandwich layer and bottom, has water-absorbing resin in sandwich layer fibrous layer, it is characterized in that in surface layer, sandwich layer and bottom that at least one deck is mixed fiber layer.
Existing composite absorbent paper, owing to being planar structure, is unfavorable for liquid diffusion, when water flows in absorbent paper, conventionally can be gathered in center and indiffusion, easily causes the allergy of infant skin; And the absorbent paper at two ends does not use at all, also caused wastage of material.
Summary of the invention
This utility model will solve the deficiency in above-mentioned technology, proposes a kind of new composite absorbent paper, thereby improves the water-taking efficiency of absorbent paper.
The technical solution of the utility model: a kind of composite water absorbing core body, described water suction core body comprises and is positioned at the first dustless ply of paper on upper strata, the second dustless ply of paper that is positioned at the nonwoven layer in intermediate layer and is positioned at lower floor, in described nonwoven layer, be distributed with water absorbing polymer particle, described nonwoven layer is provided with the curb of one or more up/down perforation.
As preferably, on the first described dustless ply of paper and the second dustless ply of paper, be also provided with the curb of one or more up/down perforation.
As preferably, the curb arranging in the curb arranging on the curb arranging on described the first dustless ply of paper, the second dustless ply of paper and nonwoven layer is communicated with up and down.
As preferably, the curb arranging in the curb arranging on the curb arranging on described the first dustless ply of paper, the second dustless ply of paper and nonwoven layer is more than three.
As preferably, described each curb is parallel to each other and is uniformly distributed, described curb be shaped as straight line or curve.
As preferably, the width of described curb is 0.1～2mm.
As preferably, the spacing of described adjacent curb is 0.5～3cm.
As preferably, the length of described curb is no more than 90% of water-absorbing core body length.
When absorbent paper of the present utility model is used, liquid can flow to core body two ends fast along curb, and is diffused into rapidly surrounding, can by core body, be absorbed at short notice, be not gathered in absorbent paper center, expanded water suction area, greatly improved water absorbing properties and water absorption capacity; And because liquid is evenly absorbed, be conducive to the dry and comfortable of user skin.
