Abstract
The utility model relates to a composite water absorption core body for hygienic products. The composite water absorption core body comprises a fabric diversion layer, an absorbing layer and a fabric separation layer, wherein the absorbing layer is arranged between the fabric diversion layer and the fabric separation layer; macromolecular water absorption resin is uniformly distributed inside the absorbing layer. The composite water absorption core body is simple in structure, reasonable in design and large in absorbing capacity, enables liquid to permeate into the composite water absorption core body quickly and completely, enables a surface layer to be kept in a drier state, and improves the comfort level of users.
Description
Technical field
This utility model relates to a kind of hygienic article, especially relates to a kind of composite water absorbing core body.
Background technology
Composite water absorbing core body of many uses, at present, the hygienic article of selling on the market, as the composite water absorbing core body of sanitary towel or diaper normally consists of Time of Fluff Slurry or non-woven fabrics, in order to improve the absorbent properties of composite water absorbing core body, people have researched and developed has increased macromolecule water uptake layer in composite water absorbing core body, but such sanitary towel or diaper are in use, and the situations such as conglomeration, fracture or clot easily occur composite water absorbing core body.This can apply a distortion action to sanitary towel or diaper while being mainly movable because of user, and composite water absorbing core body can expand after absorbing a certain amount of liquid, therefore the extruding that composite water absorbing core body various piece is born or the power of pullling can be different, thereby easily produce the situations such as the conglomeration of composite water absorbing core body, fracture or clot, to user, bring sense of discomfort; In addition; because this composite water absorbing core body is very closely knit, the absorption of liquid and the diffusion of liquid are very slow, if can not be by Liquid Absorption in the short time; can bring discomfort and trouble to user, it can absorb the requirement of large quantity of fluid at short notice can not to meet user needs.
Chinese patent 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.Synthetic fibers in innermost layer and/or the intermediate layer of absorbent cores 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.
Chinese patent CN1649554 discloses a kind of disposable absorbent article as sanitary towel, panty liners, baby diaper, adult incontinence product and antiperspirant pad.Be arranged in its lip-deep appointment towards wearer and there is a monolayer top flat for the absorbent article in the region of liquid deposition, between the operating period of goods, absorbed liquid is being positioned on this top flat.Absorbent article also comprises and forms the egative film on 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, hides the ability of the spot causing due to the liquid absorbing.This is for as especially useful in the goods of menstrual fluid or old man's urine for absorbing high color intensity.
Existingly for the composite water absorbing core body that absorbs storage of liquids, generally there is following shortcoming: the structure of composite water absorbing core body is reasonable not, the macromolecule of composite water absorbing core body is selected improper (absorbtivity is little, absorption is slow) and skewness (due to equipment performance); The intermediate layer of selecting is improper, and macromolecule cannot be entered, and diffusion is slow; The easy delamination in top layer, easily sticks together in use procedure, agglomerating, fracture and cause anxious absorption of liquid to cause the shortcomings such as side leakage.
Utility model content
The deficiency existing in order to overcome prior art, this utility model provides a kind of good absorbing effect, macromolecule water uptake core body that pipette is large.
For a composite water absorbing core body for hygienic article, described compound core body comprises fabric guide layer, absorbed layer and fabric barrier layer, and described absorbed layer is arranged between fabric guide layer and fabric barrier layer, is evenly laid with hydroscopic high-molecular resin in absorbed layer.
This utility model is provided with fabric guide layer, absorbed layer and fabric barrier layer, fabric guide layer can effectively suck liquid, absorbed layer can make liquid fast toward the infiltration of bottom direction, hydroscopic high-molecular resin layer in absorbed layer can effectively absorb storage of liquids, fabric barrier layer can avoid liquid to ooze out, by liquid lock in absorbed layer.
Preferably, described composite water absorbing core body also comprises the first hydroscopic high-molecular resin layer and the second hydroscopic high-molecular resin layer, described the first hydroscopic high-molecular resin layer is between fabric guide layer and bulk nonwoven layer, and described the second hydroscopic high-molecular resin layer is between bulk nonwoven layer and fabric barrier layer.
Preferably, all bonding by adhesive between described absorbed layer and fabric guide layer, fabric barrier layer.
Preferably, integral by sewing up between described fabric guide layer, absorbed layer, fabric barrier layer.
Preferably, described absorbed layer adopts bulk non-woven fabrics.Fabric guide layer and fabric barrier layer can be selected the various suitable fabrics of non-woven fabrics, dust-free paper, toilet paper etc.
This utility model is simple in structure, reasonable in design, and absorbtivity is large, can make liquid infiltrate in composite water absorbing core body quick and completely, and top layer is kept compared with drying regime, improves the comfort level of user.
