Description
Technical field
This utility model belongs to hygienic article technical field, specifically relates to a kind of composite water absorbing core body.
Background technology
Water-absorption core body is one of main material manufacturing the hygienic article such as sanitary towel, diaper, diaper, protective pad.At present, the sanitary towel of commercial type or the Water-absorption core body of diaper or absorbed layer are all be made up of Time of Fluff Slurry or non-woven fabrics usually, in order to improve the absorbent properties of Water-absorption core body or absorbed layer, people add macromolecule water uptake layer in Water-absorption core body, but such sanitary towel or diaper are in use, easily there is the situation of conglomeration, fracture or clot in Water-absorption core body or absorbed layer.This is mainly due to can to applying distortion action of sanitary towel or diaper during resource-user cost method, and Water-absorption core body can expand after absorbing a large amount of liquid, therefore the extruding of bearing of Water-absorption core body various piece or power of pullling can be different, thus easily produce the situation of Water-absorption core body conglomeration, fracture or clot, bring sense of discomfort to the user of sanitary towel or diaper; In addition due to this Water-absorption core body very closely knit; the absorption of liquid and the diffusion of liquid are slowly; this is a great problem for requiring to absorb the sanitary towel of large quantity of fluid or diaper at short notice; if because Liquid Absorption just easily can not be caused fluid seepage in the short time, made troubles to user.
Chinese patent CN 2225487 discloses a kind of high molecular water absorption composite paper, and paper using or fabric make surface layer and bottom, and therebetween one deck adds or do not add the water-absorbing resin layer of the wood fiber, closes and there is adhesive layer by glue laminated.Its weak point is: the fiber species of surface layer, bottom, sandwich layer is single, and all adopt the single wood fiber, thus pull resistance is poor; And the existence of glue-line can reduce water absorption and the fiber bulkiness of paper greatly.
Chinese patent CN 101797201A discloses one and is mainly used in the paper napkin and diaper, can not realize sticking together, not rupture, the polymer compound core body of not delamination and preparation method thereof.Polymer compound core body is provided with dust-free paper top layer, dust-free paper bottom and bulky nonwoven layer of cloth, bulky nonwoven layer of cloth to be located between dust-free paper top layer and dust-free paper bottom and to be gluedd joint with dust-free paper top layer and dust-free paper bottom adhesive, is evenly impregnated with water-absorbing resin in bulky nonwoven layer of cloth.Its weak point is: (1) dustless ply of paper aperture is larger, hydroscopic high-molecular resin is easily run out, and makes human allergy, and the hydroscopic high-molecular resin on (2) non-woven fabrics is evenly distributed in non-woven fabrics, the lock outlet capacity of hydroscopic high-molecular resin cannot be played completely, easily cause waste.
Utility model content
In order to overcome the deficiency that prior art exists, this utility model provide a kind ofly not rupture, safety is good, water absorption is strong, water-retaining property is good composite water absorbing core body.
A kind of composite water absorbing core body, comprise surface layer, sandwich layer and bottom, the second articulamentum that described sandwich layer from bottom to top comprises the first articulamentum be made up of the wood pulp cellulose containing powdery hot-melt glue or ES fiber, the first water accepting layer be made up of water absorbing polymer particle, the enhancement layer be made up of long fibre bulky nonwoven cloth, the second water accepting layer be made up of water absorbing polymer particle in turn and is made up of the wood pulp cellulose containing powdery hot-melt glue or ES fiber, evenly be impregnated with water absorbing polymer particle in described first articulamentum, in described enhancement layer, be also evenly impregnated with water absorbing polymer particle.
First articulamentum of the present utility model, the second articulamentum are made up of the wood pulp cellulose containing powdery hot-melt glue or ES fiber respectively, integral adhesive effect can be played after the heating, need not carry out bonding additionally by adhesive again, water absorbing properties can not be affected, in addition, wood pulp can also play the effect increasing absorption speed; Enhancement layer is made up of long fibre bulky nonwoven cloth, can play locking water absorbing polymer particle and increase the effect of pulling force, and the urine pants diaper etc. making it manufacture to obtain can not rupture.
As preferably, described composite water absorbing core body is provided with one or more from top to bottom through baffle, and described baffle is linear or shaped form.Liquid along curb fast to the flowing of core body two ends, and can be diffused into surrounding rapidly, can be absorbed at short notice, not be gathered in absorbent paper center, expand water suction area, substantially increase water absorbing properties and water absorption capacity by core body.
As preferably, described baffle quantity is three, and upper and lower two baffles are linear and arrange in horizontal parallel, and a baffle between upper and lower two baffles is that shaped form is arranged.This structure can effectively increase its guide functions, liquid can be absorbed sooner, improve its water absorbing properties and water absorption capacity.
As preferably, the fibre length of described long fibre bulky nonwoven cloth is 52 ~ 64mm.Fibre length has a great impact for the intensity of non-woven fabrics, and the present invention finds when testing, and within the specific limits, the tensile property of non-woven fabrics can increase along with the increase of fibre length, but when exceeding certain length, tensile property can decline.
As preferably, described surface layer adopts dust-free paper, and bottom adopts nonwoven fabric of long fibers.
As preferably, the fibre length of described nonwoven fabric of long fibers is 55 ~ 60mm.Carry out bottom non-woven fabrics select test time, find equally, within the specific limits, the tensile property of non-woven fabrics can increase along with the increase of fibre length, but when exceeding certain length, tensile property can decline.
This utility model water absorbing polymer particle is not easily run out of, safety is good; A water absorbing polymer particle part evenly infiltrates the first articulamentum or enhancement layer, and another part forms macromolecule water uptake layer, can reach that absorption speed is fast, absorbtivity large and the object of good water-retaining property, makes it keep dry condition; Simultaneously due to the existence of enhancement layer, the intensity of Water-absorption core body can being increased, can not rupture due to distortion action when sucking Large Copacity liquid.This utility model have do not rupture, safety is good, water absorption is strong, water-retaining property is good, production operation is simple, low cost and other advantages.
