Description
Technical field
The present invention relates to a kind of disposable adsorption object, especially relate to and a kind of there is the disposable adsorption object improving absorbent core structures.
Background technology
The disposable adsorption objects such as existing baby paper diaper, incontinent adults's articles for use are well-known.This kind of disposable adsorption object major part all has similar structure: permeable top layer, opaque liquid bottom, and the absorbent cores between permeable top layer and opaque liquid bottom.This absorbent cores can receive and receiving fluids, as slop.Absorbent cores is usually wrapped up fluff pulp fibers by hydrophilic fibre net and is become with the mixed core system of super absorbent polymer (SAP).Permeable top layer be used for comfortable and dry and comfortable sensation is provided during Body contact, simultaneously permission liquid freely pass through, enter absorbent cores below.Opaque liquid bottom is used for absorbed liquid to retain in an absorbent core, thus prevents the clothes of absorbed fluid dirt wearer.
If the body fluid of urine is after passing through top layer, temporarily be kept in fluff pulp fibers, then by super absorbent polymer (SAP) absorb and super absorbent polymer (SAP) holds swollen, preserved by absorbed body fluid, super absorbent polymer (SAP) can increase the absorptive capacity of absorbent cores.When increasing super absorbent polymer (SAP) to improve the water absorbability of absorbing articles, or when reducing absorbent cores thus reduce the thickness of absorbing articles, just should reduce the amount of fluff pulp fibers.In the case, the fluff pulp fibers of the absorbent cores in disposable adsorption object is just relative with the ratio of super absorbent polymer (SAP) to be reduced, and the commissure between fluff pulp fibers also reduces.Consequently, disposable adsorption object is after re-absorption effect urine or menses, the volume of super absorbent polymer (SAP) increases greatly because of absorbing fluid, fiber is shorter and lose mutual cohesive force, absorbent cores there will be under the effect of pressure or shearing force that local accumulation is agglomerating and tomography situation occurs at other positions along with the motion of wearer, just lose the primary condition of logical liquid, not only have impact on the effect of absorbing fluid, also affect the comfortableness of dress.
Be in the patent of CN2323768Y at publication number, disclose a kind of graining sanitary napkins, the periphery of water suction inner core except with PUR bonding, to be fixed on leakproof counterdie upper outside for heat-sealing embossing, the centre of water suction inner core also has embossing in order to be pressed on leakproof counterdie by water suction inner core, such this utility model in use can not the group of rising, wrinkling, and towel body remains smooth, next to the skin.Be in the patent of CN2511273Y at publication number, disclose a kind of resistance to deformation, anti-breaking sanitary towel, in the middle of the absorbent material layer or between absorbent material layer and opaque liquid bottom, one deck wet-strength paper is set.Be in the patent of CN1185937A at publication number, disclose a kind of absorbing articles, it comprises a kind of liquid-keeping absorber, this absorber comprises a kind of fiber or the thin slice that are different from absorbent paper pulp fibres, this fiber or thin slice when water contacts between they itself or and other components between produce viscosity, the shape of stable absorption body thus.But above-mentioned measure, can damage the quality of absorber, make absorber become really up to the mark, nor conglomeration in absorber use procedure, breakage problem can be improved very well.
Summary of the invention
Main purpose of the present invention is the shortcoming overcoming prior art, provides a kind of and can improve the disposable adsorption object that fracture or tomography situation occur at absorbent cores local accumulation agglomerating and other positions.
Another object of the present invention is to provide a kind ofly can improve the preparation method that the disposable adsorption object of fracture or tomography situation occurs at absorbent cores local accumulation agglomerating and other positions.
According to disposable adsorption object provided by the invention, comprise permeable top layer, opaque liquid bottom and the absorbent cores between permeable top layer and opaque liquid bottom, absorbent cores comprises fluff pulp fibers and super absorbent polymer, the region that the density wherein having at least one to distribute along the longitudinal direction in absorbent cores inside is larger, described density bonds the fiber adhesive tape forming the inner genesis analysis of absorbent cores mutually by PUR compared with the fluff pulp fibers in large regions.The density of absorbent cores provided by the invention is 0.15-0.25g/cm compared with the density of large regions
3, all the other areal concentrations of absorbent cores are 0.10-0.15g/cm
3, described glue is the PUR of spiral glue or line glue form, and the region that described density is larger is 2-35mm at the width of transverse direction.Preparation method according to disposable adsorption object provided by the invention is: a, the fluff pulp fibers of pulverizing and super absorbent polymer are fully mixed post-treatment be shaped to absorptive core; B, on the core body of molding, extrude the groove extended longitudinally at least together; C, in groove, spray PUR; D, pressure roller is utilized to apply pressure to the thickness direction of absorbent cores, the fluff pulp fibers of groove both sides is made to cover described groove, form density comparatively large regions at trench region, and the PUR in primitive groove groove bonds the fluff pulp fibers contacted with it, form fiber adhesive tape; E, can with (can certainly without the coated absorbent cores of fleece) after the coated absorbent cores of fleece, absorbent cores be bonded between top layer and bottom, top layer and bottom are fixed together by bonding mode in the outside of absorbent cores and form final disposable adsorption object.
In the detailed description of the invention of the preparation method of disposable adsorption object provided by the invention, the core body of molding extrudes extend longitudinally at least together, transverse width is the groove of 2-35cm; Spiral glue spraying or line glue mode is adopted to be sprayed in groove by PUR; On the thickness direction of described absorbent cores during compacting, utilizing pressure roller mainly through applying pressure in groove both sides to absorbent cores, making the fluff pulp fibers of groove both sides and super absorbent polymer mixture cover original groove.During in the both sides of absorbent cores groove in a thickness direction to absorbent cores compacting, described pressure roller is level and smooth pressure roller or is the convex roller having bossing in the both sides relative to groove, by the bossing of level and smooth pressure roller or convex roller, groove both sides are extruded, make the fluff pulp fibers of groove both sides and super absorbent polymer cover original groove.
According to disposable adsorption object provided by the invention, by at the inner density of setting of absorbent cores comparatively large regions, density comparatively in large regions fluff pulp fibers mutually bond and form fiber adhesive tape, avoid absorbent cores local accumulation agglomerating and other positions and fracture or tomography situation occur, improve the integrity of the absorbent cores of disposable adsorption object.
