Description
Technical field
The invention belongs to disposable sanitary articles field, especially relate to a kind of composite absorbent paper macromolecule adding set.
Background technology
Diaper core body, it is the core ensureing water suction lock water function, conventional paper urine pants core body, with macromolecule water absorbent material and wood pulp mixing, through wet-strength paper or hydrophilic spunbond non-weaving cloth is coated forms, cotton core absorbed thickness is thicker, and such material and structure, after water suction, moisture is easily deposited in water filling position and not easily spreads, due to the impact of gel blocking, macromolecule water absorbent material utilization rate is low, also there is certain limitation in lock outlet capacity, simultaneously, because this material-structure is more open, once water suction, will the group of rising, tomography, through motion extruding, often unavoidablely there is deformation of core.Along with the progress of manufacturing process, by improving the mode that macromolecule water absorbent material mixes with wood pulp, ladder powder type is formed from sandwich structure and Homogeneous phase mixing structural development, namely along absorptive core thickness direction, macromolecule water absorbent material is different from wood pulp ratio, upper strata is macromolecule water absorbent material and more wood pulp, and middle level is macromolecule water absorbent material and less wood pulp, lower floor is wood pulp.This absorptive core has good diffusion and lower bleeding back, but in use procedure, still effectively cannot improve deformation of core.
Composite absorbent core after a kind of improvement, deformation of core can be improved, this composite absorption core body is generally made up of the loft non-woven cloth of upper sealing coat, medial support structures, macromolecule water uptake resin, upper and lower hot melt adhesive layer, lower sealing coat, also part manufacturer is had to run business into particular one inching to absorptive core, change the kind of upper and lower layer insolated layer materials, or wet-strength paper or hydrophilic spinning building replace dust-free paper, or hydroscopic high-molecular resin proportioning etc. in adjustment absorptive core.Usually also have manufacturer on absorptive core, suppress grid or striped, make absorptive core surface more closely thinner, make surperficial water conservancy diversion better effects if, but, in the process of the above absorptive core product of actual use, often there is several drawback:
The SAP distribution of absorptive core can not form effective distribution gradient, to improve the distribution of body fluid when absorbability goods absorb.
The SAP of absorptive core is glued on upper and lower two-layer sealing coat mostly, and upper and lower layering is obvious.After urine met by core body thus, upper strata macromolecule water uptake undergoes rapid expansion, causes gel blockage, has a strong impact on double absorption speed, causes the dry-ness decline in top layer.
The upper and lower layer of absorptive core is bonded by PUR and middle loft non-woven cloth, if resin added is few, PUR adheres to hydroscopic high-molecular resin, and upper strata compacted flakes and lower floor's compacted flakes cannot be bonded with loft non-woven cloth, cause absorptive core to fall apart layer, cannot produce.If resin added is many, the glue-line that one deck blocks water can be formed between dust-free paper and loft non-woven cloth, affect infiltration rate.
Due to the existence of above-mentioned drawback, its macromolecule addition is subject to certain restrictions, and for improving the absorption characteristic of absorbing products, can only adopt wider, longer composite absorbent core.Width is widened, and after making product, crotch is wider, and wearing comfort reduces, extended length, and macromolecule utilization rate overall after making product significantly reduces.

Further, described fractionated polymer fabric swatch, fractionated polymer fabric swatch is flexibly connected with fixed axis.
Further, described fractionated polymer fabric swatch is porose, and aperture can be heterogeneous.
Further, described macromolecule distribution adjusting device is one group of macromolecule profile adjustment hopper, and this group macromolecule profile adjustment hopper is positioned in below metering axle, on the support above base material breadth.
Further, described macromolecule profile adjustment hopper entrance section area, is greater than exit area.
Further, described macromolecule profile adjustment hopper, exit area can regulate.
Further, the support height of macromolecule profile adjustment hopper is settled to regulate.
The quantity of further fractionated polymer fabric swatch, can select according to cutting fabric width;
Further, the width of fractionated polymer fabric swatch, according to the height that distribution grid is placed, selects; The width of the hopper lower surface that preferred fabric swatch is formed and breadth is as far as possible close, preferably 5 ~ 10mm;
Further, this macromolecule distribution adjusting device is one group of macromolecule profile adjustment hopper; This group hopper quilt
Be placed in below metering roll, on hopper support above base material breadth;
Further macromolecule profile adjustment hopper is cone, and entrance section area is greater than exit area;
The further macromolecule profile adjustment hopper side's of being cone or cone;
Further macromolecule profile adjustment hopper exit area of section size is adjustable;
The support height of further arrangement macromolecule profile adjustment hopper is adjustable;
The beneficial effects of the utility model are:
Because macromolecule can form effective distribution gradient, thus significantly improve the absorption characteristic of composite absorbent paper, improve the performance of absorbing products; Simultaneously owing to having effective macromolecule distribution gradient, the course of processing of absorbent paper can be improved significantly, reduce material loss, cutting blade abrasion.
