Description
Technical field
The present invention relates to a kind of absorptive cores of paper diaper, and in particular to a kind of absorbent cores for disposable sanitary articles
Body structure.
Background technique
Disposable sanitary articles such as baby paper diaper has obtained extensive utilization at present, constantly mentions as people's lives are horizontal
It rising, people are more deep for the understanding of baby paper diaper, and the requirement for baby paper diaper is also higher and higher, ultra-thin, comfortable,
The dry and comfortable quality valued the most that baby paper diaper is selected as people, and baby's paper urine of domestic exclusive compound core body structure
Share is increasing in the market for trousers, how to accomplish that thinner, more comfortable, dryer and comfortableer is an important topic instantly.Also have
It is thinner, more comfortable, dryer and comfortableer that many patents refer to how to accomplish, but all there are also shortcomings, such as publication number CN
The patent of 202490091U, core design at ultra-thin absorbent core and it is intermediate thicken core, take into account uptake and ultra-thin, but
It is to be still thicker core among it, and low cost materials can all increase；Such as the patent of publication number CN 204016631U, adopt
With five-layer structure core, upper layer and undermost dust-free paper are only changed into wet-strength paper, improve cost, than traditional five
Layer core wants thin, but still has deficiency；, really can be thinner if patent CN 202821859U uses overall height molecule core,
Material is saved, cost is lower, but what its sense of touch for not accounting for high molecular mobility and core can be opposite becomes very poor,
Macromolecule aggregation is easy to produce gel blocking, makes core infiltration rate, bleeds back and get higher, and deviates from original intention.
Summary of the invention
The present invention in view of the drawbacks of the prior art, provides a kind of absorptive core structure for disposable sanitary articles, should
Absorptive core layer is three layers, only need to carry out a super absorbent resin and broadcast sowing, macromolecule is evenly distributed in loft non-woven cloth,
It improves work efficiency, reduces the use of material, reduce cost.

10-50 grams.
According to the above technical scheme, the Super Absorbent Polymer Particles are polyacrylate quasi polymer, every gram of high water absorption
Property resin physiological saline ability is absorbed under 0.7psi pressure not less than 20g/g, swirl method infiltration rate be no faster than 20 seconds but
It is not slower than 100 seconds or its centrifuge retention capacity is not less than 35g/g.
According to the above technical scheme, the bulky nonwoven fabric, which is used, makes molding non-woven material via hot air technique
Material, the bulky nonwoven fabric grammes per square metre are every square metre 30-60 grams.
According to the above technical scheme, the wrapping layer uses non-woven cloth, which is gathered by polyethylene or polypropylene
Fibres are closed through hot wind, hot rolling, spun lacing, spunbond process production molding.
According to the above technical scheme, the liquid-permeable surface layer uses non-woven cloth, and the non-woven cloth is by polyethylene or poly- third
Alkene polymer fiber is through hot wind, hot rolling, spun lacing, spunbond process production molding.
According to the above technical scheme, the liquid-impermeable bottom has breathable films and non-woven cloth material.
According to the above technical scheme, the breathable films use PE film, and the non-woven cloth material is by polyethylene or polypropylene
Polymer fiber is through hot wind, hot rolling, spun lacing, spunbond process production molding.
According to the above technical scheme, described adhesive uses hot melt adhesive.
Absorptive core structure disclosed by the invention for disposable sanitary articles, the beneficial effect is that, structure is simple,
Production is simple, and paper diaper are thinner, more soft, reduces consumptive material, reduces cost, improves the utilization rate of super absorbent resin.
