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.
