Description
Technical field
This utility model relates to a kind of diaper, refers in particular to a kind of diaper that prevents urine reverse osmosis.
Background technology
Diaper is the conventional hygienic article of a kind of baby.In general, diaper is made up of three major parts: surface coating layer, absorbent core layer and base fabric.Surface coating layer also can be called clad.Absorbent core layer also can be called absorptive core, or absorber.Clad is close to baby's health, can impel urine rapid osmotic, makes urine pants top layer keep dry and comfortable.The clad of the diaper on domestic market is non-woven fabrics surface layer substantially, ventilative non-woven fabrics can promote the ventilative degree of urine pants inside, and steam can be circulated to beyond urine pants, discharges in time dampness and steam, effectively reduce the chance that diaper rash occurs, soft comfortable not chafe.Absorbent core layer also can be called absorptive core.The Main Function of absorbent core layer be can capture and absorb fast urine, distribute urine maybe can by capillarity it be diffused in whole sandwich layer, final absorption and storage of urine.The layer structure that on domestic market, the absorbent core layer of diaper is mainly made up of pure wood pulp (Time of Fluff Slurry) and High hydrophilous resin (SAP).Base fabric, is the outermost structure of diaper, has impermeability, can prevent that the moisture in absorbent core layer from oozing out.The base fabric of external a lot of diaper has used the non-woven fabrics of feeling more comfortable, but due on the high side, the diaper base fabric of domestic market is still mainly made up of PE film.Common diaper also has waistline assembly.Waistline assembly is for fixing diaper.
Absorb resin in urine pants with regard to role with regard to the requirement of urine pants and macromolecule, moisture-holding capacity and pressurizing absorption amount are important performances.Next is rate of water absorption and water absorption.Now in urine pants industry, no matter be that rate of water absorption is extremely paid close attention in urine pants manufacturer or urine pants distribution commercial city, think the fast urine pants of the water suction urine pants that have been, the particularly sole criterion of urine pants manufacturer using rate of water absorption as review hydroscopic high-molecular resin quality, but true really not so, the applicant analyzes urine pants chip and can find to be wherein made up of two kinds of raw materials: hydroscopic high-molecular resin and wood pulp.Macromolecule water uptake tree refers to have the feature of high water absorption and high water suction recoverable amount, its water absorption and moisture-holding capacity are tens of wood pulp, and wood pulp is deposited in and has together good capillary tube, produce higher water conservancy diversion peptizaiton, its rate of water absorption is approximately the 5-6 position of hydroscopic high-molecular resin.So both performances have complementarity, the urine pants chip that suitable proportioning and mixing form can reach the effect of optimal absorption speed and water suction recoverable amount.If we pay attention to absorb the speed of urine more, wood pulp is by the best raw material of trousers chip.If but keep the skin of baby's hip dry and comfortable in order to enable while use, the high water yield that hydroscopic high-molecular resin has and moisture-holding capacity could be protected this characteristic of industrialization, this also just hydroscopic high-molecular resin can become the main cause of urine pants chip material of new generation.
In order to understand the relation of hydroscopic high-molecular resin rate of water absorption and water absorption, the applicant uses column water absorption test method to test different hydroscopic high-molecular resins, the applicant finds, just absorption rate faster hydroscopic high-molecular resin after very short time, its absorbtivity just do not increase, Here it is produced high molecular polymer gelling the moon every problem.Hydroscopic high-molecular resin is that a kind of particle surface is through to a certain degree crosslinked high molecular polymer.Its granule in absorbing liquid can rapid expanding while mechanical strength decline; surface is the sticky situation that joins and produce pasty state mutually; glue mutually connection situation if surperficial and seriously will produce cloudy only liquid through having absorbed and expanded granular news gap situation; make infiltration rate be tending towards stagnating, the long-term absorbability of this hydroscopic high-molecular resin and repeatedly absorbability will produce larger problem.The bleeding back for the second time and for the third time of urine pants that is mainly manifested in it can be higher, it can only absorb urinating for the first time of baby, after 2～3h baby again urinate after will because of gelling the moon every problem and make to absorb not smooth, thereby urine pants just cannot ensure baby's the dry and comfortable real synergistic that loses it of skin like this.Therefore, existing diaper ubiquity has the problem of urine reverse osmosis, particularly after repeatedly urinating, above problem is especially obvious, urine, if there is reverse osmosis, can make the skin Long contact time urine of infant, causes the skin allergy of infant, even also can cause red hip, affect growing up healthy and sound of infant.
