Description
Technical field
The utility model relates to paper diaper technical field more particularly to a kind of ultrathin absorptive cores.
Background technique
Core is mainly based on wood pulp and compound core body at present.Its main advantage and disadvantage is as follows:
Wood pulp core is mixed by Time of Fluff Slurry and water-absorbing resin；Wood pulp core infiltration rate is fast, but easily plays top, tomography.
It is thinning to make core thickness, then need to reduce the dosage of Time of Fluff Slurry, but core easy-to-break layer.If reinforcing core intensity, need
The dosage of lint slurry is increased, but core thickness thickeies at this time, causes gas permeability poor, dresses appropriate decline.
Compound core body is usually 5 layers of structure, by water-absorbing resin, dust-free paper, loft non-woven cloth, the composition such as non-woven fabrics.Water suction
Resin is respectively placed in loft non-woven cloth upper and lower surface, and not discontinue after core absorbs does not rise and sticks together；Compound core body almost applies in entire surface
Hot melt adhesive is covered, and water-absorbing resin is made also to be uniformly distributed the product to be formed in the almost entire surface of lamella.It is such slim
Core, when urine is once largely discharged, water-absorbing resin has little time imbibition, and there are leakage of urine risks.Hot melt adhesive usage amount is excessive,
The comparable part of water-absorbent resin surfaces is capped, cannot give full play to water imbibition, simultaneously because be clamped between lamella and by
The constraint of hot melt adhesive, water-absorbing resin expansion etc. cause compound core body infiltration rate slow, leakage of urine etc..
Either become very thick after wood pulp or the water suction of compound core body water lock sandwich layer, comfort is poor；The blocked up paper urine of child wear
The walking of trousers length time, will form ' toed-out ' foot, it is also possible to cause permanent injury to skeleton development over time.According to 2011
August Tianjin channel on the 16th, one entitled " to seek help！Baby two years old, find O shape leg！Suspection is that the misfortune that paper diaper are invited leads to leakage of urine
Phenomenon ", the paper diaper of Tianjin channel reporter four brands higher to sales volume on the market are tested, the water suction of these paper diaper
It can all expand afterwards, broaden and thicken.The water absorbing properties the strong more expands, and the demi-inflation being clipped among two leg of child is most obvious, very
To can reach absorb water before four or five times of thickness.The authoritative expert Tianjin women and children health center chief physician Li Yi people say: " child
Son wears paper diaper and walks for a long time, will form ' toed-out ' over time, as can or can not cause permanent injury to skeleton development
It need to be investigated." in the parent-offspring forum of Tianjin, numerous mothers represent worry to this.Become after so that paper diaper is absorbed water
It is thinner to have become industry key issues urgently to be solved.
For this purpose, the utility model proposes a kind of ultrathin absorptive cores.
