Description
Technical Field
The invention relates to the technical field of paper diapers, in particular to an absorption core body of a paper diaper.
Background
The paper diaper product quickly replaces the traditional diaper by virtue of the advantages of convenience, sanitation, comfort and the like. According to the report of the nineteenth international scientific and technological exhibition of living paper and international seminar at the meeting, the total consumption of the infant diaper in our country in 2011 is 184.6 billion yuan, which is 27.7% higher than that in the last year and accounts for 39.8% of the total domestic sales of the absorbent sanitary products in the same year. With the improvement of the living standard of people, people increasingly accept the care function of the paper diaper on babies.
The paper diaper is a liquid absorption and control system built by multiple layers of non-woven materials and mainly formed by compounding a surface layer, a flow guide layer, an absorption core layer, a bottom film, leg opening edge leakage prevention edges, magic tapes, spandex filaments and a hot melt adhesive which bonds all parts together. The paper diaper product is not selected properly or used improperly, and the problems of allergy and eruption of the infant are easy to occur. For the paper diaper, the core is the most important part of the paper diaper, and the traditional paper diaper for the baby adopting the wood pulp fiber core has the defects of poor water absorption and locking property, poor air permeability and the like, so that the requirements of the current consumers cannot be met. Therefore, improvements to the absorbent core of diapers have been one of the directions in which the diaper field is being developed.
The absorption effect of the existing paper diaper absorption core is also poor, which is mainly characterized in that the core is poor in transverse and longitudinal diffusion and infiltration capacity; the core body usage rate is less than half, and after urine is absorbed, the absorption core body is easy to break, lump and agglomerate. Poor absorption and diffusion effects can easily cause side leakage, back leakage, reverse osmosis, and other undesirable conditions. The problems of 'red buttocks', 'diaper rash', 'eczema' and the like of the baby are caused, and the main reason is that the design of the absorption core body of the diaper is not ideal.
