The absorber structure has the advantages that the design is reasonable; the structure is simple; the process is simple; the manufacturing is easy; and the practicability is high. The absorber structure has high liquid diffusibility and high liquid downward seepage speed, and also has good drying performance.
Description
Technical field
The present invention relates to disposable sanitary articles technical field, be specifically related to a kind of absorbent structure for disposable sanitary articles.
Background technology
Disposable sanitary articles such as baby paper diaper, the function of absorber is to absorb and keep effluent, such as urine, make to return milliosmolarity to minimize to keep being dried simultaneously, the absorbed layer of the absorbent article that major part is current commercial comprises as temporary transient liquid storage and the wood pulp of the pulverizing of absorbing material, have and absorb and the absorption resin particle of water holding capacity, and wrap up with non-weaving cloth or toilet paper.When absorbed layer faces big quantity of fluid, when especially absorber a part faces hold-up state, absorbable polymer, it sometimes appear that gel blocking phenomenon, causes liquid to be difficult to other positions and spreads, and after causing disposable sanitary articles imbibition, drying property is poor.
Summary of the invention
The purpose of the present invention is aiming at the defect that prior art exists, it is provided that a kind of absorbent structure for disposable sanitary articles.
Its technical scheme is: for the absorbent structure of disposable sanitary articles, including top layer, bottom and absorbed layer, described absorbed layer at least includes puffy fiber and absorbent polymer particles, and puffy fiber and absorbent polymer particles are wrapped up to be formed the integument of absorbed layer on chip, on described absorbed layer, plane dissipates to surrounding from central region and is provided with at least six passage, described passage is the close of described integument outer wall, there is the longitudinal wall at less puffy fiber and absorbent polymer particles and the cavity surrounded containing the integument outer wall at less puffy fiber and absorbent polymer particles；Described top layer, absorbed layer and bottom sequentially pass through the fixing connection of adhesives from top to bottom.
Described passage is that sector extends by six direction outside in the middle part of absorbed layer, and one end that wherein passage is close is arranged on the geometry central region of absorbed layer, and the width of each passage is at least the 3% of described absorbed layer lateral dimension.
5% the 40% of a length of absorbed layer longitudinal size of described passage.
Described absorbable polymer is crosslinked salt polyacrylate base polymer, and described crosslinking absorbable polymer absorbs the ability of normal saline under the pressure of 0.7 pound per square inch and is not less than absorption 7 grams per hour per gram；Or the swirl method infiltration rate of absorbable polymer is faster than 100 seconds；Or its centrifuge retention capacity is not less than 22g/g；Or its gelatin polymer leads to fluidity and is not less than 20 × 10-9s。
Described top layer includes at least one layer of non-woven structures.
Described bottom includes at least one of which PE film and one layer of non-weaving cloth, and is bonded by binding agent.
Described integument is toilet paper, wet-strength paper, non-weaving cloth or the composite bed for preparation of being fitted by toilet paper, wet-strength paper and non-weaving cloth.
The present invention compared with prior art, has the advantage that reasonable in design, simple in construction, technique simply, easily make, practical.It has liquid high diffusibility and liquid relative superiority or inferiority infiltration rate degree, has good drying property simultaneously.
