Description
Technical field
The present invention relates to absorbing material technical field, more particularly to a kind of health composite absorbent material and preparation method.
Background technology
The amenities such as sanltary towel in the market, panty liner, infant, old paper diaper, diaper are all
It is traditional three-decker, i.e. surface layer, sandwich layer, bottom are bonding with PUR between layers of material.Its center core layer decides whole
The performance of individual product, and traditional core structure is mainly cotton, adhesive-bonded fabric, Time of Fluff Slurry or more material compound addition polyphosphazene polymer
Compound is used for absorbing the liquid of outflow.Concrete structure is：Water-absorption fiber base material (toilet paper or dust-free paper) surface layer+dustless cotton or suede
Hair slurry (the inside addition water-absorbent besin particles SAP having)+water-absorption fiber base material (toilet paper or dust-free paper) bottom.The system of sandwich layer
Make method all using composite dry process, mainly want following two production technologies：
I type：Raw material (non-woven fabrics or dustless paper base material bottom) --- bottom glue spraying -- spreads cotton (Time of Fluff Slurry, dustless water suction
Cotton) -- sprinkling water absorbing resin particle SAP-- non-woven fabrics or dust-free paper base material surface layer glue spraying-composite molding -- cut.
II type：Raw material (non-woven fabrics or dustless paper base material bottom) --- bottom glue spraying -- uniformly sprays water absorbing resin particle
SAP-- non-woven fabrics or dust-free paper base material surface layer glue spraying -- composite molding -- are cut.
Above two method is dry manufacturing process, the problem of presence using the finished product obtained by above-mentioned dry process：
1. finished product (containing dustless cotton or Time of Fluff Slurry) thickness of I type processing is big (200g/ ㎡ or so), comfortableness is poor；
2. I mandrel layers can not bond easy agglomerate, became uneven is caused, water suction is irregular, and comfortableness is poor, water lock poor performance.
3. inside the type of I type II resin particle of addition can not good bond, cause particle wadding conflux to move, water suction is uneven, lock
Water poor performance.
The processing of glue spraying that 4 two sides are made, causes that whole sandwich layer absorption speed is slow, permeable, water absorption rate declines, and not environmentally.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of comfortableness is good, close structure, frivolous, absorption speed is fast, inhales
