Description
Technical field
The present invention relates to hygienic material field, in particular to a kind of super soft liquid absorbent wick and its preparation system and technique.
Background technique
Paper diaper for baby and adult incontinence pant are known for everyone, and paper diaper especially for baby are convenient to use wide because of it
Trusted by everybody, especially baby's sleeping at night when can all use paper diaper to wet the bed to prevent night to influence baby and parent
Sleep quality.
The predominantly liquid absorbent wick that absorption is played in paper diaper, such as the Chinese invention of Patent No. 201010044865.X
Shown in patent, it discloses a kind of polymer compound core bodies and preparation method thereof, as shown in figure 4, existing core is mostly by upper
Layer clean paper layer 1, lower layer's clean paper layer 2, intermediate loft non-woven layer of cloth 3 and the high score being distributed in loft non-woven layer of cloth 3
Sub- water-absorbing resin rouge particle composition, raw material needed for core are more and upper layer and lower layer clean paper layer and intermediate loft non-woven cloth
Pass through the connection of the adhesive such as hot melt adhesive between layer.As shown in figure 5, the preparation system of existing core generally comprises bottom dust-free paper
It unreels cylinder 6, bottom dust-free paper glue spraying head 8, intermediate loft non-woven and lays reel 5, loft non-woven cloth bottom surface hydroscopic high-molecular resin
It is dustless that flusher 10, loft non-woven cloth surface hydroscopic high-molecular resin flusher 11, surface layer dust-free paper unreel cylinder 4, surface layer
Paper glue spraying head 9 and finished product reel 7, surface layer dust-free paper unreel cylinder 4 and upper layer clean paper layer 1 are delivered to surface layer dust-free paper glue spraying head
9 carry out glue spraying, are then sent to the top of intermediate loft non-woven layer of cloth 3, and bottom dust-free paper unreels cylinder 6 for lower layer's clean paper layer
2, which are delivered to bottom dust-free paper glue spraying head 8, carries out glue spraying, is then sent to the lower section of intermediate loft non-woven layer of cloth 3, upper layer is dustless
Paper layer 1, lower layer's clean paper layer 2, intermediate loft non-woven layer of cloth 3 press to form core by pressure roller, wind finally by finished product
Cylinder 7 is wound.
Although the production of core may be implemented in above-mentioned preparation system, but have the disadvantage in that 1, Preparation equipment is more, technique
It is complicated；2, it prepares that auxiliary material required for core is more, causes the waste of resource, it is at high cost；3, it is realized and is bonded by glue spraying, not ring
It protects；4, hydroscopic high-molecular resin Vertical Free is sprayed on loft non-woven cloth surface, it is difficult to the inside of loft non-woven cloth is actually entered,
It is unevenly distributed；5, it is difficult to even cannot achieve the online production of paper diaper etc. using the Preparation equipment of above-mentioned core.
