Description
Technical field
The present invention relates to hygiene article sector, more particularly to one kind can be used for paper diaper, nappy, sanitary napkin, protection pad,
Collapsible absorptive core on the various disposable sanitary articles such as underpants back boxing.
Background technology
The absorptive core of disposable sanitary articles is roughly divided into two kinds in the market：One kind is conventional suction core body, i.e.,
Time of Fluff Slurry and the core body of high exhaustion mixing, such a core body are that online molding process is short, and plasticity is strong, and absorbability is good, into
This is low, but easily rises and stick together after absorbing water, easy-to-break layer；Another kind is composite absorption core body, i.e. non-woven material and high exhaustion is compound
Core body, such a core body is offline composite molding, thickness of thin, do not risen after water suction stick together, not easy-to-break layer, but absorbability is poor, offline
Production technology is grown, and cost is higher.
The content of the invention
It is an object of the invention to for above-mentioned problem and shortage, there is provided a kind of online molding process is short, absorbs
Property it is good, cost is low, and does not rise and stick together after absorbing water, the collapsible absorptive core of not easy-to-break layer.
The technical proposal of the invention is realized in this way：
A kind of collapsible absorptive core, including at least one layer of fiber assembly and at least one layer of high exhaustion, the fiber
Aggregate and high exhaustion are bonded PUR, are thermally bonded, ultrasonic bonds or compression it is fixed by way of it is compound after, then
Absorptive core is formed according to a folding mode.
Further, wherein the fiber assembly is in toilet paper layer, clean paper layer, nonwoven layer, fiber web layer
At least one or its any combination.
Further, wherein square metre quality of the toilet paper layer is 5 ~ 100 grams/m；The clean paper layer
Square metre quality is 10 ~ 200 grams/m；Square metre quality of the nonwoven layer is 5 ~ 100 grams/m；The fiber
Square metre quality of stratum reticulare is 5 ~ 150 grams/m.
Further, wherein square metre quality of the toilet paper layer is 10 ~ 35 grams/m；The clean paper layer
Square metre quality is 20 ~ 80 grams/m；Square metre quality of the nonwoven layer is 10 ~ 50 grams/m；The fiber
Square metre quality of stratum reticulare is 20 ~ 100 grams/m.
Further, wherein square metre quality of the high exhaustion is 0.1 ~ 250 gram/m.
Further, wherein square metre quality of the high exhaustion is 5 ~ 150 grams/m.
Further, wherein square metre quality of the PUR is 0 ~ 50 gram/m；The heat bonding or ultrasonic wave
The temperature of bonding is 80 ~ 250 DEG C.
Further, wherein square metre quality of the PUR is 1 ~ 10 gram/m；The heat bonding or ultrasonic wave
The temperature of bonding is 100 ~ 180 DEG C.
Further, wherein the folding mode refers to fold along machine direction.
Further, wherein the folding mode includes V-type folding, C-fold, G types fold, Ω types fold, Z-type folding
Folded, Σ types fold or more Z-folds.
The present invention is as a result of a folding mode by least one layer of fiber assembly and at least one layer of high exhaustion
The structure of composite absorption core body is made, can not only keep that conventional suction core body online molding process is short, and absorbability is good, and cost is low
The advantages of, and the thickness of thin of composite absorption core body, do not risen after water suction stick together, not discontinue the advantages of, and efficiently solve tradition
The shortcomings that sticking together tomography is easily acted after the water suction of absorptive core, and the long cost of technique of composite absorption core body is high, the shortcomings that absorbability difference.
In addition, the collapsible absorptive core that the present invention makes, prevents the high exhaustion of absorptive core from leaking outside without integument, from
And it reduce further cost.The collapsible absorptive core that the present invention makes, can be according to different folding modes in absorptive core
Inside sets at least one layer of guide layer, so as to improve the absorbent properties of core body and utilization rate.The collapsible absorption that the present invention makes
Core body, at least one layer of application of anti-leakage layers can be set inside absorptive core according to different folding modes, be absorbed so as to which Anti-leakage type be made
Core body.
