Description
Technical field
The invention belongs to personal hygiene article fields, and in particular to a kind of absorbent article processing method of front and back leak-proof.
Background technique
Existing regular absorbent product, structure are substantially: above as a hydrophilic surface layer 4, are for a substratum for waterproofing 8(below
The back side of paper diaper), centre is absorptive core 6；Pressing and forming is cut through one, it is hydrophilic on the outside of the longitudinal both ends of absorptive core 6
Surface layer 4 and substratum for waterproofing 8 bond, and are respectively provided with three-dimensional shield 1 in absorbent article two sides, leak when big to prevent excretion object amount from side
Out, three-dimensional shield 1 be provided with can longitudinal contraction elastic；In addition it is equipped with a pair of of velcro in the rear end sides of absorbent article, with
Just the front and back end of absorbent article is sticky and is worn on human body.
As shown in Figure 1, 2, the longitudinal both ends of the three-dimensional shield 1 of regular absorbent product and the bonding of hydrophilic surface layer 4 form end seal 3,
To prevent excreta from leaking out from preceding back waist region position side, end seal 3 is greater than or equal to 10mm along front and back lumbar region transverse direction width.
But due to the limitation of existing equipment process conditions, the absorbent article that the prior art manufactures, by inhaling at bond site end seal 3
There is the unbonded channel 2 about 0~10mm in the side for receiving core widthwise edge edge, cause when drain object amount it is big when never adhesive channel
Front and back leaks out in 2.
Summary of the invention
The present invention is intended to provide being directed to deficiency of the three-dimensional shield of regular absorbent product in terms of local leakproof, one kind is provided
It can solve the absorbent article processing method of leakage problems at three-dimensional shield end seal.
The technical solution that the present invention solves the problems, such as is: a kind of absorbent article processing method of front and back leak-proof, including walks as follows
It is rapid:
(a) it is glued at the position on three-dimensional shield in conjunction with hydrophilic surface layer；
(b) three-dimensional shield is bonded to form end seal along hydrophilic surface layer longitudinal direction two sides；At this point, at end seal bond site, leaning on
There are unbonded channels for the side on hydrophilic surface layer widthwise edge edge；
(c) before cutting, bonding closure is carried out to unbonded channel；
(d) cutting forms final absorbent article.
In above scheme, a kind of specific embodiment is, after the step (b), further include by band before step (c)
There is the step of hydrophilic surface layer of three-dimensional shield, substratum for waterproofing are bonded with absorptive core respectively；
Then the semi-finished product with unbonded channel are fed again into binding appts, bonding envelope is carried out to unbonded channel
It is stifled, unbonded channel is subjected to the method for bonding closure as heat bonding or ultrasonic bonds.
Another specific embodiment is unbonded channel to be carried out to the method for bonding closure for chemistry in step (c)
Bonding forms bond regions, and infiltrate bond regions to hydrophilic surface layer by being glued below hydrophilic surface layer；And it will have simultaneously
The hydrophilic surface layer of three-dimensional shield, substratum for waterproofing are bonded with absorptive core respectively, are blocked so that unbonded channel be bonded.
Preferably, when carrying out bonding closure to unbonded channel, the transverse width of the bonding sealing region applied is greater than
Or the width equal to unbonded channel.
Preferably, the end seal extends on the outside of hydrophilic surface layer by transverse width of the hydrophilic surface layer widthwise edge along that side,
It bonds base portion and is located on the outside of hydrophilic surface layer edge.
Preferably, the end seal transverse width is greater than or equal to 10mm.
Above-mentioned preferred feature is for guaranteeing sufficiently blocking unbonded channel when local stiffening processing.
The present invention carries out bonding closure to unbonded channel again, so that excreta is no longer from the unbonded logical of three-dimensional shield
It is revealed in road, has the advantages that front and back leak-proof.
