Description
Technical field
The present invention relates to hygiene article sector more particularly to a kind of paper diaper and its preparation side with concave-convex type bottom
Method.
Background technique
Traditional paper diaper, structure generally comprise from top to bottom the liquid permeability surface layer of successively lamination setting, absorber and
The left and right magic after paper diaper at waistline is arranged in opaque liquid bottom, and the frontal waist plaster before paper diaper at waistline is arranged in
Button, is arranged in the calf circumference elastic of paper diaper both lateral sides, opaque liquid bottom usually by breathable films and setting breathe freely it is thin
Non-woven fabric compounded below film forms, this layer of non-woven fabrics is usually smooth shape, is bonded tightly with the thigh of user when in use
Close, permeability is bad, especially when its user is baby, since the skin of baby is more delicate, during the broiling summer
In use, the femoribus internus contact area of opaque liquid bottom and baby are very big, cause the gas permeability at thigh position poor, uses
It is more uncomfortable.
China Patent No. 201220250982.6 discloses a kind of dry and comfortable paper diaper, including the gear from top to bottom set gradually
Water layer, pro-skin surface layer, guide layer, absorptive core and film layer further include one saturating below film layer
Gas bottom, the pro-skin surface layer and ventilative bottom are in concave convex texture structure, and the patent claims are recessed using the solid on pro-skin surface layer
Infiltration under burr road spreads urine quickly along groove, is quick, and it is small by the burr of pro-skin surface layer and ventilative bottom reduction baby
The direct contact area of hip, femoribus internus and paper diaper, so that paper diaper are more ventilative, dryer and comfortableer comfortable, still, baby makes
When with paper diaper, only in ventilative bottom setting concave convex texture, there is no methods to reach the effect, and the leg of baby, which is in, stretches
The concave convex texture can be flattened when state or clamped condition, the contact area of paper diaper and thigh is still very big.
Summary of the invention
Therefore, for the above content, the present invention provides a kind of preparation method of paper diaper with concave-convex type bottom, solves
The paper diaper bottom and user's contact area of the prior art lead to greatly air-locked problem.
In order to achieve the above objectives, the present invention is achieved by the following technical solutions: a kind of paper with concave-convex type bottom
The preparation method of urine pants, including following processing step:
(1) preparation of liquid permeability surface layer；
(2) preparation of absorber；
(3) preparation of opaque liquid bottom: the opaque liquid bottom includes breathable films and is arranged under breathable films
The non-woven fabrics of side；
The opaque liquid bottom the preparation method comprises the following steps: a, pretreatment non-woven fabrics: side of the non-woven fabrics to be continuously conveyed
Formula is sent into a pair of of pressure roller assembly, and the non-woven fabrics for the groove that surface has in array distribution is obtained after the processing of pressure roller assembly；
Spacing between each groove is 0.5-1.5cm, and the depth of each groove is 1-3cm, and the width of each groove is
0.5-2cm；
B, filling flexible supporter in the groove of non-woven fabrics after the pre-treatment: the flexible support is to be continuously conveyed
Mode is sent into each groove；
C, glue spraying: in nonwoven surface and the flexible support surface glue spraying being packed into groove；
D, composite ventilating film: in the compound one layer of breathable films of nonwoven surface for being filled with flexible support.
A further improvement is that: the groove distributed areas at least account for the area of non-woven fabrics 2/3.
A further improvement is that: defining paper diaper has the longitudinal direction alongst extended and transverse direction normal thereto,
Each groove distribution mode are as follows: on the basis of the longitudinal midline of paper diaper, to the direction of both lateral sides since longitudinal midline,
The distance between each described groove gradually becomes smaller.
A further improvement is that: on the basis of the longitudinal midline of paper diaper, to the side of both lateral sides since longitudinal midline
To the depth of each groove gradually deepens.
A further improvement is that: on the basis of the longitudinal midline of paper diaper, to the side of both lateral sides since longitudinal midline
To the width of each groove gradually broadens.
A further improvement is that: the flexibility flexible support is water repellent nonwovens ring layer material or strip bulky nonwoven cloth
Or PU foam.
By using preceding solution, the beneficial effects of the present invention are: of the invention a kind of with concave-convex type bottom
The preparation method of paper diaper, the preparation including opaque liquid bottom, opaque liquid bottom include breathable films and are arranged under it
The non-woven fabrics of side during the preparation process first pre-processes non-woven fabrics, its surface is made to form the groove in array distribution,
Then the filling flexible supporter in groove, then the compound upper breathable films of glue spraying, the liquid-tight obtained by these step process
Property its bottom surface of bottom have in array distribution protrusion, in baby in use, the opaque liquid bottom and the thigh of baby connect
Contacting surface product is small, and the opaque liquid bottom will not be pressed into smooth shape due to the presence of flexible support when in use, really real
The now function small with baby's thigh contact area, so that huckle is more ventilative comfortable when in use by baby.Further, described
Groove distributed areas at least account for the area of non-woven fabrics 2/3, so that the convex portion of non-woven fabrics is accounted for its most position accordingly, greatly
Leg air permeability effect is more preferably.Preferably, on the basis of the longitudinal midline of paper diaper, to the side of both lateral sides since longitudinal midline
To the distance between each described groove gradually becomes smaller, and the depth of each groove gradually deepens, and the width of each groove is gradually
It broadens, so that the more more Gao Gengkuan of place protrusion closer to thigh position, less with the contact area of thigh, air permeability effect is more
It is good.
