Description
Technical field
The present invention relates to hygiene article sector more particularly to a kind of preparation methods of the paper diaper with concave-convex type surface layer.
Background technique
There are mainly two types of materials for paper diaper surface layer currently on the market, and one is synthetic fibers, such as hot melt adhesive nonwoven
Cloth and spun-bonded non-woven fabrics, another kind are pure cotton non-woven fabrics, pure cotton non-woven fabrics used in existing paper diaper surface layer, are by de-
The pure cotton non-woven fabrics of rouge working process, pure cotton, that is, absorbent cotton by degreasing working process are to carry out degreasing to raw cotton and dewax
Good, the soft cotton fiber of the water absorbing capacity arrived, raw cotton carry fibrous face layer after ungrease treatment when in addition to taking off cotton picking
Rouge and wax outside, the stain and impurity of fibrous face layer are also washed away together, thus absorbent cotton is a kind of clean very much and clean
Fiber, it is pure white and soft using pure cotton non-woven fabrics made of absorbent cotton.Pure cotton non-woven fabrics by degreasing working process are hydrophilic
Property is very good, and water absorbent rate can reach 20 times of own wt or more, use this pure cotton non-woven fabrics for the paper diaper of surface layer
Although infiltration rate is fast, water conservation water lock is good, complete with the skin of baby since this pure cotton non-woven fabrics structure is more smooth
It releases, and since it is retained, water lock performance is good, and damp is strong after absorption of liquid, and baby is particularly easy to occur after red again
Rash.
China Patent No. 2015204381163 discloses a kind of surface layer, and the side that the surface layer is contacted with skin is provided with
Protrusion embossing, the outer surface of the protrusion embossing be it is smooth arc-shaped, in use, by the top surface of protrusion embossing with
The skin of baby contacts, and still, since protrusion is embossed no backing layer support, contacts that press will be by with baby skin after use
Pressing forms face contact, thus there is no the contacts area that method reduces surface layer and skin, are not achieved and improve comfort
Effect.
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 surface layer, solves
Damp is easy to cause by force in turn after the paper diaper imbibition of the prior art there is the problem of erythema.
In order to achieve the above objectives, the present invention is achieved by the following technical solutions:
A kind of preparation method of the paper diaper with concave-convex type surface layer, including liquid permeability surface layer, absorber, opaque liquid bottom
The preparation of layer and the preparation step that the liquid permeability surface layer, absorber and opaque liquid bottom are combined into one, it is described
The preparation of fluidity surface layer the following steps are included:
(2) hydrophilic nonwoven fabrics are prepared, and are embossed punching processing to it；
(2) water-absorbing material is sprayed on the hydrophilic nonwoven fabrics by being embossed punching processing, makes water-absorbing material in array
The aggregation block of formula is distributed on hydrophilic nonwoven fabrics, and the distance between each described aggregation block is 2-5mm, the height of each aggregation block
For 4-5mm, the hydrophilic nonwoven fabrics that aggregation block is distributed with are obtained；
(3) one layer of glue uniformly glue spraying: is sprayed on the hydrophilic nonwoven fabrics for be distributed with aggregation block；
(4) compound layer of non-woven fabric, institute's non-woven fabrics are compounded in by the hydrophilic of step (3) processing in a manner of being continuously conveyed
On non-woven fabrics；
(5) it is pressed by pressure roller, the week edge of aggregation block is made to be adhesively fixed with non-woven fabrics；
(6) water repellent finishing agent is sprayed on the non-woven fabrics in aggregation block, the water repellent finishing agent covers in aggregation block
The area of nonwoven surface 1/4-1/3；
(7) it dries.
A further improvement is that: the concrete operations mode of step (2) are as follows: be arranged above hydrophilic nonwoven fabrics a plurality of along vertical
To water-absorbing material adding set arranged side by side, water-absorbing material is sprayed onto hydrophilic by the water-absorbing material adding set
On non-woven fabrics, the transmission speed of hydrophilic nonwoven fabrics is controlled at 12-18 ms/min.
A further improvement is that: in step (6), the mode of nonwoven surface is added in water repellent finishing agent specifically: in step
(5) a plurality of water repellent finishing agent adding sets being arranged side by side along longitudinal direction of setting above the product that processing obtains, step (5) processing
Obtained product is with the successional transmission of 12-18 ms/min of speed.
A further improvement is that: the water repellent finishing agent is no fluoro water proofing agent.
By using preceding solution, the beneficial effects of the present invention are: of the invention a kind of with concave-convex type surface layer
Paper diaper, liquid permeability surface layer include hydrophilic nonwoven fabrics, and embossed holes, the hydrophilic nonwoven fabrics are evenly equipped on the hydrophilic nonwoven fabrics
Be equipped with the lug boss in array distribution, baby when in use, due to the setting of the array lug boss, surface layer and baby's skin
The contact area of skin is less, significantly less compared to the paper diaper contact area of traditional flush-type, and fills in the lug boss
There is water-absorbing material, so that the lug boss has biggish support force, is less likely to occur to collapse when contacting use with infant skin
And then become smooth shape, furthermore, the top spray of the lug boss is equipped with water repellent particle, which sprayed by no fluoro water proofing agent
It is located at the top of lug boss and is made by drying, water repellent particle covers the area of lug boss top 1/4-1/3, makes and infant skin
The region of contact be able to maintain preferably it is dry-ness, promoted comforts of use, reduce erythema.
Preferably, the surface of lug boss is circular arc type, in baby in use, the skin contact part plane of paper diaper and baby
Product is less and more comfortable when using, and does not have spine sense；,
It is whole that water repellent is sprayed in the preparation method of the paper diaper with concave-convex type surface layer, on the non-woven fabrics in aggregation block
When managing agent, the conveying speed of the non-woven fabrics containing aggregation block and the conveying speed of hydrophilic nonwoven fabrics are suitable, so that water repellent finishing agent
It can effectively be distributed on the corresponding non-woven fabrics in aggregation block top.
