Abstract
The invention discloses a novel composite core material for paper diapers and a preparation method of the novel composite core material. The novel composite core material is prepared from a fluffy non-woven fabric, a polymer absorbent material and dust-free paper, wherein wood pulp fiber is embedded into the bottom layer of the fluffy non-woven fabric. The novel composite core material has the advantages that the phenomenon that agglomerating and lumping are generated in the using process is effectively avoided; meanwhile, the fault phenomenon generated after longitudinal and transverse stretching is reduced, and the skin friendliness and the comfort degree are improved; after urine seeps downwards to arrive at the embedded wood pulp fiber, the urine diffuses around, therefore, the absorption speed of the urine is increased, the liquid absorption time of the polymer absorbent material is prolonged, and the reverse seepage amount of the urine is decreased.
Description
Technical field
The present invention relates to the core material of amenities, specifically a kind of paper diaper NEW TYPE OF COMPOSITE core material.
Background technology
In existing technology, the core body of paper diaper typically adopts whole wood pulp material to constitute, the core being constituted due to whole wood pulp
Body easily produces conglomeration in use and acts the phenomenon sticking together, and also will can produce the problem of tomography after core body vertically and horizontally stretching,
Reduce comfort level when paper diaper are worn, the use of impact paper diaper, the urine absorption speed of core body and reverse osmosis amount are also simultaneously
The difficult problem that must capture is improved it is therefore desirable to make to the core body of paper diaper.
Content of the invention
In order to overcome the deficiencies in the prior art, the present invention provides a kind of paper diaper NEW TYPE OF COMPOSITE core material and its manufacturer
Method.
The technical solution adopted for the present invention to solve the technical problems is：A kind of paper diaper NEW TYPE OF COMPOSITE core material, bag
Include loft non-woven cloth, macromolecule water absorbent material, dust-free paper, the bottom of described loft non-woven cloth is embedded with wood pulp cellulose.
Wherein：The upper and lower surface of described loft non-woven cloth is respectively equipped with the macromolecule water absorbent material of uniform arrangement and dustless
Paper.
Wherein：Bonded by hot melt adhesive layer between described macromolecule water absorbent material and dust-free paper.
Wherein：The thickness of described loft non-woven cloth is 2-5 millimeter.
Wherein：The density of described macromolecule water absorbent material is 50-150 gram every square metre.
Wherein：The thickness of described dust-free paper is 0.2-0.5 millimeter.
Wherein：The length of described wood pulp cellulose is 0.8-1.2 millimeter, and the density of described wood pulp cellulose is 5-15 gram every square
Rice.
Wherein：The thickness of described hot melt adhesive layer is 0.08-0.15 millimeter.
A kind of manufacture method of paper diaper NEW TYPE OF COMPOSITE core material, including step once：
A, using pulverizer, wood pulp cellulose is smashed, the length making wood pulp cellulose is between 0.8-1.2 millimeter；
B, loft non-woven cloth is placed in the space of sealing, the wood pulp cellulose after smashing is utilized air compressor with negative pressure 20,000
The pressure of handkerchief is sprayed on loft non-woven cloth；
C, macromolecule water absorbent material is sprinkled upon on loft non-woven cloth with density for 50-150 gram every square metre；
D, PUR is sprayed on macromolecule water absorbent material with thickness for 0.08-0.15 millimeter simultaneously；
E, dust-free paper is bonded on macromolecule water absorbent material；
F, by loft non-woven cloth invert, repeat c, d, step e；
G, finished product is carried out heating, pressurized treatments, rolling after cooling, cutting obtains composite core material.
The invention has the beneficial effects as follows：This composite core material is prevented effectively from and produces conglomeration in use and act showing of sticking together
As solving the fault-layer-phenomenon after vertically and horizontally stretching, improving skin-friendly and comfort level, reach embedded wood pulp when oozing under urine simultaneously
After fiber, urine spreads toward surrounding, accelerates the infiltration rate of urine, extends the imbibition time of macromolecule water absorbent material simultaneously, subtracts
The reverse osmosis amount of oliguresis liquid.
Brief description
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the present invention.
Specific embodiment
With reference to Fig. 1, a kind of paper diaper NEW TYPE OF COMPOSITE core material, including loft non-woven cloth 1, macromolecule water absorbent material 2, no
Dirt paper 3, the bottom of described loft non-woven cloth 1 is embedded with wood pulp cellulose 4.Wherein, the upper and lower surface difference of described loft non-woven cloth 1
It is provided with macromolecule water absorbent material 2 and the dust-free paper 3 of uniform arrangement.Wherein, between described macromolecule water absorbent material 2 and dust-free paper 3
Bonded by hot melt adhesive layer 5.
Further：The thickness of described loft non-woven cloth 1 is 2-5 millimeter.Wherein, described macromolecule water absorbent material 2 is close
Spend for 50-150 gram every square metre.Wherein, the thickness of described dust-free paper 3 is 0.2-0.5 millimeter.Wherein, described wood pulp cellulose 4
Length is 0.8-1.2 millimeter, and the density of described wood pulp cellulose 4 is 5-15 gram every square metre.Wherein, the thickness of described hot melt adhesive layer 5
Spend for 0.08-0.15 millimeter.
A kind of manufacture method of paper diaper NEW TYPE OF COMPOSITE core material, including step once：
A, using pulverizer, wood pulp cellulose 4 is smashed, the length making wood pulp cellulose is between 0.8-1.2 millimeter；
B, loft non-woven cloth 1 is placed in the space of sealing, the wood pulp cellulose 4 after smashing utilizes air compressor with negative pressure 20
KPa pressure be sprayed on loft non-woven cloth 1；
C, macromolecule water absorbent material 2 is sprinkled upon on loft non-woven cloth 1 with density for 50-150 gram every square metre；
D, PUR is sprayed on macromolecule water absorbent material 2 with thickness for 0.08-0.15 millimeter simultaneously；
E, dust-free paper 3 is bonded on macromolecule water absorbent material 2；
F, loft non-woven cloth 1 is inverted, repeat c, d, step e；
G, finished product is carried out heating, pressurized treatments, rolling after cooling, cutting obtains composite core material.
In the present invention：Described hot melt adhesive layer 5 adopts hydrophilic PUR, that it changes the hydrophobicity of general PUR,
Make PUR applying mode and spraying glue consumption no longer affect urine compound core body quick under blend the logical of many sub-percolations
Fluidity.
