Description
Technical Field
The invention relates to a core material of a sanitary product, in particular to a composite core material of a paper diaper.
Background
In the prior art, the core of panty-shape diapers generally adopts the whole wood pulp material to constitute, because the core that the whole wood pulp constitutes produces the phenomenon that the lump is stuck together easily in the use, still can produce the problem of fault with the core after stretching vertically and horizontally moreover, the comfort level when reducing panty-shape diapers and wearing influences the use of panty-shape diapers, and the urine absorption rate and the anti-infiltration volume of core also are the difficult problem that must overcome simultaneously, consequently need make improvement and improvement to the core of panty-shape diapers.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides a composite core material of a paper diaper and a manufacturing method thereof.
The technical scheme adopted by the invention for solving the technical problems is as follows: the composite core material for the paper diaper comprises fluffy non-woven fabric, a high-molecular water-absorbing material and dust-free paper, wherein wood pulp fiber is embedded in the bottom layer of the fluffy non-woven fabric.
Wherein: the upper surface and the lower surface of the fluffy non-woven fabric are respectively provided with a high-molecular water-absorbing material and dust-free paper which are uniformly distributed.
Wherein: the high-molecular water-absorbing material and the dust-free paper are bonded through the hot melt adhesive layer.
Wherein: the thickness of the fluffy non-woven fabric is 2-5 mm.
Wherein: the density of the high polymer water absorption material is 50-150 g per square meter.
Wherein: the thickness of the dust-free paper is 0.2-0.5 mm.
Wherein: the length of the wood pulp fiber is 0.8-1.2 mm, and the density of the wood pulp fiber is 5-15 grams per square meter.
Wherein: the thickness of the hot melt adhesive layer is 0.08-0.15 mm.
A method for manufacturing a composite core material of a paper diaper comprises the following steps:
a. smashing the wood pulp fibers by a pulverizer to enable the length of the wood pulp fibers to be between 0.8 and 1.2 millimeters;
b. placing the fluffy non-woven fabric in a sealed space, and spraying the broken wood pulp fibers on the fluffy non-woven fabric by using an air compressor under the pressure of 20 kilopascals;
c. spraying the high-molecular water-absorbing material on the fluffy non-woven fabric with the density of 50-150 g per square meter;
d. meanwhile, spraying the hot melt adhesive on the high polymer water absorbing material with the thickness of 0.08-0.15 mm;
e. adhering the dust-free paper on a high molecular water absorption material;
f. c, reversing the fluffy non-woven fabric, and repeating the steps c, d and e;
g. and heating and pressurizing the finished product, cooling, rolling and cutting to obtain the composite core material.
The invention has the beneficial effects that: this composite core material effectively avoids producing the phenomenon that the conglomeration sticks together in the use, solves the fault phenomenon after stretching about freely and quickly simultaneously, improves close skin nature and comfort level, and after the wood pulp fibre that reachs the embedding when the urine infiltrates, the urine toward spread all around for the absorption rate of urine, the imbibition time of extension polymer absorbent material reduces the anti-infiltration volume of urine simultaneously.
Drawings
The invention is further illustrated with reference to the following figures and examples.
Fig. 1 is a schematic structural view of the present invention.
Detailed Description
Referring to fig. 1, the composite core material for the paper diaper comprises fluffy non-woven fabric 1, a high polymer water absorption material 2 and dust-free paper 3, wherein wood pulp fibers 4 are embedded in the bottom layer of the fluffy non-woven fabric 1. Wherein, the upper and lower surfaces of the fluffy non-woven fabric 1 are respectively provided with a macromolecule water-absorbing material 2 and dust-free paper 3 which are uniformly distributed. Wherein, the macromolecule water-absorbing material 2 and the dust-free paper 3 are bonded through a hot melt adhesive layer 5.
Further: the thickness of the fluffy non-woven fabric 1 is 2-5 mm. Wherein the density of the high polymer water absorption material 2 is 50-150 g per square meter. Wherein the thickness of the dust-free paper 3 is 0.2-0.5 mm. Wherein the length of the wood pulp fiber 4 is 0.8-1.2 mm, and the density of the wood pulp fiber 4 is 5-15 g per square meter. Wherein the thickness of the hot melt adhesive layer 5 is 0.08-0.15 mm.
A method for manufacturing a composite core material of a paper diaper comprises the following steps:
a. smashing the wood pulp fibers 4 by a pulverizer to enable the length of the wood pulp fibers to be between 0.8 and 1.2 millimeters;
b. placing the fluffy non-woven fabric 1 in a sealed space, and spraying the broken wood pulp fibers 4 on the fluffy non-woven fabric 1 by using an air compressor under the pressure of 20 kilopascals;
c. spraying the high polymer water absorption material 2 on the fluffy non-woven fabric 1 with the density of 50-150 g per square meter;
d. meanwhile, spraying the hot melt adhesive on the high polymer water absorption material 2 with the thickness of 0.08-0.15 mm;
e. adhering the dust-free paper 3 on the high-molecular water-absorbing material 2;
f. reversing the fluffy non-woven fabric 1, and repeating the steps c, d and e;
g. and heating and pressurizing the finished product, cooling, rolling and cutting to obtain the composite core material.
In the present invention: the hot melt adhesive layer 5 adopts hydrophilic hot melt adhesive, and the hydrophobicity of the common hot melt adhesive is changed, so that the application mode of the hot melt adhesive and the usage amount of the spray adhesive do not influence the quick infiltration and multiple infiltration liquid passing performance of urine in the composite core body any more.
This composite core material effectively avoids producing the phenomenon that the conglomeration sticks together in the use, solves the fault phenomenon after stretching about freely and quickly simultaneously, improves skin-friendly nature and comfort level, and after the wood pulp fiber 4 of arrival embedding when the urine infiltrates, the urine toward spread all around for the absorption rate of urine, the imbibition time of extension polymer absorbent material 2 simultaneously reduces the anti-infiltration volume of urine.
And further: the composite core material is tested by normal saline according to the national standard (GBT 28004-2011 paper diaper (sheet, pad)), the speed of primary absorption and secondary absorption is 8-15 seconds, and the reverse osmosis is less than 0.5 g.
