Embodiment 1

[0035] refer to Figure 1 to Figure 4, a diaper, comprising a diaper body, the diaper body includes a surface layer 1, a flow diversion layer 2, an absorption layer 3 and a bottom layer 4 that are sequentially stacked from top to bottom, and the flow diversion layer 2 includes an upper flow diversion layer 21 And the lower diversion layer 22 located below the upper diversion layer 21, the upper diversion layer 21 and the lower diversion layer 22 are hot-air non-woven fabrics, and the upper diversion layer 21 forms several first diversion layers through hydrophilic treatment. A hydrophilic region 211, each of the first hydrophilic regions 211 is arranged at equal intervals, and the lower guide layer 22 forms a plurality of second hydrophilic regions 221 through hydrophilic treatment, and each of the second hydrophilic regions 221, etc. The spacing is set, the area of ​​the second hydrophilic region 221 is larger than the area of ​​the first hydrophilic region 211, the gap betwe...

Embodiment 2

[0046] A paper diaper, which differs from Example 1 in that the process parameters of the preparation steps and the contents of each component are different.

[0047] The preparation of diapers includes the following steps:

[0048] S1. Preparation of surface layer

[0049] Add 3-(2-hydroxy-2-propyl)phenol and N-methacrylamine into the reaction kettle with solvent, stir and mix evenly, then add polyoxymethylene into the reaction kettle, raise the temperature to 65°C for 5 hours, reduce Pressure distillation obtains reaction monomer, and the mass ratio of described 3-(2-hydroxyl-2-propyl) phenol, N-methacrylamine, polyoxymethylene is 135:220:90, and reaction monomer, azobis Dimethyl isobutyrate was dissolved in a toluene solution, and then 1,5-divinylhexamethyltrisiloxane was added in a nitrogen atmosphere at a temperature of 60°C, and refluxed for 4 hours to obtain a hygroscopic polymer. The added amounts of dimethyl azobisisobutyrate and 1,5-divinylhexamethyltrisiloxane are...

Embodiment 3

[0057] A paper diaper, which differs from Example 1 in that the process parameters of the preparation steps and the contents of each component are different. The preparation of diapers includes the following steps:

[0058] S1. Preparation of surface layer

[0059] Add 3-(2-hydroxy-2-propyl)phenol and N-methacrylamine into the reaction kettle with solvent, stir and mix evenly, add polyoxymethylene into the reaction kettle, raise the temperature to 70°C for 4 hours, reduce Pressure distillation obtains reaction monomer, and the mass ratio of described 3-(2-hydroxyl-2-propyl) phenol, N-methacrylamine, polyoxymethylene is 140:228:96, and reaction monomer, azobis Dimethyl isobutyrate was dissolved in toluene solution, and then 1,5-divinylhexamethyltrisiloxane was added under nitrogen atmosphere and temperature conditions of 65° C., and refluxed for 5 hours to obtain a hygroscopic polymer. The added amounts of dimethyl azobisisobutyrate and 1,5-divinylhexamethyltrisiloxane are re...

Abstract

The invention relates to the field of hygienic products, and provides a paper diaper. The paper diaper comprises a paper diaper body, wherein the paper diaper body comprises a surface layer, a flow guide layer, an absorption layer and a bottom layer which are sequentially laminated from top to bottom; the surface layer is prepared from bamboo fibers and skin-core type fibers as raw materials by a spunlace method; the skin layer of the skin-core type fibers contains polyester and an antibacterial agent; the core layer contains a moisture-absorbing polymer; the flow guide layer comprises an upper flow guide layer and a lower flow guide layer; the upper flow guide layer is provided with a plurality of first hydrophilic areas; the lower flow guide layer is provided with a plurality of second hydrophilic areas; the area of the second hydrophilic areas is larger than that of the first hydrophilic areas; the gap between the adjacent first hydrophilic areas is larger than that of the adjacent second hydrophilic areas; and the absorption layer comprises upper dust-free paper, an upper absorption core, an antibacterial layer, a lower absorption core and lower dust-free paper from top to bottom. The paper diaper solves the problems that the existing paper diaper does not have antibacterial activity or is poor in antibacterial effect, and adverse conditions such as eczema and red buttocks are easily caused.

Description

technical field [0001] The invention relates to the field of disposable sanitary products, in particular to a paper diaper and a preparation method thereof. Background technique [0002] Chinese patent application number: 201510729415.7 discloses a paper diaper that quickly absorbs liquid and keeps dry, including a diaper body, an elastic front waist and an elastic back waist. An absorbent core is longitudinally arranged in the middle of the diaper body. The body is made by compression molding, the absorbent core is distributed with a number of diversion protrusions, the center of the absorbent core is longitudinally pressed with a long diversion groove, and the absorbent core is composed of a surface non-woven fabric layer, a diversion Layer, first polymer water-absorbing layer, wood pulp layer, second polymer water-absorbing layer and leak-proof bottom film, the weight ratio of the first polymer water-absorbing layer to the second polymer water-absorbing layer is 3.5-4.5:1...
