Problems solved by technology

Slower diffusion of body fluids due to faster blockage at the receiving site, poorer dryness of the absorbent article and increased risk of leakage
[0008] Due to the above disadvantages, the amount of polymer added is limited to a certain extent. In order to improve the absorption characteristics of absorbent products, only wider and longer composite absorbent cores can be used.
The width is widened, the crotch is wider after the product is made, the wearing comfort is reduced, the length is lengthened, and the overall polymer utiliz

preparation example Construction

[0056] A preparation method of composite absorbent paper for absorbent hygienic products, comprising the steps of:

[0057] (1) The upper polymer water-absorbing resin layer 4 passes through the lower hopper and passes through the polymer isolation plate, and then sprinkles it on the surface where the high-loom non-woven fabric 2 and the upper isolation layer 1 are combined, and the upper diversion groove 41 is formed at the interval ;

[0058] (2) The high-loom non-woven fabric 2 sprinkled with the upper polymer water-absorbing resin layer 4 is glued to the upper isolation layer 1 sprayed with hot-melt adhesive on the surface, and then pressed together by pressing rollers;

[0059] (3) The lower polymer water-absorbing resin layer 5 passes through the lower hopper and passes through the polymer isolation plate, and then sprinkles it on the surface where the high-loom non-woven fabric 2 is combined with the lower isolation layer 1, and the lower diversion groove is formed at t...

Embodiment approach

[0063] Wherein, the structural diagram of the polymer isolation plate is as follows: figure 2 As shown, since the polymer water-absorbent resin generally needs to pass through the lower hopper, the polymer isolation plate is arranged below the lower hopper. The polymer isolation plate is a triangular prism, and one side of the triangular prism faces the horizontal Directly below, the realization of the different widths of the upper diversion groove and the lower diversion groove in the present invention can adjust the width of the side of the triangular prism facing the side directly below the level, and the width of this side is its The width of the corresponding upper diversion groove or the lower diversion groove, the position of the top view orthographic projection of the side is the position where the upper diversion groove or the lower diversion groove is located, and the side is inseparable from the high canopy. The vertical distance of the woven fabric is 5mm, and the...

Embodiment 1

[0082]

[0083] Among them, Nippon Shokubai W211 polymer water-absorbing resin is selected for the upper and lower polymer water-absorbing resin layers, and the performance indicators are as follows

[0084]

[0085]

[0086] Using a vibrating sieve, select a finer polymer water-absorbent resin with a particle size of 40-60 mesh as the lower polymer water-absorbent resin layer, and select a coarser polymer water-absorbent resin with a particle size of 20-40 mesh as the upper polymer water-absorbent resin layer.

[0087] Wherein, the width of the upper diversion groove is 1.5 cm, the width of the lower diversion groove is 1 cm, and one of the upper diversion grooves is located in the central area of ​​the width direction of the composite absorbent paper.

Abstract

The invention provides a composite absorbent health product absorbent paper manufacturing method .The composite absorbent health product absorbent paper manufacturing method comprises steps that, (1), upper high-molecular absorbent resin layers are distributed at a surface on which high-fluffy non-woven fabric is combined with an upper separating layer with a gap, and an upper diversion trench is formed at the gap portion; (2), the high-fluffy non-woven fabric distributed with the upper high-molecular absorbent resin layers is glued with the upper separating layer of which the surface is coated with hot melt adhesive, and the two parts are stitched and rolled; (3), lower high-molecular absorbent resin layers are distributed at a surface on which high-fluffy non-woven fabric is combined with a lower separating layer, and a lower diversion trench is formed at the gap portion; and (4), the high-fluffy non-woven fabric distributed with the lower high-molecular absorbent resin layer is glued with the lower separating layer of which the surface is coated with hot melt adhesive, and the two parts are stitched and rolled. According to the method, the structure of needed equipment is simple, operation is convenient, products manufactured by utilizing the method have properties of small dimensions, simple technology and relatively low cost, moreover, the absorption characteristic is obviously improved, and the core body utilization rate is improved.

Description

technical field [0001] The invention belongs to the field of disposable sanitary products, in particular to a preparation method of composite absorbent paper for absorbent sanitary products. Background technique [0002] The core of diapers is the core part to ensure the function of absorbing and locking water. The core of traditional diapers is made of a mixture of polymer water-absorbing materials and wood pulp, which is covered with wet-strength paper or hydrophilic spunbonded non-woven fabrics. Cotton core absorbers The thickness is relatively thick, and such a material and structure, after absorbing water, the water is easy to accumulate in the water injection part and is not easy to spread. Due to the influence of gel retardation, the utilization rate of polymer water-absorbing materials is low, and the water-locking ability also has certain limitations. At the same time, Because the structure of this material is relatively loose, once it absorbs water, it will form lu...
