Embodiment 1

[0055] refer to figure 1 and figure 2 ,refer to figure 1 , an absorbent article preventing side leakage, comprising an absorbent article body (for the unfolded view of the absorbent article body, please refer to the applicant's prior application CN 202682192 U), the absorbent article body includes a liquid-permeable surface layer 1, The liquid-impermeable bottom layer 2, and the absorbent core 3 placed between the liquid-permeable surface layer 1 and the liquid-impermeable bottom layer 2, define that the main body of the absorbent article has a longitudinal direction in the length direction and a transverse direction in the width direction. Leak-proof partitions 4 extending longitudinally are arranged on both lateral sides of the main body, and the body of the absorbent article outside the lateral lateral ends of the liquid-permeable surface layer 1 is provided with leg circumference elastic stretch parts 5 extending longitudinally. Specifically, the elastically stretchable...

Embodiment 2

[0072] refer to image 3 and Figure 4 , compared with Embodiment 1, the above step b also includes:

[0073] Step b1, sizing glue on the lower end faces of the two hydrophobic non-woven fabrics and the end opposite to the bonding point 1 to form bonding point 3;

[0074] b2. A hydrophilic non-woven fabric 2 is arranged below the bonding point 3, and SAP is applied on the upper surface of the hydrophilic non-woven fabric 2 to form a side-absorbing core layer;

[0075] b3. Adhesively forming the product obtained in step b2 with the bonding point three.

[0076] In this embodiment, in the above step b2, the SAP on the partition absorbent core layer 64 is arranged at intervals along the lateral direction of the second hydrophilic non-woven fabric; specifically, the partition absorbent core layer 64 is arranged along the leak-proof partition 4. Two SAPs spaced laterally; different from Embodiment 1, the structure of the covering layer 6 of this embodiment is that the side attac...

Embodiment 3

[0079] refer to Figure 5 , Image 6 , compared with embodiment two, above-mentioned step b also comprises:

[0080] Step b1, sizing glue on the lower end faces of the two hydrophobic non-woven fabrics and the end opposite to the bonding point 1 to form bonding point 3;

[0081] b2. A hydrophilic non-woven fabric 2 is arranged below the bonding point 3, and SAP is applied on the upper surface of the hydrophilic non-woven fabric 2 to form a side-absorbing core layer 64;

[0082] b3. Adhesively forming the product obtained in step b2 with the bonding point three.

[0083] Specifically, in the above step b2, the SAP on the side absorbent core layer 64 is arranged at intervals along the lateral direction of the hydrophilic nonwoven fabric two; at the same time, in the above step b, the hydrophilic nonwoven fabric is located on the hydrophobic nonwoven fabric one. The lower end of the outer part of the cloth is applied with the elastic elastic parts 5 around the legs, and then i...

Abstract

The invention relates to the technical field of hygienic product production, in particular to an application process of an absorption article capable of preventing side leakage. The application process comprises the following steps: 1, preparing a liquid-permeable surface layer; and step 1 comprises the following steps: a, taking a continuously conveyed first hydrophilic non-woven fabric, and applying glue to the end parts of two transverse sides of the lower surface of the first hydrophilic non-woven fabric to form first bonding points; b, conveying two pieces of first hydrophobic non-woven fabric above the two transverse sides of the first hydrophilic non-woven fabric in the same direction, and folding the part, located outside the first hydrophilic non-woven fabric, of the first hydrophobic non-woven fabric downwards and inwards through a folding mechanism so that the part makes contact with and adheres to the first bonding points; and c, applying glue to the end part, close to the unfolded ends, of the upper surfaces of the two pieces of first hydrophobic non-woven fabric, so as to form second bonding points. The problem that according to an existing absorption article, leakage occurs from the two sides, close to the front end and the rear end, of a leakage-proof partition edge, and consequently side leakage is caused is solved, and the production technology and related equipment are adjusted.

Description

technical field [0001] The invention relates to the technical field of hygienic product production, in particular to an application process of side leakage-proof absorbent articles. Background technique [0002] In the existing disposable absorbent articles, the elastic elastic bands around the legs are arranged between the surface layer and the bottom material. Between the bottom layers, and for the front waist area and the back waist area, at the corresponding positions of the elastic elastic elastic bands around the legs, the surface layer is not joined with the bottom layer, so there is a non-adhesive area with a certain bandwidth. The excrement of the wearer diffuses from the surface layer to both sides and leaks out from the non-adhesive area. Leaked fecal matter contaminates the wearer's clothing, rendering the disposable absorbent article ineffective. [0003] The applicant has a prior application CN 202682192 U, which discloses a disposable absorbent article, whic...
