Embodiment 1

[0023] refer to figure 2 and image 3 , a process for preparing an absorbent article leak-proof partition, comprising the following steps:

[0024] 1) Unwind the finished roll-shaped water-repellent non-woven fabric 1, define the extension along the unwinding and conveying direction of the water-repellent non-woven fabric 1 as the longitudinal direction Y, and extend along its width direction as the transverse direction X;

[0025] 2) Unwind and transport two volumes of processed elastic bands 2 side by side. The stretch ratio of the elastic bands 2 is 1.5 times. Spray glue on the elastic bands 2 at intervals through a spray gun, and compound the elastic bands 2 on the On the water-repellent non-woven fabric 1, the composite area a is located in the transverse middle of the water-repellent non-woven fabric 1, and the area compounded by spraying glue is the first sizing area b, and two adjacent first sizing areas along the longitudinal direction Y are The distance between th...

Embodiment 2

[0031] refer to Figure 4 and Figure 5 , a process for preparing an absorbent article leak-proof partition, comprising the following steps:

[0032] 1) Unwind the finished roll-shaped water-repellent non-woven fabric 1, define the extension along the unwinding and conveying direction of the water-repellent non-woven fabric 1 as the longitudinal direction Y, and extend along its width direction as the transverse direction X;

[0033] 2) Unwind and transport two volumes of processed elastic bands 2 side by side. The stretch ratio of the elastic bands 2 is 1.5 times. Spray glue on the elastic bands 2 at intervals through a spray gun, and compound the elastic bands 2 on the On the water-repellent non-woven fabric 1, the composite area a is located in the transverse middle of the water-repellent non-woven fabric 1, and the area compounded by spraying glue is the first sizing area b, and two adjacent first sizing areas along the longitudinal direction Y are The distance between t...

Abstract

The present invention relates to the field of disposable absorbent articles, in particular to a preparation process for leak-proof partitions of absorbent articles, which mainly solves the problems of poor comfort and poor leak-proof effect of leak-proof partitions in the prior art, and includes the following steps: 1 ) Water-repellent non-woven fabric unwinding; 2) Elastic shrinkage material unwinding, elastic shrinkage material is sprayed with glue at intervals through a spray gun, and elastic shrinkage material is compounded on the water-repellent non-woven fabric; 3) Water-repellent non-woven fabric is sprayed through a spray gun On the left side area of ​​the front side of the cloth and near the elastic shrinkage material, spray glue continuously along the longitudinal direction; 4) turn the left side area of ​​the water-repellent non-woven fabric down along the boundary between the left side area and the second sizing area 5) Spray glue on the reverse side of the left side of the water-repellent non-woven fabric that is not covered by the second sizing area through a spray gun, and then apply the right side of the water-repellent non-woven fabric along its right side to the second sizing area. The boundary of the two sizing areas is folded downwards.

Description

technical field [0001] The invention relates to the field of disposable absorbent articles, in particular to a preparation process for leakproof partitions of absorbent articles. Background technique [0002] Disposable absorbent articles such as feminine sanitary napkins, adult incontinence disposable diapers, disposable diapers, training diapers, and the like are well known. The primary function of this type of disposable absorbent article is to absorb and contain bodily exudates, which are also used to prevent bodily exudates from soiling, wetting or otherwise soiling clothing or other articles that come into contact with the wearer. [0003] In order to prevent body excrement from leaking from the lateral sides of the disposable absorbent article, leak-proof partitions are usually arranged on the lateral sides of the absorbent article. Currently, refer to figure 1 As shown, most of the leak-proof partitions of diapers are adhered to the middle part of the width directi...
