Problems solved by technology

Its disadvantages: First, the arc-shaped veneer is a convex arc-shaped veneer, the purpose is to guide the menstrual fluid from the middle to the two sides through the guide groove, and it does not solve how to effectively reduce the contact surface between the female genitals and the sanitary napkin , and did not solve the problem of menstrual fluid storage and absorption; second, it did not solve the problem of elastic anti-side leakage

Embodiment 1

[0019] Embodiment 1: with reference to attached Figure 1-3 . A crepe-type anti-side leakage arc-shaped elastic sanitary product veneer, in which the two sides of the elastic film 2 are respectively hot-pressed and composited with the non-woven fabric strip 1 in a stretched state, and then the non-woven fabric strips on both sides of the elastic film are hot-pressed and laminated It is double-layer folded, and the elastic film springs back and resets to force the non-woven fabric strips located between the two elastic film strips to form crepe side leakage-proof side walls, and the elastic film 2 located between the non-woven fabric strips is in a concave arc shape. The stretch rate of the elastic air-permeable film is between 50% and 500% including the end values.

Embodiment 2

[0020] Embodiment 2: On the basis of Embodiment 1, the elastic membrane is an elastic perforated air-permeable membrane, and the membrane surface air-permeable holes of the elastic perforated air-permeable membrane are tapered holes 3 .

Embodiment 3

[0021] Embodiment 3: On the basis of Embodiment 1, the elastic membrane is an elastic gas-permeable membrane. The elastic air-permeable film is formed by stretching an elastic film composed of organic components and inorganic components.

Abstract

The invention relates to crimped anti-side-leakage arc-shaped elastic hygiene product facing and a production line. After the two sides of an elastic membrane in a stretched state are combined with non-woven cloth strips in a hot-pressing mode respectively, the elastic membrane resiles to restore, and the non-woven cloth strips on the two sides of the elastic membrane are forced to form crimped anti-side-leakage side walls, wherein the elastic membrane is in a concave arc shape. The crimped anti-side-leakage arc-shaped elastic hygiene product facing and the production line have the advantages that the non-woven cloth strips can be combined with the two sides of the elastic breathable membrane without hot-melt adhesive, and it is ensured that the breathability of the elastic breathable membrane and the non-woven cloth strips is not influenced by hot-melt adhesive; after the two sides of the elastic breathable membrane in a stretched state are combined with the non-woven cloth strips respectively, the elastic breathable membrane resiles, and the non-woven cloth strips are forced to form the needed elastic crimped anti-side-leakage side walls along with resilient restoration of the elastic breathable membrane, wherein the walls have the function of stopping liquid from flowing, greatly reduce the contact area of the sanitary towel or paper diaper facing and the human body and greatly improve the comfort of the human body.

Description

technical field [0001] The invention relates to a kind of non-woven fabric strips that can be composited on the elastic breathable membrane under the stretched state without hot melt adhesive or stretching of the non-woven fabric, and after the elastic breathable membrane rebounds and resets A crepe type anti-side leakage curved elastic veneer for sanitary products with anti-side leakage side walls and a production line are mainly used for sanitary napkin veneers and diaper crotch veneers, and belong to the field of sanitary product manufacturing. Background technique [0002] CN204521234U, the name "a kind of leak-proof sanitary napkin", includes a sanitary napkin body (100), the upper surface of the sanitary napkin body is provided with a liquid-conducting layer, and the middle part of the liquid-conducting layer protrudes upwards along the length direction to form an arc-shaped veneer; At least one liquid guide groove is provided on the outer periphery of the veneer, and ...
