Description

Technical Field

[0001] The utility model relates to the technical field of diaper production, in particular to an atomizing coating device for a breathable film layer of a diaper. Background Art

[0002] Diapers are produced by bonding multiple layers of diaper structure layers to each other through viscose. In addition to infants and young children, they are also suitable for people with moderate to severe incontinence, sick people who are bedridden and cannot go to the toilet independently, etc. The application range is wide. In addition to the waterproof layer and the absorbent core, the diaper structure layer also has a breathable film layer.
