Description

[0002] Pet paper diaper as an important article of modern pet care, is mainly used for solving pet excretion management, environmental sanitation and odor control problems. At present, the pet paper diapers on the market mostly adopt two to three layer basic structure design, and its core function depends on the combination of chemical absorption materials (such as high molecular water absorbing resin) and simple leakage prevention film. However, such traditional scheme has significant defects:

[0003] Insufficient flow guiding efficiency: the liquid absorbing layer lacks directional flow guiding structure, which is easy to cause local saturation and horizontal diffusion of liquid, and causes side leakage problem, especially poor applicability for pets with large activity;

[0004] Odor control limitation: most products rely on adding essence to cover up odor, or a small amount of activated carbon powder is mixed in the absorbing layer, and such chemical means has the risk of stimulating the respiratory system of pets;

[0005] Breathable and leakage prevention contradiction: the leakage prevention layer generally adopts dense PE film, which can block liquid exosmosis, but seriously hinders air circulation, and long-term use can easily cause pet skin to be hot and humid, and cause dermatitis;

[0006] Therefore, the utility model provides a paper diaper. UTILITY MODEL CONTENT
