Title:
ABSORBENT HYGIENE PRODUCT AND CORE THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/211710
Kind Code:
A1
Abstract:
An absorbent hygiene product and a core thereof. The absorbent core comprises at least one superabsorbent resin layer (3), at least one cotton fiber layer (2), and at least one layer of dust-free paper (1) disposed therebetween. The present invention adds the dust-free paper (1) at a middle position, such that when liquid penetrates from the surface layer, it reaches the dust-free paper (1) at the middle. The dust-free paper (1) separates the upper and lower absorbent layers, and guides and spreads the liquid such that the liquid forms a guide flow channel thereon, such that the liquid can evenly disperse on the lower absorbent material, thereby ensuring that the entire absorbent core performs liquid absorption, and avoiding partial seepage or leakage caused by excessive liquid concentration.
