AI Technical Summary
Technical Problem
While existing disposable hygiene products may have deodorizing and odor-removing functions, the use of activated charcoal or scented materials is costly and affects the absorption rate and amount.
Method used
Activated carbon, activated alumina, and polyacrylamide are used as the adsorption structure, mixed with the absorption layer, and the proportions are strictly controlled. They are embedded in the absorption layer or on the surface to form a uniform distribution, avoiding the traditional layered setup and reducing the amount of polymer added.
Benefits of technology
It effectively removes urine odor, increases absorption capacity, does not affect absorption rate, reduces material costs, and avoids leakage of adsorption materials.
