ABSORBENT STRUCTURES AND METHODS OF MAKING ABSORBENT STRUCTURES Russian patent published in 2024 - IPC A61F13/531 

FIELD: manufacturing technology.

SUBSTANCE: absorbent structures and methods for their production are disclosed. In one embodiment, the absorbent structure can comprise a first layer, a second layer and a mixture of particles and an adhesive disposed therebetween, wherein superabsorbent particles are located at more than 400 g/m² and less than 600 g/m² and the adhesive is placed at more than 4% and less than 5% by weight with respect to the weight of the superabsorbent particles. Glue can form a three-dimensional grid comprising adhesive threads in the form of a grid with super-absorbent particles fixed inside the grid, and the adhesive threads in the form of a mesh pass substantially through the entire three-dimensional space formed by the adhesive threads in the form of a mesh and the superabsorbent particles, and wherein the absorbent structure has a SAM capture value greater than or equal to 98%, in accordance with the SAM capture test method.

EFFECT: absorbent structures and methods of making absorbent structures.
