MULTILAYER ABSORPTION CORE AND MANUFACTURING METHODS Russian patent published in 2023 - IPC A61F13/533 

Abstract RU 2799805 C1

FIELD: absorbent elements.

SUBSTANCE: method for forming the absorbent may include moving the first cover material in the machine direction, moving the reinforcement material in the machine direction, and combining the reinforcement material with the first cover material, wherein the reinforcement material has an upper side and a lower side, applying an absorbent material containing superabsorbent material particles to the upper side of the reinforcement material, moving the second coating material in the machine direction and combining the second coating material with the first coating material and the reinforcement material to form a layered structure of the first coating material, the reinforcement material and the second coating material, where the first coating material is located under the reinforcement material and the second coating material the material is located on top of the reinforcing material, and the embossing of the layered structure.

EFFECT: invention describes multilayer absorbent elements and methods for their manufacture
