Title:
【発明の名称】吸収製品における使用のための機能性吸収材料の表面の改変
Document Type and Number:
Japanese Patent JP3466628
Kind Code:
B2
Abstract:
The method relates to functional absorbent materials that are profiled through cutting and heating to form flow channels, and in one embodiment to form bellows which rise above the flow channels. Additionally, the flow channels which are partially cut into an absorbent material may also function as hinge means for that material as regards bending and conformity of fit. In one embodiment, functional absorbent material is provided with discrete heating and cutting, e.g., by a laser, by which channels and bellows are simultaneously formed. In another embodiment using a discrete heating and cutting means, e.g., a laser, is used to provide channels partially through the surface of a functional absorbent material.
