Gecko-like fasteners for disposable articles

Abstract

Disposable absorbent article having nano-fabricated fastening means having adhesive bristles disposed on a substrate wherein said bristles effectively and adhesively engage a polymeric film or fibrous web on the opposite surface. In another embodiment, an absorbent article has a gecko closure comprising a substrate, a plurality of bonded bristles rising from the substrate, the bristles having a root segment, a middle segment and a tip segment, and having a height of about 0.5 μm to About 8 mm, with a diameter greater than about 0.05 μm.

Description

technical field

[0001] The invention relates to a gecko buckle for disposable products. Background technique

[0002] Adhesive materials traditionally consist of wet, glue-like substances that are tacky to the touch and tend to leave a residue when removed. Additionally, these substances are often limited in use. For example, they are less effective in water, in a vacuum, on some plastics, on some cloths. Hook-and-loop fasteners (in this translation, "buckle" will be synonymous with "fastening (piece)") can overcome some of the shortcomings of traditional adhesive materials such as glue; Faces (i.e., two separate surfaces intended to engage each other) are required for this type of clasp to function. Magnets can also overcome some of the drawbacks of traditional glue-like bonding materials; however, magnets are limited to ferrous materials. This difficulty becomes especially pronounced when fastening disposable absorbent articles.
