Latest Patents

Kearney's latest patents include innovative designs for nonwoven thermal bonding patterns with low fuzz. One patent describes a nonwoven fabric that features a pattern of thermal bonds with anti-fuzz properties. This design adheres to specific conditions, such as having thermal bonds arranged in parallel rows at a pitch angle ranging from 0.5° to 15° relative to the machine direction or cross-machine direction. Additionally, the bonding area of these thermal bonds constitutes between 17% to 30% of the nonwoven's total area. The pattern also incorporates larger and smaller bonds with varying individual areas, as well as elongated bonds with different major directions.

Another patent focuses on a nonwoven fabric that extends in both machine and cross-machine directions, with fibers bonded through a specific pattern of thermal bonds. This design includes larger bonds with an individual area of at least 1.0 mm and smaller bonds with an area of less than 1.0 mm. Notably, there are at least as many smaller bonds as larger ones, with a preferred ratio of about two smaller bonds for every larger bond.
