ANCHORING LOOPS OF FIBERS NEEDLED INTO A CARRIER SHEET

摘要

Methods of forming a loop product (31) are provided. Methods include needling polymeric fibers (12) through a substrate (14) to form hook-engageable loop structures (48) of the fibers (12) extending from one surface of the substrate (14) and then using heat and pressure to soften and bond polymer of the fibers (12) directly to the substrate (14) and adjacent fibers (12), thereby anchoring the loop structures (48) to resist fiber pullout under fastening loads. Loop products (31) are also provided.
