LOOP MATERIAL FOR HOOK AND LOOP FASTENERS

摘要

Presently described are loop materials comprising continuous multi-filament textured yarns intermittently bonded to a backing. In one embodiment, the yarn has a denier of less than 50, an energy at break of at least 60 joules/g, and an elongation of less than 45%. The multi-filament textured yarns preferably have a basis weight of no greater than 10 gsm and in some embodiments no greater than 5 gsm. In another embodiment, the loop material has a basis weight of no greater than 5 gsm and is characterized by having a ratio of shear strength to yarn basis weight of at least 300 g(f)/(g/m2). Such loop material preferably comprises a yarn having a denier of less than 50.
