To obtain a material which is used for the loop members of hook-and- loop fasteners, scarcely generates fuzzes, wrinkles and the like, has an excellent repeated engagement strength and excellent flexibility, and is useful for living materials and the like, by forming loops on the surface of a filament non-woven fabric, imparting an adhesive and then fixing the loops under specific conditions.
This material for the loop members of hook-and-loop fasteners is obtained by applying a needle-punching treatment to a filament non-woven fabric (METSUKE: preferably 30-300 g/m2) comprising polyethylene terephthalate filaments to form loops in a density of 10-100 loops/cm2 on at least one surface of the nonwoven fabric, imparting an adhesive to the nonwoven fabric, and then melting and compacting the non-woven fabric by a ultrasonic wave means, a heat-pressing means or the like to fix the loops. In the obtained materials for the loop members of the hook-and-loop fasteners, the area rate of the discontinuous melted and melt-compacted portions is 2-30%.
