LOOP SURFACE FASTENER HAVING EXCELLENT POSITIONING FUNCTION

摘要

In a loop surface fastener, numerous looped engaging elements (3) formed from loop yarns (2) inserted in parallel to ground warp yarns are provided upright on one side of a base fabric formed from ground warp yarns and ground weft yarns (1), wherein all the following requirements 1) to 3) are satisfied: 1) the density of the looped engaging elements (3) is in a range of 100 to 200/cm 2 ; characterized in that 2) the loop yarn (2) is a multi-filament yarn formed by bundling 5 to 9 filaments of 30 to 45 decitex; 3) loop surfaces of the looped engaging elements (3) are substantially facing in the same direction and the loop surfaces of the looped engaging elements (3) face in directions in a range of ±30° with respect to a direction perpendicular to the ground weft yarn direction (1).
