摘要： A touch fastener strip includes a pair of longitudinal barrier walls each extending upward from a base, a plurality of lateral barrier walls each extending upward from the base and between facing surfaces of the barrier walls, thereby defining one or more fastening cells, and a pair of wave walls each extending upward from the base and outboard the barrier walls thereby defining a relief space. Each wave wall has a wave shape having rising and falling edges, at least one of the edges having a slope in the range of 3° to 65°. In some cases, the wave shape has a duty cycle of 40% to 60%, and may include a sine wave, a triangle wave, a ramp wave, and/or a bi-modal wave having two different peak points in a given cycle of the shape. In one example application, the strip may be anchored in a foam cushion product.
