摘要：
Methods for forming a touch fastening material are described as including: providing a lengthwise-incoherent layer of staple fibers supported directly on a bed of bristle tips of a brush； needling the layer of staple fibers by cycling needles through the layer of staple fibers and into the brush； then, while the needled layer of staple fibers remains supported on the brush, fusing portions of the staple fibers by at least partially melting resin of the fibers disposed outside the brush； and then pulling the layer of fibers from the brush as a lengthwise-coherent touch fastening material having exposed fastening loops pulled from between the brush bristles.
