CONSTITUTION:Any of synthetic fibers, semi-synthetic fibers, regenerated fibers and natural fibers are usable as the fibers of the web forming the loops and are preferably thermally shrinkable acrylic fibers, polyamide fibers and acrylic fibers. The web to be needled may be a web of a single or multiple layers. The fineness of the fibers of the web may be preferably >=1 denier and more particularly preferably >=3 denier. The loops of the female material formed by needle punches which are higher in density and are larger in quantity are more preferable in terms of joining force to a male material. The height of the loops is preferably >=0.3mm and more preferably >=0.5mm. The number of the loops is preferably >=10 pieces, more particularly preferably >=30 pieces per 1cm .
