MOLDED HOOK-AND-LOOP FASTENER EXCELLENT IN TEMPORARILY FASTENING FUNCTION

PROBLEM TO BE SOLVED: To provide a molded hook-and-loop fastener which does not cause rigid engagement at temporarily fastening, and can obtain a large engagement force after final fastening.SOLUTION: In a hook-and-loop fastener in which a large number of male-type engagement elements are erectly arranged on a surface of a plastic base board, the male-type engagement elements have stems erecting from the plastic base board, and engagement protrusions protruding from the stems toward sideways. A height (H) of the male-type engagement element from the base board is 1.6 to 2.6 mm, and a ratio (D/H) of a length (D) from the most apex part of the male-type engagement element up to a protrusion lower end with respect to the height (H) of the male-type engagement element from the base board is 0.35 to 0.75. The male-type engagement elements have adhesion prevention protrusions protruding to a direction separating from the base board at an upper part rather than the engagement protrusions, the density of the engagement elements is within a range of 20 to 50 pcs/cm, and a base board covering rate of the male-type engagement elements is 25 to 45%.SELECTED DRAWING: Figure 1 【課題】仮止め時に強固な係合が生じることがなく、本止めした後には高い係合力が得られる成形面ファスナーを提供する。【解決手段】プラスチック基板の表面に多数の雄型係合素子が立設された面ファスナーであって、該雄型係合素子が、該プラスチック基板から立ち上がるステムと同ステムからサイドに突出する係合用突起を有しており、基板からの該雄型係合素子の高さ（Ｈ）が１．６〜２．６ｍｍであり、基板からの該雄型係合素子の高さ（Ｈ）に対する該雄型係合素子の最頂部から該突起下端部までの長さ（Ｄ）の比（Ｄ／Ｈ）が０．３５〜０．７５であり、該雄型係合素子が、基板から遠ざかる方向に突出するくっつき防止用突起を係合用突起より上に有しており、係合素子密度が２０〜５０個／ｃｍ２の範囲であり、かつ該雄型係合素子の基板被覆率が２５〜４５％である成形面ファスナー。【選択図】図１
