An integral molded surface
fastener having minute and peculiar engaging elements, which engage with minute, thickly wooded
fiber piles securely while each engaging element secures appropriate engagement strength, shearing strength and separation strength is provided. Further, texture of a surface of the surface
fastener is improved and a height of the engaging elements protruded from a surface of a substrate is lower than a conventional type, thereby preventing the engaging elements from being fallen down by a pressing strength. At the same time, a high engaging ratio with a
mating pile piece is secured and a durability required for this kind of
fastener is satisfied. Preferably, a desired
plasticity and tearing strength of the flat substrate are secured. More specifically, a molded surface fastener having minute engaging elements of
thermoplastic resin formed together with a substrate by continuous molding is provided, the engaging elements being hook-type engaging elements each comprised of a single column portion having a substantially cross-shaped section provided by intersection of a first column portion and a second column portion and rectangular thin plate-like engaging heads extended in the shape of wings in opposite directions along the width direction of the first column portion intersecting the second column portion around a top end of the column portion, and having substantially the same width dimension as the width dimension of a top end of the second column portion.
