Abstract: A mesh hook surface fastener does not lose engagement ability even when subjected to mold-in forming and gives only a slight feeling of something foreign. The mesh hook surface fastener contains first shape holding ribs (a21) with a relatively small protrusion height and second shape holding ribs (a22) with a relatively large protrusion height which protrude to the opposite side of hook-shaped engagement elements (B1, B2) across a base layer (A1) and are alternately arranged. The heights of the adjacent shape holding ribs (a21, a22) are different, which prevents the direct entrance of a foamable resin liquid and weakens its force. As the force weakens, foaming and curing progress more readily and, as a result, the amount of the foamable resin liquid that passes through meshes of the base layer to reach the hook-shaped engagement elements can be reduced.

Abstract: A resin sheet contains: a sheet-like substrate of a resin; and wall-like projections (W) of the same resin having a certain height and standing upright on one surface of the substrate. The wall-like projections (W) are arranged on the surface of the substrate in at least 10 parallel rows with a certain spacing, and a large number of the wall-like projections (W), which satisfy the conditions (1) to (5) described in the specification, are present in parallel on the one surface of the substrate. The resin sheet is useful as a directional male hook-and-loop fastener whose male engaging elements are unlikely to break when a force is applied thereto and which does not provide a stimulus to the skin when it touches the surface of the fastener, as a filter for separating fine particles from a fluid, and as a display resin sheet.

Abstract: A polyester woven-fabric hook-and-loop fastener has a warp yarn thickness Tb which is 0.94 times or less of a warp yarn thickness Ts. A selvage area having a constant width is present on two opposite ends, continuously in a line form in the warp direction, without misalignment in the weft direction. As a result, when the polyester woven-fabric hook-and-loop fastener is sewn onto a garment or the like, a sewing thread sewn to the selvage area is in a straight line without meandering, and thus a sewn product excellent in appearance can be obtained.

Abstract: There is provided a touch fastener that has high followability to the relative movement of portions to be engaged and does not easily separate from a mating member, and thus is usable in a wider range of applications. In the touch fastener, all the elements, that is, first strands, second strands, and engagement elements are formed of a thermoplastic elastomer. Further, the plurality of first strands and the plurality of second strands are disposed to intersect with each other, and consequently, hole portions each surrounded by the two adjacent first strands and the two adjacent second strands are provided. Accordingly, it has a high elastic function, easily stretches, and has high followability to the relative movement of portions to be engaged.

Abstract: A water-soluble male-type molded hook-and-loop fastener includes a substrate and a plurality of male-type engaging elements, arranged in rows, protruding from the substrate surface. The engaging elements have a shape rising from the substrate surface and curving mid-course in a row direction, or a shape rising from the substrate surface, branching forward and backward mid-course in the row direction and curving in the row direction, with tip portions oriented toward the substrate surface in either shape. The substrate and the engaging elements both contain a mixture of a polyvinyl alcohol, 5 to 30 parts by mass of a polyhydric alcohol- or ethylene oxide-based polymer, and 3 to 20 parts by mass of a layered inorganic particle, based on 100 parts by mass of the polyvinyl alcohol. The polyvinyl alcohol has a degree of polymerization of 300 to 700 and a degree of saponification of 60 to 80% by mole.
