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 surface fastener formed of a synthetic resin and in which a base with a 0.1 to 0.9 mm thickness and engagement element groups including engagement elements with a 0.2 to 0.8 mm protrusion height are integrally molded, and engagement element rows are composed of the plural engagement elements arranged in a row direction and each protruding independently. A cushioning member is covered with a covering member via the surface fastener. A resistance value of the surface fastener by itself as measured by a handle-o-meter method conforming to the JIS L 1096 E method is 80 to 150 g, whereas a load-deflection characteristic when a pressure is applied to an overlapping portion of the stacked surface fastener and cushioning member by a pressure plate with a 30 mm diameter approximates a similarly measured load-deflection characteristic of the cushioning member by itself.

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.
