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.

This molded surface fastener includes: a base portion; right and left outer wall portions arranged on the upper surfaces of the base portion; a plurality of engaging elements arranged between the right and left outer wall portions; and right and left magnetic wall portions arranged between the outer wall portions and the engaging elements. This molded surface fastener is molded by melting and integrating first synthetic resin and second synthetic resin that contains magnetic particles. At least each upper end part of the outer wall portions is formed only of the first synthetic resin, while at least each upper end part of the magnetic wall portions is formed only of the second synthetic resin. Consequently, the right and left magnetic wall portions can be formed into predetermined shapes in a stable manner.

A sheet-form fastener product has a flexible substrate such as a lightweight non-woven fabric and a resin layer covering only part of one side of the flexible substrate and leaving a region of the flexible substrate exposed. The resin layer carries multiple touch fastener elements each having a resin stem extending integrally from the layer away from the flexible substrate to an engageable head. A flexible ferromagnetic coating is bonded to the flexible substrate and extends under both the resin layer and the exposed region of the flexible substrate. The resin layer can be arranged as spaced-apart lanes or islands of resin and the coating can be arranged as spaced lanes or islands or otherwise leaving at least a portion of the substrate exposed.

The molded surface fastener has a base portion, right and left resin-intrusion-preventing wall portions standing on the base portion, and a plurality of engaging elements disposed between the right and left resin-intrusion-preventing wall portions. The resin-intrusion-preventing wall portions contain magnetic particles, and at least a part of a region formed of the resin-intrusion-preventing wall portions and the base portion has a concentration gradient portion in which a concentration of the contained magnetic particles is decreased toward at least one direction. This makes it possible to enhance the adhesion property between the part containing the magnetic particles and the part substantially containing no magnetic particles, and to suppress occurrence of cracks or the like between the containing part and the non-containing part of the magnetic particles at the time of manufacturing the molded surface fastener and at other times.

1. Touch fastener part

2. A touch fastener part having a first substrate tape (10) having hooking elements (12) arranged on one side thereof, and having a second substrate tape (16) which, connected to the first substrate tape (10), has a connection means (20) on its side facing away from the hooking elements (12), wherein the second substrate tape (16) is wider than the first substrate tape (10) and at least one free lateral edge area (22) of the second substrate tape (16) projects beyond the adjacent longitudinal edge of the first substrate tape (10), and wherein the two substrate tapes (10,16) can be bent along and transversely to their longitudinal orientation, is characterized in that at least one free side edge area (22) of the second substrate tape (16) is provided with a weakening of resistance (27) in such a way that bending the two substrate tapes (10,16) transversely to their longitudinal orientation is facilitated.

The invention relates to a workpiece having a shape produced by thermoforming from at least one sheet (3) of plastic material, such as polycarbonate, and at least one applied element (6, 8; 7, 9) that is applied to the at least one sheet and secured there, characterised in that the securing of the at least one applied element to the at least one sheet takes place at least partially by means of crimping.

There is provided a fastening tape. A plurality of fastening cells on a surface of an elongated substrate. Each of at least some of the fastening cells includes: a fastening element array; one or more barriers at least partially surrounding the fastening element array; at least one slit provided in an upper portion of at least one of the one or more barriers; and a fastening element at least partially filling the slit. At least some of the fastening cells which are adjacent to each other in a longitudinal direction are separated from each other by an open space extending across the substrate in a lateral direction. The fastening element extends inward of the respective fastening cells in a direction away from a respective one of the open spaces.

The molded surface fastener has a base portion, right and left resin-intrusion-preventing wall portions standing on the base portion, and a plurality of engaging elements disposed between the right and left resin-intrusion-preventing wall portions. The resin-intrusion-preventing wall portions contain magnetic particles, and at least a part of a region formed of the resin-intrusion-preventing wall portions and the base portion has a concentration gradient portion in which a concentration of the contained magnetic particles is decreased toward at least one direction. This makes it possible to enhance the adhesion property between the part containing the magnetic particles and the part substantially containing no magnetic particles, and to suppress occurrence of cracks or the like between the containing part and the non-containing part of the magnetic particles at the time of manufacturing the molded surface fastener and at other times.

Provided is a molded surface fastener capable of stably having high engaging strength with respect to a loop member. The molded surface fastener of the present invention includes a base portion and a plurality of engaging elements provided with a stem portion and an engaging portion, and is formed of synthetic resin containing lubricant at 0.15 wt % or more and 1.00 wt % or less. A top end surface of the engaging element is formed to be flat, and the engaging portion has a hanging portion which hangs down obliquely downward toward the base portion.

Described is a fastening tape that includes a plurality of attachment portions extending upwardly from a bottom portion of the fastening tape. The fastening tape also includes at least one inner wall disposed adjacent to at least some of the plurality of attachment portions and at least one outer wall offset from the at least one inner wall such that a cavity is disposed between the at least one inner wall and the at least one outer wall. Finally, the fastening tape includes an injected foam member disposed in the cavity.
