A fastener member for mechanical affixation to a structure includes a base having first and second sides, a plurality of fastening elements integrally formed and extending from a first side of the base, and at least one affixation element extending from the second side of the base and arranged to mechanically affix to an attachment opening of a structure. A system includes a structure and a fastener member for mechanical affixation to the structure. A method includes affixing the fastener member to a structure.

A male touch fastener product with a resin surface and an array of spaced-apart male touch fastener elements carried on the surface. Each touch fastener element has a stem extending from the surface and a head disposed at a distal end of the stem and extending laterally from the stem to a distal edge overhanging the surface. The head, stem and surface form a contiguous mass of resin, the head. The distal edge has multiple toes extending laterally outward and varying in shape and size about the edge, with adjacent toes having facing, free-form resin surfaces defining crevices therebetween. The fastener element is particularly flexible and engages with very fine fibers.

A loop surface fastener in which numerous looped engaging elements formed from loop yarns inserted in parallel to ground warp yarns are provided upright on one side of a base fabric formed from ground warp yarns and ground weft yarns satisfies all the following requirements 1) to 3). 1) The loop yarn is a multi-filament yarn formed by bundling 5 to 9 filaments of 30 to 45 decitex. 2) The density of the looped engaging elements is in a range of 100 to 200/cm.sup.2. 3) Loop surfaces of the looped engaging elements are substantially facing in the same direction and the loop surface facing direction is a ground weft yarn direction.

A method for forming a double-sided loop strap includes: receiving a continuous longitudinal strip of loop material including a strip-form base bearing a field of upstanding loops on a fastening side of the strip bounded by opposite longitudinal edges, folding each of the longitudinal edges away from the fastening side, such that the base overlaps itself, and securing the folded edges in place by permanently bonding together overlapped areas of the base to form the double-sided loop strap.

Embodiments related to a touch fastener and its methods of manufacture and use are disclosed. In one embodiment, the touch fastener may include a substrate with a first portion and a second portion displaceable relative to the first portion. A first fastening element may be formed in the first portion. When the first portion is displaced relative to the second portion, a force and/or moment generated by the displacement may cause the first fastening element to be deployed.

The present invention addresses the problem of providing a hook and loop fastener that not only has excellent engaging properties but is also flexible, generates little ripping noise when the male part and female part are separated, is excellent for sewing to fabric or the like, and is very durable, and a textile product comprising the hook and loop fastener. A hook and loop fastener comprises a fabric A that has a resin layer and a napped fabric B that has a resin layer containing a napped portion and a ground structure portion.

A method for forming a double-sided loop strap includes: receiving a continuous longitudinal strip of loop material including a strip-form base bearing a field of upstanding loops on a fastening side of the strip bounded by opposite longitudinal edges, folding each of the longitudinal edges away from the fastening side, such that the base overlaps itself, and securing the folded edges in place by permanently bonding together overlapped areas of the base to form the double-sided loop strap.

Provided is a method of producing a layered article by which a sufficient production speed can be achieved, and preferably, a variation in fusion strength can be suppressed and hence a variation in product quality can be reduced. The method of producing a layered article of the present invention includes fusing at least part of a single-layer body or a laminate including at least one layer including a non-woven fabric of fiber having a fiber diameter of 100 m or less through ultrasonic welding.

Provided is a layered article including at least one layer including a non-woven fabric of fiber, the layered article having sufficient flexibility and being capable of achieving a satisfactory touch feeling. Also provided is a hook-and-loop fastener including the layered article of the present invention. Also provided is a sanitary article including the layered article of the present invention. The layered article of the present invention includes at least one layer including a non-woven fabric of fiber, in which: the layered article has a fused portion; and the layered article has an index A, which is represented by the equation (1), of 0.9010.sup.6 m.sup.3/g or less: A=T/G (1) where T represents a thickness (unit: m) of the fused portion and G represents a basis weight (unit: g/m.sup.2).

A method for producing a backsheet for absorbent sanitary articles provided with hook-and-loop fasteners, comprising the steps of: advancing a continuous web of fibrous material without support at a first speed, cutting the continuous web of fibrous material in a transverse direction so as to form sections of fibrous material, accelerating the sections of fibrous material at a second speed greater than said first speed, welding said sections of fibrous material spaced apart at constant intervals onto a continuous non-woven support web advancing at said second speed, so as to convert said sections of fibrous material into frontal tapes of loop-material for hook-and-loop fasteners, and fixing a continuous impermeable film to said continuous non-woven support web with said frontal tapes of loop-material, so as to form a continuous backsheet web provided with frontal tapes of loop-material spaced apart at constant intervals.
