This manufacturing method of a molded surface fastener involves a primary molding step for forming a primary molded body and a secondary molding step for compressing a provisional element of the primary molded body while heating the same. A molding apparatus is provided with a mold member comprising multiple penetration holes and multiple concave portions, whereof each penetration hole communicates to at least one concave portion; in the primary molding step, the molding apparatus is used to form a primary molded body comprising a provisional element having a primary stem portion and a pawl portion is formed from the protruded portion by compressing the provisional element. By this means, it is possible to stably manufacture a molded surface fastener that has an engaging element comprising a pawl portion that projects from the outer peripheral edge of an engaging head portion.

The composite elastic material (22) includes an elastic layer (4) and a structured film layer (15) having first and second opposing surfaces, with the second surface bonded to the elastic layer (4). The first surface of the structured film layer (15) has upstanding male fastening elements. The structured film layer (15) is gathered such that the upstanding male fastening elements point in multiple directions. The composite elastic material (22) can also be called a stretch-bonded laminate, which include an elastic layer (4) stretch-bonded to a second surface of a structured film layer (15). A first surface of the structured film layer (15), opposite the second surface, has upstanding male fastening elements. A process for making the composite elastic material (22) is also described. An absorbent article including the composite elastic material (22) is also described.

A material engagement element sheet formed from a sheet material (10) incorporates a pattern of material engagement element slots (14), each slot containing an array of material engagement elements (20) which have a tapered distal section (30), a flange section (34) and a proximal section (32) which is attached to an edge of the slots in the sheet material. The material engagement element sheet material may be a single layer of shape memory material, or the sheet material may be a composite of different layers some of which may include pre-strained shape memory materials with distinguishable activation parameters. The material engagement element slot configuration allows for the simultaneous processing of the material engagement elements. The material engagement elements may be processed such that they are in a state that is substantially perpendicular to the surface of the material engagement element sheet. The configuration of the flexible base material and the pattern of the material engagement element slots may be used in order to manufacture various material engagement element devices including a material engagement element pad device (166), a cylindrical material engagement element device (104, 105), and a spherical material engagement element device (152).

In this molded surface fastener, an engaging element includes a columnar stem portion, and micro pawl portions protruding outward from an upper end outer peripheral edge of the stem portion in a plan view of the engaging elements. A pawl width dimension of the micro pawl portions is smaller than a line segment connecting two points on the upper end outer peripheral edge of the stem portion. The micro pawl portions protrude toward a base portion. This molded surface fastener has a high peel strength and a shear strength with respect to a female surface fastener.

A molded hook surface fastener having a base plate and a large number of hook engaging elements projecting from a surface of the base plate, wherein both the base plate and the hook engaging elements is made of a resin mixture comprising polybutylene succinate (A) as a continuous phase and starch (B) as a dispersed phase, and satisfying the following requirements (1) to (3) simultaneously: (1) the dispersed phase comprises polyvinyl alcohol (C); (2) the starch (B) comprises a modified starch, and an amylose content of the starch (B) is 45% by weight or more; and (3) the hook engaging element tapers from a surface of the base plate toward a distal end portion and gradually bends from its middle such that the distal end portion faces a direction slightly approaching the surface of the base plate,
is produced without breaking the hook engaging element during the pultrusion molding and is decomposed in the natural environment and does not bring about environmental destruction when discarded.

A vehicle cover assembly comprising; a flexible cover; one or more side rails; and a fastener assembly that is secured to a vehicle bed comprising; a cover fastener that is on one or more edge regions of the flexible cover; and a side rail fastener with one or more rows of fasteners comprising; a plurality of dual hooks on the base that releasably connect with the cover fastener of the flexible cover; and a plurality of spacers between the plurality of dual hooks.

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.

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.

Aspects disclosed herein relate to forming on a substrate fastener elements suitable for use in touch fastener by employing vibration forming methods. The processes described provide for a greater flexibility in manufacturing than prior methods and overcome certain limitations in prior forming techniques. Further, the product made can embody a variety of different configurations suitable for a given application. Employing vibration forming methods, such as ultrasonic forming methods, allows for the use of a wider variety of substrate material than materials used with convention methods of touch fastener formation.
