Mold-in fastener products
Mold-in fastener products are made by forming a longitudinally continuous hook tape having a flexible base and an array of discrete male touch fastener elements extending from an upper surface of the base, forming a layer of flexible barrier material on the upper surface of the base, such that the male touch fastener elements are embedded in the layer of flexible barrier material, severing the flexible barrier material to form a pattern of patches of flexible barrier material spaced apart and surrounded by a continuous lattice of barrier material, stripping the lattice from the upper surface of the base to expose regions of the base between patches, and severing the hook tape along the exposed regions of the base to form individual mold-in fastener products, each having a patch of flexible barrier material surrounded by an exposed base edge region carrying male touch fastener elements.
Methods for Manufacturing Hook Fastener
A hook fastener includes a stem having two lateral edges, a first surface, and a second surface. A cap extends from an upper end of the stem, and the cap includes an upper surface, a first end, a second end, and a pair of overhanging portions. The upper surface of the cap is sloped between the first end and the second end. The first and second ends are at opposite longitudinal ends of the cap, and each overhanging portion extends in a lateral direction from the stem.
MALE TOUCH FASTENER ELEMENTS
A male touch fastener product has an array of discrete fastening elements extending from a resin base. The elements are formed by molding stems and then deforming at least a rim of a distal end of each head to form an overhanging mushroom-type fastener element. Some are deformed against a hard surface to form flat fastener elements, and others are deformed against a compliant surface and form umbrella-shaped fastener elements. The fastener element heads feature particular structural relationships that enhance their performance, particularly with low-lying fibers.

Surface bonding fastener
A surface bonding fastener for opening and closing an opening of a package comprises a first base sheet having a first surface; a second base sheet having a second surface facing the first surface; first and second blocking sheets secured to the first and second surfaces at first and second fixing ends; and plurality of first and second fastening units on first and second free ends opposite to the first and second fixing ends. The first and second fixing ends are closer to the opening of the package than the first and second free ends that are between the first and second base sheets. The first and second fastening units are arranged at intervals in a longitudinal direction and staggered in a transverse direction perpendicular to the longitudinal direction. The first and second fastening units are configured to be fastened with each other for closing the opening of the package.
Method and apparatus for producing hook fasteners
Apparatus and process are described for forming projections on a substrate for use as hook-type fasteners in touch fastening systems, wherein vibration energy may be used to soften a substrate which may be positioned between a mold and a source of vibration. The mold may include a plurality of cavities into which the softened substrate may be forced to form the projections. The substrate may comprise a film, sheet, web, composite, laminate, etc. and be useful as an attachment strip for temporary or permanent fastening. The source of vibration may be an ultrasonic horn. The process to form such projections may be operated in a continuous, semi-continuous or intermittent manner.
Molded surface fastener
An integrally moldable molded surface fastener retains practical rigidity, while having attraction force to a magnet and is prevented from being easily broken during attachment and detachment handlings to and from loop-shaped engaging elements. A first resin composition including 80% by mass or more of a thermoplastic polyester and containing no magnetic material is used in at least a part of a substrate portion, and a second resin composition containing a thermoplastic polyester, a thermoplastic polyester elastomer and a magnetic material at a certain proportion is used in at least a part of engaging elements of the molded surface fastener.
Fastening tape with injected foam gasket
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.
SURFACE FASTENER, CUSHIONING STRUCTURE, AND SEAT STRUCTURE
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.
Surface Fastener and Method of Manufacturing Surface Fastener
A surface fastener includes a base portion and a plurality of engaging elements, the base portion and the engaging elements include a thermoplastic resin at least partially including a plant-derived resin, the plant-derived resin has an MFR of 5 g/10 min or more and 30 g/10 min or less, and has a flexural modulus of 800 MPa or more and 2300 MPa or less, and, in plan view of each of the engaging elements, the engaging head portion is such that at least a part of the engaging head portion has a shape protruding outward with respect to an upper end of the stem portion. Therefore, the surface fastener can include a plurality of engaging elements. In addition, compared to the related art, it is possible to reduce the use of fossil-resource-derived resin to thereby reduce the load on the environment.
