摘要:
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/cm2. 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.
摘要:
A hook surface fastener excellent in the heat resistance, flame resistance, retention of hook shape, and pull-out resistance of hook engaging elements (fibers). The hook surface fastener is composed of a base fabric and the hook engaging elements formed on the base fabric. The base fabric is a woven fabric composed of warp yarns, weft yarns and fibers constituting the hook engaging elements. The warp yarns and the fibers constituting the hook engaging elements are polyphenylene sulfide fibers. The weft yarns are substantially non-twisted, paralleled yarns of polyphenylene sulfide fibers and heat-fusible fibers having a melting point or softening point each being 230° C. or lower. The polyphenylene sulfide fibers constituting the hook engaging elements have a crystal orientation of 85.0 to 90.0% and a crystallinity of 32.0 to 42.0% so that the retention of hook shape is good. The fibers constituting the hook engaging elements are anchored to the base fabric by fusion of the heat-fusible fibers. Therefore, the pull-out resistance of the hook engaging elements (fibers) is good even if a resin coat layer is substantially not provided on the back surface of the base fabric. A hook surface fastener substantially free from the resin coat layer has a good heat resistance and flame resistance.
摘要:
A temperature tolerant hook and loop attachment, a method of forming a sheet of the hooks and, a method of insulating the skin of a flight vehicle. Temporary loops are formed in a fabric containing temperature tolerant fiber tows, e.g., the tows may be carbon, a metal, a carbide such as carbon silicide, a nitride, or an oxide. The temporary loops are stiffened (e.g., with resin, metal or ceramic), and severed to form temperature tolerant fiber composite hooks. The sheet may be cut and permanently applied, for example, to the skin of a spacecraft or aircraft. A fibrous material, e.g., fibrous insulation or batting, may be pressed in place or formed into the hooks, or the fibrous material may be attached to another structure and pressed in place for a temperature tolerant hook and loop attachment.
摘要:
Provided is a fabric for binding and fastening, including a first cloth material and a second cloth material. The first cloth material has a first base cloth, and a plurality of curved hook structures is provided on a surface of the first base cloth. The second cloth material has a second base cloth, and a plurality of loop structures is provided on a surface of the second base cloth. The hook structures of the first cloth material and the loop structures of the second cloth material are embedded in each other for binding. The fabric is applicable to two objects that need to be bound and fastened, avoiding the two objects from moving freely.
摘要:
A flexible hook fastener member having a hook density of 80 to 200 per cm2 and causing little damage to cooperating loop fastening elements. The loops for forming hook fastening elements are produced by thin monofilaments having a fineness of 100 to 200 deniers. The monofilament for forming the hook fastening elements are in reverse phase relation to the adjacent ground warps with respect to the ground wefts.
摘要:
A method is disclosed for producing the hooked surface of a hook- and loop-type fastener by treating a starting fabric material having a pile of upstanding threads. The treatment comprises impregnating the threads and pile with a liquid plastic monomer having the capability of being converted by the application thereto of a suitable form of energy to a flexible solid, applying heat or other suitable form of energy to the underside of the starting material to set the lower portion of the threads into a relatively permanent and stiffened shape and then subjecting the other side of said starting material simultaneously to a pressure and heat or other suitable form of energy to bend and set the upper portions of the threads into the form of hooking elements.
摘要:
A connection system has a first adhesion segment, on which a first connection region is formed, a second adhesion segment, on which a second connection region is formed, and a solidifiable liquid connection substance for connecting the two adhesion segments in a material fit, wherein at least one of the two connection regions is formed flexibly, such that, when the liquid connection substance is introduced between the two connection regions which are opposite one another in an assembly arrangement of the two adhesion segments, a material connection is formed between the two connection regions automatically as a result of the elastocapillary effect via the liquid connection substance.
