Abstract:
The present invention pertains to a process for manufacturing high molecular weight polyethylene fibers, comprising subjecting a polyethylene tape with a weight average molecular weight of at least 500 000 gram/mole, an Mw/Mn ratio of at most 6, and a 200/110 uniplanar orientation parameter of at least 3 to a force in the direction of the thickness of the tape over the whole width of the tape. The invention also pertains to a polyethylene fiber having an Mw of at least 500 000 gram/mole, an Mw/Mn ratio of at most 6, and a 020 uniplanar orientation value of at most 55°. The use of these fibres in various applications is also claimed. The preparation of low-linear density fibers is particularly preferred.
Abstract:
Ein flexibles, umlenkbares Zugorgan (16) wird für statische und dynamische Lasten, insbesondere für Personenlifte, Warenlifte, Krane und Fahrzeuge eingesetzt. Das Zugorgan (16) umfasst wenigstens eine Litze (18) aus zugfesten Einzelelementen (10), wie Fasern, Drähten und/oder Bändern. Wenigstens ein Teil der Einzelelemente (10) der Litze (18) ist durch eine Beschichtung (12) und/oder Füllmaterial in Form von Fasern (28) und/oder schüttfähigem Pulver beziehungsweise Granalien (30) in Abstand gehalten. Nach bevorzugten Varianten ist wenigstens ein Einzelelement (10) einer Litze (18) durch einen elektrisch gut leitenden Draht (46) oder einen optischen Leiter (44) ersetzt.
Abstract:
Provided are a rubber article reinforcing steel wire that is superior in bending fatigue properties to the related art and has a flat cross-sectional shape, and a rubber article using the wire. In a rubber article reinforcing steel wire 10, a major diameter and a minor diameter are substantially perpendicular to each other. Assuming that the major diameter is W, the minor diameter is T, a straight line that passes through a center of the major diameter in a width direction and is parallel to a minor diameter direction is L1, a straight line that passes through a center of the minor diameter in a width direction and is parallel to a major diameter direction is L2, an intersection point of the L1 and the L2 is a center point C, a region within a half of a distance from the center point C to a surface is a central region Rc, and a region outside the central region Rc is a surface layer region Rs, a Vickers hardness Hvc of the central region Rc is more than a Vickers hardness Hvs of the surface layer region Rs; and assuming that a Vickers hardness on the L1 in the surface layer region Rs is Hv1, and a Vickers hardness on the L2 in the surface layer region Rs is Hv2, relationships represented by Hvc−Hv1≦150, Hvc−Hv2≦150, Hv1/Hvc×100≧85.11, and Hv2/Hvc×100≧79.84 are satisfied.
Abstract:
A metal cord has cylindrical layers formed of an internal layer, an intermediate layer, and an external layer. The in internal layer includes M threads. The intermediate layer includes N threads wound in a helix around the internal layer. The external layer includes P threads wound in a helix around the intermediate layer. An inter-thread distance, D2, between the threads of the intermediate layer is greater than or equal to 25 μm. An inter-thread distance, D3, between the threads of the external layer is greater than or equal to 25 μm.
