Abstract: A braided structure that includes a core and a sheath is provided. The core includes a yarn formed at least in part from an aromatic polymer (e.g., an aromatic polyester/liquid crystalline polymer or an aramid polymer), and the sheath, which includes a plurality of ultra high molecular weight polyolefin yarns, is braided around the core. The sheath has an overall diameter ranging from about 60 micrometers to about 650 micrometers. Despite its small diameter, the braided structure can be creep resistant and abrasion resistant while at the same time exhibiting low elongation, a high load at break, and high stiffness. The braided structure can be used in medical applications such as sutures, load bearing orthopedic applications, artificial tendons/ligaments, fixation devices, actuation cables, components for tissue repair, etc.

Abstract: Provided is a double braid rope structure which is provided with an inner core and an outer cover. In the double braid rope structure (10), the inner core (3) includes high strength and high modulus fibers with a yarn tenacity of 20 cN/dtex or higher and a yarn elastic modulus of 400 cN/dtex or higher, and has a ratio of yarn length/rope length of 1.005 or more and 1.200 or less, the rope length being determined as a length of a cut section (V) cut to a certain length from the rope structure (10), and the yarn length being determined as an average value of lengths of yarns constituting the inner core of the cut section (V).

Abstract: In a method for producing a braid that extends in a longitudinal direction, multiple individual strands are interwoven with one another. For this purpose, first and second spools are moved relative to one another, the individual strands being wound onto the spools. The first spools having first individual strands are guided on a path that circulates about the longitudinal axis with the result that the first individual strands are arranged in a helical manner at least in sections about the longitudinal axis. The second spools having second individual strands are arranged with respect to the direction of rotation at fixed angular positions with the result that the second individual strands are incorporated into the braid in a manner in which they extend parallel to the longitudinal direction.
