A radial aircraft tire (1), defined in three main directions, circumferential (X), axial (Y) and radial (Z), comprises a crown (2) surmounted by a tread (3), two sidewalls (4), two beads (5), each sidewall (4) connecting each bead (5) to the crown (2), a carcass reinforcement (7) that is anchored in each of the beads (5) at at least one bead wire (6) and extends in the sidewalls (4) as far as the crown (2), a crown reinforcement or belt (10) that extends in the crown (2) in the circumferential direction (X) and is situated radially between the carcass reinforcement (7) and the tread (3), said carcass reinforcement (7) having at least one ply referred to as carcass ply in the form of a rubber matrix reinforced with radially oriented reinforcing elements, referred to as radial textile reinforcers, the latter being constituted entirely or partially by textile plied yarns of nylon comprising N multifilament strands twisted together to form a helix, characterized in that: N is greater than 2; the count of each strand is greater than 180 tex; the tenacity of each strand is greater than 75 cN/tex; the elongation at break of each strand is greater than 14%; the tenacity of each plied yarn is greater than 60 cN/tex; the elongation at break of each plied yarn is greater than 18%; and the helix angle of each plied yarn is greater than 20.

Embodiments disclose a utility model which is related to an advance utility paracord where a first plurality of strands and a second plurality of strands are braided. The first plurality of strands is braided and are made of one or more non-metallic materials. The second plurality of strands has a braided PE fishing line, a tinder line, and a thread. A non-transparent sheath encapsulates the first plurality of strands and the second plurality of strands.

A high-strength fibre rope (1) comprising a rope core as well as a sheathing indicating optical wear, wherein the sheathing comprises a sheath layer (2) made up of textile subunits (3, 4) of a first hierarchy level. An outermost sheath layer (2) is provided, wherein textile subunits (3, 4) of said outermost sheath layer of the first hierarchy level differ from each other in terms of their textile structure, and/or an outermost sheath layer and a further sheath layer underneath said outermost sheath layer are provided, and wherein the textile subunits of the first hierarchy level of said outermost sheath layer differ in their textile structure from that of said further sheath layer. The textile subunits of a lowermost hierarchy level of the rope are neither dispersed in a resin matrix in the outermost sheath layer nor in the further sheath layer arranged underneath the outermost sheath layer.
