Abstract
A new metal fiber yarn is provided. The metal fiber yarn (10) constitutes a construction comprising continuous metal fibers (13) forming a metal fiber yarn. The construction comprises at least 5 bundles (12) of continuous metal fibers twisted together to form a yarn. Each of the metal fiber bundles (12) comprises at least 30 metal fibers (13). The yarn comprises at least one partial yarn (11), said partial yarn comprising at least two metal fiber bundles (13) twisted around each other with a predetermined number of torsions per meter.
Claims15
A metal fiber yarn (10) comprising at least 5 bundles (12) of continuous metal fibers (13), said bundles (12) being twisted together, each of said metal fiber bundles (12) comprising at least 30 continuous metal fibers (13), characterised in that said yarn (10) comprises at least one partial yarn (11) wherein said partial yarn (11) comprises at least two of said continuous metal fiber bundles (12) twisted around each other with a predetermined number of torsions per meter.
Method of producing a continuous metal fiber yarn (10), said method comprising the following steps:
- providing at least 5 bundles (12) of continuous metal fibers, each of said bundles of continuous metal fibers comprising at least 30 metal fibers;
- twisting at least 2 of said at least 5 bundles of continuous metal fibers together with a predetermined number of torsions per meter to form at least one partial yarn (11);
- twisting said at least one partial yarn (11) together with the remaining continuous metal fiber bundles and/or partial yarns with a predetermined number of torsions per meter.
Method of producing a continuous metal fiber yarn (10), said method comprising the following steps:
- providing at least 5 composite wires, each of said composite wires comprising at least 30 metal fibers;
- twisting at least 2 of said at least 5 composite wires together with a predetermined number of torsions per meter to form at least one partial yarn;
- twisting said at least one partial yarn together with the remaining composite wires and/or partial yarns with a predetermined number of torsions per meter, thereby obtaining a composite wire construction;
- leaching said composite wire construction in appropriate acid, thereby obtaining the metal fiber yarn (10).
