Abstract
A weft fabric (T) for tires (10) comprises several textile warp reinforcing elements (44) and several weft reinforcing elements (50), wherein the moisture regain MR of the weft reinforcing elements (50) is less than or equal to 2.0%, the moisture regain being determined according to standard ASTM D 885/D 885MA of January 2010 the weft reinforcing elements (50) interweave the warp reinforcing elements (44), and the weft reinforcing elements (50) are hairy.
Claims15
A weft fabric for tires comprising several textile warp reinforcing elements and several weft reinforcing elements,
- wherein a moisture regain MR of the weft reinforcing elements is less than or equal to 2.0%, the moisture regain MR being determined according to standard ASTM D 885/D 885MA of January 2010,
- wherein the weft reinforcing elements interweave the warp reinforcing elements, and
- wherein the weft reinforcing elements are hairy.
A process for manufacturing a weft fabric comprising the steps of:
- in an unwinding step, unwinding several warp reinforcing elements from a creel on an air-jet loom;
- in a separation step, separating the warp reinforcing elements into a first and a second ply of warp reinforcing elements;
- in an interweaving step, alternately interweaving at least one weft reinforcing element with warp reinforcing elements of the first ply of warp reinforcing elements, then of the second ply of warp reinforcing elements;
- and
- in a winding step, winding the weft fabric on a storage reel,
- wherein a moisture regain MR of the weft reinforcing elements is less than or equal to 2.0%,
- wherein the moisture regain MR is determined according to standard ASTM D 885/D 885MA of January 2010, and
- wherein the weft reinforcing elements are hairy.
