| Zusammenfassung: | A hybrid cord comprises (i) a first yarn, without initial S or Z twist, of continuous polymeric filaments forming the core of the cord, the yarn being a non-bulked yarn, (ii) a second yarn, without initial S or Z twist, of continuous polymeric filaments, the second yarn being a bulked yarn that is wrapped around the first yarn, wherein (a) the second yarn is wrapped around the first yarn at an angle of from 5 to 40 degrees, (b) the second yarn has a length that is from 4 to 35 percent longer than that of the first yarn, and (c) the hybrid cord is unbalanced and has an S or Z twist.
L'invention concerne un cordon hybride qui comprend : (i) un premier fil, sans torsion initiale en S ou Z, de filaments polymères continus formant l'âme du cordon, le fil étant un fil non texturé, (ii) un second fil, sans torsion initiale en S ou Z, de filaments polymères continus, le second fil étant un fil texturé qui est enroulé autour du premier fil, (a) le second fil étant enroulé autour du premier fil selon un angle de 5 à 40 degrés, (b) le second fil ayant une longueur qui est de 4 à 35 % plus longue que celle du premier fil, et (c) le cordon hybride étant déséquilibré et présentant une torsion en S ou Z. |
