Abstract

La présente invention concerne une tige (2) comprenant : un matériau de base de tissu (20) ayant au moins une couche (20a) ; et une pluralité de matériaux linéaires (21) formés indépendamment l'un de l'autre et disposés côte à côte dans le matériau de base (20). Chacun de la pluralité de matériaux linéaires (21) comprend : une première partie (21a) qui est disposée sur au moins une extrémité du matériau linéaire (21) le long de la direction de la longueur et qui est fixée à la couche (20a) ; et une seconde partie (21b) qui est disposée sur une partie du matériau linéaire (21) autre que la première partie (21a) et qui n'est pas fixée à la couche (20a). Les secondes parties (21b) de matériaux linéaires adjacents (21) sont accrochées l'une sur l'autre. Une partie ou la totalité de la seconde partie (21b) d'au moins l'un des matériaux linéaires (21) est exposée à l'extérieur du matériau de base (20).
