Abstract

La présente invention concerne un fil extensible contenant des fibres de verre présentant une excellente résistance au découpage et une grande élasticité, et qui est par conséquent adapté à la fabrication de tissus extrêmement flexibles, et concerne également des vêtements et d'autres produits textiles fabriqués au moyen d'un tel fil extensible. L'invention concerne également un fil extensible dans lequel une couche de recouvrement présentant une résistance au découpage est formée autour d'un fil d'âme élastique par un fil de recouvrement, ledit fil de recouvrement, obtenu par enroulement de fibres de faible allongement autour d'un fil d'âme utilisant des fibres élastiques et d'un fil d'âme utilisant des fibres de verre pour les fibres élastiques, est enroulé dans la même direction que la direction dans laquelle les fibres de faible allongement sont enroulées par rapport au fil en fibre de verre. Des fibres de polyuréthane produisent un fil d'âme élastique idéal. Il est souhaitable qu'un fil à fibre de faible allongement soit moins extensible qu'un fil en fibre de verre, qu'il présente un faible allongement et une résistance élevée, par exemple un fil à fibre en polyéthylène haute densité.
