Abstract

Cette invention concerne une armature raschel qui est obtenue en entrelaçant des fibres de polytriméthylène-terephtalate, pour former une armature de fond, à des fibres élastiques pour un tricotage rapporté. Cette invention concerne plus précisément un tissu tricoté à chaîne raschel extensible dans lequel le nombre de rangées varie de 100 à 200 / 2,54 cm, tandis que le produit du nombre de rangées / 2,54 cm par le nombre de colonnes / 2,54 cm varie de 4000 à 8000. Ce tissu n'est pas sujet au jaunissement, ne comporte pas de défauts notables, offre une sensation douce, et représente un matériau textile qui convient pour des vêtements élastiques possédant d'excellentes caractéristiques de thermoformage.
