Abstract

L'invention concerne une structure de textile tissé sous forme de bande qui est formée à partir de fibres synthétiques ne se liant pas par fusion et de fibres synthétiques se liant par fusion incorporant dans la surface des fibres un ingrédient se liant par fusion dont le point d'amollissement est inférieur d'au moins 30° Celsius à celui des fibres synthétiques ne se liant pas par fusion. Selon l'invention, les fibres synthétiques se liant par fusion sont utilisées pour au moins une partie de la trame dans la structure de textile tissé et ont subi un traitement thermique à une température qui n'est pas inférieure au point d'amollissement de l'ingrédient se liant par fusion. De plus, les fibres synthétiques se liant par fusion ont été collées par fusion à elles-mêmes ou aux fibres synthétiques ne se liant pas par fusion. Selon la structure de textile tissé de l'invention, une structure de textile tissé sous forme de bande, par ex. une bande continue pour ceintures de sécurité, peut être produite efficacement, qui, même utilisée de manière répétée, conserve sa rigidité dans le sens de la trame pendant longtemps, est moins susceptible de se tordre et est douce et facile à manier.
