Abstract

Présentation d'une toile filée fabriquée à base d'un mélange composé d'un polymère thermoplastique et d'un additif assouplissant dont le taux en poids s'élève à 3 %; la toile aura subi un traitement mécanique visant à en augmenter la souplesse. La valeur finale d'étirage et d'écrasement de la toile est inférieure de plus de 50 % à la valeur d'étirage et d'écrasement initiale; la chute de la valeur d'étirage et d'écrasement dépasse la somme des traitements individuels. La toile est composée d'une seule couche ou représente un stratifié de matériaux filés-liés ou autres tels que les étoffes obtenues par soufflage ou appartenant au type "coform".
