CA 2249327
There is provided a web which has been spun from a mixture of thermoplastic polymer and a softening additive in an amount up to about 3 weight percent, and which has been mechanically treated to increase softness. The web has a final cup crush value which is less than 50 percent of the starting cup crush value and the drop in cup crush value is greater than the sum of the treatments individually. The web may be a single layer or may be a laminate of spunbond and other materials such as meltblown and coform fabrics.
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".
