Abstract

Les fibres acryliques possèdent d'excellentes propriétés de rétention de chaleur, et sont donc utilisées fréquemment dans des vêtements tels que des pulls et des sous-vêtements. Concrètement, lorsque des fibres acryliques rétractables sont mélangées pour accroître les espaces vides entre les fibres, bien que des propriétés de légèreté/un encombrement puissent être obtenus, il existe toujours l'inconvénient de voir se produire un boulochage. À cet égard, il existe plusieurs propositions, mais aucune ne permet d'obtenir un niveau satisfaisant de propriétés de légèreté/d'encombrement et une résistance au boulochage efficace sur le plan pratique. La présente invention concerne un filé acrylique et un tissu qui possèdent chacun à la fois des propriétés de légèreté/un encombrement et une résistance au boulochage. L'invention porte en particulier : sur un filé comprenant des fibres à base d'acrylonitrile A et des fibres à base d'acrylonitrile B, ledit filé étant caractérisé en ce que les fibres à base d'acrylonitrile A possèdent une finesse de fibre unique de 0,3 à 1,7 dtex après traitement à l'eau bouillante et un allongement de fibre unique de 50 % ou plus, et en ce que les fibres à base d'acrylonitrile B possèdent une finesse de fibre unique de 0,3 à 2,2 dtex après traitement à l'eau bouillante et un allongement de fibre unique de 30 % ou moins ; et sur un tissu contenant le filé.
