Abstract

L'invention concerne un tissu présentant un coefficient de frottement dynamique. Un coefficient de frottement de glissement de surface du tissu peut changer lorsque le tissu est étiré, et le coefficient de frottement de glissement de celui-ci par rapport au sens de la longueur et/ou au sens de la largeur change également en conséquence. Le tissu comprend au moins deux types de fil et est formé par tissage d'un fil possédant des propriétés de frottement de surface et/ou des fonctions de service différentes selon une certaine règle. Le fil comprend les éléments suivants selon la fonction : un fil à coefficient de frottement élevé (1), tel que de l'élasthanne, une fibre mer-île, un fil de gel de silice, etc.; un fil très pelucheux (2), tel qu'un fil texturé étiré (DTY), un fil texturé à l'air (ATY), etc.; et/ou un fil fonctionnel général (3), tel qu'un fil possédant des fonctions élastiques, d'isolation thermique, de protection contre les ultraviolets, d'élimination d'odeurs et d'autres fonctions. En plus de différents coefficients de frottement compris dans différentes conditions de degré d'ouverture et de glissement relatif, le tissu obtenu peut également être combiné avec des fonctions supplémentaires, telles que des fonctions de protection contre les ultraviolets, d'isolation thermique et d'élimination d'odeurs.
