Abstract

Dans des exemples, l'invention concerne un article vestimentaire comprenant un tissu modifié. L'article vestimentaire comprend une partie tissée monocouche et une partie tissée à double couche jointe sans coutures à la partie tissée monocouche pour former une poche. La poche comprend des bords latéraux fermés joints sans coutures à la partie tissée monocouche et une ouverture. La partie tissée monocouche est modifiée avec une première zone de module d'étirement présentant un premier niveau d'extensibilité et une seconde zone de module d'étirement présentant un second niveau d'extensibilité, de telle sorte que le premier niveau d'extensibilité est supérieur au second niveau d'extensibilité. La seconde zone de module d'étirement est située autour des bords fermés de la poche pour renforcer le contour de la poche.
