Abstract

La présente invention se réfère à des articles tricotés tissés pour vêtements qui utilisent, au moins dans une partie de ceux-ci, des fibres de polyamide multifilament et qui, lorsqu'ils sont portés en tant que vêtements féminins, confèrent une sensation de confort en réduisant une sensation de gêne et présentent un aspect mat et une texture lisse sans être transparents ; et à des vêtements féminins utilisant ces articles tricotés tissés pour vêtements. Les articles tricotés tissés selon la présente invention sont formés au moins en partie à l'aide de fibres de polyamide multifilament comprenant du polyvinylpyrrolidone à raison de 3,0-7,0 % en masse et de l'oxyde de titane à raison de 1,0-5,0 % en masse par rapport au polyamide, y compris des fibres de filaments A comportant une section transversale arrondie, et des fibres de filaments B, dont la section transversale comprend au moins deux parties en retrait et présente une valeur de lobes (LB) de 5 à 50 %, le rapport des fibres de filaments A sur les fibres de filaments B étant compris dans la plage des rapports massiques de 30:70-70:30, et les fibres de polyamide multifilament présentant un rapport de sertissage de 15 % au maximum lorsqu'un traitement de fausse torsion est appliqué.
