Title
(EN) MIXED-FILAMENT POLYAMIDE COMPOSITE YARN FOR FALSE TWISTING
(FR) FIL COMPOSITE DE POLYAMIDE À FILAMENTS MÉLANGÉS POUR FAUSSE TORSION
(JA) 仮撚用ポリアミド混繊複合糸
Abstract
(EN)
Provided is a mixed-filament polyamide composite yarn for false twisting which is rendered suitable, by false twisting, for obtaining high-quality woven or knit fabric that has softness and is excellent in terms of water-absorbing and rapidly drying properties and mild glossiness. The mixed-filament polyamide composite yarn for false twisting is a mixed-filament polyamide composite yarn configured from dispersed and mixed filaments of at least two kinds differing in sectional shape. The composite yarn is characterized in that the cross-section, in the direction perpendicular to the machine direction, of the filaments of at least one kind has a shape having no recess, the cross-section, in the direction perpendicular to the machine direction, of the other filaments has a shape having one or more recesses, and the filaments of each kind have an average fineness of 1.3 dtex or less.

La présente invention concerne un fil composite de polyamide à filaments mélangés pour fausse torsion qui est rendu approprié, par fausse torsion, pour obtenir un tissu tissé ou maillé de haute qualité qui possède une douceur et d'excellentes propriétés d'absorption d'eau et de séchage rapide et une faible brillance. Le fil composite de polyamide à filaments mélangés pour fausse torsion est un fil composite de polyamide à filaments mélangés conçu à partir de filaments dispersés et mélangés ayant au moins deux types de forme de section différente. Le fil composite est caractérisé en ce que la section transversale, dans le sens perpendiculaire au sens machine, des filaments d'au moins un type, possède une forme qui ne comporte aucun évidement, la section transversale, dans le sens perpendiculaire au sens machine, des autres filaments, possède une forme qui comporte un ou plusieurs évidements, et les filaments de chaque type possèdent une finesse moyenne de 1,3 dtex ou moins.
