Abstract

L'invention concerne un fil mélangé multifilament en polyester qui peut présenter une sensation de volume et de douceur similaire à celle des fibres naturelles. L'invention concerne également un tissu, un procédé de fabrication du fil mélangé multifilament en polyester, et un procédé de fabrication du tissu.　Dans un fil mélangé multifilament en polyester (1) obtenu par l'entrelacement d'au moins deux types de fils multifilaments en polyester ayant différents taux de retrait thermique, les deux types de fils multifilaments en polyester comprennent un fil à fausse torsion (10) et un fil partiellement étiré (20), et les deux fils sont soumis à un retrait thermique à sec. Bien qu'un rétrécissement important se produise globalement par retrait thermique, des emplacements avec différents niveaux de retrait sont présents et mélangés de manière localisée, et les deux fils sont exposés de manière irrégulière à l'extérieur. L'irrégularité du niveau de teinture due aux différences de niveau de retrait dans la direction longitudinale du fil mélangé, et l'irrégularité du niveau de teinture due à des différences des degrés d'orientation des deux fils sont combinées, et de ce fait, une sensation d'ondulation irrégulière est formée dans la direction longitudinale du fil mélangé après la teinture, et des tons et des textures de couleur tels que ceux de fibres naturelles sont présentés dans le tissu.
