PURPOSE:To obtain the title yarn suitable as a material for formal wear, having new luster effects, color tone with depth, etc., consisting of two kinds of polyester-based multifilament yarns having different elongations wherein at least one yarn has specific structure. CONSTITUTION:The objective yarn which comprises two kinds of polyester-based multifilament yarns having different elongations, is falsely twisted textured yarn partially having core part and outer peripheral part in the longer direction, wherein at least one of the two kinds of multifilament yarns contains 0.1wt.% dulling agent and 0.5-5wt.% kaolinite, can develop very fine holes which are formed long in the longer direction by alkali weight-loss treatment and satisfies <=0.7mum maximum of frequency distribution of maximum width, <=3 maximum of length/maximum width, >= average 30 holes based on 100mum<2> yarn surface and >=60% whole holes having <=0.1mum depth of hole on the surface of the yarn in the direction of fiber axis and has a crossectional shape of the filament of hollow crosssectional shape and/or flat crosssectional shape. |
