A polyester blended woven yarn composed of spontaneously extensible polyester multifilament yarn (A) and heat shrink polyester multifilament yarn (B), wherein the polyester multifilament yarn (A) is comprised of a core part and multiple fin parts radially protruding from the core part along the length of the core part and wherein the following requirements (a) to (c) are simultaneously satisfied: (a) 1/20 <= SB/SA <= 1/3, (b) 0.6 <= LB/DA <= 3.0, and (c) WB/DA <= 1/4 (in which SA represents the cross section area of the core part; DA when the cross section of the core part is a perfect circle represents the diameter thereof and when it is not a perfect circle represents the ball set outside diameter thereof; and SB, LB and WB represent the cross section area, maximum length and maximum width of the fin parts, respectively).
L'invention concerne un fil polyester tissé mixte composé d'un fil multifilament (A) polyester autoextensible et d'un fil multifilament (B) polyester thermorétrécissant. Le fil multifilament (A) polyester est composé d'une âme et de plusieurs parties ailettes en saillie radiale à partir de l'âme et disposées sur sa longueur, les exigences (a) à (c) suivantes étant simultanément satisfaites : (a) 1/20 = S<SB>B</SB>/S<SB>A</SB> = 1/3, (b) 0.6 = L<SB>B</SB>/D<SB>A</SB> = 3.0, (c) W<SB>B</SB>/D<SB>A</SB> = ?, sachant que S<SB>A</SB> représente la superficie en coupe de l'âme ; D<SB>A</SB>, lorsque la section transversale de l'âme est un cercle parfait, désigne son diamètre, et lorsqu'il n'est pas parfait, le diamètre externe de l'ensemble sphérique ; S<SB>B</SB>, L<SB>B</SB> et W<SB>B</SB> signifient respectivement la superficie en coupe, la longueur maximale et la largeur maximale des parties ailettes.
