    • A manufacturing method is disclosed for polyester blended yarns composed of filaments with different shrinkage percentage. The yarn also is good in bulkiness by maximizing the difference of the shrinkage percentage. The partially drawn yarn of polyester with inherent viscosity of 0.6-0.64 is heat set between the 2nd and 3rd rollers (2,3) of the multistage drawing machine for 0.01-0.5 seconds at 100-200deg.C; the partially drawn yarn of polyester and the high shrinkage polyester yarn are collected in the 3rd roller (3); and the 2 kinds of yarns are wound through the 4th roller (5) to get polyester blended yarns composed of filaments with different shrinkage percentage.
    • 公开了由具有不同收缩率的长丝组成的聚酯混纺纱线的制造方法。 通过最大化收缩率的差异,纱线也具有良好的蓬松性。 特种粘度为0.6-0.64的聚酯的部分拉伸纱线在100-200℃下在多级拉丝机的第二和第三辊(2,3)之间热定形0.01-0.5秒; 将聚酯的部分拉伸纱线和高收缩率聚酯纱线收集在第三辊子(3)中; 并通过第四辊(5)缠绕2根纱线,得到由不同收缩率的长丝组成的聚酯混纺纱线。
