    • PURPOSE: A method differential-shrinkage blended yarns is provided to manufacture differential-shrinkage blended yarns with excellent elasticity, heat insulation, intensity, shrinkability and high uniformity, to reduce the manufacturing cost, and to manufacture fabrics with excellent drapability, softness and bulkiness in texture, excellent shrinkage recovery and color fastness. CONSTITUTION: A method of manufacturing differential-shrinkage blended yarns comprises: the step of preparing two bobbins(10, 20) on which two different kinds of PET POY yarns are wound; the step of feeding a PET POY yarn supplied from the first bobbin to a first heater(30) with a guide roller(12); the step of heat-treating it at the temperature of 180-230°C in the first heater; the step of passing it through a guide roller(14) and stretching it in the stretching ratio of 1.1-1.5 in a stretching machine(40); the step of feeding the stretched PET POY yarn and the non-stretched PET POY from the second bobbin to a feed roller(50) and blending them; the step of interlacing the two PET POY yarns with an air interlacing device(60); and the step of winding the blended yarn on a winding roller(80) at 400-500m/min of the yarn speed after heat-treating in a second heater(70) and oil-processing. The stretched PET POY yarn is manufactured by passing the yarn through the first roller and the second roller separately when stretching the PET POY yarn fed from the first bobbin; heat-treating in the first heater of 180-230°C and cooling by passing through the cooling plate; twisting with a twist spindle consisting of more than two pairs of friction discs in the yarn speed ratio of 1.5-1.7; and stretching in the stretching ratio of 1.1-1.5 by the speed difference among the first roller, the second roller and the third roller. The used guide is a guide that is able to control the distance between the two kinds of PET POY yarns and the first heater by changing the supply angle of the two kinds of PET POY yarns.
    • 目的:提供一种差动收缩混纺纱线,以制造具有优异弹性,隔热性,强度,收缩性和高均匀性的差分收缩混纺纱线,以降低制造成本,并且制造具有优异的悬垂性,柔软性和蓬松性的织物 质地好,收缩恢复性好,色牢度好。 构成:制造差动收缩混纺纱线的方法包括:制备两根不同种类的PET POY纱线缠绕的两个线轴(10,20)的步骤; 将由第一筒管供给的PET POY纱线与引导辊(12)进行供给到第一加热器(30)的步骤; 在第一加热器中在180-230℃的温度下对其进行热处理的步骤; 在拉伸机(40)中使其穿过导辊(14)并以1.1-1.5的拉伸比拉伸的步骤; 将拉伸的PET POY纱线和未拉伸PET POY从第二筒管供给到进给辊(50)并混合的步骤; 将两根PET POY纱线与空气交织装置(60)交织的步骤; 以及在第二加热器(70)中进行热处理之后以400-500m / min的速度将混合纱线卷绕在卷绕辊(80)上的步骤,并进行油加工。 拉伸PET POY纱线是在拉伸从第一纱管供给的PET POY纱线时使纱线分别通过第一辊和第二辊而制成的; 在180-230℃的第一加热器中进行热处理,并通过冷却板进行冷却; 在纺纱速度比为1.5-1.7的情况下用由两对以上摩擦片组成的捻纱机进行扭转; 并且通过第一辊,第二辊和第三辊之间的速度差以1.1-1.5的拉伸比拉伸。 所使用的导向件是能够通过改变两种PET POY纱线的供给角度来控制两种PET POY纱线和第一加热器之间的距离的引导件。
