Embodiment Construction

[0039] Embodiments of the present invention will be described below. figure 1 It is a front view of a spinning winder equipped with a spinning drawing device according to an embodiment of the present invention, figure 2 It is a side view of a spinning winder equipped with a spinning drawing device according to an embodiment of the present invention, image 3 It is the control block diagram of the spinning and drawing device.

[0040] Such as figure 1 , 2 As shown, the spinning winder 1 includes a spinning drawing device 2 and a yarn winding device 3 . The spinning winder 1 stretches a plurality of yarns Y spun from the spinning machine 4 above and supplied continuously by the spinning drawing device 2, sends them to the yarn winding device 3, and winds them up by the yarn winding device 3. A plurality of silk threads Y are wound. The yarn Y is, for example, preheated PET that needs to be stretched. In addition, the plurality of yarns Y spun from the spinning machine 4 a...

Abstract

An object of the present invention is to enable a wider range of control of physical properties of yarns. When relaxation heat treatment is performed, yarn feeding speeds of second godet rollers 22a, 22b, and 22c are controlled so that between every two second godet rollers which are adjacent to each other in a yarn running direction, the yarn feeding speed of the second godet roller located downstream in the yarn running direction is lower than the second godet roller located upstream in the yarn running direction, and temperatures of the second godet rollers 22a, 22b, and 22c are controlled so that the temperature of the heating roller 22c located most downstream in the yarn running direction is higher than or equal to the temperature of each of the remaining heating rollers 22a and 22b. When heat treatment under tension is performed, the yarn feeding speeds of the second godet rollers 22a, 22b, and 22c are controlled so that between every two second godet rollers which are adjacent to each other in the yarn running direction, the yarn feeding speed of the second godet roller located downstream in the yarn running direction is higher than the second godet roller located upstream in the yarn running direction, and the temperatures of the second godet rollers 22a, 22b, and 22c are controlled so that the temperature of the heating roller 22a located most upstream in the yarn running direction is higher than or equal to the temperature of each of the remaining heating rollers 22b and 22c.

Description

technical field [0001] The present invention relates to a spinning drawing device for drawing a yarn spun from a spinning machine. Background technique [0002] For example, Patent Document 1 discloses a spinning and drawing device for drawing yarns such as polyethylene terephthalate (PET: Polyethylene Terephthalate) spun from a spinning machine. The spinning and drawing device is provided with at least one first roll and a plurality of second rolls which are heated rolls arranged downstream of the first roll in the yarn running direction and whose wire feeding speed is faster than the first roll. Then, the thread spun from the spinning machine is stretched between the first roll and the second roll, and at the same time, the stretched thread is heat-set by the plurality of second rolls. At this time, the physical properties of the thread are controlled by stretching conditions and conditions during heat setting. [0003] Specifically, the boiling water shrinkage (BWS: Boi...
