Problems solved by technology

In the spinning and drawing device described in Patent Document 1, it is necessary to make the feeding speed of the second heating roll and the second separating roll the same, so the tension of the yarn cannot be changed during the heat setting process at the second heating roll.
Therefore, the physical properties of the wire can only be controlled by changing the temperature of the second heating roll or changing the wire feeding speed difference (drawing ratio) between the first heating roll and the second heating roll
Therefore, there is a problem that the degree of freedom in controlling the physical properties of the yarn is narrow

Embodiment Construction

[0027] Embodiments of the present invention will be described below. figure 1 It is a front view showing the structure 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 the spinning winder. The following will figure 1 and figure 2 Each direction shown in is described as the up-down direction, the left-right direction, and the front-rear direction. Spinning winding machine 1 such as figure 1 and figure 2 As shown, a spinning drawing device 2 and a yarn winding device 3 are provided. The spinning winding machine 1 stretches a plurality of yarns Y spun from the spinning machine 4 located 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. The yarn Y is, for example, a preheated polyester fiber that needs to be stretched. In addition, an oiling a...

Abstract

The invention provides a spinning and drawing device, which makes it possible to control the physical properties of the filaments by changing the tension of the filaments in the heat setting process. The spinning drawing device (2) includes first godet rolls (21a, 21b) for preheating and second godet rolls (22a, 22b) for heat setting. The wire feeding speeds (V3, V4) of the second godet rolls (22a, 22b) are respectively set faster than the wire feeding speeds (V1, V2) of the first godet rolls (21a, 21b). And, in order to perform relaxation heat treatment on the yarn (Y), the wire feeding speed (V4) of the second godet roll (22b) is set slower than the wire feeding speed (V3) of the second godet roll (22a), or In order to perform tension heat treatment on the yarn (Y), the wire feeding speed (V4) of the second godet roll (22b) is set to be faster than the wire feeding speed (V3) of the second godet roll (22a).

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] We know a spinning drawing device equipped with a plurality of rolls that draw and heat-set polyester yarn spun from a spinning machine, and a spinning drawing device that winds the yarn drawn by the spinning drawing device to form a package Spinning winding machines such as yarn winding devices. [0003] The spinning and drawing apparatus described in Patent Document 1 includes a first heating roll, a first separation roll paired with the first heating roll, a second heating roll, and a second separation roll pairing with the second heating roll. After being wound on the first heating roller and the first separating roller multiple times, the thread is wound on the second heating roller and the second separating roller multiple times. [0004] The upstream first heating roller is set to a temperature at which the ...
