Embodiment Construction

[0030]Embodiments of the present invention will be described below with reference to the drawings. This embodiment is an example of applying the present invention to a spinning take-up device that draws a plurality of yarns made of polyethylene terephthalate (PET) spun from a spinning device.

[0031] Such as figure 1 As shown, a plurality of yarns 10 spun from the spinning device 2 are conveyed to the spinning drawing device 1 arranged below it. The plurality of threads 10 is composed of polyethylene terephthalate. The spinning drawing device 1 has a drawing unit 40 for drawing the plurality of yarns 10 delivered from the spinning device 2 , and a winding unit 50 for winding the plurality of yarns 10 delivered from the drawing unit 40 . Additionally, the following will figure 1 The left side of is defined as "left", and the figure 1 The right side of is defined as "right", and the figure 1 The close side of the paper is defined as "front", and the figure 1 The depth sid...

Abstract

The invention provides a spin stretching device. The device heats and stretches a spin formed by PET. The device comprises first heating rollers (4a, 4b, 4c) and second heating rollers (4d, 4e) with higher temperature than the first heating rollers. The spin feeding speeds of the first heating rollers (4a, 4b, 4c) are set to be faster and faster along the walking direction of spins (10) when the spins (10) are conveyed by the first heating rollers (4a, 4b, 4c) and stretched with a tension force range less than necking deformation tension. The spin feeding speed of the second heating roller (4d) is set to be faster than that of the first heating roller (4c) when the spin (10) is stretched between the first heating roller (4c) and the second heating roller (4d) by necking deformation tension.

Description

technical field [0001] The present invention relates to a spinning and drawing device and a spinning and drawing method for drawing a yarn spun from a spinning device. Background technique [0002] Patent Document 1 describes a spinning and pulling device for producing yarns made of polyester fibers such as polyethylene terephthalate (hereinafter abbreviated as PET) used for clothing and the like. This spinning take-up device includes three preheating rolls, two heating rolls, two guide rolls, a winding unit, and the like. The yarn spun continuously from the spinning device is heated, stretched, and heat-set by three preheating rolls and two heating rolls housed in an incubator. In addition, the following describes the case of producing a yarn made of PET. [0003] The yarn spun from the spinning device and sent to the incubator is wound on three preheating rollers (for example, 80-100°C) and preheated to a temperature slightly higher than the glass transition temperature ...
