Embodiment Construction

[0027] First, a spinning drawing device 100 according to an embodiment of the present invention will be described.

[0028] figure 1 It is a figure which shows the whole structure of the spinning drawing-up apparatus 100. In general, spinning drawing equipment is divided into equipment for producing fully drawn yarn (FDY) in which the yarn is completely drawn, and equipment for producing partially oriented yarn (POY) in which the yarn is partially drawn. The spinning take-up facility 100 of this embodiment is a facility for producing fully drawn yarn (FDY).

[0029] The spinning take-up device 100 spins out the single fiber F, makes the yarn Y formed by bundling the single fiber F into a desired characteristic, and winds the yarn Y to form a package P. The spinning take-up facility 100 is mainly composed of a spinning device 10 , a godet roll group 20A, and a winding device 30 .

[0030] The spinning device 10 spins a plurality of single fibers F. The synthetic fiber raw m...

Abstract

The invention provides a yarn traction device which can control the temperature of yarn in a stretching zone with high precision and produce yarn with high quality. The yarn traction device (100) comprises one or more than one heating rollers (21a, 21b, 21c) heating yarn (Y) to a stretching temperature (Th) and one or more than one tempering rollers (22a, 22b) heating the yarn (Y) to a tempering temperature (Tt). The yarn (Y) is stretched between the heating roller (21c) on the most downstream side in the feeding direction of the yarn (Y) and the tempering roller (22a) on the most upstream side. The yarn traction device also comprises a heat preservation box (23) used for receiving the heating rollers (21a, 21b, 21c) and the tempering rollers (22a, 22b). The heating roller (21c) on the most downstream side is covered by a shield cover (24).

Description

technical field [0001] The present invention relates to the technology of spinning drawing equipment. In more detail, it is related with the spinning take-up facility which can perform high-quality yarn production. Background technique [0002] Conventionally, we know that there are stretching heating rollers (hereinafter referred to as "heating rollers") that heat the yarn to the drawing temperature, and tempering heating rollers (hereinafter referred to as "conditioning rollers") that heat the yarn to the conditioning temperature. Spinning drawing equipment. Such a spinning drawing device draws the yarn between a heating roll arranged on the most downstream side in the yarn feeding direction and a tempering roll arranged on the most upstream side (for example, Patent Document 1). Among them, the section in which the yarn is stretched is defined as a "stretching section". [0003] However, in order to produce a high-quality yarn, the temperature of the yarn in the drawin...
