embodiment 1

[0137] Melt-spinning process was performed on polyethylene terephthalate under the same conditions as Embodiment 1 other than those shown in Table 1, and the thread was wound on each godet roller and taken up by the winder without reciprocating the converging guide. The results of evaluation of stain on the roller, a single filament breakage, and thread breakage are shown in Table 1. Consequently, in the case where the thread was not traversed on the godet roller, the surface of the roller was maintained in lightly stained condition until the second day, but occurrence of a single filament breakage was suddenly increased on the third day, and thereafter, the thread could not taken up and occurrence of thread breakage was increased significantly.

embodiment 2

[0139] Melt-spinning process was performed on PET under the same conditions other than the conditions shown in Table 1. The results are shown in Table 1.

Abstract

In the process of drawing / heat treating synthetic fiber thread melted and spun via a plurality of godet rollers and subsequently winding the same, accumulation of extraneous matter on the surface of the godet rollers may be prevented by performing multistage drawing / heat treatment while reciprocating the thread in the direction of the axis of rotation of the godet roller using the godet rollers at least two of which have surfaces having the roughness of 0.5<=Ra<=5 and one of which has a surface at a temperature of at least (melting point of synthetic fiber-70° C.), whereby occurrence of thread breakage or generation of fuzz may be prevented and synthetic fiber whereof the rate of operation can be increased and efficiency of manufacture is improved may be obtained.

Description

[0001] 1. Field of the Invention[0002] In the manufacture of synthetic fiber, especially, of industrial fiber formed by drawing / heat treatment of undrawn thread by the use of a plurality of godet roller groups, the present invention relates to a method of manufacturing high-strength synthetic fiber for maintaining drawing / heat treatment of synthetic fiber stable for a long term by resolving problems such as thread breakage or generation of fuzz to avoid accumulation of extraneous matters on the surface of high-temperature godet rollers, for increasing the rate of operation by reducing the number of times the machine have to be stopped for removing extraneous matters from the godet rollers, and for improving productive efficiency by reducing abrasion of the surface of the godet roller, and a thread traversing device to be used directly in the same method.[0003] 2. Description of the Related Art[0004] In the manufacture of synthetic fiber as typified by polyamide or polyester, among o...
