Abstract: PURPOSE:To obtain a device for heat-treating yarn capable of surely threading yarn to a heat-treating chamber, having excellent heat efficiency and uniformity of heat treatment of yarn, capable of threading without end breakage even in the case of undrawn yarn. CONSTITUTION:This device for heat-treating yarn is characterized by having a yarn sucking means 6 at the top of treating chamber, and providing a yarn handing area guide 2 having a surface finishing state of >=0.4 (s) and

Abstract: PURPOSE: To make yarn surely passable in a short time even in the case where it is applied to the undrawing yarn by installing a yarn passage guide, whose surface finished state is specified, in the yarn filament inlet part of a filament suction means. CONSTITUTION: A range if 0.4 to 25S is required to the surface roughness of a part coming into contact with a yarn filament 10 of a yarn passage guide 2. First of all, this filament 10 discharged out of a spinning pack is predrawn by a suction gun 18 by way of a guide 19 installed upstream a filament suction means 6. Next, with a cock 8 opened, high pressure gas is induced out of a high pressure gas pipe 7, then high pressure gas is blown out as accelerating it through a slit 5, whereby negative pressure is produced in the vicinity of a filament inlet hole 1. When the filament 10 being drawn by the suction gun 18 is cut by scissors and the like hereat, the feed filament 10 is drawn from the filament inlet hole 1, it is passed through downstream. If this filament 10 is received by the suction gun at the downstream side of a heat treatment equipment 13, yarn passing is over. At this time, if the surface roughness is smaller than 0.4 S, a friction factor with the filament grows larger, but if it is larger than 25S, some hitch of the filament will partially occur there.

Abstract: PURPOSE:To allow fibers to stably travel on a godet roller by disposing a fiber-protecting member covering the all fibers in the proximity of the fibers approaching the godet roller. CONSTITUTION:A fiber-protecting member covering all fibers with at least its inner surface in the fiber-spreading direction X is disposed in the proximity of the fibers approaching a godet roller. The width of the fiber-protecting member is preferably longer >=10mm than the width X of the fibers at both its side ends, and the length of the fiber-protecting member in the direction along the fibers is preferably.>=50mm.
