Abstract
PURPOSE: To provide a pirn winding method, which is capable of improving efficiency of operation at the following stages by prescriling the condition of false twist applying process leaving a high residual torque of false twist and relationship between the direction of torque and pirn winding direction.
CONSTITUTION: In a method of winding filament yarn continuously around a pirn after applying false twist, slightly crimped yarn 1, for instance, false twisted to have a number of false twisting less than 15000/D1/2 and having a strong residual torque of false twist in clockwise direction, is wound around pirn 2 while applying twist in the conterclockwise direction as viewed from the bottom of pirn 2. Here, yarn is false twisted, for instance, by way of a twisting method in which yarn is run while binding the same to fixed pin more than once. Thus, yarn is wound around pirn 2 in the opposite direction as compared with conventional method, so that crimped yarn is crimped additionally in over-untwisting direction. Therefore, it is prevented that kinky thread is produced in drawing out the yarn from pirn 2 and yarn can be drawn out straight from the pirn.
