A Discussion of Generation of Interlaced Yarn by Model Experiment

Abstract

Interlaced yarn alternately has tangling parts and opening ones. It is produced by hitting steadily air with a fixed high-pressure on the multi-filament yarn, which runs at a fixed speed, using the air injection equipment called an interlacer. In order to clarify a mechanism of this production, we used a yarn constructed of small number of filaments with large fineness, carried out a model experiment that the resting yarn was hit at a second by high-pressure air, and tried the generation of interlaced yarn. As a result, a single-blowing experiment showed that an opening part and two tangling parts were generable at a certain probability on some conditions. Furthermore, we carried out a two-blowing experiment that the second air jet is hit on another yarn position apart from the yarn position on which the first air jet was hit. It showed that an interlaced yarn with new opening part and tangling one was generable at a certain probability.
