Method for cooling and finishing melt-spun filaments

摘要

A hollow quench stick tube capable of cooling and finishing melt-spun filaments comprises in one embodiment a hollow cooling tube connected to a hollow support tube, a finish applicator that substantially surrounds the hollow support tube, and a spoiler skirt that substantially surrounds the hollow cooling tube and that is spaced apart from the finish applicator to define a spoiler void. In operation, the spoiler skirt diverts a flow of air to create a partial vacuum in the spoiler void that draws a filament stream inwardly against the finish applicator.
