Abstract
A stabilizing or secondary heater, for producing a crimped set yarn, comprises a tube having two substantially parallel bores extending therealong, one bore providing a yarn path for the yarn. Air is passed along the other bore, in a direction opposed to the direction of travel of the yarn, so as to be heated, and then through a communicating inlet and passages to impinge upon and be entrained by yarn, the air travelling along the yarn path bore to prevent entrainment of cold ambient air therealong and to ensure good heat transfer to the yarn.
