Abstract
A laboratory-scale device for assisting in the simulation of heat setting conditions includes a pair of laterally spaced-apart flexible heat-resistant cords (e.g., formed of aramid fibers) tensioned between forward and rearward rigid cross-support bars. At least one rigid tensioning bar is provided parallel to the support cords and extending between the cross-support bars so as to maintain the desired tension on the flexible heat-resistant cords. The tensioning bar thus allows for manual or automated lateral winding of the synthetic heat-settable fibers or yarns about the spaced-apart heat-resistant cords during preparation of the device for a laboratory test run. The tensioning bar may thereafter be removed once the device has been secured in position with the laboratory heat-setting oven. In such a manner, therefore, various effects on heat-setting conditions simulating can be investigated.
