    摘要: 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.

    摘要: A spin pack for spinning multiple components includes a distribution device which distributes mutually separated molten polymer streams to a spinneret so that each mutually separated molten polymer stream is accessible at each active spinneret backhole. Intermediate the spinneret and the distribution device, a selection assembly selects which, if any, mutually separated molten polymer stream flows into which backhole.

    摘要: The concentration of a colorant in a stream of molten polymer is measured by inserting a probe adjacent to the stream. The probe has integral therein collection means and illumination means. The steam is illuminated with the illumination means to cause electromagnetic radiation to be reflected from the molten polymer. The electromagnetic reflectance is collected, transmitted to a measurement device remote from the molten stream and quantified as a function of the concentration of the colorant.
