ABSTRACT:
Apparatus for the production of yarn having a potential crimp which is achieved by varying the viscosity gradient in the mass of polymer upstream of the spinneret. The apparatus includes means for feeding polymer under pressure, a block which is connected to the outlet of the feeding means and a spinning head, including a spinneret formed with at least one row of holes, the spinning head being mounted on the block. At least one passage is defined through the block, for the passage of polymer from the feeding means to the spinneret, this passage having a frusto-conical upstream portion which converges in a downstream direction towards the spinneret. Heating or cooling means are provided on the block for imparting to the polymer, as it passes through the passage, a temperature differential between the polymer at the center of the passage and the polymer at the walls of the passage.
Means are also provided for receiving and possibly drafting the yarn which has been extruded through the spinneret.
