Claims
- 1. A process for continuously melt spinning and drawing nylon 6 to form a yarn comprising the steps of melt extruding said yarn, applying an aqueous emulsion finish to said yarn immediately after extrusion, thereby causing lengthening of and liveliness in said yarn, passing said yarn while in an undrawn state through at least two stages of a substantially unheated winding zone, increasing the rate of speed of the yarn at least between the first and second stages of passage within said winding zone an amount sufficient to compensate for said yarn lengthening and to thereby reduce the yarn liveliness resulting therefrom, and drawing said yarn away from the last stage of said winding zone.
- 2. In a process for continuously melt spinning a nylon 6 yarn, wrapping said yarn around a substantially unheated winding godet in multiple wraps sufficient to eliminate slippage, drawing said yarn, and applying an aqueous emulsion finish to said yarn after spinning but before drawing thereby causing lengthening of and liveliness in said yarn on said winding godet, the improvement which comprises increasing the speed of said yarn at least about 2% from the first to at least the second of said multiple yarn wraps an amount sufficient to compensate for said yarn lengthening and to thereby reduce the yarn liveliness resulting therefrom.
