Abstract

Gegenstand der Erfindung ist ein Verfahren zur Verspin­ nung von segmentierten Polyurethanharnstoff-Elastomeren in Trockenspinnschächten unter Einleiten bestimmter Men­ gen an überhitztem Wasserdampf. Das Verfahren erlaubt eine außerordentliche Steigerung der Spinnleistung pro Schacht sowie Erhöhung der Spinngeschwindigkeit, insbe­ sondere bei Mittel- und Grobtitern, bei hohen Spinn­ schachttemperaturen und ohne unerwünschte Veränderung, zum Teil sogar unter deutlicher Verbesserung von Faden­ eigenschaften der erhaltenen Filamentgarne. Das neue Verfahren verhindert insbesondere auch Zersetzungsnei­ gungen der Spinnlösungsmittel bei (sonst für eine weit­ gehende Spinnlösungsmittelentfernung bei hohen Spinnge­ schwindigkeiten notwendigen) hohen Temperaturen in Luft, ohne daß inerte Gase als Spinnluftmedien eingesetzt werden müssen. Das neue Verfahren ermöglicht weiterhin das Erspinnen von (Multi)Filament-Garnen mit höheren Einzelfilamenttitern, was zur Verbesserung der Stabi­ lität der Filamentgarne gegen äußere Einwirkungen und Abbaueinflüsse beiträgt. The invention relates to a method for spinning segmented polyurethane urea elastomers in dry spinning shafts by introducing certain men overheated steam. The procedure allows an extraordinary increase in spinning performance per Shaft and increase in spinning speed, esp especially with medium and coarse titers, with high spinning shaft temperatures and without unwanted changes, sometimes even with a significant improvement in thread properties of the filament yarns obtained. The new In particular, the process also prevents decomposition additions of the spinning solvents (otherwise for a far walking spinning solvent removal at high spinning high temperatures in air, without using inert gases as spinning air media Need to become. The new process still enables the spinning of (multi) filament yarns with higher Single filament titers, what to improve the stabilization the filament yarns against external influences and Degradation influences.
