Abstract

Abstract Translated from German Verfahren zur Herstellung von unbeschichteten Technischen Geweben in dichter Gewebeeinstellung mit geringer Luftdurchlässigkeit, wobei das Gewebe aus Polyamid-Filamentgarnen mit einem Heißluftschrumpf von 6 - 15 % (gemessen bei 160 °C) besteht und eine wenigstens im wesentlichen symmetrische Gewebeeinstellung aufweist. Zur Einstellung der geforderten Luftdurchlässigkeit wird das Gewebe einer Behandlung in einem wäßrigen Bad bei 60 - 140 °C unterzogen. Process for the production of uncoated technical fabrics in dense fabric setting with low air permeability, the fabric consisting of polyamide filament yarns with a hot air shrinkage of 6-15% (measured at 160 ° C.) and having an at least substantially symmetrical fabric setting. In order to set the required air permeability, the fabric is subjected to a treatment in an aqueous bath at 60-140 ° C.
