Beschreibung
Zusammenfassung:	A method for the manufacture of uncoated technical woven fabrics in a dense fabric construction with low air permeability, the woven fabric consisting of polyamide filament yarns having a hot air shrinkage of 6 - 15 % (measured at 160 DEG C) and having an at least essentially symmetrical fabric construction. To set the required air permeability, the woven fabric is subjected to treatment in an aqueous bath at 60 - 140 DEG C.
