Beschreibung
Zusammenfassung:	FIELD: dry-wet aminoxide forming equipment. SUBSTANCE: forming apparatus has spinneret with spinning openings for extruding single filaments; blow-off device for cooling extruded single filaments discharged from spinning openings; vessel with settling tank liquid; yarn forming member positioned in settling tank and adapted for connecting extruded filaments to obtain bundles; air gap defined by space between spinneret and surface of liquid in settling machine. Yarn forming member is spaced from spinneret so that maximum angle (alpha),, defined by single filaments and perpendicular to liquid surface in settling chamber, is 45 deg, with ratio of 0.1+0.005 1 0.7 d(o)(h-1)/h, where d(o) is distance (mm) between spinning opening and related adjacent spinning opening of spinneret; h is distance (mm) from yarn forming member to spinneret; 1 is air gap (mm), with 0.4 mm being d(o) 2 mm and 0
