Abstract
Apparatus for spinning viscose rayon comprising an acid bath having an enclosure arranged for substantially completely trapping and collecting any gases emanating from said bath, a plurality of fiber-forming jets disposed substantially along beneath the surface of said acid bath, means for forcing aqueous xanthated alkali cellulose in liquid form into said jets and through said jets upwardly into said bath, and take-up means located within said enclosure above said bath for taking up the resulting fibers in an upward direction within said enclosure, and thence through an enclosed secondary hot bath for the purpose of stretching the cellulose-xanthate, regenerating it to cellulose, and for trapping and collecting gases and other chemicals.
