Abstract
A textile treatment apparatus for an endless textile hank is comprised of a vessel having a dwell or treatment zone at a lower portion thereof and an upper acceleration or feed zone above said dwell zone. A blower assembly mounted in the roof the vessel above the acceleration zone advances the hank by subjecting said to a purely gaseous stream so as to remove the hank from the exit of the dwell zone and introduce it into the entrance of such zone. Treatment nozzles located at the entry to the dwell zone saturate the hank and aid in guiding it unimpeded into the dwell zone. The location of the blower assembly or assemblies at the upper extremity of the vessel facilitate servicing and minimize fluid introduction into the gaseous feed stream.
