A jet dyeing machine moves the fabric by

  • A.an overhead reel working on its own
  • B.winding it from one roll onto another
  • C.rotating a perforated drum
  • D.the momentum of the circulating liquor

Answer: D

The liquor does the transport, so mechanical stress on the fabric is low and the liquor ratio can be kept small. High temperature versions run above the boil under pressure for polyester. The venturi is the heart of the machine.
