Yarn treatment - with insert holding soln chemicals in soln recirculation system

摘要

The insert is suitably perforated to allow fluid to pass through but to retain solids, so that when a press. pump and control valve is operated, part of the treatment fluid is passed through the insert to allow the soln. to be strengthened to compensate for the weakening eefect as yarn treatment progresses. Ensures the correct treatment soln. strength is maintained.
