Abstract
Strand material, such as yarns, tow or film, is processed through a fluid treatment apparatus which utilizes a polylaminar stack structure to form an elongate strand processing duct which has a strand inlet, a strand outlet, and a duct cross section which changes both in breadth and in height between the inlet and outlet.
