The process comprises the steps of depositing the yarn onto a conveyor belt in the form of a cohesive flexible continuous hollow cylindrical winding of yarns, said cylindrical winding being supported on said conveyor belt at least along a generatrix of said cylinder, said cylindrical winding being transported through a hood-shaped steaming chamber while following a conveying pass successively ascending, horizontal and descending, the treatment fluid being maintained air-free and pure within said chamber owing to relative specific weight effect.
