Abstract: A device and a method for manufacturing a synthetic yarn, in which at least two yarn plugs (1), (2), (3) are produced by texturing, are placed in a first zone (A) on the cooling surface (6c) of a rotating cooling drum (6), moved to a second zone (B) and form more than one winding (I),(II), in which the yarn plugs are kept in the second zone (B) by a gas stream (FB) on the cooling surface (6c), and in which no gas stream or a less powerful gas stream is generated in an intermediate zone (C) in order to prevent the yarn plugs (1), (2), (3) from leaving the second zone (B).

Abstract: A method for producing a textile product (I), (II), comprising at least two synthetic pile threads (P1), (P2) having a different pile height, so that a predetermined design is formed, in which the synthetic pile yarns (P1), (P2) are manufactured by extrusion from the same raw material, according to production processes which only differ from each other by a different setting of one or several process parameters of their respective extrusion processes, so that they have a different shrinking capability, and in which the textile product (I), (II) is subjected to a heat treatment which causes the pile yarns (P1), (P2) to shrink differently. Also such a method for producing synthetic textile yarns (P1), (P2) having a different shrinking capability.
