    The air nozzle has a continuous yarn channel (3.1) into which terminate laterally an air feed bore (5) and a threading slot (4). The wall of the yarn channel (3.1) contains two cylindrical, for example circular-cylindrical wall sections, namely a baffle wall section (6.1) lying in opposition to the air feed bore (5) and a nozzle wall section (9.1) proximate to the air feed bore (5).

    Drawing A process of stretching a filament after it has been formed so as to reduce its diameter. The ratio of the final length to the initial length is called the draw ratio. Controlled stretching of the filament by a factor of 4 to 10 causes the molecular chains to become aligned (oriented) along the fiber axis and makes the filament stronger.
