Spinning lines austrofil HT/MT version Polypropylene multifilament spinning technology for FDY and MDY yarns The name AUSTROFIL has become a synonym for top quality, high- and medium-tenacity, polypropylene yarn production machines. Indeed, today SML spinning lines for technical yarns are well known and employed extensively around the globe. HT/MT yarns are used for a range of both technical and textile applications. The advantages of AUSTROFIL HT/MT lines: • Low overall height allows installation in production halls with low ceiling height. • Simple operation and handling from floor level due to optimum ergonomic design. • Short melt distribution for high melt quality and quick colour changes. Following extrusion, the melt is pressed through an SML screen belt filter (optional), which removes producer to start with two stretching modules and impurities and secures consistent melt quality. Spinning then subsequently add two more, thus obtaining pumps in the electrically heated spinning beam furnish full production capacity in line with market needs the melt stream with steady and sufficient pressure. with a total of four stretching sections (HT/MT 4x2/4). Upon emerging from the spinnerets, the filaments are • Maximum of four yarns per drawing module ensures cooled in a controlled air stream. Subsequently, the high quality treatment. filaments are supplied with spin finish and drawn off to • Minimum waste in the case of yarn breaks, as only the stretching modules via godets. one stretching module is stopped. The yarn is cut and catched by a suction device. Three pairs of stretching rollers facilitate stretching ratios For this reason no new string up through the whole of up to 1:8, while the positioning of the hot air chamber machine is necessary. in the second stretching section ensures the highest • A special hot air chamber (HT version) designed yarn tenacity. Finally, the yarn is intermingled and wound for the highest tenacity. onto bobbins. • Flexible production of differing yarn qualities SML’s pre-shipment line testing prior to delivery assures based on a microprocessors control system, that customers receive fully functional systems, which which facilitates the input and alteration of process parameters. operate to their utmost satisfaction from day one. • Compact, modular design that allows the yarn Austria - Europe
