Spinning lines AustRofil BCF Monocolour ‘Twin’ Polypropylene mulitfilament spinning technology for high output and flexibility BCF yarns are used mainly in carpets as pile yarn, for upholstery and furnishings. AUSTROFIL BCF monocolour twin extruder lines offers following advantages: • • • • • • • The flexibility derived from the simultaneous production of two differing yarn titer. The ease of operation provided by a separate texturising and cooling point for each yarn. A patented SML texturising unit for top crimp contraction and low shrinkage. Ingenious texturising design, which means that no lamellas are needed. Cooling of the texturised, compact plug for as long as 15 seconds. The avoidance of impurities through structural separation of the spinning, stretching, texturising and winding sections. Electronics protected and conditioned inside an e-container. The spinning line is equipped with 2 extruders and two electrically heated spinning beams. Short melt distribution avoids unnecessary long exposure of the melt to heat. The spinning pumps for each module can be started individually. Two quenching units, each with separate controls, are mounted. Below the air quenching, spin finish is applied to the filaments. The drawing and texturising units are stretching the yarn at a standard ratio of 1:2,5. Texturising occurs at speeds of up to 3,200 m/min, the yarns being opened in the crimper unit and then compressed by hot pressurised air into a plug with rectangular profile. This plug is subsequently wound around the cooling drum in multiple turns, drawn off and wound up. A wide titer range can be produced without changes to any of the components of the patented texturising unit, while the ingenious design of the crimper means that steel or ceramic lamellas are avoided. In addition, outstanding levels of cooling efficiency after texturising result in maximum bulk and minimum shrinkage. Two independent arranged extruders permit the simultaneous production of two yarns with different specifications, like titer and number of filaments. Between the two yarns it is possible to run separate granules, adjustments in extrusion, spinning, quenching, spin finish application, stretching, texturising and processing speeds. The size of the extruders and the modern control unit facilitate rapid colour and product changes. Moreover, the lines are ideally suited for the production of small lots. Two spinnerets per yarn ensure perfect cooling conditions which result in high output and excellent yarn quality. Simple operation and handling from the floor level is possible. The low overall height of the line facilitates installation in production halls with low ceiling heights. Austria - Europe
