SML has introduced a new multifilament spinning line concept, the Austrofil Vertex, optimised for PET yarn production in partially oriented yarn (POY) and fully drawn yarn (FDY) formats. The concept targets low titres in higher volumes, combining an optimised yarn path with a straightforward start-up and ramp-up routine. According to SML, Vertex is capable of manufacturing a wide range of yarn types, qualities and colours and, besides PET, can process PP and PA at comparable quality levels. Typical end products include fine yarns for textile applications, outdoor clothing, home textiles, carpet piles and upholstery. The line architecture is designed for expandability and customisation, with options that cover extruder configuration, spinning positions, the number of ends and the choice of winding units. Two separate spinning heads allow the parallel manufacture of two different products, supporting flexible production planning. “The Vertex series is the perfect addition to our top-selling Austrofil MT/HT multifilament spinning lines,” Thomas Pucher, Product Manager at SML, states.
Output and titre range
A key focus of the Vertex series is the titre range between 50 and 1,200 den at a maximum output capacity of up to 270 kg/h. SML reports that high-speed operation is compatible with low titres while maintaining quality. “Even at high speeds the Vertex concept guarantees premium quality at low titres. Generally, this is enabled by the precise interaction of key components, with the sophisticated yarn path making a particular contribution,” Thomas Pucher explains. The start-up process with a ramp-up function is intended to support efficient line operation.
Configuration and extendability
The Vertex concept is presented as highly configurable. Two separate spinning heads enable simultaneous production of different yarns, and spinning positions can be adjusted as required. The line can be equipped with one or two extruders of different types and performance parameters to match individual process needs. Thanks to a modular design, capacity expansion is possible by scaling the number of ends from 24 to 32, 48 or 64, depending on demand.
Winding options
Three winder variants are available, allowing manufacturers to prioritise either high-speed winding, high flexibility or a simplified winder design, depending on plant strategy and product mix.
