Austrofil® FDY and MDY multifilament spinning line

Compact and flexible lines from the market leader.

SML’s accumulated expertise and decades of experience in multifilament spinning line engineering have made us market leaders in this field. No matter which yarn you are seeking to use – whether it is fully-drawn (FDY) or medium-drawn (MDY) – we can always supply the ideal lines for efficient production on your shop floor.

High performance across the board.

When it comes to belts, safety netting, ropes (including rigging ropes) or sewing thread for various types of bags, our high-tenacity fully-drawn yarn is the ideal solution for the technical textile industry. Whereas medium-drawn yarns are often used in home textiles and for bag material. 

Equipment that is fully geared to the market.

With four different machine designs, Austrofil® can cover all the market’s needs. Long working lives, short unit heights and reliable parts have all helped to make us one of the market leaders in multifilament spinning lines for technical and textile yarns. All Austrofil® machines are equipped with high-speed winders, which reliably guarantee automatic bobbin changes.

The HT series also have a hot air oven in which the yarn is gently and evenly heat-treated, allowing them to be stretched as far as possible. This enables customers to produce yarns in the highest tenacity range.

The compact multifilament spinning line is particularly well-suited to small batch sizes, packing a persuasive punch with its high degree of flexibility and efficiency. The line’s maximum output rate is 110 kg/h on its winder and the system is equipped with two stretching units. In addition, it offers outstanding filament cooling thanks to the use of two spinnerets for each yarn.
