Integrated Draw Frame IDF 2 for airjet spinning



Only one draw frame passage – the success formula for VORTEX

The two world market leaders – Truetzschler in the field of spinning preparation and ­Muratec in the field of airjet spinning machines – have developed a new, more economical preparation procedure together.

Optimum preparation for VORTEX by Truetzschler

For a high parallelisation in airjet spinning, three draw frame passages have been the only way to achieve good quality up to now. Today, the combination of the card with the Integrated Draw Frame IDF 2 allows a significant process reduction.
IDF 2 with short-wave levelling ensures a perfect feed for the downstream autoleveller draw frame. This process shortening by two complete process steps opens up an enormous savings potential.

Fewer steps – higher yarn production

A higher profitability in spinning means a higher yarn production per day. Yarn clearer cuts have a great influence on the efficiency of a spinning machine. In spinning tests with viscose for Ne 30, yarn clearer cuts could be significantly reduced with the new IDF VORTEX SPINNING.

Process approval:
  • 100 % viscose (rayon)
  • Yarn count: Ne 10 – Ne 40
Cutting can transports in half

Savings in can handling depend on the can ­diameter used between the cards and the draw frame passages. Even when using highly economical large cans with a 1,000 mm diameter, there is a significant reduction in can movements, the number of operators ­required and the number of cans required.

Improvement of quality

Fewer cans also means fewer sliver piecings. This is a very important quality aspect. Every sliver piecing is a potential yarn imperfection. A production of 21 tons of yarn results in a reduction of 900 sliver piecings per day.

Savings at a glance:

13 % less space requirement in spinning
4 % less energy consumption
9 % less exhaust air consumption
900 less sliver piecings per day

Total savings:

Operator: 50,000 $ p.a.
Building: 260,000 $
Installed power: 14,900 $ p.a.
Exhaust air: 5,250 $ p.a.

Basis: 850 kg/h · 0.13 $/kWh · 500 $/m2

Shorter preparation procedure for airjet: only 1 passage instead of the usual 3 passages in the drafting process
Significantly reduced can movements and sliver piecings
