1-Step Process

From Resin to Fiber in One Line

The compact one-stage process from Trützschler combines fiber spinning and fiber tow processing and thus, offers maximum flexibility. The main advantages of the one-stage process as compared to two-stage process are less equipment and reduced space requirement. This results in a reduction of investment costs which in turn allows economic production of smaller quantities. With fewer operators required, the operating costs are lower than with the two-stage solution.

The one-stage process comprises all components, from extrusion, fiber spinning to drawing, crimping and cutting. It is the perfect solution for frequent changes of master batches, alternate processing of different polymers, and use of recycled polymers such as PET bottle flakes.

Equipment for melt preparation is provided only by reliable suppliers. Trützschler Man-Made Fibers ensures that the best and most economical technology available on the market is offered for each individual application.

2-Step Process

Two Steps to High Quality Fibers

In Trützschler's conventional two-stage process with a spinning system and a separate fiber line, the fiber tow is deposited in cans prior to downstream processing. The high spinning speeds allow for an economic production of high quality fibers, especially of bicomponent fibers. The two-stage process is particularly suited for low denier, high-strength fibers with low shrinkage and high output.

The product line includes solutions for:

  • Thermoplastic polymers such as PET and R-PET, PP and PA
  • Bicomponents
  • Solution of spinning of polyacrylic (PAN) and aramid fibers

Trützschler Man-Made Fibers' two-stage fiber lines are both ideal for small installations with 12 spinning positions as well as for maximum capacities up to 300 t/day for cotton PET per production line.
