5. Best working place conditions

In Detail

After spinning machine the viscose tow enters into one or more Lenzing Technik stretching units to get highest possible fiber tenacity.

The stretching unit itself consists mainly of frame, a number of stretch rollers made of special kind of stainless steel, single drive each roller and automatically operated window.

Due to frequency converter control of each single driven stretch roller different stretch ratios and therefore different fiber qualities (tenacity) can be adjusted.

The automatic operated window capsulate the stretch unit and enables an easy gas collection for gas recovery on the one hand and an improved working place condition on the other hand as CS₂ and H₂S containing gases can not escape out of the machine.
