The balancing is the key: Yarn Quality - Maintenance - Cot life time
Improved filament quality is a substantial competitive advantage for today’s texturing mills. To achieve best filament quality a high quality texturing cot is required; the performance of the texturing cot however depends largely on the proper preparation of the cot surface.
For a good performance the texturing cot needs the correct surface roughness.
We recommend a value of Ra 1.0 - 1.3 μm.
