MEASUREMENT & ANALYSIS
See the yarn in detail
Evaluate yarn geometry and surface characteristics along the tested length. Compare results and investigate recurring variation in one PC-based workflow.
- Optical diameter & evenness
- Diameter variation evaluated with U%, CV% and SD from the optical diameter signal.
- Hairiness & filament anomalies
- Surface quality assessment through protruding fibre and filament irregularity analysis.
- Spectrogram & periodic analysis
- Graphical evaluation of recurring yarn variation along the tested length.
