Acoustic Measurement
Acoustic resonance frequency analysis yields high-precision linear density measurements for single textile fibers under controlled mechanical tension. Laboratory technicians perform the dtex micro vibrational test to verify fineness distributions across raw flax samples without destructive weighing. Fundamental natural frequency correlates directly with mass per unit length under constant gauge length and axial tension.
Precision instruments record acoustic feedback to compute decitex values instantly.
Resonance Frequency
The measurement apparatus secures an individual flax fiber between two clamping jaws and applies a precise mechanical tension force. Acoustic transducers induce transverse vibrations across the fiber span while optical sensors detect maximum resonance amplitude. Executing a dtex micro vibrational test on single flax elements exposes microscopic variation caused by cell wall thickness differences along the stem length.
Irregular fiber cross-sections alter natural vibration harmonics, requiring automated algorithm corrections to report true decitex metrics. Spinners utilize these granular data to predict yarn fineness limits and draft ratio performance.
Quality Standard
Quality control laboratories log individual fiber resonance data to establish statistical coefficient of variation values for incoming fiber shipments. Raw material specifications define maximum allowable linear density variation before lot acceptance. Test results attach directly to commercial inspection certificates for high-count yarn production.
