“…The gravimetric measurement is regarded as the direct and standard method to achieve average linear density of fibers. 14,18,[30][31][32][33][34] We obtained the mean fineness of PTFE split-film fibers from the cut-and-weigh method explained in the international standard, 10 and the measured results are listed in Table 1. Clearly, all gravimetric linear densities are much higher than the maximum (14.42 dtex), indicating that fineness of PTFE fibers from the cut-and-weigh measurement is significantly overestimated.…”

There are various test methods applied to measure mean linear density of PTFE split-film fibers. The measured results vary with respect to computation mechanisms, measurement parameters, and morphology and inherent properties of fibers. Five test methods and an assumption calculation were introduced to evaluate the linear densities of PTFE fibers. The experimental results show that the gravimetric method generated the highest linear density, followed by the cross-section method, theory calculation, airflow measurement, assumption calculation, and vibration method. Statistical analyses indicated that actual mean linear density of the PTFE split-film fibers is in the effective range between the maximum and minimum fineness obtained from the theory and assumption calculation, respectively. Linear density of the PTFE split-film fiber tested via the gravimetric method, cross-section method, and vibration operation were significantly different to the effective range. In the case of the airflow experiment, mean linear densities measured at high porosities are in high accordance with the actual fineness. The airflow method offers a short time to reliably measure mean linear density of PTFE split-film fibers under appropriate test conditions.

“…[6] suggested a way to use the Digital Fibrograph to derive an optical fineness coefficients which would correlate very well with gravimetric fiber fineness measurements. Earlier workers [1,2,4,6,7] have shown that the Digital Fibrograph can be used to estimate the fiber fineness, maturity, area of cross section, and specific surface area. Spin lab [8] established an equation which gives the fiber maturity index from Fibrograph.…”
