Шерсть. Определение среднего диаметра волокон. Метод воздухопроницаемости
Название (англ.):
Wool; Determination of mean diameter of fibres; Air permeability method
Описание (англ.):
The air permeability test method is based on the Kozeny equation. Weighed fibres (test specimen) are introduced in a measuring chamber with known volume. Air is passed through this test specimen. A scale indicating variations in permeability of air may be calibrated in appropriate absolute units of rate of flow or pressure difference and a table or graph is provided for conversion of the observed reading into values of meandiameter of the measured wool fibres.
