    摘要: The invention pertains to a process for determining the acidity of a washing solution for removing adhering acid or base from a fibre. The determination is carried out by using a combination of at least two different analytical methods, at least one of which is selected from the density, conductivity, ultrasonic sound, and refractive index measurements. The determination makes it possible to adjust the acidity of the washing solution in such a way that fibres with a minimum amount of adhering acid or base can be produced.
