FSP (Fiber Saturation Point measurements)

We measure fiber saturation point by the classical method developed by Stone & Scallan. The inability of water bound in fiber wall pore to dilute a high molecular mass dextran solution is used for calculating the fiber saturation point when an excess of liquid is present. The results are reported as the dimensionless ratio of the mass of the fiber wall water divided by the mass of the mass solids. 5-10 g of sample is required.
