NWSP 10.1 Methods for Nonwoven Absorption




NWSP 10.1


Three Standard Test Methods for Nonwoven Absorption


The NWSP 10.1 Nonwoven Absorption test method covers the evaluation of the behavior of nonwoven fabrics in the presence of liquids. In particular:

a) The liquid absorbency
b) The liquid absorptive capacity.
c) The liquid wicking rate (capillarity)

The SI values are regarded as the official standard system of measurement for this standard test method.


All samples are conditioned and tested at 50% RH and 23° C.  IPS uses a basket weighing 6.75 ± 0.25 g for the liquid absorbency test.  For the wicking rate test, IPS uses the following test intervals:  10, 30 and 60 seconds (3 interval test) or 10, 30, 60 and 300 seconds (4 interval test).
