Test Method: SATRA TM9

Surface water absorption and desorption

April 2019

SCOPE

This method is intended to determine the amount of liquid water a material will absorb or transmit from its surface in a specified time. The rate of desorption (drying out) can also be assessed. The method is applicable to leather, textiles, coated fabrics and fibreboard materials used for the uppers, linings, insoles and insocks of footwear. The method can also be used to assess the effectiveness that surface treatments, such as shoe polish on leather has on absorption.

PRINCIPLE

A circular test specimen is clamped across the bottom of a hollow cylinder and a specified volume of water is poured into the top of the cylinder. After a set time the mass of water absorbed by, or transmitted through, the test specimen is measured. If required the sample can be allowed to dry over a period of time and the mass change during that time is measured.
