Fabric thickness is defined
as perpendicular distance through the fabric, which determines the dimension
between the upper and lower side of the fabric.
Determination of thickness
of fabric samples in laboratory is usually carried out with the help of a
precision thickness gauge.
In Fabric Thickness Gauge, the fabric whose thickness is to be
determined is kept on a flat anvil and a circular pressure foot is pressed on
to it from the top under a standard fixed load. Then the Dial Indicator
directly gives the thickness in mm.

Working Procedure of Fabric Thickness Gauge:
- The fabric sample that is to be measured is kept on an anvil.
- The press foot is gently lowered on to the specimen.
- The reading is taken to get the thickness of the specimen.
- The flat circular indenter of the micrometer exerts the specified pressure on the fabric sample.
- The above procedure is repeated to obtain the values of thickness at least at 3 different locations.
- The mean value of all the readings of thickness determined to the nearest 0.01m is calculated and the result is the average thickness of the sample under test.
