TESTING OF FABRIC THICKNESS
1- Fabric thickness tester.
4- Marking pen.
The size of the specimen is kept according to recommend standard. Normally, the 10 mm diameter of a specimen is cut with the help of the temple. 10 specimens are prepared from the different places of the fabric. The specimen should not be cut near the selvedge of the fabric. The specimen is tested under 100 grams / square centimetre. The specimen size and pressure limit can be varied according to recommend testing standards. You can see in the below figure:
This is a very simple test. The prepared specimen is placed between anvil ( E) and circular pressure foot ( D). The specimen is kept under circular pressure foot precisely. The specimen should not have any wrinkle in it. The specified pressure is applied on the circular pressure foot by the pressure release lever. A standard pressure of 100 grams per square centimetre is applied to the specimen. It may vary according to recommend standard.
When the circular pressure foot presses the specimen, the thickness of the fabric is measured with the help of a micrometre mounted in the tester. All the test specimens are tested one by one as per the above-mentioned method. The mean of all results is calculated. The fabric thickness is expressed in mm.
1 - The specimens should be prepared accurately. The specimen's size should be kept as per recommended standard.
2 - The applied pressure should be selected according to recommend standard.
3 - The pressure lever should get released gently.
4 - The results should be read very carefully.
5 - The instrument should be levelled properly.
