TESTING OF FABRIC THICKNESS
Fabric thickness:
The thickness of any compressible material such as woven fabric, knitted fabric, and non woven fabric is defined as the thickness of such kind of material when the fabric specimen is placed between two plane surfaces of incompressible metal. The surfaces of the circular pressing plates are kept parallel to eachother. The specimens is tested under specified pressure.
Apparatus used:
1- Fabric thickness tester.
2- Scissor.
3- Fabric.
4- Marking pen.
Specimen preparation:
The size of the specimen is kept according to recommend standard. Normally, the 10 mm diameter of specimen is cut with the help of tample. 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 standard. You can see in below figure:
Testing procedure:
This is 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 pressure release lever. A standard pressure of 100 grams per square centimetre is applied to the specimen. It may be vary according to recommend standard.
When the circular pressure foot presses the specimen, the thickness of the fabric measured with the help of micrometre mounted in the tester. All the test specimens are tested one by one as per above mentioned method. The mean of the all results is calculated. The fabric thickness is expressed in mm.
Precautions:
1 - The specimens should be prepared accurately. The specimen's size should be kept as per recommend 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.
