SNAGGING RESISTANCE OF THE FABRIC:
TESTING OF SNAGGING RESISTANCE OF THE FABRIC By ICI MACE SNAG TESTER:
Now a spike ball suspended with the help of steel chain is placed over the rotating cylinder.
All required settings are done with the help of the gage.
Finally the power supply is switched on and timer resets. The required testing time 30 seconds are entered into the timer.
The technician pushes start button. The rotating cylinders get started to rotate in the clockwise direction as shown in the diagram. A spiked ball bounces randomly against the fabric as the tube rotates.
When the entered time reaches to completion, the machine gets stopped immediately. The elastic rings are taken off and this specimen's tube is dismounted from the cylinder.
This specimen is compared with snagged fabric standard or photograph.
The specimen is rated on 1 - 5 scale.
1 ( very severe snagging)
5 ( no snagging)
