FABRIC PILLING TEST BY TUMBLE TYPE PILLING TESTER:
The fabric is spread on the flat surface, then the template is placed over the fabric. Specimen marking is performed with the help of the template. Now specimen is separated with the help of scissor. The external fibres are removed with the help of a soft fibre brush from the specimen.
Specimen mounting on rubber tubes:
As you are seeing in the picture of specimens after cutting, the each specimen is stitched leaving stitching margin. Now a tube of specimen get resulted after stitching. The stitching side is changed by bringing it inside the specimen's tube. This fabric tube is mounted over the surface of rubber tube as shown in below figure:
The edges of the tubes are sealed by gum tape to prevent the fraying of the threads from the specimen.
The specifications of rubber tube are given below:
Rubber tube length - 150 mm
Outer diameter of rubber tube - 32mm
Wall thickness of rubber tube - 3.2 mm
Hardness of rubber tube. - 55 to 60
These rubber tubes covered with fabric are placed inside the boxes , where abrasion action takes place. The boxes get rotated continuously. The tubes fall on the rubbing pads. 18000 cycles are fixed in counter meter. When counter meter reading reaches to pre fixed reading, the machine gets stopped automatically.
Now we take out the all rubber tubes from the boxes. The fabric is removed from each tube. This fabric is rated for pilling resistance result in the tested fabric.
The level of pilling is rated on 1 - 5 scale. Rating of 1 is considered as very poor and rating of 5 is considered as no pilling in the fabric.
