Preparation of the samples :

1.      The fabric is washed or dry cleaned.

2.      Use the template to prepare 4 specimens 125mm square. Prepare 2 in each direction, so that they do not contain the same set of warp and weft threads. Mark through one of the slots in the template to give a line 12mm from the cut edge.

3.      Place a line on the reverse of each sample indicating the warp/wales direction before taking from the main piece.

4.      Fold the specimens in half, face to face. Sew a 12mm seam parallel to the fold along the marked line.

5.      Turn the 4 specimens face outwards.

6.      Trim all specimens at each end to give a finished length of 113mm.

Conditioning :

Condition the samples for a minimum of 4 hours in an atmosphere of 20 + 2°C and 65 + 4% RH.

Test Procedure :

1.      Before commencing the test, clean the inside of each box with the soft brush /    air-cleaner to remove fluff and debris from the previous test.

2.       Place the 4 prepared test specimens in the same pilling box. Close and secure the lid.

3.      Tumble the tubes in the box for the number of revolutions as per the performance standard.

4.      Testing will be continue 5 hours.

5.      Remove the samples from the box.
