Test principle:

Put the sample-carrying tube with the test sample into the pilling test box, start the ICI Pilling and Snagging Tester, and the samples are rubbed against each other in the box. After the agreed number of rolls, the sample is taken out for rating.

Production of samples:

1) Pretreatment: If pretreatment is required, the samples can be washed or dry cleaned by the method agreed by both parties. (Pretreatment is recommended to protect the friction surface of the pillbox and the sample tube from residual lubricants or finishes on the fabric)

2) Cut 4 samples from the fabric sample, the size is 125mm*125mm, and cut another cloth sample of the same size as the comparison sample required for the rating. Two samples were folded inward along the longitudinal front, and 2 samples were folded inward along the horizontal front, and sewed with a sewing machine at a distance of 12 mm from the edge.

3) Turn the sutured specimen inside out, right side facing out. Cut 6mm ports on each end of the sample tube. Put the sample on the polyurethane sample carrier tube and fix it with PVC tape (ensure that there are 6mm bare ends of the polyurethane, and the length of the tape should not exceed 1.5 times the circumference of the polyurethane tube).

4) Debugging

Experiment procedure:

(1) Clean the ICI Pilling Box.

(2) Put the 4 sets of sample tubes into the box, close the box cover firmly, and set the counter to the required number of rotations.

(3) Preset rotation times. Agreement times. Without agreement, 7200 revolutions for coarse fabrics and 14400 revolutions for fine imitation fabrics.

(4) Start the pilling box, after the test, take out the sample, take out the suture, and grade the sample.

Test Results Rating:

The rating box should be placed in a dark room.

Place the tested sample and an untested sample side by side in the middle of the test panel of the rating box in the longitudinal direction of the fabric (if the test sample is pretreated before testing, the control sample should also be pretreated. Correspondingly, if the test sample is not pretreatment, the reference sample shall be the unpretreated sample).

Put the tested sample on the left and the untested sample on the right. Ratings are subjective and at least 2 ratings are recommended. The appearance of the sample and the corresponding grade are as follows:

Record the number of grades for each sample, and the result of a single person's rating is the average value of the grades for all the samples. The test result of the sample is the average value of the ratings of all the personnel. If the average value is not an integer, it shall be revised to the nearest 0.5 grade and expressed with "-", such as 3-4. If a single test result differs from the average by more than half a class, the class number for each specimen shall be reported at the same time.
