ICI Pilling Box Tester is used to test the pilling performance of wool knitted or wool-like knitted products. The test standards are GB/T4802.3, ISO 12945.1, BS5811,  IWS TM152.

ICI Pilling Box Tester Test principle:

The sample tube with the test sample is placed in the pilling test chamber, the instrument is started, and the sample is flipped and rubbed in the box body. After the number of rollovers is agreed, the sample is taken out for rating.

Sample preparation:

(1) Pretreatment: If pretreatment is required, the sample may be washed or dry-cleaned by a method agreed by both parties. (Precaution is recommended to protect the friction surface of the pilling box and the sample tube from residual lubricant or finish on the fabric)

(2) Four specimens were cut from the fabric sample, the size was 125 mm*125 mm, and another swatch of the same size was cut as a comparison sample for the rating. Two specimens were folded inward along the longitudinal direction, and two specimens were folded inward along the lateral front surface, and were sewn with a sewing machine at a distance of 12 mm from the side.

(3) The suture sample is everted and the front side faces outward. Cut 6mm ports at both ends of the sample tube to remove the sewing deformation. The sample was placed on the polyurethane sample tube and fixed with PVC tape (to ensure that the ends of the polyurethane were 6 mm bare, and the length of the tape should not exceed 1.5 times the circumference of the polyurethane tube).

(4) Conditioning.

Experiment procedure:

(1) Cleaning the pilling box

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

(3) Preset rotation number. Number of agreements. In the absence of agreement, the coarse fabric was turned over 7200 rpm and the fine imitation fabric was turned over 14400 rpm.

(4) Start the ICI Pilling Box. After the test is completed, take out the sample, go out to suture, and rate the sample.
