The purpose of the test is to test the physical properties of the friction and pilling balls of the textile, which is a must-check item in the textile enterprise. The method is suitable for determining the resistance of the fabric to pilling and other surface defects such as hairiness and the like, and is suitable for all types of garment fabrics. This method is not suitable for silicone testing (such as durable rain and soft finishing) fabric testing, because the silicone will be transferred to the cork liner and affect the test results.

One, pilling and snagging tester experiment principle
In order to mimic the friction effect in the wearing, the sample and a small amount of gray short cotton fiber together to join the cylindrical test box and cork liner friction, the test results compared with the standard sample subjective rating.

Second, equipment and materials：
1, pilling and snagging tester
2, cork liner, thickness 1.5mm, width 146mm, length 452mm, placed in a cool dry place storage. 3.3. Air Compressor (can provide 14 ~ 21Kpa air pressure for each tank).
3, the standard laboratory standard cloth (Standard In-House Pilling Test Fabric): verify the stability of the performance of the instrument.
4, from the ball box
5, rating standards (Rating Sandard): fabric photos or fabric in kind
6, washing equipment 3.12. Dry cleaning machine
7, adhesive
8, cotton fiber, 4301tex, high quality American mountain cotton or cotton with the same specifications.
9, vacuum cleaner
10, rating box (cool white fluorescent cool white fluoeescent, the relevant color temperature 4100 ~ 4500K, can observe the sample and rating samples)

Third, pilling and snagging tester test sample preparation
1, along the direction (column) or latitude (traverse) about 45 degrees angle cut three long side of 105mm square sample, and does not contain the same yarn.
2, if the edge of loose fabric loose, cut parallel to the warp and weft of the sample, the edge of the yarn at least 5mm.
3, the sample can be washed before washing or dry cleaning.
4, with adhesive adhesive fabric front edge, the width of not more than 3mm, dry for at least 2 hours.
5, the sample and cork liner should be placed in the test before 21 ± 1 ℃, 65 ± 2% RH environment for 4 hours before being tested.
