Martindale Abrasion Pilling Tester HD-353-4 The Abrasion Pilling Tester can test the abrasion resistance and pilling performance of various structural fabrics. The sample is subjected to low-pressure continuous reversing friction with a certain friction material, and its wear and pilling degree can be compared with the standard parameters for evaluation. The instrument adopts a movable sample fastening component, which can take out a friction sample at any time without affecting other samples. It is a fastening method approved by BSEN ISO12947-1:1999. The instrument is equipped with electronic preset batch timer and total counter, sample holder and loading device (in line with international test standards), and can provide 4, 6, and 8 models.
