YGB511-II Type Tumble‑Box Pilling Tester (Digital Display, 2 Boxes)

Description

Product Introduction:

This instrument is used to evaluate the pilling and fuzzing performance of wool, knitted fabrics, and other fabrics prone to pilling. A fabric specimen is fitted onto a sample holder and placed in a square wooden box lined with rubber cork of a specified coefficient of friction; the assembly is then rolled a prescribed number of times. The resulting fabric is compared with standard reference samples to determine the pilling grade.

Reference standard:

Standards such as ISO 12945‑1, GB/T 4802.3, JIS L 1076, BS 5811, and IWS TM 152.
