Used for testing the performance of the wearing resistance,abrasion, appearance change (pilling degree/class) of the textiles and membrane materials.

2 heads button type
The KR‑843 circular‑locus fuzz‑pilling tester simulates multi‑directional friction experienced by fabrics during daily wear. Under standardized pressure conditions, circular textile specimens undergo relative circular‑path rubbing against nylon bristle brush or abrasive media. After completing preset friction cycles, operators compare sample surface fuzz‑formation and pilling status against standard rating‑photos to assign pilling‑grade.
This equipment strictly follows GB/T 4802.1 specification. Multiple hardware configurations are available: button‑type 2‑head unit, touch‑screen 2‑head variant, and high‑throughput touch‑screen 6‑head model. It is widely adopted in textile mills, garment‑making factories, home‑textile producers, material‑R&D labs and accredited third‑party testing institutes for raw‑material incoming inspection and finished‑fabric surface‑durability evaluation.
