Circular Locus Tester

The Circular Locus Tester accurately evaluates the pilling resistance of fabrics, pure yarns, and blended yarns in both knitted and woven forms. During testing, the operator presses the fabric specimen against an abrasive surface and moves it in a circular motion under controlled load and speed. After completing the set number of cycles, the user visually assesses and grades the degree of pilling.

The tester delivers consistent and repeatable results, helping textile manufacturers, research laboratories, and quality control departments accurately analyze fabric surface durability.
