Description
Product Introduction:
This instrument is designed by incorporating the advantages of similar devices both domestically and internationally. It features an elegant, streamlined appearance and simple operation. Its microcomputer system supports two counting modes, offering intuitive, user-friendly interface and convenient parameter setting. With six test stations operating simultaneously, it significantly enhances testing efficiency. The instrument also includes two Lissajous patterns—24 mm × 24 mm and 60.5 mm × 60.5 mm—and a variety of complementary accessories, enabling compliance with multiple test method standards.
This instrument is suitable for testing the pilling and fuzzing of fabrics in accordance with standards such as GB/T 4802.2, ASTM D4970, and ISO 12945‑2. Its principle is as follows: a circular specimen is subjected to friction against a fabric of the same material under a specified pressure, following a Lissajous‑type motion trajectory; after a predetermined number of revolutions, the specimen’s pilling and fuzzing grade is assessed. It is also applicable to tests of fabric abrasion resistance according to GB/T 13775, ASTM D4966, ISO 12947, and other standards. The principle here is that a circular fabric specimen, under a defined load, undergoes reciprocal friction against a standard abrasive material along a Lissajous‑curve path, resulting in specimen failure; the fabric’s abrasion resistance is expressed as the number of cycles required to cause failure.
