Circular Locus Tester, to determine surface deterioration and quality of fabrics (wool, chemical fiber, mixed, kitted and woven fabrics). Using an active friction system, fabric is rubbed against a nylon brush and abrasive or an abrasive only under controlled conditions. Results of the test are achieved in minutes. The relative motion of the locus specimen grip and the abrasive platform is a circle with a relative speed of 60+/-1 r/min. The grip offers pressure to the specimen which is adjustable with a tolerance of +/-1%. For added control and safety, the machine is equipped with a self-stop switch.
Testing Standards:
GB/T 4802.1, JIG 040-1990
Product Information:
The Circular Locus Pilling Tester is used for determining the pilling and fuzzing of all kinds of fabrics to evaluable the product quality and process, such as wool, chemical fiber, mixed, kitted and woven fabrics. During the test, fabric is rubbed against a nylon brush and abrasive, or only against an abrasive under controlled conditions.
