The unique measuring system of the USTER® AFIS counts every fiber, neps and trash particle one by one. The fiber individualizer ensures single fiber measurement, with a gentle opening of the test material. The USTER® AFIS is the standard system for nep measurement, recognized worldwide, and used from cotton ginning to yarn manufacturing. It measures various fiber characteristics such as fiber length, maturity, trash, and nep content. Measuring Principle The measuring principle of USTER AFIS is different from that of the USTER TESTER so far as the USTER AFIS is an optical system. (Figure-1) A fiber sample of 500 mg (making into a 30 cm thin sliver form) is inserted into the fiber individualizer unit that separates the specimen into three main components: Lint: Fiber, short fibers, neps, seed coat neps. T rash & dust: Trash, dust, fiber fragments, very large seed coat with little or no attached fibers. Figure 1: Measuring principle of AFIS Report Analysis: Figure 2: An exa...
