Every good spinner understands the importance of testing cotton fiber quality. It's the basis for critical decisions which impact on yarn quality and, ultimately, the mill's ongoing profitability. The USTER AFIS PRO 2 fiber testing instrument from Uster Technologies is the ideal process optimization tool, and its superior performance and accuracy is now proven in a series of independent global trials.

The production of quality cotton yarns is a complex task, so it's vital that test procedures, and instruments used, must be accurate and reliable to have any value in today's demanding textile marketplace. Accuracy, in this context, means conformity with global standard measurements, within accepted tolerances.

For spinners, fiber test results influence choices about which raw material to select and how to process it. Machine settings, production rates and waste levels are all dependent on key fiber parameters being measured and reported as accurately as possible.

Fiber testing instruments such as the latest USTER AFIS PRO 2 are now viewed as essential tools for determining processing options, but users also need evidence that the data provided is not only accurate, but also can be matched, compared and benchmarked against measurements from others with the same instrument type.

ICA Bremen Round Trials provide independent checks on instrument accuracy

Objective, independent analysis of test performance is the best guarantee of effective results, and the world-renowned cotton authority ICA Bremen offers a regular program of methodical sampling to fulfill this need. The ICA Bremen Round Trials are conducted three times a year, involving as many as 200 textile laboratories worldwide.

Each lab tests a sub-sample of material, the master-sample being tested by ICA, to compare test results from various instrument types. The labs return their results to ICA under a code number, to preserve anonymity. The statistics are evaluated and a report circulated to the participating labs, enabling them to match their test performance against the general pattern.

In this way, the Bremen Round Trials provide a regular check on the accuracy and reliability of instruments used by participants. In the case of USTER, the major instruments involved in the trials are the HVI test system for cotton fiber classification and the AFIS process optimization tool.
