The next-generation USTER® CLASSIMAT 5 features innovative and powerful technology for defect classification and prevention. It enables both yarn producers and users to achieve significant improvements in quality consistency across an extended range of parameters.


The USTER® CLASSIMAT 5 takes the concept of defect analysis and classification to a completely new level, providing unrivaled benefits in terms of reliable, repeatable quality. A major breakthrough is the visual display of the 'yarn body' and outliers which could otherwise cause quality claims and rejections.

Outliers for periodic faults, evenness, imperfections and hairiness are pinpointed, as well as the standard analysis of thick and thin places which is already essential in yarn trading. USTER® CLASSIMAT 5 also provides standards from the previous CLASSIMAT® generations (USTER® CLASSIMAT QUANTUM and USTER® CLASSIMAT 3). Its new powerful sensor with multicolored light sources detect and differentiate colored foreign fibers, vegetable matter and, for the first time, polypropylene content.

Powerful analytical tools guide users in optimizing clearing limits, developing preventive strategies against the full range of defects, and comprehensive comparison possibilities with integrated USTER® STATISTICS benchmarks facilitate comparisons with global quality standards.
