The brand with a quality guarantee

The USTERIZED® logo identifies yarn from spinning mills with state-of-the-art quality management. USTERIZED® mills spin yarns of consistent quality. That is assured by testing and clearing with USTER® instruments, underpinned by a comprehensive quality management process.

USTERIZED® auditors examine the certified mills regularly. They scrutinize their quality management systems and processes and highlight any deficiencies in the mill’s quality systems, suggesting effective remedies. Companies seeking USTERIZED® re-certification must pass the stringent audit every time.
