Cleaner cotton makes quality yarns – but how can spinners be sure of removing unwanted contaminants without wasting good fiber or hampering mill productivity? The acquisition of Jossi Systems AG by Uster Technologies has created the ‘Total Contamination Control’ concept. This combination of USTER®JOSSI VISION SHIELD and USTER®QUANTUM 3 offers spinners the highest level of foreign matter detection, together with lowest possible waste, as informed by the company recently.
For the most ‘contamination-sensitive’ customers, spinners face some serious choices. They could try to source only contamination-free cotton, or attempt to locate and eradicate foreign matter manually, at the opening stage. However, neither of these options is really practical or reliable.
In fact, automatic detection and removal of contamination offers the only effective solution – even better if a doubly-secure method can control unwanted material at both the start and end of the yarn production sequence. USTER offers exactly this, combining two leading-edge technologies in Total Contamination Control. First, the USTER®JOSSI VISION SHIELD, located immediately after the fine cleaner in the blowroom, takes out contaminants during the preparation stage. Then, after spinning, the USTER®QUANTUM 3 yarn clearers operate during winding to fine-tune contamination removal to meet the customer’s quality requirements. Total Contamination Control allows spinners to meet precise yarn specifications, while also managing the mill’s own productivity goals.
