Uster has launched the Quantum 4.0 yarn clearer generation for spinners. The innovation combines both capacitive and optical sensors in one, delivering comprehensive security, prevention, and flexibility. Uster offers high-technology instruments, systems, and services for quality control, prediction, certification, and optimisation in the textile industry.

The Smart Duo system offers the best of both worlds for intelligent yarn quality control and optimised profitability. It means mills can now focus on meeting the fast-moving market challenges, instead of pondering technical options. Quantum 4.0 is like a dream come true for the industry. For years, spinners have wished for a way to bring the best of different technologies together, for secure quality and maximum flexibility. Spinners can now access full security in quality control, ensuring the best clearing mode is applied. The Quantum 4.0 enables this through a simple Capacitive/Optical switch. This allows greater flexibility in the types of yarn which can be produced, while also dealing with factors such as humidity variations, according to Uster.

The capacitive and optical sensors work intelligently in tandem through an innovation known as Cross Clearing. This locates and eliminates hidden defects by means of a double check, in which the main sensor’s signal is supported by the assistance sensor. This deals with issues such as unnoticed fluff events, which might otherwise cause breaks downstream, Uster said.

A further valuable innovation with Quantum 4.0 is the Blend Mix-up option, which now enables mills to identify mix-ups of different types of raw materials. This long-awaited market request detects any wrong raw material in greige and white yarns, combating the infamous, but serious, barré effect in fabrics. Cop mix-ups can happen in mills, since differences are hardly visible to the human eye. But Quantum 4.0 stops the problem before it becomes an issue, thanks to significantly improved hardware and software, all underpinned by the Smart Duo, Uster said in a media statement.

The higher processing power of the new sensors brings additional benefits such as the enhanced Continuous Core Yarn option, which detects both missing and off-centre core continuously. Innovations in Quantum 4.0 also focus on contamination, with deeper analysis of polypropylene and foreign matter. A new PP classification gives users the overview of polypropylene content, while the Advanced FD classification now shows extra classes below the 5 per cent lines. Both these features add to the value of the contamination function, together with Total Contamination Control (TCC). Quantum 4.0 gives spinners the ultimate confidence through the intelligent interaction of capacitive and optical sensor technology. It achieves ‘one of a kind’ security levels in basic clearing, while also cutting only what’s necessary, Uster said in a press release.

As well as identifying defects at winding, preventing defects at source is also in focus with the clearer’s new expert system. The new Quantum Expert is now included in the product offering. Thanks to many added intelligent analytical features, the Uster Quantum Expert enhances process control and prevention of defects, through total contamination control, ring spinning optimisation, and the RSO 3D value module.

With Quantum 4.0, a new central Smart-Limit button enhances flexibility, since operators can adjust all available smart limits with a single tap, based on the unique yarn body concept. Each individual limit can be simply fine-tuned as preferred. Users enjoy the established Quantum workflows and embrace the new customer-centred user interface with a 16:9 touchscreen on the 7th generation control units, Uster said in a statement.
