Uster has developed the new Quantum 4.0 clearer generation. This innovation combines both capacitive and optical sensors in one – delivering comprehensive security, prevention and flexibility.

The Smart Duo system offers good intelligent yarn quality control and optimized profitability. It means mills can now focus on meeting the fast-moving market challenges, instead of pondering technical options.

Spinners can now access full security in quality control, ensuring the best clearing mode is applied. The Quantum 4.0 enables this through a Capacitive/Optical switch, allowing flexibility in the types of yarn which can be produced while also dealing with factors such as humidity variations.

Intelligent sensors in tandem

The capacitive and optical sensors work 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.

Today’s market trends show strong demand for compact yarns while Quantum 4.0 is designed to deal with the quality issues. The density feature, for example, protects mills from substandard cops caused by ring spinning malfunctions such as blocked compacting zones, or twist problems. The Smart Duo has the advantage of monitoring yarn density continuously and after every splice.

“No matter where density variations originate, be it compacting, different twist levels due to slip spindles or otherwise, Uster Quantum 4.0 takes care of it – and this is a real technical innovation,” said Katrin Hofer, Product Manager at Uster Technologies.

Preventing material mix-ups and defects

A further 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 detects wrong raw material in greige and white yarns, combating the 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 the improved hardware and software underpinned by the Smart Duo.

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-center 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% lines. Both these features add to the value of the contamination function, together with Total Contamination Control (TCC).

Quantum 4.0 has 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.

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 added intelligent analytical features, the Uster Quantum Expert enhances process control and prevention of defects, through Total Contamination Control, Ring Spinning Optimization and the RSO 3D Value Module.

Latest innovations in Quantum 4.0 protect spinners from claims and waste. The clearing technologies work with Uster’s data analysis to enable flexible data-based decisions using Application Intelligence.

Secure and user-friendly

No matter how much data is collected for analysis, Uster Quantum Expert manages the complexity while staying intuitive. 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.

The established Quantum workflows and new customer-centered user interface with a 16:9 touchscreen on the 7th generation control units are presented.
