Uster’s innovations in Shanghai

Best of capacitive and optical sensors for intelligent yarn quality control.

Uster will introduce its new Quantum 4.0 yarn clearer, Q-Bar 2 formation monitoring system and Quality Expert software, with its latest Mill Dashboard feature, at the forthcoming ITMA Asia + CITME 2021 in Shanghai from June 12-16.

The Uster Quantum 4.0 yarn clearer offers the best of two sensor technologies – capacitive and optical – for intelligent yarn quality control.

A simple capacitive/optical switch allows greater flexibility in the yarn types which can be produced, while also dealing with factors such as humidity variations. Both sensor channels can also be used 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.

For compact yarns in particular, spinners can trust the Quantum 4.0 to deal with any 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. In addition, yarn density is monitored continuously and after every splice.

As well as identifying issues at winding, defect prevention at source is now possible – a massive advantage provided by the clearer’s new Quantum Expert. Thanks to many extra intelligent analytical features, the Uster Quantum Expert enhances process control and prevents defects through total contamination control and ring spinning optimisation.

For weaving, Q-Bar 2 is best described as a formation monitoring system, positioned directly at the interface of warp and weft threads on a loom. See further details here.

The introduction of the latest Mill Dashboard meanwhile might seem like just another of many new features within the Uster Quality Expert system, but it presents key data directly to key individuals in the spinning mill, allowing them to react rapidly to any quality deviations.

The latest release of Uster Quality Expert allows all key quality parameters from laboratory and in-line instruments to be displayed, targeted to individual needs and preferences.
