Uster’s innovations in Shanghai
Best of capacitive and optical sensors for intelligent yarn quality control.
13th May 2021
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.
