Uster Offers Powerful Tools To Produce High Quality Nonwovens
Powerful imaging spectroscopes in the Uster contamination sorter can detect and eject any particle that differs even slightly in colour from the main fibre, when producing nonwoven fabrics.
According to Uster, contamination in cotton or synthetic fibres can be reliably identified down to a size of one square millimetre, made possible by the Uster Jossi Vision Shield N, located directly after the fine opener.
“Many nonwovens producers are now seeing the growing business potential in recycled fibres, but getting the quality right is not easy,” Mario Siegenthaler, Product Manager Fibre Cleaning at Uster Technologies said.
“It is a proven fact that recycled fibres are still prone to infinite and inconsistent quality variations. Operating a high-performance contamination sorter in the production line is the best way to ensure an acceptable end-product,” he added.
“Uster Jossi Vision Shield N can detect defects from any light pastel, grayish or brownish base material. We use our know-how and expertise to further develop technologies in the ‘invisible’ range of IR and UV light for our imaging spectroscopes,” Siegenthaler informed.
Uster solutions have a two-way approach to superior quality control. Uster EVS Fabriq Vision N comes at the end of the production sequence, for automated detection of all the main defects arising from the process and or any remaining contamination.
Even at full line speeds, Uster guarantees reliably high levels of fault detection for nonwovens manufacturers. Fabrics are automatically inspected and graded, preventing any defects in manufacturing from reaching the end-product.
“The most common defects include unopened fibres, neps, black spots, holes and other issues, all of which are reliably detected by the Uster systems. This prevents raw material lossses, second quality production, or worst of all customer claims,” Uster said.
“Uster EVS Fabriq Vision N ensures reliable fault detection by using automated inspection during the production process and significantly reduces the risk of customer claims. The system’s ability to capture any visible faults also allows web yield to be optimised,” Michelle Salg, Product Manager Fabric Inspection at Uster Technologies also informed.
