USTER has launched the new USTER Jossi Vision Shield N fibre cleaning system. USTER offers full control of contamination and defects by combining two automated solutions for quality monitoring. USTER offers high-technology instruments, systems and services for quality control prediction, certification, and optimisation in the textile industry.
Nonwovens production lines demand tough standards. Material throughout is very high, while wear and tear on machines through abrasive fibres adds extra constraints. These challenges are met by the Jossi Vision Shield N fibre cleaning system, which was especially developed for the high-output synthetic nonwovens industry. Thanks to its wide and deep channel, Jossi Vision Shield N is designed to be installed on high-production lines, according to a press release by USTER.
The machine is built with the most durable materials, using stainless steel to prevent abrasion in areas which come into contact with the fibres. The machine is the result of surveys, close collaboration with international nonwovens companies and countless hours of field tests. Installation is easy, since the fibre cleaner’s slim design fits perfectly into existing lines – and it readily copes with the pace of standard production environments. For best detection results, the fibre cleaner is tuned to identify the typical disturbing contamination types in nonwovens, including coloured fibres, metal, or wood particles and grease deposits.
Though Jossi Vision Shield N is brand new, it is based on well-proven technology. In fact, it’s acknowledged as the leading fibre cleaning system specifically adapted to the needs of the nonwovens industry. Introduced to the market 20 years ago, there are 3,500 systems currently installed worldwide and the technology has been continuously improved. The field of experience was in spinning mills processing cotton. In that sector, contamination is a serious issue – and is even more critical for producers of fleece for the hygiene and medical applications.
While other technologies use conventional colour cameras, the built-in spectroscopes of the new machine operate on a much greater wavelength. This enables it to find contamination even within the ‘invisible’ range of infrared and ultraviolet light, even detecting contamination fragments of the same or similar shade as the fibres themselves – down to the fineness of a human hair.
Extra assurance comes wit h the Quick Teach feature, in which the machine automatically ‘learns’ the correct colour of each new raw material lot within seconds. This prevents any annoying false ejections when changing lots. Additionally, it is possible to view pictures of every ejected contaminant on the touchscreen, to verify that only the required material is removed.
The nonwovens industry today faces constantly increasing quality requirements. Trends such as a greater focus on product quality by end-users are driving demands for more comprehensive control over contamination, and also over defects arising in the production process. At the fibre preparation stage, Jossi Vision Shield N ensures the best possible initial inspection and removal of contamination. Then, at the end of the production sequence, EVS Fabriq Vision N handles automated detection and marking of all the main defects caused during production – and of any remaining contamination.
