Uster Technologies to inspect fabric & control quality

This is a comprehensive quality solution, ideal for spunlacing – the process most widely used for medical and hygiene products – but also effective for many other nonwovens manufacturing routes. Acquiring Elbit Vision Systems Ltd. (EVS) and integrating the company’s products into the Uster range is a move following Uster’s strategic goals. Uster aims to offer the textile industry instruments and systems to manage and improve quality from fibre to fabric.

"The EVS fabric inspection system is ideal for nonwoven applications, with its display of defect images showing type, size, and location in the fabric web. The system draws a real-time defect map covering the full width or one slit – and real-time alarms are an important benefit to production staff. Software advantages include a video album to store and maintain quality records, and grading of inspected webs or slits according to predefined customer criteria. All reports can be exported to any computer in a common database format," a Uster Technologies press release stated.

The typical configuration of the fabric inspection solution includes two camera lines, with both transmitted and reflective illuminations to cover the whole range of defects. Each inspection line is equipped with multiple cameras and covers the entire width of the web. The ideal number of cameras depends on the required resolution level of the defects.

Effective detection and elimination of natural and synthetic contamination is best achieved right at the start of manufacturing, when the fibre raw material is in loose stock form. For this, the Uster Jossi Vision Shield fibre cleaning system applies sophisticated sensors and latest-technology spectroscopes to pinpoint even the smallest particles of foreign matter in the cotton or man-made fiber raw material. All kind of synthetics and even the finest scraps of white polypropylene – otherwise difficult to pick out – are efficiently removed with the Uster Jossi Vision Shield, the press release added.

Nonwovens producers can see the complete range of Uster Technologies at ANEX 2018 – one of the largest nonwovens fabric exhibitions – in Tokyo, Japan from June 6 to 8, 2018. The solution to eliminate defects at the beginning of the production line will be kept on display. (RR)
