Switzerland-based Uster Technologies, a leading provider of quality management solutions from fibre to fabric, offers a combined solution for nonwovens quality control that will be on display at the Index20 trade show to be held from October 19-22, 2021 in Geneva, Switzerland. The company will be showcasing its products at Booth 1402 in Hall 1.

EDANA and INDA, the leading global nonwovens associations, recently issued the 2021 edition of their ‘Standard Procedures’ guidance for nonwovens and related industries. These authoritative documents aim to define, in technical terms, relevant products – including 107 individual test regimes. This special article covers a range of intermediate measures and test processes for spunlace and other nonwoven technologies – leading ultimately to products with top class designations.

Nonwoven materials can’t really be better than the fibres they are made of. But there is a real threat to the quality of nonwovens caused by contamination. Fibre cleaning is the solution and bundle size is the key detail: small contaminant particles can hide inside bigger bundles, making them especially difficult to locate when the material is more compressed. Uster Jossi Vision Shield N is ideally positioned in the line to overcome this, directly behind the fine opener. This ensures that the fibre bundles pass the spectroscopes in their most open state, the company said in a media release.

Uster Jossi Vision Shield N 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 readily copes with the high output of standard production lines. For best detection results, the fibre cleaner is tuned to identify the typical contamination types in nonwovens, including coloured fibres.

In Europe last year, medical applications recorded an increase in demand of 118 per cent and wipes personal care plus 22 per cent. These are the top two growing segments according to EDANA – and they are also the ones showing a trend towards zero tolerance levels for defects larger than 1 mm. While other technologies use conventional colour cameras, the built-in spectroscopes of Uster Jossi Vision Shield N operate on a much greater wavelength range. This enables detection of contamination within the ‘invisible’ range of infrared and ultraviolet light, and even contamination fragments of the same or similar shade as the fibres themselves – down to the fineness of a human hair.

Uster Jossi Vision Shield N is made in Uster, Switzerland. So is Uster EVS Fabriq Vision N, the nonwovens quality assurance system which ensures a consistently high rate of fault detection using automated inspection during the production process. “Our customers aim for confidence in delivering the right quality to strengthen their own customer relationships. With Uster EVS Fabriq Vision N, they can guarantee quality compliance and protect their business,” said Grégory Winiger, area sales manager at Uster Technologies.

The Uster nonwovens systems lead to total fabric quality assurance by using automated control during intermediate inspection. Uster EVS Fabriq Vision N locates any visible faults objectively and consistently. Defects in every roll are located and recorded in a defect map, at full line running speeds.

Uster EVS Fabriq Vision N enables seamless integration of an inspection system into any production process – and ideally into nonwovens manufacturing lines – detecting contamination, holes, irregularities and any other defect. Installation is simple and flexible: a fixture bar bridges the full width of the process line, holding as many spectroscopes as required for the application, the release said.

“With improved quality, as well as improved first-quality efficiency, Uster EVS Fabriq Vision N offers an additional advantage for all applications,” said Winiger. The combination of a full map of fabric defects and the cut optimisation module means more first-quality rolls can be produced and bad quality taken out.

The combination of Uster automated contamination removal and quality assurance is the best solution today for nonwovens producers to protect quality, avoid material waste and take full advantage of the potential for process optimization. “The combination of Uster Jossi Vision Shield N and Uster EVS Fabriq Vision N means that Uster can offer a complete and unique quality monitoring solution for the nonwovens industry,” added Winiger.
