Switzerland's Uster Technologies to participate in India ITME 2022

"In Hall 9, visitors would be able to quickly recognise the booth C5 from distinctive white and red design. Uster looks forward to being the host for visitors at the upcoming show in India," the company said in a media release.

Based on the fact that profitability is a basic requirement for spinners, Uster Technologies has examined contamination-controlled spinning from the viewpoint of one such well-known concept – the Pareto Principle – and has assessed its validity in a yarn production environment.

In the late 19th century, Italian economist Vilfredo Pareto made the initial observations on which the Pareto Principle is based. Also known as the 80-20 rule, it suggests that in many cases only 20 per cent of the effort put in will account for 80 per cent of the result. This imbalance between input and output has been used in business to choose priorities and focus on the most effective areas to bring the greatest reward. Although not a hard-and-fast rule, the Pareto Principle can help to increase productivity and efficiency in industrial settings.

Specifically, it can be applied to determine ‘best practice’ in some elements of spinning when focused on contamination control.

Experienced spinners know that contamination control in the blowroom exactly follows this principle. Correct positioning of the fibre cleaning system – at the point where the fibres are most open – is crucial. Contaminants might otherwise be hidden inside bigger tufts, but not with Uster Jossi Vision Shield at the fibre opening stage.

Uster Jossi Vision Shield is backed by 20 years’ experience. Conventional camera-based systems cannot match its performance. Operating across a much greater wavelength, Uster’s spectroscopes can find contamination even within the ‘invisible’ range of IR and UV light. Fragments of contamination in light pastel colours and white also pose no problem.

Any remaining contamination or defects will then be identified and removed by the final-stage check at the Quantum 4.0 yarn clearers, which will ensure the yarn meets customer requirements. The good news for spinners wondering about capacitive or optical clearing for a new production line, or for retrofit, is that Uster Quantum 4.0 has both capacitive and optical sensors, applicable to different yarns and changing conditions.

The second part of the Pareto concept – that the ‘other’ 20 per cent of the results require 80 per cent of the effort, does not actually apply for contamination-controlled yarn production. The principle here is ‘managing remaining contaminants in yarns at minimum possible cost’ – and the solution is total contamination control (TCC), which achieves far more than any 20/80 correlation. Total contamination control means precisely controlled contamination levels in yarns, with minimum waste as an integrated solution, the release added.

Total contamination control balances ejections in the blowroom along with cuts in winding in the most advanced way. Uster Jossi Vision Shield and Uster Quantum 4.0 are two perfectly linked systems in the production process, minimising the risk of foreign matter quality issues and focusing on defined quality and profitability.

"TCC is an Uster value module with quality expert, which also reveals optimisation potential to save costs. Data from Uster Jossi Vision Shield and Uster Quantum 4.0 combined with Uster’s long experience in contamination control, answer the following key questions in practice. What is the right level of contamination removal? How does fibre cleaning and yarn clearing achieve consistent levels of contamination that will satisfy the customer requirements? And how does it prevent waste of good material?," the release further added. 

Uster’s preventive yarn clearing solution follows its own rules: preventive means that there is no 20 per cent or anything remaining needing extra effort, but there is security. The new combined clearing and enhanced detection modes protect yarn quality while reducing cuts at the same time.

Furthermore, disturbing defects cannot pass, so that issues in downstream processes are prevented. Upstream, connectivity to Uster’s quality management platform contributes to ‘preventive yarn clearing.’ Perhaps preventive yarn clearing could be called a 100/0 rule, said Uster in the release.
