Also known as the 80-20 rule, the Pareto Principle suggests that in many cases only 20% of the effort put in will account for 80% of the result. Although not a hard and fast rule, this 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.
Contamination control in the blowroom exactly follows this principle. For this reason, Uster Technologies AG, Uster/Switzerland, will be presenting its spinning solutions at the 11th India ITME from December 8-13, 2022, in Noida/India.
Correct positioning of the fiber cleaning system – at the point where the fibers are most open – is crucial. Contaminants might otherwise be hidden inside bigger tufts. Operating across a much greater wavelength than conventional camera-based systems, Uster spectroscopes can find contamination even within the ‘invisible’ range of IR and UV light. Fragments of contamination in light pastel colors 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 from Uster. For a new production line, or for retrofit, they have both capacitive and optical sensors, applicable to different yarns and changing conditions.
The second part of the Pareto concept, that the ‘other’ 20% of the results require 80% of the effort, does not actually apply for contamination-controlled yarn production. Total Contamination Control (TCC) means precisely controlled contamination levels in yarns, with minimum waste as an integrated solution.
TCC 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 2 well-linked systems in the production process, minimizing 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 optimization potential to save costs.
This preventive yarn clearing solution means that there is no 20% or anything remaining needing extra effort. 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.
