In order to pick the best yarn clearer equipment, Chinese spinner Shandong LiaochengHuarun Textile which produces super fine cotton yarn counts conducted trails on yarn clearers of various makes.

In the trial, Uster clearers were installed on 60 spindles and matched against a competitive brand clearer on similar automatic winders.

After a month, the mill which exports 50 per cent of its output to Europe assessed the trial results for cuts and remaining faults, using the Uster Classimat.

According to an Uster press release, the trials revealed that the Uster Quantum 3 left 50 per cent fewer disturbing thick and thin places in the yarn, with 13 per cent fewer cuts per 100 kilometers.

“The overall verdict was that Uster Quantum 3 had proved its ability to deliver better quality and less waste, enhancing the optimisation potential of the mill,” it said.

“Modern quality demands not only call for a perfectly cleared yarn, but must also take in the fact that only a few outlier bobbins can spoil many meters of fabric, resulting in expensive claims,” Uster noted.

“Devising a system to avoid such issues was another key objective of LiaochengHuarunin running the clearer trials,” Uster informed.

The Uster Quantum 3 measures yarn quality parameters including CV, imperfections and hairiness using the Q Data feature and is correlated with Uster Tester data.

These controls allow LiaochengHuarun to meet its goal of managing outliers in the final yarn package and in the trial; outlier bobbins collected from winding were checked again in the laboratory, using the Uster Tester.

“The laboratory tests confirmed the accuracy of the clearers in identifying these outliers and this systematic quality management, using the Q Data feature means, outlier bobbins are no longer a serious risk,” Uster explained.

Thomas Nasiou, head of textile technology at Uster said, “For spinners aiming at consistently high standards of yarn quality, systematic quality management is essential.

“We strongly recommend it as a general policy, since it is the best way to achieve both optimum quality and homogeneity of quality between and within yarn lots,” Nasiou too added.

“At the end of the day, almost all key indicators impact on quality and clearer cuts and outlier bobbins, are extremely relevant indicators for quality as much as efficiency and cost are to production,” he observed.

The Uster Group is a high-technology instrument manufacturer of products for quality measurement and certification for the textile industry.

The Group provides testing and monitoring instruments, systems and services that allow optimisation of quality through each individual stage of textile production.

This includes raw textile fibres, such as cotton or wool, all staple fibres and filament yarns, as well as downstream services to the final finished fabric.

The Uster Group provides benchmarks that are a basis for the trading of textile products at assured levels of quality across global markets. (AR)
