u CLASSIMAT 5 The yarn classification syste

USTER  CLASSIMAT 5 – transforming the industry ® The USTER® CLASSIMAT has an impressive pedigree. For spinning mills, quality management started in 1949, one year after the introduction of the GGP yarn evenness tester. USTER created a numeric value to describe the level of yarn unevenness, the so-called U%, deriving from the German word ‘Unregelmässigkeit’, which means irregularity. This was followed by the first USTER standards in 1957, which provided classification of yarn quality into different levels, today referred to as the USTER® STATISTICS percentile levels. With the introduction in...

Quality classification – the full picture Top technology for ultimate accuracy and ease of use Parameters measured by the USTER ® CLASSIMAT have played a vital role in spinning mills and yarn trading worldwide since the instrument was first developed more than 40 years ago. The classification of yarn defects according to their size and length into 23 standard classes is used extensively to certify yarn quality, to help control spinning processes and to optimize yarn clearing at the winding stage. In the meantime, quality demands have increased enormously. A class of defects regarded as...

Three classification generations in one instrument Its ground-breaking technology means USTER ® CLASSIMAT  5 has the power to detect and classify the widest-ever coverage of defects in a new extended classification matrix. Yet, previous standards are well-established in yarn trading and the transition to the latest level is best achieved progressively. That is why USTER® CLASSIMAT 5 also provides classification values for thick and thin places from the two previous-generation instruments, the USTER ® CLASSIMAT  QUANTUM and CLASSIMAT  3 . Total compatibility with previous classification...

Outlier classification – a new standard Experience shows that only a few bad quality bobbins can cause an entire delivery to be rejected by the customer. They contain defects outside the normal distribution and known to damage fabric appearance or productivity in downstream processes. This applies to all fault categories, such as thick and thin places, unevenness, imperfections, hairiness and foreign-matter. These few bobbins are called ‘outliers’, as illustrated below. Controlling outliers using yarn clearers and preventing them by pinpointing the root causes in the spinning process is...

Full assessment of foreign-matter levels Clearing Index – powerful optimization tool High levels of foreign-matter in cotton and increasing quality expectations are the twin headaches facing spinners today. Effective control of disturbing defects is essential – and the first step is to identify and evaluate the various types and degrees of foreign-matter. Defining optimal clearing limits for each yarn clearer model to meet the expected quality is not easy. Especially when lot and material changes are as frequent as they are these days. Yet spinning mills have to ensure similar quality, even...

YARN BODY™ comparison Comprehensive comparison of yarn qualities The ‘YARN BODY ™’ is a highly-effective concept which gives an immediate visual presentation of the yarn. It brings together all the elements that make up a yarn – raw material, count, process and spinning equipment – into a single combined format. Simply put, the narrower the YARN BODY ™, the more even the yarn. There are numerous examples of the YARN BODY ™ being used to identify quality problems and implement improvements. USTER ® CLASSIMAT  5 incorporates a valuable YARN BODY ™ and foreign-matter Dense Areas comparison...

USTER® CLASSIMAT5 integrates powerful benchmarking possibilities via the globally-recognized USTER® STATISTICS or with users' own internal data. Most of the key quality parameters from USTER® CLASSIMAT 5 are covered by USTER® STATISTICS, and this benchmark data is displayed alongside the CLASSIMAT® test results. This allows mills to set targeted improvements to reach benchmarked levels. A further useful benchmarking tool with USTER® CLASSIMAT 5 matches actual test values against best results achieved for that parameter during the past year. This '52-Week Best' feature is automatically...
