USTER, Switzerland — January, 2016 — Exclusive new features to improve fabric quality are being introduced in a special version of the USTER® QUANTUM 3 yarn clearer. Launching at ITMA 2015, the USTER® QUANTUM 3 Anniversary Edition celebrates 50 years of yarn clearing on automatic winders. Only 300,000 of the new clearers are available, on a first-come-first-served basis from November 2015.
In line with the continuing global trend for higher quality, the USTER® QUANTUM 3 Anniversary Edition includes extra defect classes, correlated to the USTER® CLASSIMAT 5. These classes can be customized by users to cover specific faults that are no longer acceptable today. The clearers will then identify, remove and report on these defects.
Yarn Clearers For Fabric Quality
The USTER® QUANTUM 3 Anniversary Edition incorporates unique innovations to help spinners achieve better yarn for better fabrics.
The Core Yarn Clearing option was developed for yarns used in stretch fabrics. These yarns have an elastane core within an outer sheath. Unique USTER® sensors automatically identify areas in the yarn where the core component is either missing or off-center at a significant level and over long lengths. This enables a potential cause of fabric rejects to be effectively eliminated.
For fabrics made of mélange and colored yarns, variations in color and shade are critical. USTER’s advanced foreign matter sensor now avoids such defects with its Shade Variation feature, available with USTER® QUANTUM 3 Anniversary Edition. Even very small divergences from the base yarn shade can be detected and cleared.
Hairiness variations in yarn can lead to a ‘cloudy’ appearance in finished fabric, and this is another quality factor secured by the USTER® QUANTUM 3 Anniversary Edition. These clearers incorporate online measurement of true yarn hairiness, so that outlier bobbins can be removed. Additionally, mills with linked spinning and winding can now monitor the condition of rings and travelers.
Leverage of yarn clearer for mill management
A further advance with the USTER® QUANTUM 3 Anniversary Edition is its connection to the Total Testing Center of the USTER® TESTER 6. This is facilitated by integration with the USTER® QUANTUM EXPERT 3 data collection and analysis system. Information from the winding machine is combined in the Total Testing Center with accurate laboratory data. This is then interpreted to present management with practical improvement advice. Spinners can create their own tailored quality network, extending the analysis options as new instruments are connected. The resulting data can be targeted to provide valuable knowledge – such as predicting exactly how a yarn will perform in weaving.
The connection between the USTER® QUANTUM 3 and the Total Testing Center enables a total overview of mill operations. The analysis of the data will guide to better quality fabrics.
