Uster, the leading high-technology instrument manufacturer, presents exclusive new features in a special version of the Uster Quantum 3 yarn clearer to improve fabric quality.

Launched at the ITMA 2015 trade fair for textile machinery that took place in Milan in November, 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, the company reports.

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, according to the manufacturer. 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-centre at a significant level and over long lengths. This is said to enable a potential cause of fabric rejects to be effectively eliminated.

For fabrics made of mélange and coloured yarns, variations in colour and shade are critical. Uster’s advanced foreign matter sensor is designed to avoid such defects with its Shade Variation feature, available with Uster Quantum 3 Anniversary Edition.

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, according to the company. 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 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 manufacturer reports.
