UNCOVER VARIATIONS IN HAIRINESS –
AVOID PRODUCTION DOWNTIMES |
Around 15% of undesirable phenomena in fabric are caused by hairiness defects. Differences in the number of fibers of different lengths tell you nothing about unwanted variations in hairiness within a yarn batch or package. With the USTER® HAIRINESS hairiness test, you benefit in more ways than one – reproducible measurements, optimum downstream processes and complaint-free products.

MINIMIZE COMPLAINTS – OPTIMIZE COSTS |
For checking spinning settings, regular laboratory inspection of the spun yarns remains extremely important, despite the presence of online monitoring. This means you have to test long lengths of yarn for hairiness and variations in hairiness – USTER® supports you with this important possibilities. Hairiness defects are not noticeable in the mass of yarn. To find them despite this, USTER® HAIRINESS is supported by diagrams and spectrograms. These hairiness variations can result in shade variation after dying. |

ACCEPTED – USTER® STATISTICS |
|
The USTER® OH SENSOR is now standard equipment for the measurement of yarn hairiness in over 80% of all spinning mills. Only the USTER® OH SENSOR offers reproducible and comparable hairiness measurement – USTER® HARINESS, the unique standard that’s accepted all over the world.
USTER® HARINESS eliminates uncertainties in the yarn-trading process. Yarns spun in the compact spinning process show up to 50% lower hairiness – the USTER® STATISTICS optimizes the trading process.

BETTER QUALITY – GREATER PROFIT |
Definitions of visual quality are now established in the spinning industry. Differences in hairiness are either visible from the original yarn or with the help of USTER® GRADES – however, visual impressions are subjective and only accepted to a limited degree in the yarn trade. With USTER® HARINESS, you benefit from standardized values and a measurement that can additionally be substantiated by accepted values!

USTER® HAIRINESS – AUTOMATED
MEASUREMENT AND REPRODUCIBLE VALUES |
In contrast to mechanical alteration of yarn hairiness, yarn compacting through the spinning technique depends less on the direction of feed. In this, the use of vacuum in the spinning triangle achieves more effective integration of the fibers – all fibers are positively controlled before the twist is applied. The result is a significantly lowered hairiness and a visibly improved evenness.
With the USTER® TESTER 5 OH SENSOR, you not only measure hairiness but also detect errors in the vacuum system of the compact spinning position – with results that can be reproduced at any time and completely independently of the operating personnel. |

USTER® HAIRINESS – THE WORLDWIDE-ACCEPTED STANDARD FOR YARN HAIRINESS |
|
Hairiness is an extremely important parameter, both in the spinning mill and in the trading of yarn. It is therefore essential to be able to measure hairiness to a quality standard that is both reproducible and accepted throughout the world.
Automated measurement of yarn hairiness demands a great deal of the measuring principle and assessment of the results. Due to the constant changes of feed direction in the downstream processes, classifying the length of protruding fibers is extremely difficult and is not reproducible. USTER® HARINESS has now become established throughout the world as the standard for the measurement of hairiness in yarn – everyone knows what you’re talking about.
