USTER® TESTER 5 The yarn inspection system Fancy Yarn Profile Gabriela Peters, June 2007

USTER® TESTER 5 The yarn inspection system General

USTER® TESTER 5 Highlights - Fancy Yarn Profile Precise sensor technology 17 NEW New unique reports

USTER® TESTER 5 USTER® Fancy Yarn Profile 18 • Quality control is extremely important when it comes to meeting yarn specification. • The new unique Fancy Yarn Profile on the USTER® TESTER 5 analyses slub yarns for their quality. • It has never been easier to obtain all quality-relevant information of a slub yarn.

USTER® TESTER 5 USTER® Fancy Yarn Profile • There are three major requirements for a consistent slub yarn. – Constant quality – Yarn without mass decreases before and after a slub – Yarn without disturbing pattern in the yarn 19

USTER® TESTER 5 The yarn inspection system Features

USTER® TESTER 5 USTER® Fancy Yarn Profile • New parameter such as slub length, slub distance and mass increases support the evaluation of the numeric results Slub length 21 Slub distance Mass increase

USTER® TESTER 5 USTER® Fancy Yarn Profile • NEW mass diagram special for slub yarns Marks all slubs which go in the calculation Mass decrease before and after a slub: measured value must before or after 3 cm and must 30% smaller as the reference value 22

USTER® TESTER 5 USTER® Fancy Yarn Profile • Three types of spectrograms are now available - Normal spectrogram - Only slubs - Slubs removed 23

USTER® TESTER 5 USTER® Fancy Yarn Profile • For the first time it is possible to show a spectrogram with removed slubs to properly analyze yarn also for periodical faults Periodical faults • Slubs removed • Slubs only 24

USTER® TESTER 5 USTER® Fancy Yarn Profile • 25 USTER‘s famous scatter plot for the best overview about the slub yarn quality

USTER® TESTER 5 USTER® Fancy Yarn Profile • 26 Settings after a test allow the specific evaluation from more than one slub population

USTER® TESTER 5 USTER® Fancy Yarn Profile • 27 This excellent tool helps to filter disturbing mass increases to show only the evaluation of the slub distribution

USTER® TESTER 5 USTER® Fancy Yarn Profile • 28 The customized classification matrix shows perfectly the distribution as a numerical count of the slubs

USTER® TESTER 5 USTER® Fancy Yarn Profile • 29 A set of histograms gives you graphical information about the slub yarn

USTER® TESTER 5 USTER® Fancy Yarn Profile • 30 The slub sequence diagram shows the slubs with the succeeding slub distance, this unique tool represents the complete cycle of the slub yarn

USTER® TESTER 5 USTER® Fancy Yarn Profile • Information from scatter plot and histogram are combined in the three dimensional report that indicates mass increase, slub length and frequency 31

USTER® TESTER 5 The yarn inspection system Benefits

USTER® TESTER 5 USTER® Fancy Yarn Profile Benefits and Advantages • Information related to daily quality control • Information related to fabric appearance • Information regarding the loss of production efficiency in knitting or weaving 33

USTER® TESTER 5 USTER® Fancy Yarn Profile • Fancy Yarn Profile shows a missing slub very clearly in the diagram and in the sequence diagram 34

USTER® TESTER 5 USTER® Fancy Yarn Profile • Machine settings are very sensitive and depend on many parameters such as motor power • The example shows a fault of the spinning frame • The slubs are very narrow and the machine had no time to increase/ decrease the delivery speed, resulting in combined slubs 35

USTER® TESTER 5 USTER® Fancy Yarn Profile Long-term reports • Can be defined for all numeric values 36

USTER® TESTER 5 USTER® Fancy Yarn Profile • Disturbing patterns makes the fabric useless • With the support of diagram, scatter plot and the sequence diagram disturbing patterns are detect very easily 37

USTER® TESTER 5 USTER® Fancy Yarn Profile • Spectrogram analysis is a must for the daily quality control • Now for the first time ever it is possible to show a spectrogram for a base yarn separate from the desired slubs • This allows periodical mechanical faults to be eliminated • Slubs only Analysis of base yarn for periodic faults 38 • Slubs removed

USTER® TESTER 5 USTER® Fancy Yarn Profile – Weak places create lost production in weaving and knitting processes – In diagram of the Fancy Yarn Profile mass decreases are marked and show if machine stops during further processes may occur – In addition to the diagram, the sub sample table details the number of the mass decreases 39

USTER® TESTER 5 The yarn inspection system Summary

USTER® TESTER 5 USTER® Fancy Yarn Profile - Overview Fancy Yarn – Basic Fancy Yarn – Option • Diagram (with marked slubs and (without marked slubs) • Normal Spectrogram • Scatter Plot mass decreases) • Spectrogram (normal, only slubs and only base yarn) • Scatter plot • Classification matrix and classification matrix user defined • Histogram (slub length, slub distance, mass increase) • Slub sequence diagram • 3 D Plot • Slub yarn configuration 41

USTER® TESTER 5 USTER® Fancy Yarn Profile - Sales Options • The USTER® Fancy Yarn Profile is available on USTER® TESTER 5 S 800 and S 400 • The USTER® Fancy Yarn Profile is upgradeable for all current USTER® TESTER 5 42

USTER® TESTER 5 USTER® Fancy Yarn Profile 43 • The new USTER® Fancy Yarn Profile sets the standard for slub yarns measurements • Through a multitude of new reports, the USTER® TESTER 5 now makes it simple to determine the quality of slub yarns precisely
