USTER® - 'Think Quality' Customer Understanding

Poor quality management is mainly caused by

limited:

• Know-how

• Application of quality procedures

• Tool set

USTER® has a comprehensive under-

standing of its customer’s process and

operations!

USTER® helps to optimize efficiency, pro-

ductivity, quality, traceability and profitability!

USTER®'s extensive application know-how

offers support for different customer groups to

optimize their quality-related processes!

USTER® - 'Think Quality' Linking the entire textile supply chain

USTER® provides consulting and support services from producers through to

retailers by closing the loop for fibers & yarn quality information in the

entire value chain.

USTER® STATISTICS and USTER® systems provide a means for defining a

quality profile for yarn.

USTERIZED® spinning mills ensure conformity to the agreed yarn quality

profile.

NEW New unique reports

19

USTER® TESTER 5USTER® Fancy Yarn Profile

• 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.

20


• 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


Features

22

• New parameter such as slub length, slub distance and mass increases support the evaluation of the numeric results

Mass increaseSlub distanceSlub length

USTER® TESTER 5 USTER® Fancy Yarn Profile

23

• NEW mass diagram special for slub yarns

Mass decrease before and after a slub: measured value must before or after 3 cm and must 30% smaller as the reference value

Marks all slubs which go in the calculation


24

• Three types of spectrograms

are now available - Normal spectrogram- Only slubs- Slubs removed


25

• 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 only

• Slubs removed

26

• USTER‘s famous scatter plot for the best overview about the slub yarn quality


27

• Settings after a test allow the specific evaluation from more than one slub population


28

• This excellent tool helps to filter disturbing mass increases to show only the evaluation of the slub distribution


29

• The customized classification matrix shows perfectly the

distribution as a numerical count of the slubs


30

• A set of histograms gives you graphical information about the slub yarn


31

• The slub sequence diagram shows the slubs with the succeeding slub distance, this unique tool represents the complete cycle of the slub yarn


32


• Information from scatter plot and histogram are combined in the three dimensional report that indicates mass increase, slub length and frequency


Benefits

34


• Information related to daily quality control

• Information related to fabric appearance

• Information regarding the loss of production efficiency in knitting or weaving

Benefits and Advantages

35


• Fancy Yarn Profile shows a missing slub very clearly in the diagram and in the sequence diagram

36


• 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

37


• Can be defined for all numeric values

Long-term reports

38


• Disturbing patterns makes the fabric useless

• With the support of diagram, scatter plot and the sequence diagram disturbing patterns are detect very easily

39


• 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

Analysis of base yarn for periodic faults

• Slubs only

• Slubs removed

40


– 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

• The USTER® Fancy Yarn Profile is upgradeable for all current USTER® TESTER 5

44


• 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
