Perfect partners for the ultimate in quality testing
USTER instruments provide the essential foundation forworld-class quality control in areas such as evenness(the USTER TESTER5) and strength measuring (USTER
TENSORAPID4 , USTER TENSOJET 4). For those userswho wish to extend their testing capabilities to includeextra features such as twist, friction, splice and countmeasurement, USTER offers excellent options withinstruments from the former ZWEIGLE company. In2009, USTER enhanced its position as world leaderin yarn testing and certification by acquiring andsubsequently further developing the ZWEIGLE range
of complementary products.
The advantages in terms of finished product quality andsaleability in yarn trading are significant, with the USTER
and ZWEIGLE ranges complementing each other perfectlyto create the ultimate quality control solution.
This synergy is illustrated superbly by the hairiness test-ing combination of the USTER ZWEIGLEHL400and theOH Sensor for the USTER TESTER5. The OH Moduleprovides the industry standard H value for yarn hairiness the only benchmark accepted in yarn trading, as well asan early-warning signal for potential production problems.The USTER ZWEIGLEHL400measures the actual hairinesslength, with its sensitive measuring system assessing thelevel and number of protruding fibers in the yarn. Thisenables spinners to forecast accurately how the yarn willperform in subsequent processes, e.g., the entanglementof warp yarns, and how it will look in the final fabric an especially useful feature when engineering a new yarntype. It also helps mills decide on traveler changes andmaintenance routines.
A further example of the ZWEIGLE extra advantage is the
USTER ZWEIGLE TWIST TESTER5, for accurate and preciseanalysis of yarn twist one of the key elements in any yarnspecification. No other parameter has a greater impact onfabric handle and feel, or on a mills overall efficiency, andthe proven ZWEIGLE expertise in this area is now enhancedas part ofUSTERs wide-ranging quality control portfolio.

Taking hairiness testing to another level
and longer, and this number allows for meaningfulcomparison and communication about hairiness levels.It also allows the spinner to forecast how the yarn willbehave in subsequent processes and how the finishedfabric will look and perform especially useful in engin-eering a new yarn. Any type of staple yarn can be testedlike cotton, cotton blends and synthetics. Even more detailis available as the USTER ZWEIGLEHL400can displaythe number of protruding fibers in seven different lengthcategories.The instrument is of particular support whenmodifying machines.
By combining the USTER ZWEIGLEHL400with theUSTER TESTER5 and its special OH hairiness sensor, thespinner can manage every hairiness-testing requirement.The OH Module provides the H-value the acknowledgedindustry benchmark for hairiness, used in yarn-tradingcontracts and also acts as an early-warning mechanismat the production stage.
Together, the two instruments amount to an integrated totalsolution for all hairiness-testing requirements.
The hairiness of a yarn has a major impact on virtuallyevery aspect of fabric quality across a wide range oftextile end uses. The appearance and durability of thefabric are affected, as well as the productivity andefficiency of further manufacturing operations, by thedegree of yarn hairiness.
The latest USTER ZWEIGLEHL400hairiness tester takesthe globally established ZWEIGLE S3 hairiness valuemeasurement to the next level. The instrument offers bene-fits in terms of improved accuracy and it now operates
eight times faster than previous instruments, with a testspeed of400 m/min. So the task of hairiness analysis isno longer a bottleneck in the lab. The speed upgrademeans more tests can be carried out and process controlspeeded up, while the instrument fits with the testingcycle of the USTER TESTER5.
In addition the measurement is now independent fromthe operator influence due to the automatic calibration.The well-known ZWEIGLE S3 figure for the hairiness of ayarn i s ba sed o n the number of pro trudin g fib ers o f3mm

Tensioning technology the key toaccurate twist testing
Buyers and sellers of yarn know that twist is one of the mostimportant parameters in specifying a yarn for many textileapplications. Not only can the twist level in a yarn affectthe look and performance of the finished product, it alsohas a direct impact on mill efficiency and profitability.Thetwist also has a significant influence on quality character-istics such as strength and elongation.
Accuracy in determining twist levels is the major requirement,and to achieve this, it is important to have the best-possibletechnological solution. That is where the USTER ZWEIGLE
TWIST TESTER5 scores, with its specially developedtensioning system a fundamental prerequisite for correctmeasurement of yarn twist.
This technical advantage means the USTER ZWEIGLETWIST TESTER5 works with the highest degree of precisionavailable today. Its flexibility means it can accommodatedifferent testing routines for various industry requirements,based on two versions: semiautomatic and fully automatic,the latter including automated sample preparation foreven greater consistency of results.
Special options include a dedicated test method forcompact-spun yarns and an exclusive semiautomatictester version for tire cord manufacturers, designed tomeet the exacting standards of the automobile industry.
The importance of measuring yarn twist is now furtherunderlined and supported in the authoritative USTER
STATISTICSbenchmarks. USTER immediately added anextra chapter on yarn twist to the USTER STATISTICSdatawhen the USTER ZWEIGLE TWIST TESTER5 was addedto the companys instrument range.

Friction measurement essential for productivityoptimization during knitting
For knitters, the friction value is a vital component in theoverall profile of a yarn, allowing them to assess how the
yarn w ill p erform during the kn itting process , and whateffect it will have on wear and tear of needles and otherelements.
What is required is an accurate evaluation of the optimumwax application for the yarn, since this information playsa decisive role in optimizing profitability: too little, toomuch or uneven wax application can mean high frictionlevels and consequent yarn breaks during knitting, as well
as causing undue component wear; while the cost of waxand other chemicals agents must be balanced against thisquality need.
The USTER ZWEIGLE FRICTION TESTER 5providesa valuable, practical solution. It features a speciallydesigned waxing-arm attachment which recreatesproduction scale waxing conditions in the laboratory allowing individual wax type comparisons to be made.The unit then determines the best wax applicationparameters for uniformity along the entire yarn length,so that friction values can be consistently analyzed.
The friction value , together with the variation betweensamples, are the basic figures provided by the USTER
ZWEIGLE FRICTION TESTER 5, and this data is valuable notonly to spinners and knitters but also to dyers in aidingdyestuff selection.
The special demands on sewing threads during high-speedstitching call for extra attention to frictional characteristics based on the quality and consistency of lubrication whichdetermine the threads sewability in penetrating the fabricsmoothly and easily. For this application, a specific version
of the USTER
ZWEIGLE FRICTION TESTER 5 is available,geared to the precise testing needs of sewing threads.

Splice measurement for winding optimization
USTER ZWEIGLE YARN INSPECTION WINDER: Humanexpertise also plays a role in assessing yarn grades,as an extra check on the standard quality values obtainedfrom traditional testing instruments. To assist in this, theUSTER ZWEIGLE YARN INSPECTION WINDER offers afast and simple overview of yarn quality data, highlightingparameters such as thick and thin places, neps, andhairiness, along with periodic faults.
The instrument interprets the numerical quality data fromtest instruments and presents it in an easy-to-read format.
USTER ZWEIGLE SPLICE TESTER4 : For yarn packages tomeet todays more challenging quality standards, strongsplices and hence splice control is a must. A typical
sales-ready Ne 30 combed-cotton yarn contains at least60 splices per 100 km half of which are due to bobbinchanges in winding the package rather than yarn faults so it is vital to monitor the strength of splices continually,if overall yarn quality is to be maintained.
To ensure splices are good enough defined as having atleast 80 % of the strength of the yarn they join the USTER
ZWEIGLE SPLICE TESTER4 is the ideal instrument. It is amobile unit that measures splice strength and elongationand can be used either in the laboratory or directly at thewinding machine, for optimum flexibility and fast machineresetting where needed.
The USTER ZWEIGLE SPLICE TESTER4 is also the idealpartner for the USTER QUANTUM CLEARER in optimizingthe entire winding process, and thus reducing the chanceof quality claims at downstream processes. It works quickly,classifying splices efficiently and simply, so that winderperformance is optimized.
