THE YARN QUALITY ASSURANCE SYSTEM3 Application related questions3.1 What kind of yarn clearer do I need for my application?It depends on the type of application. Only Uster Technologies offers theknowledge and possibility of the best capacitive and optical clearer for themonitoring and elimination of seldom-occurring thick and thin places. Bothtypes are available with the possibility of optical clearing for foreign fiberelimination. The sales staff and specialists of Uster Technologies can helpyou to select the best option for your application.3.2 How is it possible to simplify the definition of clearinglimits?With the USTER ® QUANTUM 3 Uster Technologies has developed a completelynew, easy and customer oriented way of setting the clearing limits.At first the system can be started up with existing clearing limits. After acouple of minutes of production, the USTER ® QUANTUM 3 analyzes theyarn and proposes smart clearing limits as a starting point for optimization .The smart limits proposed consider the yarn body and the limits.For each smart limit the system provides a forecast of the number of cuts tobe expected.In case the clearing limit proposal is not consistent with the end user requirements,users can choose to open or close the setting easily with theup/down buttons or of course manually enter the settings.3.3 How can one find the optimal setting for basic clearing?Is it the same as before?With the USTER ® QUANTUM 3, finding the optimal setting is easier andfaster like never before. After evaluating the yarn over a few kilometers, thesystem proposes an optimum starting point for the clearing limits consideringthe yarn body, experience and requirements. At the same time the systempredicts the number of cuts per 100 km to be expected for the definedlimit. This is available at the touch of a button.In case the default starting point has to be changed for some reasons, userscan simply choose from a range of closer or more open limits each timelooking at the cuts that should be expected for the setting.Thus the optimum setting is based on the smart limits within a short timeAccording to the quality level of the end user required, the settings can beselected more open or close.12 (21) USTER ® QUANTUM 3
THE YARN QUALITY ASSURANCE SYSTEM3.4 What is the best basic setting for my yarn?The best setting is a compromise between quality and productivity. TheUSTER ® QUANTUM 3 proposes an optimal starting point after a couple ofminutes of production. This setting fulfils most end user needs.3.5 How can one find the optimum setting for good fabricappearance and for optimum productivity?The new unique feature of the yarn body display is showing the real characteristicof the yarn for the first time.After just 30 km of yarn running, the yarn body is illustrated and optimizationcan already be started. If higher accuracy of cut prediction is soughtone can wait for 100 km.The smart limit proposal based on the yarn body analysis and USTER ®experience will ensure that the clearing will result in no major defects leftand good fabric appearance.3.6 Which setting shall I use to make sure that no Classimatobjectionable faults will remain?The scatter plot and the yarn body are displayed according to the classes.The USTER ® QUANTUM 3 considers objectionable faults according toClassimat as a criterion when proposing clearing limits.Where needed, the clearing limits can be easily adopted manually to ensurethat no major defects will remain in the yarn (to date).3.7 What is the USTER ® QUANTUM 3 advantage with respectto compact yarns?The USTER ® QUANTUM 3 offers major advantages for compact spinners.Compact yarns are very even, and small defects can be disturbing in thefabric. USTER ® QUANTUM 3 shows the complete yarn body and hence itis possible to clearly identify and remove the outliers even if they are smalland fine. At the same time the unjustified cuts are minimized. Since yarnfaults can easily be recognized by the human eye due to missing hairiness,the USTER ® QUANTUM 3 is particularly suitable to detect smallfaults. Therefore the USTER ® QUANTUM 3 is the most powerful clearer forcompact yarns.Trials with different compact yarn producers have shown that the fabricproduced out of USTER ® QUANTUM 3 cleared yarn is the best.USTER ® QUANTUM 3 13 (21)
