YG133B/M Yarn Evenness Tester can be used to test evenness of yarns, roving slivers which are spun with cotton, wool,flax and short synthetic fiber. To calculate coefficient of variation(CV%) and irregularity (U%) of the mass variations of yarn rovings and slivers, etc.
YG133B/M Yarn Evenness Tester is based on the platform of virtual instrument structure. It’s a versatile and high performance testing instrument for the textile laboratory. It can be used to test evenness of yarns, roving slivers which are spun with cotton, wool,flax and short synthetic fiber.It is very important for improving and assuring quality of yarns.
Main functions as follows:
●To calculate coefficient of variation(CV%) and irregularity (U%) of the mass variations of yarn rovings and slivers;
●To measure the relative count of sample (RC)
●To count the numbers of the thin placesthick places and neps; To draw the diagram of sample;
●To draw the spectrogramand it can reflect the periodical variation of the tested sample;
●To measure deviation rate threshold curve
●To determinate variance- length curve
●To test linear density-frequency distribution curve;
●To offer visible and delicate diagram analysisand have the functions of inert test/half inert test;
●Above results can be displayed on the PC screenand can be printed by suitable printer;
●The items of print report is optionalflexible zooming to suit for different paper size;
●With optional statistics analysisit can print out all kinds of statisticsreports.
Note: when using data,spectrogram,unevenness curvevariation -length curve, deviation ratio curve and line density frequency curve tested by the tester, refer to data of Uster Statistics 2001 to analyze and evaluate the yarn quality
Note: To make sure the test accuracyshould balance the sample for 24h~48h in accordance with specified temperature and humidity in ASTM D1425-1996，ISO16549:2004 and GB/T3292-1997
Features:
1. Imported electronic speed regulating system feature with accurate rotation speed and high test precision;
2. Zooming the currently unevenness curve in several proportion to facilitate the analysis of cycle uneven quality;
3. Storing the test resulting in database to make it easy for user to carry out classified statistics and analysis with test result and enhance the quality control ability;
4. Statistic analyzing system can put out annals, seasonal report, monthly report, daily report of testing data for some material, and distribution diagram of index tendency;
5. Expert system (optional) can help user to analyze failures in the textile technology. It also can compare the yarn with USTER statistics.
