EVENEXT 2343

3 slots for yarns (for the different count ranges) and 1 for slivers and rovings

Modular system for the upgrade to the fully automatic configuration and with the hairiness testing of yarns

(Determination of Hairiness H and standard deviation of Hairiness sH)

Equipped with stand for roving and slivers

Automatic calibration before testing

New Windows software with statistics, graphs and data storage

Numerical and graphical results compatible with the mostpopular world standards

Engineered, designed and manufactured in Italy

Results of each individual test:

• CV% and U% of mass variation;
• AVE relative yarn count: IPI with 4 channels for neps, thick places, thin places;
• CV (L)% with 7 reference lengths.

Graphic data of each individual test for the mass variations and the Spectrogram

Statistics and other results:

• Mean, range, standard deviation (s);
• 95% confidence limits (Q95%);
• IPI per 1000 m (1 km) of yarn length; overall spectrogram;
• Data and graphics saved in SQLite data base.
