Imaging Technology :End of Uster And Classimat Testing

The end of Uster, classimat testing and other other such numeral values to the evenness of the yarn is not so far.

All it would take is a Hand Phone to image out the yarn and the first visual will directly compare against the good yarn visual. The faults will now be visible faults and not a simple number.

The Imaging Technology can now see through the structure of the yarn and give a graphical display of   the evenness of the yarn.

Yarns will then be classified as Class I, Class II and Class III spinning , depending upon the visual co-ordinates of the image. The image analyzer will further classify for a given length, the axis parrellization   , the nodes and the troughs.

The Yarn Hairiness will now become the most central quality parameter, as this will show up distinctly

The new online test results will not have thin places and thick places or neps, but the Delta value of the width of yarn in Mu values, which is above and below the mean value of the yarn. The evenness will then be a percentage value of say 95% even and 5% uneven. Rated as Class I yarns.

For one time, the big machine makers should feel happy that now visually their machine performance can clearly demonstrate the improvement in yarn quality . The spinner will also feel happy that he can  clearly compete against other spinners on visual delight.

The imaging cameras will be installed right after the fault clearer. 

Of course, one can program the system to stop the machine, if consistently the set parameters get exceeded to ensure that only Class I yarns get made.

In case of yarns for dyeing, one will be able to visualize the porosity of the yarn, the depth of the color and the uniformity of the color.

The fluid imaging technology is already there and this can be exploited now to reuse the dye-bath by uploading the dyes to the desired level and adding the auxiliaries and running the same liquor again for the next batch and so on.  This can save millions of dollars to the dye house and of course huge eco saving. However, by its own self  I don't think dye house have the intelligence to understand all these new technologies, till someone offers a plug in system.
