HOw to Benefit From

all-color foreign matter detection

PRISMA’s all-color foreign matter detection provides spinning mills with new possibilities in terms of quality, profitability and raw material utilization.

The unique RGB technology achieves outstanding measuring accuracy. Previously undetectable disturbing contaminations can now be removed while the non-disturbing matter are correctly classified. Offering the most efficient foreign matter detection, resulting in flawless yarn quality, increased profitability and improved raw material utilization.

RGB technology uses the additive RGB color model to illuminate yarn in the full spectrum of light. The detection of foreign matter and organic components of cotton within their true colors opens up new possibilities for recognition and classification. Enabling monitoring of all foreign matter, smallest shade and glossiness differences in any type of yarn and color and mixtures thereof.  This allows not only the removal of everything unwanted, but also for leaving what is not disturbing. Fulfilling the ultimate goal of producing the needed yarn quality with the highest efficiency.
