The line concerning yarn dyeing on package is the most innovative one and it is systematically updated. The consolidated HPF-HS version with Flex 10 and Flex D is equipped with all the new dosing and process control systems, already installed on TS series. Moreover, the new Software associated with HPF-HS functions ensures processing on synthetic yarns - even at very high tenacity - on twisted wools and cashmere or on stretch yarns with an even more increased reproducibility and evenness. Available also in the AcquaZero version.
