Title:
INKJET DYEING METHOD
Document Type and Number:
WIPO Patent Application WO/2015/025524
Kind Code:
A1
Abstract:
Provided is an inkjet dyeing method for recording on fiber by ejecting an ink containing a disperse dye from an inkjet head. The inkjet head has two or more rows in which are aligned pressure chambers for generating pressure to discharge internal ink from a nozzle using a pressure applying means operated by the imparting of a drive signal. The pressure chambers are connected to each other through a shared ink chamber. The rows in which the pressure chambers are arranged are divided into N drive groups (where N is an integer of 2 or greater), and a phase difference of nAL+t is applied to drive signals applied to the pressure applying means of the pressure chambers in each drive group. n represents an integer of 1 or greater, AL represents 1/2 of an acoustic resonance period of a pressure wave in a pressure chamber, t represents a pressure wave transmission time period determined by dividing the distance between nozzles in a drive group by the speed at which sound propagates through the ink.
