ensures perfect registration and alignment throughout, even for delicate and unstable fabrics such as knits or fine silks. If required, this machine may also pre-heat, dry or set the printed fabric, before finally rolling-up the output smoothly and with even tension.
Ichinose uses a conveyor belt to transport and align the textile substrate.
The conveyor belt carrying the fabric gently moves ahead for inkjet printing operation. The print head nozzles are set up right above the carrier belt, and the cloth printed with the inks sprayed from the head nozzles. This can prevent the inks from bleeding onto the cloth. After printing operation the cloth at the exit end is released from the conveyor belt. The conveyor belt can be cleaned whenever necessary
The average particle size of disperse ink must be approx. 0,5 micro meter or lower in order to avoid clogging of the nozzles. Electrostatic deflection systems also require that the ink is electrically conducting which is difficult to achieve in organic solvent based systems.
*Avoids drying out of the nozzles
