A fixation/transfer device for control of dye waste in a dye sublimation process. The device comprises a textile inlet, a textile outlet, a heat press or calender, an endless belt for driving the textile from the textile inlet to the textile outlet through the heat press, the heat press being held at a temperature sufficient to cause sublimation of the printing dye, and a cleaning station for cleaning the endless belt, the cleaning station being located downstream of the textile outlet and upstream of the textile outlet. The feed belt may be heated at the cleaning station so that sublimation may assist cleaning.

The invention relates to a separation, recycling and self-cleaning system of a supercritical fluid dyeing machine. The system includes a supercritical fluid medium reservoir, one or more parallel dyeing units, a high-pressure pump, a primary separator, a secondary separator and a membrane separator sequentially connected. A dyeing medium and residual dye in dyeing units can be efficiently separated and recycled simultaneously, and when the separation and recycling is finished, each dyeing unit can be directly opened so that the dyeing units and products can be cleaned after dyeing, thereby improving the production and processing efficiency of supercritical fluid waterless dyeing and achieving simple operations, complete separation, stability and reliability and a blowback self-cleaning. The invention has a broad application prospect and practical significance in fundamentally addressing generation and emission of pollutants in the textile printing and dyeing industry and realizing energy conservation, consumption reduction, emission reduction and clean production.

A conveyor-driven fabric dyeing machine includes an infiltration and rinse device. Fabric is driven by a conveyor inside a machine body of the dyeing machine and has an extremely low liquid content rate due to separation of fabric, particularly hydrophobic fabric, and liquid. The fabric might get rubbed and damaged and affected in respect of dyeing homogeneity and reduction and cleaning. Quality of the fabric may also be affected by contaminants present inside the machine body. The infiltration and rinse device includes one or multiple spraying devices mounted inside the machine body at a suitable site to receive and jet and spray a pressurized dye liquid or clear water supplied from a pump onto the fabric or the interior space of the machine body to increase a moisten degree of the fabric and also to rinse the fabric and cleanse the interior of the machine body.

A liquid ejection device includes a liquid ejection unit having a first nozzle group configured to eject a first liquid to a cloth conveyed, and a second nozzle group configured to eject a second liquid to the cloth, and a wiping unit configured to wipe a nozzle surface on which the first nozzle group is disposed, wherein the first liquid is aqueous ink and the second liquid is a liquid including a softening agent, and the second nozzle group executes a softening treatment of ejecting the second liquid to the cloth, and a water repellent treatment of making the second liquid adhere to the nozzle surface.
