An anhydrous fiber-dyeing apparatus using vacuum transfer, includes: a hollow drum in which a plurality of fine holes are formed to penetrate therethrough, and a fiber to be dyed are wound around an outer surface thereof; a transfer film covering the outer surface of the fiber wound around the drum and having an inner side surface coated with a dye; heating means heating the fiber wound around the drum; and a vacuum means suctioning air through an inner space of the drum to form a vacuum pressure through the fine holes of the drum.

A color control method for four-color field jet dyeing is provided. The method includes: obtaining fabric parameters of a fabric to be dyed; obtaining a fabric sample color; ascertaining whether predetermined pre-color-development color parameters corresponding to the fabric parameters and the fabric sample color exist in a field jet dyeing database; if not, generating temporary pre-color-development color parameters based on the fabric parameters and the fabric sample color, taking the temporary pre-color-development color parameters as contrast sample parameters, and generating field jet dyeing parameters according to the contrast sample parameters to dye the fabric; and if yes, taking the predetermined pre-color-development color parameters in the field jet dyeing database as contrast sample parameters, and generating field jet dyeing parameters according to the contrast sample parameters to dye the fabric. A color control device and a color control system are further provided.

The machine (1) for the treatment of fabrics according to the invention comprises a treatment tank (3) arranged for containing the fabric or other material to be treated (TC) and a treatment liquid. The head losses that the treatment liquid undergoes along the different collecting ducts (37A, 37B) between the treatment tank (3) and the relative entry nozzle (370A, 370B) in the collector (39) mutually differ at most of 10% of the losses themselves. The head losses that the treatment liquid undergoes between each entry nozzle (370A, 370B) in the collector (39) and the entry (410) in the chamber (41) of the pump impeller differ at most of 10% between the various entry nozzles (370A, 370B). The level of liquid on the bottom of the tank (3) is more even, and it is thus possible to make the machine (30) work with very low bath levels.

A liquid application unit includes a supply member, a liquid application device, and an application controller. The supply member includes a cylindrical or columnar winding core around which a linear medium is wound. The liquid application device applies liquid to the linear medium unwound and fed from the supply member. The application controller adjusts a liquid application length of the liquid applied by the liquid application unit to the linear medium in a feed direction of the linear medium. The application controller adjusts the liquid application length in the feed direction of the linear medium in accordance with a winding thickness of a remaining amount of the linear medium from an outer peripheral surface of the winding core.

A circulation protection device is provided for a conveyor-driven fabric dyeing machine that includes a machine body having a front end in which a fabric circulation detection idler and a fabric movement sensor are mounted and a rear end in which a rear fabric guide and a fabric management device are mounted. Control is conducted with a computer program so that when the fabric circulation detection idler detects the fabric is not in movement, the conveyor is shut down; and when the fabric movement sensor detects the fabric is moving excessively fast or slow or gets jamming and stopped, the conveyor is controlled to automatically adjust the speed thereof or stops operation. When the fabric falls from a dyeing tube down to a conveyor, the rear fabric guide adjusts an entry angle of the fabric and the fabric management device allows the fabric to be orderly deposited on the conveyor.
