[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anhydrous (waterless) yarn dyeing method and apparatus.

[0002]

2. Description of the Related Art Conventionally, yarn dyeing (yarn dyeing) involves immersing and dyeing yarns such as yarn, skein yarn, and cheese winding yarn in a dye filled in a dyeing kettle or a dyeing tank. A method of passing through a finishing step is generally used. Therefore, the workplace environment, for example,
It has been pointed out that the workplace is hot, humid in summer, odorous and dirty. Problems have also been pointed out in terms of worker health management, secondary pollution due to used wastewater, and shortened delivery times.

[0003] In the dyeing of fabrics having the same problems as the yarn dyeing, there are the following prior art documents as a solution. (1) In the copy dyeing method of Japanese Patent Application Laid-Open No. 2-200880, the gist is a scanner process consisting of an optoelectronic system that performs image processing such as color separation, color synthesis, etc., by sensing the design of the original image and converting it to an electric signal, A colorant corresponding to the pattern is electrostatically attracted to an electrostatic drum to develop the pattern, and the developed pattern is electrostatically transferred to a fabric to be dyed. From the printer process for fixing the transferred pattern, In the copy dyeing method, the fabric to be dyed is attached to the mount with a peelable adhesive and sent.
This is a copying and dyeing method in which the design is transferred to the cloth to be dyed and then the mount is peeled off from the cloth to be dyed, and has a feature that the design can be fixed by electrostatic transfer. (2) The processing agent and printing method for an electrophotographic printing cloth disclosed in JP-A-5-33274, the gist of which is that printing is performed by directly transferring and fixing a colored polyamide toner onto a cloth or the like by an electrostatic electrophotographic method. This is a printing method in which cloth is treated with a treatment agent containing a silicone resin emulsion.Since small-scale processing of various types can be delivered in a short period of time after receiving an order, there is no need for defective stocks, and effective use of funds is achieved. Water and heat energy can be omitted extremely and there is no concern about environmental pollution. (3) Japanese Patent Application Laid-Open No. 8-218279 discloses an inkjet printing fabric and a printing method and printed matter, the gist of which is inkjet printing with an ink containing an ionic dye, a nonionic surfactant and a dye to be used. A structure in which an ink containing an ionic dye is dyed on a fabric to which a polymer material having the opposite ionicity and an appropriate stiffening agent is applied by using inkjet printing, and a clear image can be dyed. It is characterized by eliminating waste of dye and exhibiting a color fixing effect.
