Disclosed is a method for producing an embroidery pattern through stitching to a substrate, particularly a method for producing a colored embroidery pattern having color disposition corresponding to a complex shape or stitches, simply and at low cost. The method includes: forming an embroidery base pattern to a substrate by use of single-color embroidery thread; printing a transfer image on an intermediate recording medium having a total light transmittance Tt of 60% or higher by use of a sublimable disperse dye, the transfer image being used for dyeing the embroidery thread of the embroidery base pattern; superposing the transfer image on the embroidery base pattern, while the intermediate recording medium is positioned from the backside of a printed surface of the recording medium; and heat-pressing the intermediate recording medium from the backside of the recording medium, to thereby dye the embroidery thread of the embroidery base pattern.

A textile printing method for printing on a fabric, the fabric being a nonwoven fabric containing synthetic fibers. includes a first adhering step of adhering to the fabric by ejecting a dyeing ink by an ink jet method, and a second adhering step of adhering a non-dyeing ink to the fabric. The dyeing ink contains a disperse dye, a water-soluble organic solvent, and water, and the non-dyeing ink contains a water-soluble organic solvent and water. The water-soluble organic solvent contained in the non-dyeing ink contains a glycol-based organic solvent having a HSP value of 13.6 or more, and the content of the glycol-based organic solvent is 80% by mass or more relative to the total amount of the organic solvent contained in the non-dyeing ink. The adhesion position of the dyeing ink and the adhesion position of the non-dyeing ink are at least partially overlapped each other.

The present disclosure provides a fluid set for printing on textile. The fluid set contains a pretreatment composition, and a mixture of a pigment and a disperse dye as the colorant. The blending of a pigment with a disperse dye as the colorant together with a suitable pretreatment composition provides better image quality.

The present invention relates to a waterless fiber dyeing method using a mixed fluid medium, in which supercritical carbon dioxide fluid medium is mixed with steam to form a mixed fluid medium, so that the waterless fiber dyeing effect to natural fibers is improved. The method of the invention can effectively modify the hydrophobic supercritical carbon dioxide fluid medium and improve the polarity thereof, thereby increasing the solubility of polar dye under the dyeing condition and simultaneously expanding the fiber. Thus, the present invention significantly improves the dyeability and dyeing behavior of the hydrophilic fibers in supercritical carbon dioxide fluids. The invention has the advantages of simple process, convenient operation and low energy consumption, and avoids consuming a large amount of water resources and discharging pollutants in the traditional process, and has the characteristics of environmentally friendly and high efficiency.
