Described herein are methods of dyeing fibers, and dyed fibers and textiles made using the methods. The methods involve contacting a fiber with a dye liquor at a dye liquor temperature of about 30 C. to 115 C. to form a dyed fiber, wherein the dye liquor components include at least N,N-diacetyl indigo and a salt solution having ionic strength of about 0.03 M (moles/liter) to 1 M and pH of about 3 to 8 at 20 C. The contacting is generally carried out for a contact period of about 10 seconds to 30 minutes, for example by immersing the fiber in the heated dye liquor. By using the disclosed methods, N,N-diacetyl indigo is substantially uniformly distributed on the dyed fiber to provide intense, vibrant colors affixed thereto. Dyed textiles display substantially uniform color.

Anhydrous dyeing method for textile, including the steps of: using a pure dye as a plating material and a textile fabric as a substrate, and depositing the dye onto a surface of the textile fabric by using a physical vapor deposition technique. The color of plated textile fabric is fixed through steaming, heat setting or other post-processing methods. The invention achieves the purpose of dyeing textile fabric by depositing dye onto the surface of the textile fabric uniformly and densely using a physical vapor deposition technology, and fixing the color in a finishing step. The process is simple and convenient, produces no waste water discharge, has a high utilization rate of dye, and is operable and feasible for mass production.

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.
