Natural dyeing method of fiber using an indigo plant

Provided is a natural dyeing method of a fiber using an indigo plant. The natural dyeing method includes dissolving a water-soluble pigment present in leaves of the indigo plant in water to mix the water containing the water-soluble pigment with lime powder and air, concentrating the resulting mixture into an insoluble pigment, mixing the concentrated indigo plant dye with caustic soda to reduce the resulting mixture into a water-soluble pigment through microbial fermentation, immersing a fiber in the soluble indigo plant dye solution to dye the fiber, and bringing the dyed fiber into contact with air to convert the soluble indigo plant dye solution into the insoluble pigment again, thereby completing natural dyeing using the indigo plant. Therefore, the natural dyeing can be performed at a very fast dyeing rate, and the fiber can show excellent color fastness. Also, the fiber cannot be easily discolored by water or detergent, and can be useful in preventing water pollution or dermatitis.

Reactive inks and methods of generating an image on a substrate using both reactive and heat activated inks are presented. An image is printed on a substrate, without reacting the reagents in the ink. Subsequently, the reagents are reacted to fix the image to a substrate, with substantial permanency and fastness. Sublimation or similar heat activated dyes are printed are also printed on the substrate. The sublimation or similar heat activated dyes are activated, and have an affinity for polymer that is applied to the substrate.

Reactive ink printing process

Reactive dye and process of printing same

A method of printing an ink that comprises reactive dyes as colorants. The ink has at least one cyclodextrin (CD) compound to react with reactive dye molecules, while a hydrophobic cavity is filled with a disperse dye component to create an encapsulation prior to the ink formulation stage. The ink also includes a crosslinking agent that is capable of creating a chemical bonding reaction between the unreacted portion of the hydroxyl functional groups of cyclodextrin (CD), an optional alkaline substance, and other optional ink additives. Permanently bonded color images are provided by the reaction between the chemically altered and colored cyclodextrin (CD) and the final substrate, which may be any cellulosic, protein, or polyamide fiber material, or mixtures with polyester, by the application of energy.
