Abstract
The subject invention provides environmentally-friendly compositions and methods for enhancing the printing and dyeing of goods such as paper and textiles. In certain embodiments, the methods of the subject invention comprise incorporating the application of a biological amphiphilic molecule into a printing or dyeing process to reduce chemical usage, reduce water usage, reduce water pollution and/or provide an added benefit to the process. In certain embodiments, the methods of the subject invention comprise substituting a chemical surfactant with a biological amphiphilic molecule in one or more steps involved in printing and/or dyeing that would traditionally utilize a chemical surfactant.
Claims26
A method for printing and/or dyeing a surface, the method comprising applying a biological amphiphilic molecule and a colorant to the surface, wherein the biological amphiphilic molecule serves as an adjuvant, an additive and/or an active ingredient involved in delivery and fixing of the colorant to the surface.
An ink composition comprising a biological amphiphilic molecule, a colorant and a carrier, wherein the colorant is a pigment or a dye, and wherein the carrier is water or a solvent.
A textile good comprising yarn, thread, fabric, cloth, or a finished product produced from yard, thread, fabric, and/or cloth, wherein the yarn, thread, fabric, cloth is impregnated with, printing with and/or coated with a biological amphiphilic molecule and a colorant.
A paper good comprising lignocellulosic fibers, or a finished product produced from lignocellulosic fibers, wherein the fiber is impregnated with, printed with and/or coated with a biological amphiphilic molecule and a colorant.
A method for de-inking a surface, the method comprising applying a biological amphiphilic molecule the surface such that the biological amphophilic molecule contacts the ink, allowing the ink to separate from the surface, and collecting the ink.
