Abstract

A dye produced from tobacco plant materials selected from tobacco plants are described and a process for making the dye from the tobacco plants. In a preferred embodiment, the tobacco plants are organically grown and the stems and leaves of the plants are utilized to produce the dye. In one embodiment, the process percolates a hot liquid solution onto the plant materials to produce tobacco plant fiber and the dye. In the preferred embodiment, the process includes the steps of grinding the plant materials, adding treated water to form a solution, adding plant enzymes, heating the solution for set periods of time and selectively adjusting the pH level of the solution. The dye can be produced in many colors and does not require a mordant to bind. The process does not produce waste. The process expands the use of tobacco plants, minimizes environmental impacts and requires less material, fuel and other resources.

Claims (25)

1. A process for producing a dye from a tobacco plant, said process comprising the steps of:

a) selecting one or more tobacco plant materials from said tobacco plant for processing into said dye;

b) grinding said tobacco plant materials;

c) adding water to said tobacco plant materials to produce a first solution and adjusting the pH to approximately 5.0;

d) adding a first enzyme cocktail comprising pectate lyase and xylanase to said first solution to produce a second solution;

e) heating said second solution and adjusting the pH to approximately 11.5;

f) adding a second enzyme cocktail comprising cellulase to said second solution to produce a third solution;

g) heating said third solution and adjusting pH to approximately 10.0;

h) cooling said third solution; and

i) adjusting a pH level of said third solution to a pH of approximately 2.0.

2. The process according to claim 1 , wherein said adjusting step is accomplished by interacting said third solution with one or more titanium plates.

3. The process according to claim 1 further comprising the step of blending said third solution in a blender.

4. The process according to claim 3 , wherein said adjusting step accomplished by interacting said third solution with titanium in or associated with said blender.

5. A process for producing a dye from a tobacco plant, said process comprising the steps of:

a) selecting one or more tobacco plant materials from said tobacco plant for processing into said dye;

b) grinding said tobacco plant materials;

c) adding water to said tobacco plant materials to produce a first solution and adjusting the pH to approximately 5.0;

d) adding a first enzyme cocktail comprising pectate lyase and xylanase to said first solution to produce a second solution;

e) heating said second solution and adjusting the pH to approximately 11.5;

f) adding a second enzyme cocktail comprising cellulase to said second solution to produce a third solution;

g) heating said third solution and adjusting the pH to approximately 10.0;

h) cooling said third solution;

i) transferring said third solution into a process vessel through a filter having one or more titanium plates;

j) blending said third solution with a blender having one or more titanium blades; and

k) adjusting a pH level of said third solution by interacting said third solution with said titanium plates and said titanium blades to a pH of approximately 2.0.
