Abstract
Dyed materials comprising a textile with natural fibers comprising hydroxyl functional groups, a protein, a dye, and a cross-linker. The protein can be covalently linked to at least the natural fibers via the cross-linker. The dye can be bonded to the natural fibers, the cross-linker, the protein, or a combination thereof. The textiles can be dyed using an aqueous dyeing formulation comprising one or more proteins, one or more cross-linkers, and one or more dyes.
Claims85
A dyed material, comprising:
- a. a textile comprising natural fibers comprising hydroxyl functional groups;
- b. a protein;
- and
- c. a dye;
- wherein the protein is covalently linked to the natural fibers via one or more cross-linkers;
- and
- wherein the dye is bonded to the natural fibers, the one or more cross-linkers, the protein, or a combination thereof.
A textile dyeing formulation, comprising:
- water;
- one or more proteins;
- one or more cross-linkers, the one or more cross-linkers present at total weight percent ranging from greater than or equal to about 5 wt % to less than or equal to about 90 wt % relative to the one or more proteins in the formulation;
- and
- one or more dyes, the one or more dyes present at a total weight percent ranging from greater than or equal to about 5 wt % to less than or equal to about 200 wt % relative to the one or more proteins in the formulation.
A method for dyeing a textile, the method comprising:
- a. applying a protein formulation to a textile, wherein the protein formulation comprises water, one or more proteins, and one or more cross-linkers present at total weight percent ranging from greater than or equal to about 5 wt % to less than or equal to 90 about wt % relative to the one or more proteins in the formulation, and wherein the textile comprises natural fibers comprising hydroxyl functional groups;
- b. drying the protein formulation on the textile to form a cross-linked textile;
- and
- c. applying one or more dyes to the cross-linked textile to bond the one or more dyes to the natural fibers, the one or more cross-linkers, the one or more proteins, or a combination thereof.
A composite material, comprising:
- a. a composite textile comprising:
- i. a first fiber comprising hydroxyl functional groups, and
- ii. a second fiber comprising a synthetic polymer;
- b. a protein;
- and
- c. a dye;
- wherein
- the protein is covalently linked to at least the first fiber via an epoxy cross-linker;
- and
- wherein the dye is bonded to the first fiber, the epoxy cross-linker, the protein, or a combination thereof.
A textile dyeing formulation, comprising:
- water;
- one or more proteins;
- one or more epoxy cross-linkers, the one or more epoxy cross-linkers present at a total weight percent ranging from greater than or equal to about 10 wt % to less than or equal to about 90 wt % relative to the one or more proteins in the formulation;
- and
- one or more dyes, the one or more dyes present at a total weight percent ranging from greater than or equal to about 5 wt % to less than or equal to about 200 wt % relative to the one or more proteins in the formulation.
A method for dyeing a textile, the method comprising:
- a. applying a protein formulation to a composite textile, wherein the protein formulation comprises water, one or more proteins, and one or more epoxy cross-linkers present at a total weight percent ranging from greater than or equal to about 10 wt % to less than or equal to about 90 wt % relative to the one or more proteins in the formulation, and wherein the composite textile comprises a first fiber comprising hydroxyl functional groups and a second fiber comprising a synthetic polymer;
- b. drying the protein formulation on the composite textile to form a cross-linked textile;
- and
- c. applying one or more dyes to the cross-linked textile to bond the one or more dyes to the first fiber, the one or more epoxy cross-linkers, the one or more proteins, or a combination thereof.
