Protein polyurethane alloy materials

Abstract

Materials comprising a protein polyurethane alloy comprising one or more proteins dissolved within one or more polyurethanes. The materials can be subjected to various leather and/or textile treatments to create described properties. For example, in some embodiments, the material can be dyed. As another example, in some embodiments, the material can be fatliquored.

What is claimed is: 
     
         1 . A material, comprising:
 a textile;   a protein polyurethane alloy disposed over the textile, the protein polyurethane alloy comprising a protein dissolved within a polyurethane; and   about 1 wt % to about 16 wt % of one or more fatliquors.   
     
     
         2 . The material of  claim 1 , wherein the protein polyurethane alloy comprises greater than 50 wt % of the protein. 
     
     
         3 . The material of  claim 1 , wherein the protein polyurethane alloy comprises about 60 wt % to about 90 wt % of the protein. 
     
     
         4 . The material of any one of  claims 1-3 , wherein the one or more fatliquors comprise a functionalized oil. 
     
     
         5 . The material of any one of  claims 1-3 , wherein the one or more fatliquors are selected from the group consisting of: a sulfited fatliquor, a sulfated fatliquor, or a combination thereof. 
     
     
         6 . The material of any one of  claims 1-5 , wherein the material has a modulus of elasticity of 9*10{circumflex over ( )}7 Pa or less. 
     
     
         7 . The material of any one of  claims 1-5 , wherein the material has a modulus of elasticity of 6*10{circumflex over ( )}7 Pa or less. 
     
     
         8 . A material, comprising:
 a textile;   a protein polyurethane alloy comprising a protein dissolved within a polyurethane;   a first portion having a first protein polyurethane alloy density; and   a second portion having a second protein polyurethane alloy density different from the first protein polyurethane alloy density.   
     
     
         9 . The material of  claim 8 , wherein the first protein polyurethane alloy density is less than or greater than the second protein polyurethane alloy density by 5% or more. 
     
     
         10 . The material of  claim 8 or claim 9 , wherein the first portion comprises a first protein polyurethane alloy layer and wherein the second portion comprises a second a protein polyurethane alloy layer. 
     
     
         11 . The material of  claim 10 , wherein:
 the textile comprises a top surface and a bottom surface,   the first protein polyurethane alloy layer is disposed over the top surface of the textile, and   the second protein polyurethane alloy layer is disposed over the bottom surface of the textile.   
     
     
         12 . The material of  claim 8 or claim 9 , wherein:
 the first portion comprises the protein polyurethane alloy integrated into the textile at the first protein polyurethane alloy density, and   the second portion comprises the protein polyurethane alloy integrated into the textile at the second protein polyurethane alloy density.   
     
     
         13 . The material of  claim 8 or claim 9 , wherein
 the textile comprises a first textile layer coupled to a second textile layer,   the first portion comprises the protein polyurethane alloy integrated into the first textile layer at the first protein polyurethane alloy density, and   the second portion comprises the protein polyurethane alloy integrated into the second textile layer at the second protein polyurethane alloy density.   
     
     
         14 . The material of any one of  claims 8-13 , further comprising a cross-linker selected from the group consisting of: an epoxy-based cross-linker, an isocyanate-based cross-linker, and a carbodiimide-based cross-linker. 
     
     
         15 . The material of  claim 14 , wherein the cross-linker is a carbodiimide-based cross-linker. 
     
     
         16 . An aqueous formulation, comprising:
 water;   an aqueous polyurethane dispersion;   a protein;   about 4 wt % to about 10 wt % of one or more colored dyes; and   a foam stabilizer.   
     
     
         17 . The formulation of  claim 16 , wherein the protein is dissolved within the polyurethane of the polyurethane dispersion. 
     
     
         18 . A material, comprising:
 a textile;   a protein polyurethane alloy integrated into the textile, the protein polyurethane alloy comprising a protein dissolved within a polyurethane; and   about 100 wt % to about 250 wt % of one or more colored dyes, the wt % of the one or more colored dyes measured relative to the weight of the protein in the protein polyurethane alloy.
