Abstract

A yarn, fabric, or garment that includes a plurality of fibers or a fiber-based material. The yarn, fabric, or garment includes lignin as a primary dye agent. Lignin may be present in the plurality of fibers or the fiber-based material in a range of 0.3 percent to 10 percent by weight.

What is claimed: 
     
         1 . A yarn comprising:
 a plurality of fibers comprising lignin as a primary dye agent.   
     
     
         2 . A textile fabric comprising:
 a plurality of yarns according to  claim 1 .   
     
     
         3 . A garment comprising:
 a plurality of yarns according to  claim 1 .   
     
     
         4 . The yarn according to  claim 1 , wherein the plurality of fibers comprise lignin in a range of 0.3 percent to 10 percent by weight. 
     
     
         5 . The yarn according to  claim 1 , wherein the plurality of fibers comprise lignin in a range of 0.3 percent to 5 percent by weight. 
     
     
         6 . The yarn according to  claim 1 , wherein the plurality of fibers include at least 30 percent cellulosic fibers. 
     
     
         7 . The yarn according to  claim 1 , wherein the plurality of fibers comprise at least 30 percent cellulosic fibers. 
     
     
         8 . The yarn according to  claim 1 , wherein the plurality of fibers are bacteriostatic. 
     
     
         9 . A textile fabric comprising:
 a fiber-based material including lignin as a primary dye agent.   
     
     
         10 . The fabric according to  claim 9 , wherein the fiber-based material includes lignin in a range from 0.3 percent to 10 percent by weight. 
     
     
         11 . The fabric according to  claim 9 , wherein the fiber-based material includes lignin in a range from 0.3 percent to 5 percent by weight. 
     
     
         12 . The fabric according to  claim 9 , wherein the fiber-based material comprises at least 30% cellulosic fibers. 
     
     
         13 . The fabric according to  claim 9 , wherein the fiber-based material is bacteriostatic. 
     
     
         14 . The fabric according to  claim 9 , wherein the fiber-based material comprises a first fiber-based yarn and a second fiber-based yarn, the first fiber-based yarn including lignin as a primary dye agent, the first fiber-based yarn is a warp yarn or a weft yarn and the second fiber-based yarn is the other of a warp yarn or a weft yarn, the first fiber-based yarn and the second fiber based yarn woven in a twill pattern. 
     
     
         15 . The fabric according to  claim 14 , wherein the second fiber-based yarn comprises lignin as a primary dye agent. 
     
     
         16 . A brown colored garment comprising:
 a fiber-based material including lignin as a primary dye agent.   
     
     
         17 . The garment according to  claim 16 , wherein the fiber-based material comprises lignin in a range of 0.3 percent to 10 percent by weight. 
     
     
         18 . The garment according to  claim 16 , wherein the fiber-based material comprises lignin in a range of 0.3 percent to 5 percent by weight. 
     
     
         19 . The garment according to  claim 16 , wherein the fiber-based material is at least 30 percent cellulosic fibers. 
     
     
         20 . The garment according to  claim 16 , wherein the fiber-based material comprises a first fiber-based yarn and a second yarn, the first fiber-based yarn comprises lignin as a primary dye agent.
