Claims

exact text as granted — not AI-modified
1 .- 109 . (canceled) 
     
     
         110 . A yarn comprising fibers and a water dispersible rosin ester or a derivative thereof. 
     
     
         111 . The yarn of  claim 110 , wherein the yarn comprises a spun yarn. 
     
     
         112 . The yarn of  claim 110 , wherein the yarn comprises fibers and the water dispersible rosin ester. 
     
     
         113 . The yarn of  claim 110 , wherein the yarn comprises fibers and the derivative of the water dispersible rosin ester. 
     
     
         114 . The yarn of  claim 110 , wherein the water dispersible rosin ester is a neutralized water dispersible rosin ester. 
     
     
         115 . The yarn of  claim 110 , wherein the fibers were treated with the water dispersible rosin ester or the derivative thereof. 
     
     
         116 . The yarn of  claim 110 , wherein the fibers comprise cotton, wool, rayon, polyester, nylon, cellulose, ramie, flax, polyacrylic ester, polyvinyl alcohol, polyacrylonitrile, or combinations and blends thereof. 
     
     
         117 . A fabric comprising the yarn of  claim 110 . 
     
     
         118 . A fiber, wherein the fiber is suitable to be used in a yarn, and wherein the fiber has been treated with a water dispersible rosin ester or a derivative thereof. 
     
     
         119 . The fiber of  claim 118 , wherein the fiber has been treated with the water dispersible rosin ester. 
     
     
         120 . The fiber of  claim 118 , wherein the fiber has been treated with the derivative of the water dispersible rosin ester. 
     
     
         121 . The fiber of  claim 118 , wherein the fiber comprises cotton, wool, rayon, polyester, nylon, cellulose, ramie, flax, polyacrylic ester, polyvinyl alcohol, polyacrylonitrile, or combinations and blends thereof. 
     
     
         122 . The fiber of  claim 118 , wherein the water dispersible rosin ester is a neutralized water dispersible rosin ester.
