Abstract

Flame resistant fiber, fabric, including woven, knit, and non-woven fabrics, and clothing incorporating such fibers are provided that include a blend of inherently flame resistant fiber, non-flame resistant fiber, and/or treated flame resistant fiber.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A flame resistant fabric comprising:
 a modacrylic fiber;   a fiber embedded with activated particles; and   an aramid fiber.   
     
     
         2 . The flame resistant fabric of  claim 1 , wherein the flame resistant fabric passes the National Fire Protection Association 2112 standards. 
     
     
         3 . The flame resistant fabric of  claim 1 , including:
 about 30% to about 75% of the modacrylic fiber;   about 10% to about 70% of the fiber embedded with active particles; and   about 5% to about 50% of the aramid fiber.   
     
     
         4 . The flame resistant fabric of  claim 1 , further comprising a cellulosic fiber. 
     
     
         5 . The flame resistant fabric of  claim 4 , wherein the cellulosic fiber comprises cotton. 
     
     
         6 . The flame resistant fabric of  claim 4 , wherein the cellulosic fiber comprises rayon. 
     
     
         7 . The flame resistant fabric of  claim 4 , wherein the cellulosic fiber comprises lyocell. 
     
     
         8 . The flame resistant fabric of  claim 4 , including:
 about 30% to about 75% of the modacrylic fiber;   about 10% to about 70% of the fiber embedded with active particles;   about 5% to about 50% of the aramid fiber; and   about 10% to about 40% of the cellulosic fiber.   
     
     
         9 . The flame resistant fabric of  claim 4 , including:
 about 45% of the modacrylic fiber;   about 20% of the fiber embedded with active particles;   about 15% aramid fiber.   about 20% of the cellulosic fiber, wherein the cellulosic fiber comprises cotton.   
     
     
         10 . The flame resistant fabric of  claim 4 , including:
 about 50% of the modacrylic fiber;   about 20% of the fiber embedded with active particles;   about 15% aramid fiber.   about 50% of the cellulosic fiber, wherein the cellulosic fiber comprises cotton.   
     
     
         11 . The flame resistant fabric of  claim 4 , including:
 about 40% of the modacrylic fiber;   about 20% of the fiber embedded with active particles;   about 20% aramid fiber.   about 20% of the cellulosic fiber, wherein the cellulosic fiber comprises cotton.   
     
     
         12 . The flame resistant fabric of  claim 4 , including:
 about 30% of the modacrylic fiber;   about 20% of the fiber embedded with active particles;   about 20% aramid fiber.   about 30% of the cellulosic fiber, wherein the cellulosic fiber comprises flame resistant rayon.   
     
     
         13 . The flame resistant fabric of  claim 4 , including:
 about 35% of the modacrylic fiber;   about 20% of the fiber embedded with active particles;   about 15% aramid fiber.   about 30% of the cellulosic fiber, wherein the cellulosic fiber comprises flame resistant rayon.   
     
     
         14 . The flame resistant fabric of  claim 4 , including:
 about 30% of the modacrylic fiber;   about 20% of the fiber embedded with active particles;   about 15% aramid fiber;   about 35% of the cellulosic fiber, wherein the cellulosic fiber comprises flame resistant rayon.   
     
     
         15 . The flame resistant fabric of  claim 4 , including:
 about 40% of the modacrylic fiber;   about 20% of the fiber embedded with active particles;   about 20% aramid fiber.   about 20% of the cellulosic fiber, wherein the cellulosic fiber comprises flame-resistant rayon.   
     
     
         16 . The flame resistant fabric of  claim 4 , including:
 about 40% of the modacrylic fiber;   about 20% of the fiber embedded with active particles;   about 20% aramid fiber.   about 20% of the cellulosic fiber, wherein the cellulosic fiber comprises lyocell.   
     
     
         17 . The flame resistant fabric of  claim 1 , wherein the activated particles include a member selected from a group consisting of: activated carbon derived from coconut, volcanic sand or rock, and combinations thereof. 
     
     
         18 . The flame resistant fabric of  claim 1 , wherein the fiber embedded with activated particles comprises a member selected from a group consisting of: nylon, polyester, aramid, cellulose, modacrylic, polybenzimidazole (PBI), and/or poly(p-phenylene-2,6-benzobisoxazole) (PBO), and combinations thereof. 
     
     
         19 . A roll of the flame resistant fabric of  claim 1 . 
     
     
         20 . An article of clothing comprising the flame resistant fabric of  claim 1 .
