Fire retardant mattress core covering

Abstract

The present invention, in embodiments, is a fitted mattress core covering having a non-woven fabric comprising a plurality of flame-retardant fibers and elastic piping located along an edge of the non-woven fabric. The non-woven fabric, in embodiments, is substantially free of fiberglass, and the fitted mattress core covering is configured to fit over a mattress core such that the elastic piping extends underneath the mattress core when the fitted mattress core covering fits over the mattress core.

         6 . The fitted mattress core covering of  claim 1 , wherein the flame-retardant fibers are present in 100% of the non-woven fabric. 
     
     
         7 . The fitted mattress core covering of  claim 6 , wherein the density of the flame-retardant fibers is 1.5 denier to 7 denier. 
     
     
         8 . The fitted mattress core covering of  claim 6 , wherein the weight of the flame-retardant fibers in the non-woven fabric is 2 ounces per square yard to 12 ounces per square yard. 
     
     
         9 . The fitted mattress core covering of  claim 1 , wherein the weight of the non-woven fabric is 50 grams per square meter to 300 grams per square meter. 
     
     
         10 . The fitted mattress core covering of  claim 9 , wherein the weight of the non-woven fabric is 100 grams per square meter to 200 grams per square meter. 
     
     
         11 . The fitted mattress core covering of  claim 1 , further comprising a coating;
 wherein the coating comprises at least one of nanoclay or graphite.   
     
     
         12 . A fitted mattress core covering comprising:
 (i) a non-woven fabric comprising a plurality of flame-retardant fibers and a plurality of non-flame retardant fibers;
 wherein the non-woven fabric is substantially free of fiberglass; and 
   (ii) elastic piping located along an edge of the non-woven fabric;   
       wherein the fitted mattress core covering is configured to fit over a mattress core such that the elastic piping extends underneath the mattress core when the fitted mattress core covering fits over the mattress core. 
     
     
         13 . The fitted mattress core covering of  claim 12 , wherein the flame-retardant fibers comprise at least one of cellulosic fiber incorporated with silica, cellulosic fiber incorporated with at least one flame-retardant chemical, polyaramids, elastanes, or polyesters. 
     
     
         14 . The fitted mattress core covering of  claim 12 , wherein the flame-retardant fibers comprise at least one of polyurethanes or elastanes. 
     
     
         15 . The fitted mattress core covering of  claim 12 , wherein the non-flame retardant fibers comprise at least one of cotton, bamboo, wool, cashmere, or silk. 
     
     
         16 . The fitted mattress core covering of  claim 12 , wherein the flame retardant fibers comprise 0.1% to 30% of polaramid fibers, based on a total weight of the flame retardant fibers and the non-flame retardant fibers. 
     
     
         17 . The fitted mattress core covering of  claim 12 , wherein the non-woven fabric is substantially free of thermoplastic and latex. 
     
     
         18 . A fitted mattress core covering comprising:
 (i) a stitch-bonded non-woven fabric comprising a plurality of flame-retardant fibers;
 wherein the stitch-bonded non-woven fabric is substantially free of fiberglass; and 
   (ii) elastic piping located along an edge of the stitch-bonded non-woven fabric;   
       wherein the fitted mattress core covering is configured to fit over a mattress core such that the elastic piping extends underneath the mattress core when the fitted mattress core covering fits over the mattress core. 
     
     
         19 . The fitted mattress core covering of  claim 18 , wherein the weight of the stitch-bonded non-woven fabric is 50 grams per square meter to 300 grams per square meter.
