Flame-Retardant Bedding

Abstract

The object of the present invention is to provide a bedding in which polyester having excellent elasticity is used for a batting therein, and which is provided with high-grade flame retardance so as to withstand long-time flaming, even though only a small amount of a halogen-containing fiber is used therein. By configuring the flame-retardant bedding product so that it is composed of a batting and a ticking for covering the batting and that the batting comprises a cellulose fiber (A), a polyester fiber (B), and a halogen-containing fiber (C) as essential components, the bedding product is caused to achieve the above-described object. In addition to the excellent flame retardance, the bedding product of the present invention is allowed to have excellent cushiony properties, since a large amount of a polyester fiber can be used therein because the amount of a halogen-containing fiber used therein is relatively small. Further, with the present invention, even a flame-retardant bedding product in which an easily inflammable fiber such as a polyester fiber or a cellulose fiber is used for a ticking exhibits sufficient flame retardance. Therefore, it is possible to provide a bedding that exhibits excellent feeling and touch as well as flame retardance.

1 . A flame-retardant bedding product comprising a batting and a ticking for covering the batting, wherein
 the batting is formed of fibers comprising 10 wt % to 40 wt % of a cellulose fiber (A), 50 wt % to 80 wt % of a polyester fiber (B), and 10 wt % to 40 wt % of a halogen-containing fiber (C).   
   
   
       2 . The flame-retardant bedding product according to  claim 1 , wherein the cellulose fiber (A) is at least one fiber selected from the group consisting of cotton, hemp, rayon, polynosic, cuprammonium rayon, acetate, and triacetate. 
   
   
       3 . The flame-retardant bedding product according to  claim 1 , wherein the cellulose fiber (A) is a rayon fiber containing 20 wt % to 50 wt % of a flame retardant selected from silicic acid and aluminum silicate. 
   
   
       4 . The flame-retardant bedding product according to  claim 1 , wherein the cellulose fiber (A) is a fiber obtained by adding a flame retardant to a cellulose fiber so that the content of the flame retardant is 6 wt % to 25 wt %, the flame retardant being at least one selected from the group consisting of phosphoric acid ester compounds, halogen-containing phosphoric acid ester compounds, condensed phosphoric acid ester compounds, polyphosphate compounds, red phosphorus, amine compounds, boric acid, halogen compounds such as bromides, urea-formaldehyde compounds, and ammonium sulfate. 
   
   
       5 . The flame-retardant bedding product according to  claim 1 , wherein the polyester fiber (B) is at least one fiber selected from the group consisting of a polyester fiber having a melting point above 200° C., a low-melting-point binder fiber, and a flame-retardant polyester fiber. 
   
   
       6 . The flame-retardant bedding product according to  claim 5 , wherein the low-melting-point binder fiber is at least one fiber selected from the group consisting of a fiber made of a single component of a low-melting-point polyester, a fiber made of a composite of a polyester having a melting point above 200° C. and a low-melting-point polyester, and a fiber made of a composite of a polyester having a melting point above 200° C. and a low-melting-point polyolefin. 
   
   
       7 . The flame-retardant bedding product according to  claim 5 , wherein the flame-retardant polyester fiber is a fiber to which a flame retardant has been added, the flame retardant being at least one selected from the group consisting of phosphorus compounds, phosphoric acid ester compounds, halogen-containing phosphoric acid ester compounds, condensed phosphoric acid ester compounds, polyphosphate compounds, phosphazene compounds, red phosphorus, amine compounds such as hindered amine compounds, boric acid, halogen compounds such as bromides, urea-formaldehyde compounds, ammonium sulfate, hydrated metal compounds, metal oxides, organic metal compounds, and silicone compounds. 
   
   
       8 . The flame-retardant bedding product according to  claim 1 , wherein the halogen-containing fiber (C) is a modacrylic fiber. 
   
   
       9 . The flame-retardant bedding product according to  claim 1 , wherein the ticking contains a cellulose fiber and/or a polyester fiber. 
   
   
       10 . The flame-retardant bedding product according to  claim 9 , wherein the ticking is formed of 20 wt % to 80 wt % of a cellulose fiber, and 80 wt % to 20 wt % of a polyester fiber.
