Synthetic leather

Abstract

Provided is a synthetic leather including: a base fabric that has a limiting oxygen index of 25 or more, and that is a knitted body of a yarn including a flame-retardant fiber having a limiting oxygen index of 25 or more, a cellulose-based fiber, and a carbon fiber; an adhesion layer containing a flame retardant, the adhesion layer being provided at at least one side of the base fabric; and a skin layer provided at a side of the adhesion layer opposite from a side at which the base fabric is provided.

1 . A synthetic leather comprising:
 a base fabric that has a limiting oxygen index of 25 or more, and that is a knitted body of at least one yarn, each yarn comprising at least one of a flame-retardant fiber having a limiting oxygen index of 25 or more, a cellulose-based fiber, or a carbon fiber, and the base fabric includes the flame retardant fiber, the cellulose-based fiber, and the carbon fiber;   an adhesion layer containing a flame retardant, the adhesion layer being provided at at least one side of the base fabric; and   a skin layer provided at a side of the adhesion layer opposite from a side at which the base fabric is provided.   
     
     
         2 . The synthetic leather according to  claim 1 , wherein the flame-retardant fiber comprises one or more selected from the group consisting of an aramid fiber, a meta-aramid fiber, a polyphenylene sulfide fiber, an acrylic fiber, a vinyl chloride fiber, a polyclar fiber, a vinylidene chloride fiber, an acrylic-vinyl chloride copolymer fiber, an acrylic-vinylidene chloride copolymer fiber, and an a polybenzimidazole fiber. 
     
     
         3 . The synthetic leather according to  claim 1 , wherein the carbon fiber comprises one or more selected from the group consisting of a polyacrylonitrile-based fiber, a pitch-based fiber, and a phenolic fiber. 
     
     
         4 . The synthetic leather according to  claim 1 , wherein:
 a content of the carbon fiber is from 20% by mass to 40% by mass with respect to a total mass of the yarn constituting the knitted body,   a content of the cellulose-based fiber is from 25% by mass to 45% by mass with respect to the total mass of the yarn constituting the knitted body, and   a total content of the flame-retardant fiber and the carbon fiber is greater than the content of the cellulose-based fiber.   
     
     
         5 . The synthetic leather according to  claim 1 , further including an intermediate layer between the adhesion layer and the skin layer. 
     
     
         6 . The synthetic leather according to  claim 5 , wherein the intermediate layer comprises a flame retardant.
