Suede-tone flame-retardant union cloth

Abstract

The present invention provides, at a low cost, a suede-like flame-retardant union fabric which exhibits excellent design and texture, which is comfortable, and which has high flame retardance. The suede-like flame-retardant union fabric is formed of warps and wefts, in which the warps are raised on at least one face of the fabric. In the suede-like flame-retardant union fabric, the warps include a polyester-based yarn, and the wefts include a spun yarn (A) that contains at least 70 wt % of a cellulosic fiber and a spun yarn (B) that contains a flame retardant-containing halogen-containing fiber containing 3 to 50 weight parts of a flame retardant with respect to 100 weight parts of halogen-containing fibers. The spun yarn (A) and the spun yarn (B) used as the wefts are alternately interweaved.
