Abstract
A flame-retardant fiber composite includes an acrylic fiber A containing an acrylic copolymer and an aramid fiber. The acrylic fiber A is substantially free of an antimony compound, and the flame-retardant fiber composite forms a surface-foamed char layer when burned. A flame-retardant work clothing includes the flame-retardant acrylic fiber. A highly flame-retardant fiber composite and highly flame-retardant work clothing include an acrylic fiber, and are capable of exhibiting high flame retardancy while suppressing environmental impacts caused by a flame retardant.
