Abstract
One or more embodiments of the present invention relate to a flame-retardant fabric containing a modacrylic fiber in an amount of 30 to 60 mass %, a cellulose fiber in an amount of 20 to 50 mass %, and an aramid fiber in an amount of 10 to 20 mass %. The flame-retardant fabric includes a compound containing stannate and zinc in an amount of 1.4 to 5.0 mass % with respect to a total mass of the flame-retardant fabric. The flame-retardant fabric with improved flame retardancy by suppressing the decrease in tear strength of the fabric after combustion and a work clothing including the flame-retardant fabric are provided.
Claims20
A flame-retardant fabric comprising:
- a modacrylic fiber in an amount of 30 to 60 mass %, a cellulose fiber in an amount of 20 to 50 mass %, and an aramid fiber in an amount of 10 to 20 mass %,
- wherein:
- the flame-retardant fabric comprises a compound containing stannate and zinc in an amount of 1.6 to 3.56 mass % with respect to a total mass of the flame-retardant fabric,
- the compound containing stannate and zinc comprises one or more selected from the group consisting of zinc hydroxystannate and zinc stannate,
- the flame-retardant fabric comprises substantially no antimony compound, and
- a char length of the flame-retardant fabric measured by a flammability test based on ASTM D6413 is 71 mm or less.
