FIREPROOF FABRIC AND FIREPROOF CLOTHING INCLUDING SAME
A fabric for fireproof clothing of the present invention is a fireproof fabric including flame-retardant fibers. The fabric is a woven fabric, a knitted fabric or a nonwoven fabric including 70 to 100 mass % of a polyetherimide fiber and 0 to 30 mass % of another flame-retardant fiber. The flame resistance, the heat resistance, and the wash resistance under ISO 11613-1999 as the international performance standards for fireproof clothing are: (1) flame resistance to be free from hole formation, dripping and melting; and to have afterflame time and afterglow time of not more than 2 seconds; (2) heat resistance to be free from firing, separation, dripping and melting; and to have a shrinkage rate of not more than 5%; and (3) washing resistance to have a shrinkage rate of not more than 3%. The fireproof clothing of the present invention includes the fireproof fabric fabricated as an inner liner. Thereby, the present invention provides a fabric for fireproof clothing that has excellent light resistance and heat resistance, and preferable dye-affinity and that can be produced at low cost, and fireproof clothing using the fabric.
1 . A fireproof fabric comprising a flame-retardant fiber,
