のが現状である。However, when meta-aramid fibers, which have excellent heat resistance and flame retardancy, are exposed to strong flames such as those from a burner, they shrink and cause pitting, reducing their protective properties. No effective method has been found to modify the polymer to suppress thermal shrinkage, which causes holes, and the current solution is to mix para-aramid fibers.

される。In the method of the present invention, as described above, a meta-aramid fiber fabric is flame-retardant treated with a dispersion containing a halogen-based flame retardant and a phosphorus-based flame retardant. A representative example of this is a halogen flame retardant whose main component is cyclododecane.
This is commercially available as a flame retardant for post-processing of polyester; for example, Pyrogard F-

-1 etc. can be mentioned. In addition, representative examples of phosphorus-based flame retardants include phosphorus-based flame retardants whose main component is dialkyl phosphonocarboxylic acid amide, and these are commercially available as durable flame retardants for cellulose fibers. For example, Ciba Geigy's Pyrobatex-CP and Meisei Chemical Industry Co., Ltd.'s Phoscon 82 can be mentioned. These flame retardant agents are applied to fibers using conventional resin processing equipment and conventional processing methods.

している。[Function] In the present invention, as a result of flame-retardant processing using a combination of halogen-based flame retardants and phosphorus-based flame retardants, even when the treated fabric is exposed to strong flames, it does not cause holes and has high protection properties. Although it is not clear whether this is the case, the present inventors speculate as follows. For meta-aramid fibers, which are originally carbonized, the carbonization promoting effect of the phosphorus-based flame retardant, which promotes carbonization, is accelerated by the halogen-based flame retardant, which is generally said to promote melting, and a carbonized layer is formed before the fibers undergo thermal contraction. It is assumed that this will reduce the amount of hole space.
