対する難燃化の研究は数が少ない。[0003] Conventionally, research on flame retardancy of fibers has been conducted mainly on single fibers of specific fibers such as polyester fibers and viscose rayon fibers, mainly on modacrylic fibers and polychloral fibers. Some of the fibers alone have excellent flame retardancy, but at present, they have hardly responded to the increasingly diverse and sophisticated demands of consumers. Therefore, blending, blending, weaving, and the like of the flame-retardant fiber and other fibers are inevitably required. However, there are few studies on flame-retardation of a composite in which two or more different kinds of fibers are mixed.

When the total content of the Sb compound and the specific hydroxide is less than 6%, in order to obtain the required flame retardancy as a flame retardant fiber composite, the mixing ratio of the halogen flame retardant-containing fiber in the composite is reduced. It needs to be raised. When the mixing ratio of the halogen-containing flame retardant-containing fiber is increased as described above, other than the flame retardancy of the flame-retardant fiber composite, for example,
It becomes difficult to obtain performance such as feeling, moisture absorption, washing resistance, and durability. On the other hand, if the total content exceeds 50%,

水酸化物の使用により解消されるためである。The reason why the flame-retardant fiber composite of the present invention has excellent flame retardancy is that the halogen-containing flame retardant-containing fiber contains a large amount of an Sb compound which produces a gas-type flame retardant effect. In addition to generating gases such as hydrogen halide, halogen, and antimony halide at relatively low temperatures, the incombustible decomposition products cover flammable fibers, and the following disadvantages when only Sb compounds are used Is solved by using a specific hydroxide.

があることである。実用的燃焼試験などにおいて、残燼
といわれている現象である。The disadvantage of using only the above-mentioned Sb compound is that the reaction of the Sb compound and the generation of non-flammable gas occur at a relatively low temperature, so that some flammable components remain and the high-temperature flame If it is exposed, it may not extinguish the fire completely and may burn flamelessly. It is a phenomenon called afterglow in practical combustion tests.

と推察される。In the present invention, by using a specific hydroxide in combination with the Sb compound, this problem of afterglow can be solved, and practically high flame retardancy can be obtained. I have. This is because the generation of decomposition gas containing water of the specific hydroxide used together, the endothermic effect, the reaction temperature, the carbonized flame retardant effect, etc. are different from those in the case of Sb compounds. It is presumed that they complement each other with flame retardancy.

In general, the flame retardancy of fibers is measured and evaluated in the state of a woven fabric. However, in woven fabrics, the flammability differs depending on the number of twists, thickness, and number of threads, and the practical use of the fiber composite itself Since it was not possible to evaluate the proper flammability correctly, the LOI value using Koyori was described as the value of the flame retardancy evaluation. The higher the LOI value, the less it burns and the higher the flame retardancy.
