く知られている(例えば、特公昭43−14185)。It has been well known to spin two or more component polymers into a multilayer core-sheath shape for the purpose of modifying various physical properties of synthetic fibers (for example, Japanese Patent Publication No. 14185/1985).

れる。In general, multilayer core fibers exhibit a special pearl-like luster, or fibers with a silk-like luster that cannot be obtained with triangular cross-section yarn, and spinning components with high dyeability have poor physical properties. By adding ingredients with high dyeability to one layer of the multilayer to give it a dyeing effect, and adding ingredients with excellent fiber properties, Young's modulus, bending properties, torsion properties, etc. to the other layers, we can create products with good dyeability. Fibers with the same physical properties as conventional fibers, and flame-retardant spinning components in general, have inferior physical properties, but a component with excellent heat retardancy is placed in the outermost layer, and a component with excellent physical properties is placed inside. By adding it, it can be used as a heat-retardant fiber whose physical properties are comparable to those of conventional fibers.
