Zusammenfassung:	PURPOSE:To obtain the title fiber which is composed of a polyamide containing specific amounts of a benzoxazole fluorescent brightener, a white inorganic compound and a dispersion medium respectively, thus showing satisfactorily fluorescent brightness, excellent weather resistance and color fastness and melt- spinnability. CONSTITUTION:The objective fiber is obtained by using a polyamide containing (A) 0.01-0.07wt.% of a benzoxazole fluorescent brightener, (B) 0.2-3wt.% of a white inorganic compound, and (C) a dispersing medium. The component A is preferably 4,4'-bis(2-benzoxazolyl)stilbene and its derivative. The component C is preferably a liquid polyester ether. Further, a liquid mixture consisting of components A, B and C is quantitatively fed with a gear pump or the like and injected into the melted polyamide.
