Abstract: Flame retardant compounds including at least one of a group of specified phosphoryl compounds which have a phenylene group in the molecule are applied to fiber materials composed of polyester-based synthetic fibers. Sufficiently long-lasting flame retardancy may be imparted to polyester-based synthetic fiber materials without the use of halogen compounds.

Abstract: A method for preparing silk fibers crosslinked with an epoxy compound is disclosed. Silk fibers are soaked in an aqueous processing liquid containing a water-soluble epoxy compound and a catalyst wherein the solubility of the silk fiber is at most 30% by weight when the silk fiber is soaked in an aqueous 5 wt % sodium hydroxide solution at a temperature of 65.degree. C. for 60 minutes, and dyeing depth, K/S, at 520 nm with 9% owf of a red reactive dye, Color Index Reactive Red 63 at the temperature of 60.degree. C. for 60 minutes is at most 7.

Abstract: The present invention provides silk fiber crosslinked with an epoxy compound, characterized in that solubility of the silk fiber is 30% by weight or less when the silk fiber is soaked in an aqueous 5 wt. % sodium hydroxide solution at a temperature of 65.degree. C. for 60 minutes, and dyeing depth, K/S, at 520 nm with 9% owf. of a red reactive dye, color Index Reactive Red 63 at the temperature of 60.degree. C. for 60 minutes is 7 or less. The silk fiber has improved properties including long term resistance to light deterioration and resistance to fibrillation.
