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.
