摘要：
A fiber wadding formed from a biodegradable polymer fiber containing calcium carbonate fine particles including silicon that is characterized in that hydroxyapatite is precipitated and scattered nearly uniformly on the surface of the biodegradable polymer fiber is disclosed. Further, a method for production of fiber wadding that includes the steps of heating and kneading silicon-containing calcium carbonate fine particles and a biodegradable polymer to produce a composite, dissolving the composite by mixing the composite with a solvent to obtain a spinning solution, processing the spinning solution into fiber wadding by using electrospinning method, and alternatingly immersing the fiber wadding in a calcium aqueous solution and a phosphate aqueous solution to cause precipitation of hydroxyapatite in an approximately uniformly scattered manner on the surface of the fibers is disclosed.
