  • Patent number: 8802756
    Abstract: An object to be achieved by the invention is to provide a biodegradable low-charging fiber. The prevent inventors have found that when a specific amount of a specific phospholipid that is not known to have antistatic properties is added to a biodegradable polymer, and the resulting mixture is formed into a fiber having a smooth surface, low-charging properties are developed. The invention has thus been accomplished. The invention is a fiber having an average surface porosity of less than 3% and made of a biodegradable polymer that contains a specific amount of a specific phospholipid.
