  • Patent number: 11186677
    Abstract: A fiber powder having a 50% particle diameter (d50) of 6 to 60 ?m, characterized in that the fiber powder has a maximum particle diameter (d100) of 1,000 ?m or less. It is preferred that a value ((d10·d90)/d100) obtained by dividing by the maximum particle diameter (d100) a value which is obtained by multiplying a 10% particle diameter (d10) by a 90% particle diameter (d90) is 0.3 to 5.0, that the fiber powder has an extractable component content of 0.2 to 3.0% by weight based on the fiber weight, and that the fiber powder has a water content of 0.2 to 50% by weight. Further, it is preferred that the fiber powder is an organic material, or comprises a thermoplastic resin, and that the thermoplastic resin is a polyester resin or a polyamide resin.
