Abstract: A fiber powder having a 50% particle diameter (d50) of 6 to 60 μm, characterized in that the fiber powder has a maximum particle diameter (d100) of 1,000 μm 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.

Abstract: The invention addresses the problem of providing a flap-equipped knitted fabric including a flap part, which is configured such that the flap part moves when wet, allowing for changes in the air permeability or appearance of the flap-equipped knitted fabric, and also a textile product. As a means for resolution, for example, in a flap-equipped knitted fabric including a ground structure part and a flap part, the flap part is pouch-shaped, and the flap part contains a conjugate fiber obtained by joining a polyester component and a polyamide component in a side-by-side manner or an eccentric sheath-core manner, thereby making the flap part movable upon wetting.
