摘要： A problem of the present invention is to provide a composite yarn, a fabric, and a fiber product, which are excellent in cotton-like appearance, texture, and snagging resistance, and preferably excellent in see-through-preventing properties and water absorbing and quick drying properties. The solution is to obtain a composite yarn using a thick and thin yarn and a crimped yarn and to obtain a fabric, if desired.

摘要： 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.
