Abstract
A fiber article includes a plurality of first fibers and a plurality of second fibers each having an outer diameter smaller than that of each of the first fibers, the plurality of second fibers being supported in a dispersed state by the first fibers. A ratio D1/D2 of an outer diameter D1 of the first fiber to an outer diameter D2 of the second fiber is set to a value in a range of 15.0 or greater to 1666.7 or less. The outer diameter D1 is set to a value in a range of 5.0 μm or greater to 50.0 μm or less, and the outer diameter D2 is set to a value in a range of 30.0 nm or greater to 1.0 μm or less.

A fiber article, comprising:
- a plurality of first fibers;
- and
- a plurality of second fibers each having an outer diameter smaller than that of each of the first fibers, the second fibers being supported in a dispersed state by the first fibers,
- wherein the first fibers consist of one of rayon, polypropylene, polyethylene terephthalate, polyethylene, or cellulose acetate, and the second fibers include at least one of polytetrafluoroethylene, polypropylene, polyethylene, or polyamide, where the first fibers consist of a material different from that of the second fibers,
- a ratio D1/D2 of an outer diameter D1 of the first fiber to an outer diameter D2 of the second fiber is set to a value in a range of 15.0 or greater to 1666.7 or less,
- the outer diameter D1 is set to a value in a range of 14.64 μm or greater to 50.0 μm or less, and
- the outer diameter D2 is set to a value in a range of 30.0 nm or greater to 800 nm or less.
A fiber article comprising:
- a plurality of first fibers;
- a plurality of second fibers each having an outer diameter smaller than that of each of the first fibers, the second fibers being supported in a dispersed state by the first fibers;
- and
- resin particles attached to the first fibers and made of a composition similar to that of the second fibers,
- wherein the second fibers include at least one of polytetrafluoroethylene, polypropylene, polyethylene, or polyamide,
- the first fibers include a material different from that of the second fibers,
- a ratio D1/D2 of an outer diameter D1 of the first fiber to an outer diameter D2 of the second fiber is set to a value in a range of 15.0 or greater to 1666.7 or less,
- the outer diameter D1 is set to a value in a range of 14.64 μm or greater to 50.0 μm or less,
- the outer diameter D2 is set to a value in a range of 30.0 nm or greater to 800 nm or less, and
- a ratio V1/V2 of a total volume V1 of the first fibers and a total volume V2 of the second fibers and the resin particles is set to a value in a range of 1.9 or greater to 124.0 or less.
A fiber article comprising:
- a plurality of first fibers;
- and
- a plurality of second fibers each having an outer diameter smaller than that of each of the first fibers, the second fibers being supported in a dispersed state by the first fibers,
- wherein the second fibers mainly include polytetrafluoroethylene,
- the first fibers include a material different from that of the second fibers,
- a ratio D1/D2 of an outer diameter D1 of the first fiber to an outer diameter D2 of the second fiber is set to a value in a range of 15.0 or greater to 1666.7 or less,
- the outer diameter D1 is set to a value in a range of 14.64 μm or greater to 50.0 μm or less, and
