摘要
The present invention relates to fibers having excellent responsiveness to magnetic fields and excellent conductivity, as well as articles made of the same. In particular, the present invention relates to fibers having magnetic properties and conductivity, which are excellent in resistance to heat and responsiveness to magnetic fields in a unit where a magnetic field is applied, as well as in stability of conductivity when the humidity varies. In addition, the present invention relates to textiles using such fibers, knitted articles and cloths, such as non-woven cloths, short fibers, brush rollers made of short fibers, and electro-photographic apparatuses using brush rollers.;The fibers of the present invention are fibers having excellent responsiveness to magnetic field and conductivity, made of a polymer having fiber forming functions which contains magnetic material particles in spherical form having a saturation magnetic flux density of no less than 0.5 tesla. According to the preferred aspects of the present invention,(a) the average particle diameter of the above described magnetic material particles in spherical form is no greater than 5 µm,(b) the coercive force of the above described magnetic material particles in spherical form is no greater than 1000 A/m, and(c) the above described fibers are complex fibers which are made of magnetic layers that contain 20 wt% to 90 wt% of the above described magnetic material particles in spherical form, and protective layers where the content of the above described magnetic material particles in spherical form is less than 20 wt%.展开▼
