Abstract: A non-woven fiber article for use in a food, medical, or pharmaceutical production environment including a melt-spun polymer fiber is provided having a cross-section and a length and a detectable particulate present in an amount of 20 to 80 weight percent loadings of metal or 10 to 80 weight percent loadings of radiopaque particles to render the polymer fiber detectable by magnetic or X-ray detection, alone or in combination with a secondary functional particulate distributed with the polymer fiber to render the polymer fiber chemically responsive to a chemical reactant, change in pH or temperature. The detectable particulate and the secondary functional particulate are each independently present in a core, a sheath, or both portions of polymer matrix. A process of detecting a fabric made from such a fiber. The fabric article passes through detector. A signal is collected from the detector indicative of the presence of the fabric article.

Abstract: A melt-spun polymer fiber is provided having a cross-section and a length. A detectable particulate has a size of less than 31 microns and present in an amount of 2.0 to 50.0 weight percent loadings of metal or 10 to 80 weight percent loadings of radiopaque particles to render the polymer fiber detectable by metal (magnetic) or X-ray detection, alone or in combination with a secondary functional particulate distributed in or on the polymer fiber to render the polymer fiber chemically responsive to a chemical reactant, change in pH or temperature. The detectable particulate and the secondary functional particulate are each independently present in a core, a sheath, or both portions of polymer matrix.

Abstract: A fiber is provided with a polymer having a cross-section and a length. A particulate is distributed in the polymer in an amount to make the fiber detectable by X-ray detection or magnetic detection. The particulate is present in a core, a sheath, or both portions of polymer matrix. A process of detecting a fabric article is provided that includes the formation of a fiber in the form of a polymer having a cross-section and a length. A particulate is distributed in the polymer. A fiber is formed into a fabric. A fabric article is then manufactured from the fabric. The fabric article passes through an X-ray detector or a magnetic detector. A signal is collected from the X-ray detector or the magnetic detector indicative of the presence of the fabric article.
