Nonwoven fabrics are provided that include a mechanically entangled blend of fibers comprising (a) post-consumer recycled polymer staple fibers (PCR-staple fibers) and (b) one or more additional fibers, in which the one or more additional fibers are different than the PCR-staple fibers. The PCR-staple fibers are mechanically entangled with the one or more additional fibers to define the nonwoven fabric.

The present invention provides, for example, a melt-blown nonwoven fabric that is tear-resistant and that has high particle filtration efficiency. The present invention is, for example, a melt-blown nonwoven fabric including fibers. The fibers are formed from a resin composition that contains a poly(3-hydroxyalkanoate)-based resin. The poly(3-hydroxyalkanoate)-based resin includes a copolymer including a 3-hydroxybutyrate unit. A content ratio of the 3-hydroxybutyrate unit in the poly(3-hydroxyalkanoate)-based resin is greater than or equal to 80.0% by mole and less than or equal to 93.5% by mole. An average value of fiber diameters of the fibers is less than or equal to 8.0 m.

A method is disclosed for spinning a biodegradable polyester copolymer filament. A biodegradable polyester copolymer melt is formed by polymerizing terephthalic acid, ethylene glycol, caprolactone monomer, calcium carbonate, and poly butylene succinate to form a biodegradable polyester copolymer melt. The biodegradable polyester copolymer melt may be spun into a biodegradable polyester copolymer filament.

An implantable medical device includes a wire frame, a cover, and a sensor. The wire frame is formed of struts and openings. The cover connects to the struts of the wire frame. The cover is fashioned from a fabric including a PET fabric made of PET yarn and a ferromagnetic material combined with the PET fabric. The PET yarn is made from a plurality of PET fibers. The sensor is positioned on the cover and connected to the wire frame. The cover shields the sensor from detuning effects of the wire frame.
