A method may include melt spinning a polymer composition to produce a yarn, where the polymer composition includes a polymer at an amount ranging from 95 wt % to 99.99 wt %; a carbon-based nanomaterial at an amount ranging from 0.01 wt % to 5 wt %.

A multilayer ceramic capacitor is disclosed including a first external terminal disposed along a first end of the capacitor, a second external terminal disposed along a second end of the capacitor opposite the first end, an active electrode region containing alternating dielectric layers and active electrode layers, and a shield electrode region including at least two shield electrodes that are spaced apart by a shield layer gap in the longitudinal direction. The distance from the active electrode region to the shield electrode region may range from about 4% to about 20% of a thickness of the capacitor between a top surface and a bottom surface opposing the top surface. The shield layer gap may range from about 3% to about 60% of an external terminal gap between the first external terminal and second external terminal in the longitudinal direction on at least one of the top or bottom surfaces.

Disclosure provides a twisted and heat-set Bulked Continuous side-by-side bi-component Filament (BCF) yarn including a plurality of side-by-side bi-component filaments, each includes first and second polymer components. The first polymer component forms a first side of the side-by-side bi-component filaments, and includes polybutylene terephthalate (PBT) in at least 25 and up to 75 volume percent of the filament in the BCF yarn. Further, the second polymer component forms a second side of the side-by-side bi-component filaments, and includes one of polyethylene terephthalate (PET) or polylactic acid (PLA) in at most 75 and down to 25 volume percent of the filament in the BCF yarn. The twisted and heat-set BCF yarn is obtained by a single-step continuous process, and subsequently followed by steps of twisting and/or cabling and heat-setting. The twisted and heat-set BCF yarn as obtained exhibits an elongation to break in a range of 40% to 65%, and floor covering manufactured from the yarn exhibits a Hexapod rating after 12000 cycles of more than 2.
