Hence your machine will run longer between cleanings. This thread is very shiny appearance, thin, lightweight and yet extremely strong. Embroiders love this since it creates a soft backing, even on dense designs. Many machine quilters like using a filament poly thread in the bobbin. Due to it's slick surface, it works well with metallic threads and heavy cotton threads. The slickness of the filament poly thread does not snag or grab the top thread.
