Monofilament yarn, as evident by its name, consists of a single solid filament. The diameter range of monofilament yarns is 100–2000 μm which is widely used as fishing line, dental floss, in sports racquets, and bristles of tooth brushes or softer sewing thread applications. UTS Polyblends is one of the leading yarn colour masterbatch manufacturers who has range of such masterbatches.
