Vinymo MBT expresses the thread diameter as No. 00, No. 0, No. 1, No. 5, No. 8, and No. 20. "No." means yarn count and is a unit of measurement for the thickness of the thread in spinning. It is also called "Bante" in Japanese. The lower No., the thicker the thread diameter.
No. 00: 1.0 mm / 0.04 in / Extra Heavy, Heavy Duty
No. 0: 0.7 mm / 0.028 in / Extra Heavy
No. 1: 0.6 mm / 0.024 in / Slightly thinner than V207, Tex 210
No. 5: 0.5 mm / 0.02 in / Slightly thicker than V138, Tex 135
No. 8: 0.4 mm / 0.016 in / Approx. V92, Tex 90
No. 20: 0.3 mm / 0.012 in / Fine
Please note: Vinymo MBT and Tex/V thread sizes use different sizing systems. The comparisons above are approximate and should not be considered exact equivalents. Thread construction, twist, and measurement methods can affect perceived and actual thickness.
