Swiss Nylon Sieves

Nylon sieves produced by SEFAR, Switzerland's world famous factory, are remotely fly-shaped and essential in sieving and serigraphy with such characteristics as very high quality of knitting, quality of yarn, not easy breaking of eye gaps, high stretching capability . It is very difficult to visually observe eye ranges in XXX types.
In XXX types, the eye range gets closed as the number grows; and as the number is smaller, eye range grows.
In GG types, It is the opposite. The eye range enlarges as the number grows; and as the number is smaller,eye range grows.
You can calculate the eye range in mm by dividing ‘micron’ digit into the number of 1000 in the table space below.
