Thread size (dD)

dD = average thread diameter in 10 micrometres · dD 100 = 1 mm, dD 10 = 0.1 mm

Ø mm
The diameter in millimetres: dD divided by 100.
20 : 1
The line next to each value shows the size. All lines are drawn in the same proportion – a line twice as thick means a thread twice as thick.
No longer produced
The thread is no longer made. It stays in the database because it still turns up in collections and old patterns.

Presentation (twist & put-up)

The -S and -Z markings refer to the twist / plying direction of the threads. Detailed explanations can be found in the book “Faden & Brief: Ein Zusammenspiel”.

Twist

Drawing of a thread with S-twist
S-twistThe thread runs from top left to bottom right – like the middle stroke of the S.
Drawing of a thread with Z-twist
Z-twistThe thread runs from top right to bottom left – like the middle stroke of the Z.
Example 2S-3Z

A two-stage ply: in stage 1, 2 threads are twisted in S direction. In stage 2, 3 threads of stage 1 are plied in Z direction.
