The name was used in the Netherlands for a twiil weave with a combed warp and a carded weft.
The name is linked to ancient Greek serikos, 'silken'. Its eastern origins were made apparent with the discovery of a fragment of what is described as silk serge in the tomb of Charlemagne, possibly originating from the court of Constantinople.
A lighter variety of serge is called say (saai in Dutch). In Leiden the serge production was part of the so-called saai-nering (say-industry), one of the seven textile neringen [industries]).
