Silk


Silk weaving yarn - Understanding the basic measurements of silk diameter

The thickness of all Pure silk is measured in denier (the weight in grams of 9000 metres in length = 9000-meter strand of silk weighs about one gram)

The basis of all of our silk weaving threads starts with 20/22 thread - this is extremely fine continuous filament silk. We do supply the 20/22 denier continuous filament silk - Raw or de-gummed but unless you have good winding equipment you will find it impossible to wind from the skein. 

The term 20/22 relates to the fact that there can be 10% difference in the thickness of a single cocoon thread due to having fat silk worms and thin silkworms in a harvest.


Singles = Lightly twisted
Tram = Lightly twisted
Organzine = Tightly twisted
Dupion - Lightly twisted


20/22 thread is made on average from 7 single cocoon threads, twisted together.

  • 20/22 denier thread singles = 1 end of 20/22 lightly twisted together for warp or weft
  • 40/44 denier thread Organzine = 2 ends of 20/22 tightly twisted together for weft yarn only
  • 60/66 denier thread Organzine = 3 ends of 20/22 tightly twisted together for warp thread only
  • 80/88 denier thread Organzine = 4 ends of 20/22 tightly twisted together for warp thread only
  • 100/120 denier thread Dupion = 5 ends of 20/22 thread lightly twisted together but made from broken cocoons which create Dupion Silk which is for weft only but gives a slub effect when woven.
  • 120/132 denier tram = 6 ends of 20/22 denier lightly twisted together for weft yarn only (this thread forms the basis of our embroidery thread range 6 thread)
  • 200/250 denier Dupion = 10 ends of 20/22 thread lightly twisted together but made from broken cocoons which create Dupion Silk which is for weft only but gives a slub effect when woven.
  • 240/264 denier Tram = 12 ends of 20/22 thread lightly twisted together for warp or weft

So to summarise, the smaller the number, the finer the yarn will be - Think of stockings and tights, they are still measured in denier and the smaller the number the finer and more delicate the tights and stockings will be.

We can supply other denier of silk on request.
