Does silk shrink?
Yes, silk does shrink.
How much silk shrinks depends on the silk fabric and how tightly it is woven. If the threads are tightly woven the silk fabric will shrink less than a loosely woven silk fabric.
For example, Habutai and Paj (tightly woven) are likely to shrink less than Crepe de Chine, Gauze, Silk/Cotton (looser weaves).
Allow for silk shrinkage
If you are using silk to make clothes please make allowance for silk shrinkage. It is recommended that you pre-shrink your silk by hand washing it in cold water with a mild detergent or a gentle shampoo. Dry it by rolling it up in a towel to remove excess water.
