This is a very delicate fabric and should be treated as such.
It should be treated the same way as you treat your silk or satin items.
Any harsh objects or constant rubbing in the same area will cause pilling of the fabric.
Wash garments or fabric by hand in cold water and very little soap and make sure all soap has been rinsed out of the fabric.
Turn garment inside out before washing.
Do not dry in direct sunlight or in the dryer.
