Nylon Satin, Where to Buy?

[davepincermovement]

I have a set of good quality nylon satin sheets which I ordered from the US but they are getting a bit old now. I am trying to find the heavy nylon satin sheet sets is really tough. It is rarer than silk. I have look on Google but none to be found they are either acetate or polyester which are really not the same. Anyone recommend where to get them or where to buy nylon satin fabric online?
