In her book Dyes & Paints: A Hands-On Guide to Coloring Fabric:
Elin Noble recommends to scour all fabric, even fabric prepared specifically for dyeing, before use.
I used Elin's recipe for washing-machine scour with Synthrapol and soda ash. Today's wonderful Spring day did the rest and made the fabric smell like sunshine. Soon dyeing can take place, if the weather remains the same.
