"The dyes used in these fabrics are reactive dyes: therefore, colors are stable and will not release dye. Prewashing fabric is not necessary.
If you choose to prewash, wash in cold water and damp dry. Complete drying process by air drying. This washing and drying method will retain the finish of the fabric."
Good explanation for today's fabrics.
