Bella Solids Bleached White PFD 9900 97S
PFD - Prepared for Dyeing. It means that the fabric - or garment - is specially made to be dyed. PFD fabrics have been desized, scoured, and fully bleached, and they have not been finished or processed with optical brighteners or softeners that can interfere with dye uptake, resulting in fabrics that lack saturated color or are not evenly dyed.
