Why does my silk taffeta have white spots?
Hi all! I’m unable to post a picture, but I was going through my fabric stash and found out that my black silk taffeta from Silk Baron has developed some strange white dots that seem to be in between the fibers. Rubbing at them with my fingers seems to smear some of the white dots, but doesn’t eradicate them completely. I’ve never washed the fabric—I just put it right into a storage bin upon receipt (which was about 3 years ago, and I haven’t really touched it since then). The fabric does not have a smell.
Does anyone know what might be causing these white spots or what they are?
