Can you tell me the age of this fabric?

thanks for help on describing and dating this seersucker fabric. Mom passed on this year and we have a lot of fabric she has been collecting for years.

Looks 1970s to me.

Fortrel is a trademark for a type of polyester. Looks like it was filed in 1965, and so your fabric is unlikely to be earlier than that. I'm expect Barbara is right about 1970s. It's a wonderful fabric, I love it!
