Please help identify this label: Iluerado, and the fabric of the item

Hi! I am looking to identifiy the label and figure out the decade and fabric of these pants. I cannot find information on the label, Illuerado, nor the fabirc, Press Guard (and is in a diagonal rib V-shaped pattern). Any help would be appreciated.

 

Pressgard is a fabric treatment - not a fabric. My guess is that you're looking at a synthetic (polyester) or perhaps a synthetic mix.

The label looks like the top has folded down, if you're able to unfold/unpick it, I think you will find the brand is "Elderado". I found this newspaper ad for Elderado separates from 1968, which is also approximately what I would date your trousers. It describes the fabrics as "easy-care blends with Dacron". Dacron is a polyester.
