Polyester is what makes cotton wrinkle free. Of course lately they have discovered some other way to make 100% cotton wrinkle resistant--what I don't know but probably some chemical.

As to the age it could be pre 1960's. That is when they first discovered polyester and it was added to many fabrics, especially cotton. Any closer in age I couldn't tell you. The only way you would know for sure is to go through antique textile books and look for the pattern. It would help if you had a makers name. Is there anything stamped on the selvidge. Sometimes the name of the maker and the fabric's title is stamped there.

Other than this--I'm clueless

100% cotton or linen (maybe rayon) smells like burning paper and leaves ashes

With polyester added, it stinks and leaves a gooey residue.

Wool and silk smell like burning hair.

The design is of little girls wearing aprons and chef hats and they are cooking. One is holding a menu and there is a big black kettle. The small print that runs across the rest of the fabric is of little pastel veggies like yellow carrots and maybe pink...onions?

Still clueless!
