Acrylic yarns were invented, in part, to avoid shrinking, as garments made out of natural fibers require special handling when laundering. Acrylic is also machine-washable and hypoallergenic, characteristics that differentiate the fabric from its natural-fiber counterparts.
Acrylic refers to a synthetic yarn that offers the wearer numerous advantages. The wool is easy to maintain, strong, durable and wears well. The only drawbacks of this type of material are that it doesn't offer a great deal of warmth and tends to pill if you don't wash it carefully. If ...
One of the main reasons for the creation of acrylic yarns was to avoid shrinking. Prior to the introduction of acrylic based yarns, most sweaters were knit with wool or cotton (and in some cases cashmere, silk and angora), which required special washing and drying.

Acrylic yarn won't shrink and putting it through a very hot wash won't make it happy! What you could do in a case like this is sew a band of soft elastic inside the brim/edge of the hat for a bit of extra grip (and to stop it falling down over your eyes!)
I would not expect the acrylic to change much after take up, but as Enorph pointed out, I think the cotton might shrink once wet-finished. The yarn I used had a bit of a "hard" finish, in contrast to the unmercerized cotton I am currently weaving with, which in combination with the structure choice, has a 20-25% take up and shrinkage rate!
Acrylic Knitting Yarns. If you want practicality, great value, and colors that pop, acrylic yarn is the best answer.
