Here is an overview. |

So it's more a chemical additive instead of a blend of fabrics like nylon and rayon |

Date: 12/29/12 1:44 PM I think it also has to do with the ratio of polyester. Like a 70% cotton and 30% poly blend is less wrinkle free than a 50/50% blend. ------ re-living my youth through sewing... |

Date: 12/29/12 2:19 PM I got a couple of 100% cotton shirts that are wrinkle free. More correctly wrinkle free if removed from the dryer promptly and hung up, much like poly-cotton blends. However it doesn't feel nearly as good as a traditional 100% cotton. It feels stiff/slick/crispy in comparison. I seem to recall something about "long lasting treatment" when I got them a few years ago from Lands' End, so it's not a permanent treatment.
But I have no clue what chemicals or process they used. |

Date: 12/29/12 4:35 PM Some synthetic fabrics are fairly wrinkle-free by nature, but when you're talking about cotton, it comes down to treating the fabric with chemicals like formaldehyde and silicone plus heat-curing, as described here.
There have been regulatory efforts to reduce the amount of residual formaldehyde, but some people are extremely sensitive to even small amounts. |
