Quick household question:
Most polyester clothing, I think, calls for low dryer temperatures, but what if you run it on high? High for an extended time? It doesn’t seem to melt or anything, but is it melting in an invisible way?
According to an article on buzzle.com: “the heat can cause it to melt, shrink, loosen, discolor, or deform”
I believe you are asking about the Heat Deflection Temperature. Hereis a table for common polymers .
For PET (common polyester) this temp is around 108 deg-C
Whatever you do, don’t put one of those expensive Pro sports team jerseys in a commercial dryer at the laundromat (if it’s polyester), and turn it on high. I learned that the hard way.
It was melted beyond all recognition. :mad:
An former boy friend of mine ( flight attendant ) told me never wear synthetics on a plane… always wear cotton and leather ( denim pants and shirts and leather shoes.) cause it is less likely to melt in to your skin in an “accident” and rubber soles shoes will melt into the floor of an MD11 like Crayola Crayons on a radiator in January…
This may well be very accurate advice, but I cannot fathom choosing my clothing based on how it would react in a plane crash/incident. If I was specifying fabric for flight attendant uniforms, I would absolutely care…but if I’m getting dressed to jump on a plane? Never.
