There is 100 percent polyester clothing that has care tags “Tumble dry low.”

Then there is 100 percent polyester clothing that says “Do not tumble dry.”

Are there different…_versions_ of polyester? And if one uses a dryer to dry polyester that says “don’t dry in dryer,” is it going to melt the stuff?
