Over the last week we have had two clients bring in clothing made with at least 80% Polypropalene. One was a Nike Singlet and the other a specialist Canoeing shirt. The first Singlet we tried Melted to half size in 2 seconds under the flash so we stopped immediately and started investigating. The second I did not touch and got abused because the client had promised the would be printed in 3 places in 4 colours. My investigation showed that these will melt at anything over 120 degrees Centigrade which makes printing of them somewhat hard. So you have been warned.
