SLEEVES UP!

摘要

A shirt which rolls up its own sleeves when you get too warm has been unveiled by atech-sawy Italian fashion house. And what's more, its inventors say it will never need ironing. The fabric for the prototype shirt is woven from fibres of the shape-memory alloy nitinol, interspersed with nylon. The alloy can be deformed, and then returned to its original shape when heated to a certain temperature.
