Cornell’s fashion design students were challenged to create an innovative evening ensemble, but the hitch to the task is that they had to do it with no thread and no glue.
So they turned to a process known as ultrasonic joining using the SeamMaster High Profile which has been used for body bags and bullet proof vests but not something as fine as cocktail and eveningwear to develop floral appliqu?s and spaghetti straps.
If you’re comfortable with basic physics you may have already figured out how this process works: the hi-freq waves are concentrated in a tiny single spot on the fabric which creates a rapid build up of heat. Since the fabircs used are mostly synthetic the heat allows the fabric to be fused together.
Cornell Chronicle has the details.
