There is now a way to differentiate between designer
clothing and knockoffs. Chalmers researcher Christian Müller has produced a
thread with unique optical properties, which can be used to create invisible
patterns in fabrics that are only visible under polarized light.
According to Swedish Customs, trade in counterfeit and
pirated goods has exploded the past few years in Sweden, the EU and globally.
The situation impacts companies, their employees and unknowing consumers. It is
often difficult to see the difference between a genuine garment and a knockoff.
