Applied DNA Sciences (APDN), a specialist in DNA-based anti-counterfeiting technology, is claiming success in a large-scale trial of its cotton authentication process.

The news comes a week after the company announced a tie-in with Supima, the US trade association for luxury Pima cotton growers, but APDN stressed that the two were not connected.

This latest trial of the Signature T anti-counterfeiting platform involved one of the world’s foremost textile organisations, APDN said, and took place at an undisclosed location outside the US.

In the trial, APDN applied an uncopyable Signature DNA mark of authenticity to five tons of extra long staple cotton.

The company said its scientists were able to detect the difference between the real and fake cotton at every stage of the logistics chain, from ginning, through roving, to the finished product – and despite processing, industrial washing and other stresses.

APDN added the technology would counter the threat of cheap cotton posing as luxury cotton and the theft of intellectual property such as logos, labels and brands.

“We believe that the great success of this trial shows that the APDN anti-counterfeiting platform for textiles will be the worldwide gold standard for brand identity assurance in textiles,” said Dr James Hayward, APDN CEO and president.

“APDN can now mark massive volumes of product, on both American and foreign soils, and assure integrity of the textile supply chain at an unprecedented level.”
