Applied DNA Sciences, a US headquartered supplier of DNA based supply chain, authentication and genotyping solutions said its DNA based system; Signature T can be used to monitor, control or eliminate substitution of high value cotton fibres with unknown origin fibres. The Signature T uses forensic science to tag, type and test textile products.

The Signature T technology has a unique molecular tag that tags cotton fibres in the cotton gin, which are subsequently checked, at every step in the supply chain as it is converted into yarn, fabric and finished goods.

“In addition to Signature T, all the cotton is Fibertyped, which quantifies the native DNA within cotton fibres by species, prior to ginning, to ensure the original cotton species is present,” the company said.

In surveys held earlier, APDN examined the genetic content of retail products labeled 100 per cent Egyptian or 100 per cent Pima cotton, using Fibertyping.

According to Applied DNA, this technology quantifies the native DNA by species within cotton fibres contained in cotton products.

As per the company's research, first published five years ago, approximately 80 per cent of retail products did not comply with their '100 per cent' label. (AR)
