Study reveals DNA molecular tagging an effective tool to authenticate denim

A new study published in the September/October 2018 issue of the AATCC Review shows, DNA molecular tagging is an effective tool to authenticate denim and maintains its integrity even after exposed to the rigors of bleaching and abrasion.

The study was conducted by Applied DNA Sciences Inc. (Applied DNA) and the Fashion Institute of Technology (FIT). It was published in the AATCC Review, a highly regarded publication of the American Association of Textile Chemists and Colors.

At the FIT labs in New York, denim swatches were treated with unique DNA molecular tags produced by Applied DNA, then subjected to stone and bleach washings. The samples were then analysed at Applied DNA’s laboratories in Stony Brook, where it was proven that the DNA tags remained intact and suitable for high quality forensic scale analysis. Based on the observed stability, DNA tags of this kind may soon be ready for testing at a full manufacturing facility to verify the authenticity of the finished denim garment.

This technology will enable brands and manufacturers to track their fibres from the farm through to the finished product, allowing for a more transparent supply chain. Traceability can also help verify certain sustainability claims about commodities and products, helping ensure good practices and respect for people and the environment in supply.
