In the future, DNA evidence may enable comprehensive counterfeit protection in the textile industry. In addition to a special DNA analysis for the authentification of cotton products, artificial DNA marking should serve to counterfeit-proof textiles.

This DNA process was developed by the American security service provider Applied DNA Services (ADNAS). The company uses internally developed high-tech solutions, such as the so-called fiberTyping and the DNA product identification system SigNature T.

The process known as fiberTyping is a patented test in which the cotton used in textiles can be tested for authenticity using DNA traces, which make it possible to exactly determine the degree of fibre purity. This process can immediately identify textile counterfeits mixed with low-quality fibres.

With its SigNature T tagging system, the company even goes a step further: Invisible signatures based on plant DNA are applied to textile fibres such as cotton. The microscopic markings can be produced to be absolutely unique in order to protect specific manufacturers, brands, or products against counterfeiting.

The artificial DNA has a unique characteristic: It can be applied to raw materials, making it possible for cotton textiles to be secured and inspected at every point in the manufacturing process using a “tag” applied to the cotton fibres directly after harvest.

The artificial DNA is highly resilient, and is not damaged by further processing of the fibres. And the form and function of the fibres are not affected by the marking, according to Jim Hayward, ADNAS chairman. Apart from cotton, SigNature T can also be applied to other natural as well as synthetic fibres.
