Security Threads

We have developed one of the most secure security threads on the market today, these include a variety of substrates comprising single and multi-colour sewing threads with vivid fluorescent characteristics. In addition to the great fluorescent characteristics, our threads run smoothly on both Uno and Kugler passport binding machines.

Reliable, discreet and technically advanced.

At Liberty Security Threads, we develop and produce high-performance sewing threads equipped with security features that help protect products, packaging, and brands against tampering, counterfeiting, and substitution.

Our security threads can be used to sew labels, apparel, and leather goods, providing a low-cost, counterfeit-resistant solution for a wide range of branded items. These threads can be twisted or braided using carefully selected materials and plies to ensure both high-quality performance and unique identification characteristics that are difficult to replicate.

For high-end brands, we offer specialized threads equipped with machine-readable, invisible taggants, which can be seamlessly integrated into finished goods such as fashion items, accessories, or packaging. These taggants remain undetectable to the naked eye and can be verified using handheld or inline readers, tools we can help supply through our trusted technology partners.

This enables luxury brands to authenticate their products at any stage of the supply chain without disrupting the aesthetic of their items. It also provides a discreet method of ensuring brand integrity and tracking original goods, essential in an era of rising counterfeiting.

Together with our partners we offer complete end-to-end solutions, combining secure threads with compatible reader technologies, enabling a smooth implementation and a high level of supply chain protection.

Our brand protection threads are also used in technical, industrial, and agricultural markets, where supply chain security and product authenticity are critical.

Examples include:

• • Agriculture: Sewing seed bags with security threads ensures that the contents are not tampered with or mixed during distribution. Farmers can easily verify authenticity using a UV light or handheld reader.
  • Defense and aerospace: Protect sensitive goods by ensuring the packaging has not been opened or altered during transport from manufacturer to end user.
  • Technical processes: Confirm that the correct technical textiles and soft goods (such as specific fabrics) have been used in manufacturing environments.

Our threads provide a visible or invisible verification method, giving peace of mind in markets where control, traceability, and product integrity are paramount.

Thanks to our fully vertical manufacturing setup, we can integrate security features into almost any type of fiber, including polyamide, polyester, Nomex®, and more. We offer various security solutions from UV-reactive markers to advanced taggants, all engineered to meet the specific needs of your product or industry.

And if your requirements go beyond our existing portfolio, our in-house development team is ready to work closely with you to create a customized solution.
