The GRAFE Group is presenting a new additive masterbatch in the field of counterfeit protection for synthetic yarns and fibers at the Techtextil 2013.
The patent-pending solution is based on a new combination of chemical substances for product marking which can be detected both qualitatively and quantitatively on the final application by means of XRF (X-ray fluorescence analysis). The new masterbatch for synthetic yarns targets both commodities and specialties based on PP, PA and PET.
The active ingredients in the marker masterbatch can reportedly be used in many plastic materials and cannot be destroyed during the normal processing of thermoplastics.
In addition, they are said to be resistant to solvents, scrubbing solutions, dye baths and spinning oils. This means that they can also be used in tub-dyed yarns if the additive is included into the uncoloured synthetic yarn.
It is possible to add colours to the masterbatch, thus providing customers with a complete solution. The marker masterbatch – as a stand-alone-solution – can be used with lower dosages, in general one percent by weight. It has no significant effect on the colouring or on the mechanical properties of the final application.
The GRAFE Group provides technical support and assistance during the first evaluation of the marker masterbatch with its own in-house lab by means of XRF-analysis. This testing device can otherwise detect heavy metals and other elements in any thermoplastic material (semi-finished and finished products, granulate).
