Innovation application: Amber Composite Fibre

Title Amber Composite Fibre

A new type of the product has been developed – amber composite fibres, which has significant advantages compared with the known polymer composite fibres, in particular, fibres with the smooth surface. The amber composite fibres have bioactive properties of amber threads and retain physical and mechanical properties of the purified amber.

Description of the technology

The main feature of the invention, namely, amber composite fibre, is that it contains technologically processed amber powder, preferably succinite (CAS No. 9000-02-6), with the particles of spherical form and particles in sizes up to 3 mkm crushed to graininess less than 1/3 of the set fineness of fibre filament,

evenly integrated into thermoplastic polymer matrix, preferably polyamide 6 (CAS No. 25038-54-4), colophony powder (CAS No. 8050-09-7) and silver powder (CAS No. 7440-22-4), with the following ratio of components: microstructurized succinite: 0.1-10 mass %, PA6: 90-92.9 mass %, colophony powder: up to 2 mass %, silver powder: 0.5 mass %.
The quality and safety of the product is confirmed by

  • Certificate Oeko-Tex® Standard 100 AITEX Nr. 2913LK0012 23.09.2013. Composite Amber fibers in raw. Composite amber fibers blends with cotton, linen, wool and silk in raw. Extended to 30.09.2015. Composite Amber fibers in raw;
  • Certificate Oeko-Tex® Standard 100 AITEX MADE for HEALTH Nr. 2014TM0281 27.05.2015. Composite Amber fibers the products of personal hygiene and medical devices;
  • SAFETY DATA SHEET According to Regulation (EC) Nr. 1907/2006 (REACH) 19/08/2013. Baltic Amber Powder.


Applications The developed amber composite fibres are designed to widen the range of textile materials and can be used also as a prophylactic material in case of occurrence of various skin changes, including facilitation in improvement of skin condition in case of diabetes and manufacture of textiles for surgical purposes.

Amber composite fibres do not cause allergic reactions, stimulate epidermis activity, facilitate normal regeneration of skin areas, reflect ultraviolet rays, prevent blood clot formations from coming in contact with platelets and from biocompatibility of the latter with the living tissues. Moreover, the effect of the technologically processed succinite lasts over one year.

Technology Readiness Level System complete and qualified
Partnership offer Cooperation with wholesalers to distribute amber composite fibre. Joint research projects to improve technology. Other forms of cooperation by mutual agreement.
