17th February 2021

There is clear and growing social awareness of today’s environmental problems. The market is demanding more use of reused or recycled materials, and the emergence of recycled polyamide must be faced as an unavoidable challenge.

AITEX is in the final stage of the MARNET project, which focuses on developing new textile yarns from polyamide fibres obtained from recycled fishing nets. These sustainable and environmentally friendly yarns reduce the amount of waste produced from the use of fishing nets, and therefore the contamination from accumulated textile waste.

The results are:


New formulations using additivated recycled PA:

  • UV – improved resistance to sunlight
  • UPF – protects the skin from UV rays
  • FR – flame retardancy
  • FIR – reflects the body’s infra-red radiation with therapeutic effects for cells
  • NI – releases negative ions with numerous benefits for the wearer


Optimising multifilament meltspinning using recycled polyamide to attain the best possible mechanical properties.

The development of innovative functionalised yarns from blends of recycled polyamide and natural fibres of recycled cotton and wool).

The results have a high R+D content as sustainable fabrics have been developed from functional yarns with excellent physical and mechanical properties for technical uses: sportswear, PPE, etc.
