SUMMARY:

The search for alternative and environmentally friendly textile materials that meet the goals of the UN 2030 agenda for both processes and products has become increasingly frequent in recent years. Therefore, using upcycling to evaluate the potential of industrial waste in obtaining value-added textile materials is one of the most promising paths in scientific research and with a rich range of applications ranging from cosmetic textiles to medical textiles as well as a source of raw material to obtain new structures. Thus, this research analyzes the potential of a new natural textile fiber, derived from industrial fishing waste, as a promising option for the textile segment for technical and clothing applications. And with the specific objective of developing innovative products in yarn and fabric structures. To this end, microstructural characterization tests were carried out using X-ray Diffraction (XRD), Fourier transform infrared absorption spectroscopy (FT-IR), RAMAN Spectroscopy, thermal analysis of TGA/DTA and DSC, Classifiber, in addition to optical and scanning electron microscopy with field effect (SEM-FEG). The resistance test was also carried out in acid and base media, washing with non-ionic detergent to remove dirt present in the fibers and subsequently, its separation via the carding process. Em seguida, o material cardado foi submetido ao processo de formação de fita numa máquina Uster MDTA3, as fitas seguiram para o processo de fiação. Testes de resistência e alongamento foram realizados no fio produzido. Com o fio produziu-se a malha e com ela uma peça de vestuário tipo gorro. Os resultados obtidos comprovam a potencialidade destas novas fibras têxteis naturais derivada de resíduo industrial na obtenção de um fio de caráter inovador e sustentável, com aplicações em têxteis médicos e de vestuário.
