Eco friendly functional finishes of polyester fabric using keratin from wool and feather wastes
Lidija Fras Zemljič, Maja Čolnik, Darinka Fakin, Tanja Pušić, Vanessa Wendy Bračko, Tjaša Kraševac Glaser, Mojca Škerget, 2024, izvirni znanstveni članek

Opis: This research showcases the use of hydrothermally extracted solutions from poultry feathers and wool as ecofriendly and versatile textile finishes. These solutions, derived from waste biomass containing the keratin biopolymer, were obtained through environmentally conscious hydrothermal degradation processes. Initially, the study focused on analysing the chemical parameters and properties of both dialysed and non-dialysed solutions extracted from feathers and wool. The investigation tracked primarily the presence of keratin within these solutions. Upon application to polyester textiles as the reference material, the presence of these solutions on the fabric surface was confirmed successfully. A thorough physicochemical analysis of the treated textiles involved various analytical techniques. These encompassed surface composition analysis via X-ray Photoelectron Spectroscopy (XPS) and Attenuated Total Reflectance Fourier Transform Infrared Spectroscopy (ATR-FTIR), assessment of wettability through Contact Angle measurements, determination of surface charge using surface zeta potential, and examination of the thermal and flame-retardant properties via Differential Scanning Calorimetry (DSC), Thermogravimetric Analysis (TGA), and calorimetric tests. In addition, the colour, UV radiation transmission and antioxidant activity were evaluated using standard tests. The remarkable effects of the treatment have been observed in the exceptional antioxidative action, fire resistance, UV protection and enhanced hydrophilicity of these innovative multifunctional textiles. This approach holds significant implications across research, economics and society, enriching Material Science by deepening the understanding of materials and their multifaceted properties. Moreover, it promotes resource efficiency, opens new sustainable textile market prospects, and contributes to social impact by supporting environmental sustainability, engaging communities and ensuring health and safety benefits.

Funkcionalizacija tekstilij z uporabo biopolimerov iz odpadnih mas : diplomsko delo
Vanessa Wendy Bračko, 2023, diplomsko delo

Opis: Diplomsko delo je usmerjeno v dokazovanje multifunkcionalnosti tekstilij, na katere so bile nanešene 4 apretirne raztopine, ekstrahirane iz odpadne biomase perutninskega perja in volne (ki vsebujeta biopolimer keratin) s pomočjo zelene hidrotermalne razgradnje. Polovica vzorcev je bila dodatno dializirana skozi dializno membrano. Najprej so bili določeni kemijski parametri in lastnosti ekstrahiranih raztopin (dializirana in nedializirana raztopina iz perja, dializirana in nedializirana raztopina iz volne), s poudarkom na sledenju biopolimeru keratinu. Po nanosu raztopin na poliestrsko tekstilijo, kot referenčno tekstilijo, je bila dokazana prisotnost teh raztopin na površini tkanine. Prav tako so bile analizirane nove multifunkcionalne lastnosti tekstilij. Najopaznejši doprinos k lastnostim se kaže v izjemnem antioksidativnem delovanju, ognjevarnosti, UV zaščiti in hidrofilnosti novih multifunkcionalnih tekstilij.
