This eco-friendly material promises to revolutionize the leather industry with its impressive strength and sustainability.
The results are published in Sustainability . The process begins with the extraction of pineapple leaf fiber from waste pineapple leaves through a mechanical method, showcasing a clever use of agricultural waste. The extracted fibers are then divided into two categories: untreated (UPALF) and sodium hydroxide-treated (TPALF) to widen the leather properties.
These fibers are formed into non-woven sheets using a paper-making process, which are then coated with compounded natural rubber latex in various NR/PALF ratios. To enhance the material's properties, an adhesion promoter could be added. The resulting leather-like materials were rigorously tested for tensile properties, tear strength, and hardness, with their internal structures examined using a scanning electron microscope.
The study, led by Professor Taweechai Amornsakchai from Mahidol University, found that the leather alternative with an PALF/NR ratio of 50/50 was the most satisfactor.
