The objective of this research is to recycle nonwoven fabric waste from medical gown– manufacturing process by using as a filler in high–density polyethylene (HDPE). Before nonwoven fabric waste was mixed with HDPE, this fabric waste was treated with 5, 10 and 15 %w/w of the fabric waste using the treatment time of 2, 3 and 4 hours. The chemical structure of treated fabric waste was confirmed by FT-IR spectroscopy while scanning electron microscopy was used to investigate its surface morphology. The samples were prepared by compression molding using the amount of fabric waste at 5, 10, 15, and 20 %w/w, respectively. After mechanical tests were employed, it was found that the fabric waste content, the amount of maleic anhydride and the treatment time affected the mechanical properties of filled HDPE. Each property was improved when different conditions were used. However, these properties especially impact strength of HDPE filled with modified fabric waste were better than HDPE filled with unmodified one.Downloads
