Regenerated Cellulose-based Composite Strengthened with Post-consumer Polyester Garments
Summary
Researchers developed regenerated cellulose-based composite materials reinforced with shredded post-consumer polyester garments, demonstrating a method for recycling textile waste that would otherwise be landfilled or incinerated into value-added structural composite products.
Polyester garments have an extensive availability nowadays.However, most post-consumer garments are burned and landfilled, leading to extreme pollution and significant waste of resources.Therefore, sustainably and economically recycling this post-consumer polyester (PCP) fabric waste for essential value-added products is meaningful and necessary.In this study, waste polyester fabrics obtained from PCP garments have been utilized in the development of composite materials.First, PCP fabric was dissolved in a methanol and sodium hydroxide solution.Then, the polyester paste was regenerated on regenerated cellulose-based fabric (viscose), constructing a viscose-based composite.The physical, thermal, chemical, morphological, and mechanical properties were examined for the viscose and viscosepolyester (VP) composites.FTIR, XRD, SEM, and percent add-on confirmed the presence of polyester in the composite.In addition, an add-on percentage of 10.71, higher crystallinity of 55.20%, thermal stability, and about 21% higher tensile strength were observed.The results, as mentioned above, ensured that the PCP waste can be used as a matrix for composite materials.
