Multi-functional Core/Sheath Bicomponent Nonwoven of Recycled Poly(ethylene terephthalate) Fibres as Thermal Insulators

Popis výsledku v původním jazyce

The consumption of poly(ethylene terephthalate) (PET) has experienced a surge in recent times, owing to the widespread use of single-use plastic bottles, particularly in the context of beverages and drinking water. PET, a thermoplastic polymer, is known for its recyclability, and the recycled variant is referred to as rPET. The incorporation of rPET in fiber manufacturing is favored due to its cost-effectiveness, and the functionalized rPET fibers present an innovative product that can be used in a variety of applications. This study aimed to functionalize rPET fibers using the spun-bond technique, imparting antibacterial and flame-retardant properties, which are commonly employed in thermal insulator products. Nano zinc oxide (nano-ZnO) was used to confer antibacterial functionality, while phosphorus flame retardant (PFR) was used to impart flame-retardant properties. The core-sheath bicomponent fiber structure was employed to achieve the desired outcomes. The extrusion process was used to incorporate PFR and ZnO as the core and sheath components, respectively, at various ratios. The presence of nano-ZnO on the fiber shell was confirmed by the EDX data. The flame retardant study was utilized to observe the level of burning damage. The findings of the study demonstrated that increasing the percentage of PFR (maximum 8%) resulted in a significant decrease in the damage distance of the nonwoven material, with reductions of up to 60 % was observed. Furthermore, the results of the antibacterial test indicated that the inclusion of an additional 3 wt% of ZnO resulted in a considerable reduction of the bacteria S. aureus and K. pneumoniae by about 99.96 and 98.79 %, respectively. Based on the results obtained, it was determined that the most effective functionalized fiber was synthesized by including 3 wt% of ZnO and 5 wt% of PFR. Moreover, the incorporation of varying proportions of additives resulted in modifications to the mechanical and thermal characteristics of the fibers. This work highlights the potential of functionalized rPET bicomponent fibers as viable candidates for thermal insulator products. The utilization of functionalized rPET bicomponent fibers as a sustainable alternative for thermal insulator products showcases the commitment to environmentally friendly solutions, contributing to the overall goal of sustainability in the manufacturing industry.
