Abstract:

 

Polymer blending as an efficient method for blending at   least two~polymers is usually used to create new materials with desirable   physical properties. This article focuses on the biodegradability evaluation   of polypropylene (PP) fibers modified with disposable recycled poly(lactic   acid) (r-PLA) plastic flakes. Biodegradable modified PP fibers containing   30% r-PLA were prepared by melt spinning process and evaluated with   different methods of biodegradation assays. The soil burial test method,   CO22_{2} evolution analysis, weight loss, mechanical properties, and average   molecular weight measurements and analysis of surface morphological changes   were performed for biodegradability evaluation of the modified PP fibers.   Surface morphology of the blend fibers illustrated that by increasing the   soil burial period cracks were formed on the surfaces of fibers. While   different testing methods showed different values for the biodegradation   process, the results obtained from the CO22_{2} evolution analysis, weight   loss, and variation of mechanical properties confirmed a good agreement   between different degradation methods. After incubation in soil for a long   period of time, the initial moduli and tenacity of the modified fibers   decreased up to 72% and 53%, respectively. In addition, the average   molecular weight measurement showed a 28% decrease in average molecular   weight after 80 days of soil burial.
