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 study revealed that an increase in B.R. reading and Iodine value are due to blending with groundnut oil and hydrogenated fat, also an increase in the polenske and saponification values are due to blending with coconut oil where as decrease in the B.R. reading and Iodine value are due to blending with coconut oil and decrease in the Reichert–Meissl, Polenske, saponification values are due to blending with hydrogenated fat and animal body fat at 10 & 15 per cent respectively.
