Production of POY Filament Yarns from used Polyamide 6
Polymers degrade very slowly in our environment. Therefore, they are considered as an important environment pollutant. Polyamide 6 is an example whose monomer is expensive relative to other polymers. Thus, recycling of polyamide 6 seems to be necessary to avoid environment pollution and economical reuse of wastes. In this study, to determine the feasibility of industrial processing of waste nylon, new and recycled polyamide 6 chips with the blend ratio of 100/0 , 75/25 , 50/50 , 25/75 and 0/100 were first dried and then melt spun at the take-up speed of 4000 m/min using a pilot-plant-melt spinning machine. Fiber structure including density, optical birefringence and thermal behavior, and physical properties including linear density, tensile properties and shrinkage of filament yarn samples, were measured and evaluated. Results showed that viscosity and molecular weight of samples having recycled poly amide 6 (PA6) displayed higher loss compared to the new PA6 after melt spinning process. Birefringence of recycled PA6 as-spun yarns was lower than that of new PA6. In general, noticeable differences were not seen between the fiber structure and tensile properties of new and recycled samples.
