Nowadays, polymer Nano fibers have been extensively used in the industrial and research fields. At the present, products such as filters, wound healing, vessels, batteries, and many other types of products which are manufactured from polymeric Nano fibers are find in the markets. There are various methods for the polymeric nanofibers production. In this research, poly amide 66 nano fibers were produced by forcespinning®. In this way, the effect of different parameters such as concentrations of polymer solution, chamber temperature, nozzle diameter and rotation speed (RPM) were investigated. In this research we find out the average diameter PA66 nanofiber it was within nano scale. Also the production time was during few second and the speed flow rate was 6.5 meter over second.
