Due to the widespread applications of nanofibers, optimizing the production process of nanofibers produced from different polymers is under consideration in different sciences. For this reason, our research work has been focused on this topic either in order to optimize the electro spinning process in such a desired condition related to the end use applications. As we know, one of the functional areas of using these kinds of fibers related to medical prosthetics and medical scaffolds which are very sensitive in their fields. In this case, it’s essential for nanofibers being oriented and arranged particularly. In order to arrange these fibers in both longitudinal and transversal direction, various methods have been held from since now. Generally in medical science and especially for implantation of foot tendon cells, a transversal orientation and arrangement of nanofibers are being used more for producing various medical media. During this research, our attempts have been on choosing a new method used in fiber accumulation in order to control the fiber orientation and arrange them in a desired pattern. For this reason, a collector was designed comprising three different sections named as the control circuit, the command circuit and the collecting plate. Using this kind of collector with the aim of electro-magnetic field switching, the oriented accumulation of nanofibers was expected. A program was obtained using MATLAB programming software in order to determine how and when the switching happened in parallel and perpendicular wires of collecting plate. The switched current transferees through the control circuit and then is performed by the command circuit. It can be stated that the main operation done here is connecting the wires with the earth. The current is controlled by the circuit and switched in a desired time interval. By this function indeed, the magnetic field will be switched and the fiber aggregation position on the collecting plate might be controlled. During the nanofibers production and electromagnetic field switching, the nanofibers accumulated on the wire which has been connected to the earth. If all charges of nanofibers won’t be discharged, the accumulation of nanofibers on wires of the modified collector will continue alternatively on another wire which has been switched this time and connected to the earth. It should be mentioned that during the alternative electromagnetic field switching, the nanofibers would be undergone elongation in magnetic field. In this research also, another software program was designed using MATLAB software in which the forces produced through the magnetic field switching have been involved. This program can show the nanofibers directions of motions approximately. In the said program it can be available to change some of the electro-spinning variables. Moreover, paying attention to the modeled path could be possible to determine which variable provides the best answer. By the use of designed collector, electro-spinning samples were produced and compared with the modeled sample. The SEM images of produced nanofibers samples were provided and their related angular spectrum diagrams were obtained using a program obtained by MATLAB software. The results of SEM images and the angular spectrum diagrams showed that the considered model provided the desired fibers arrangement based on their applications. In addition it can be claimed that by this model, the condition and fiber path could be estimated before even sample production. This in turn saves the material, energy and time spent for experiments. Key words Nanofibers orientation, polycaprolactone, electro-spinning, motion path modeling, magnetic field switching
