A special design for the multi jets electrospinning system is presented. In this work, a 6 (g/ml) % polyethylene oxide (PEO) water solution was electrified and pushed by air pressure through a spinneret. The spinnerets were built-up with needles with a regular hexagon distribution and each 3 needles have been designed as a regular triangle distribution. The outside needles modified the electrical field to uniform the electrical field strength on the inside nozzles and restrict the path of the inside jets. A coaxial iron ring was used in order to uniform the electrical field strength on the outside nozzles and restrict the collection area. In this paper, a 7 cm diameter ring was used in the 7 needles system, a 9 cm diameter ring was used in the 19 needles system and a 11cm diameter iron ring was used in the 37 needles system test. The results demonstrated that the special design setup can produce uniform nanoscale fibres and the spinning process is insensitive with the atmosphere disturbance. The distribution of needles shows a possibility design for improving the production rate of nanofibres manufacturing.
