ABSTRACT: Here we come up with the novel idea of production quality management that will be based on the correlation of data on-line system with inputs of materials and spinning conditions and output information of nano fibrous layer. This paper demonstrates application of optical monitoring on NanospiderTM, technology and has wider impact on understanding the process on wire with moving carriage than fiber diameter relation only, unlike the stationary needle process. It concerns to statistical behavior of the process with other unknown parameters, like number droplets and spinning jets per unit length of wire, direction of jets, droplet size and geometry, droplet lifetime, stability and way of consumption, wire vibrations etc. We also designed the illuminating system according to further image analysis presented as signal in data series. Here we have come out from this empirical knowledge and we used computer visualization for process analyzing. The basic idea was the detection of the stable parts and the raising jets of fibers.
