In this study, the process of electrospinning was used on nanofiber yarn formation. The parameters in the study were flow rate and twist multiplier, which were discussed their effect on yarn formation. Further, a normal yarn was used as the core yarn, which was wrapped with nanofibers to form a new type of composite yarn. In this part of the experiment, the parameters were flow rate and collector width, which were discussed in terms of their effect on the yarn quality of nanofibrous composite yarn. The experiment result showed the diameter of the nanofiber was between 220 am to 260 nm. When the collector width was 5 mm, there was a high quality wrapping resulting in good yarn, with the nanofiber composite yarn having a strength of 3.25 (cN/dtex).
