Abstract:

In this paper nanofibres were formed from PVA solution with potato starch and a small amount of ethanol. Due to the previous study, it was determined that with the addition of ethanol (30 wt.%) in the solution, it is possible to form bicomponent PVA/cationic starch (75/25 wt.%) nanofibres. Preparation of a procedure using cationic starch was quite difficult, and therefore a high quantity of ethanol was also not desirable. In this study the influence of simple potato starch (which is used in the food industry) and a low quantity of ethanol on the formation of nanofibres was analysed. The results showed that with a 5 wt.% amount of potato starch it is impossible to form nanofibres by the electrospinning process. However, when a 5 wt.% amount of ethanol is added to the PVA solution, it was possible to form nonwoven material from nanofibres. It was confirmed that even a small amount of ethanol has a significant positive influence on the electrospinning process but not a positive influence on the nanofibres and web structure.
