Abstract:

In a previous publication [3] it was shown that the inclination angle of a fibre being imm-ersed and druwn out from a liquid reservoir (glycerol) influences the development of liquid instability, and consequently the formation of droplets on the fibre. In this paper, further investigation is presented, in which the phenomenon was explored by using another test liquid – polyvinylalcohol (PVA). Here, we verify that the behaviour of liquids on a fibre is influenced by its inclination angle. Furthermore, the results show that the behaviour of a PVA film on an inclined fibre differs from the behaviour of a glycerol film, despite the fact that test conditions were the same.
