Influence of the polyamide type and fibre diameter on the wicking height in nanofibrous structures

Due to the high porosity of nanofibrous structures, it is difficult to measure the hydrofilicity of the material with contact angle measurements. Therefore, a new method to examine the wicking behaviour of the structures is developed. This method is used on several structures, which differ in fibre diameter and polyamide type. The structures with the thickest nanofibres have the highest wicking rates. For different polyamide types, the capillary forces establish the wicking behaviour in the initial phase. Further in the process, it is determined by the capillary forces and the water absorption capacity of the bulk phase.
