Modeling of liquid rise in twisted yarns

Evaporation coefficient determination during the capillary rise

“…The majority of the wicking activity in capillary flow through textile fabrics is caused by the composed yarns. [3][4][5] As a result, a lot of research has been done to understand how wicking behaves in textile systems.…”

“…The majority of the wicking activity in capillary flow through textile fabrics is caused by the composed yarns. 3–5 As a result, a lot of research has been done to understand how wicking behaves in textile systems. In the extensive research in this area, textile yarns were either treated as a porous material, 6–8 where the liquid flow in porous material can be modeled by Lucas-Washburn kinetics, 9,10 or as capillary tubes.…”

“…In the extensive research in this area, textile yarns were either treated as a porous material, 6–8 where the liquid flow in porous material can be modeled by Lucas-Washburn kinetics, 9,10 or as capillary tubes. 1,5,11–17 However, in the first scenario, the typical parameters, such as permeability, are difficult to measure and are always determined empirically. 18 Similar to the first scenario, fitting the experimental data yields information on the effective capillary tube radius, effective contact angle, etc.…”
