Interpretive Summary: Three dimensional fibrous fabrics are important textile materials. These functional fabrics offer a wide range of production technologies, and have the ability to control moisture, and offer comfort next to skin. This paper discussses liquid movement with the help of computer simulation and shows a relationship between fiber orientation and the wicking rate.

Technical Abstract: Liquid movement in 3-D fibrous materials is studied in this article by means of Monte Carlo simulation based on the Isling model with so-called Kawasaki kinetics. Computer simulation algorithms are then developed in accordance with the standard liquid wicking rate tests from both EDANA and INDA, and the simulation results provide information of liquid wicked into computer-generated fiber assemblies as a function of time. The work focuses mainly on the relationship between fiber orientation and the liquid wicking rate, while other geometrical parameters of the fiber mass remain fixed. Furthermore, this simulation also presents dynamic data of both liquid mass uptake and energy changes of the system. The results are in agreement with known experimental evidence.
