Abstract :The main idea of this work is to study the effect of knitted fabric characteristics on capillary rise and sorption ability by combining experimental and mathematical approaches. An experimental device performing the vertical suspension of fabric-liquid surface and permitting the penetration of water molecules through the tested samples is used. Experimental values of vertical wicking were gravimetrically measured using an electronic microbalance, and theoretically studied using the linear logarithmic model (LLM). The results show that the theoretical predictions are in reasonable agreement with the experimental data with high correlation coefficients values. It is also demonstrated that capillary rise kinetics are influenced by knitted fabric features, such as composition, knit structure, type of yarn and of couliering depth value. Water sorption kinetics of cotton fabrics have also been studied and modeled by using mass measurements of the water absorbed by the textile and the LLM equation in order to interpret the experimental data in terms of sorption ability.
