Numerical Simulation Of Liquid Water Transport Behavior In Woven Structure

This article uses yarns and woven fabrics as carriers to study the simulation numerical simulation of the transmission behavior of liquid water in yarns of different radii,yarns with different spacing,woven fabrics with different spacing,and woven fabrics with different floating lengths.It observes the transmission behavior of liquid water in woven fabrics,analyzes the transmission mechanism of liquid water in woven fabrics,and seeks the most favorable conditions for the transmission of liquid water in woven fabrics,Exploring the controllability of liquid water transport behavior in woven fabrics,providing a theoretical basis for the research and design of moisture absorbing and fast drying clothing fabrics.In order to explore the influence of woven structure on the transfer behavior of liquid water,a more realistic yarn aggregation model and woven fabric model were established through modeling software.The yarn structure and fabric structure were changed,and corresponding physical models were constructed based on the structural parameters of the yarn and fabric.The spreading form and transfer distance of liquid water under different parameters were solved,and the factors affecting the transfer behavior of liquid water were analyzed,Explore the reasons for the high moisture absorption and quick drying performance of woven fabrics,as well as the transfer law of liquid water under different woven structural parameters.In order to investigate the effect of yarn fineness on liquid water transport behavior,3D yarn aggregation models with radii of r(radius),1/2r,1/4r,and 1/8r were constructed using simulation software.In order to investigate the influence of spacing on the transport behavior of liquid water,3D yarn aggregation models with spacing of 0,0.02r,0.04r,0.06r,0.08r,0.1r,and 3D woven fabric models with spacing of 0,0.1r,0.2r,0.3r,0.4r,0.5r,0.6r,and 0.7r were constructed.To investigate the effect of floating length on the transport behavior of liquid water,3D woven fabric models with floating length of 2,3,4,5,6,7,8,9,10,11,12,13,14,and 15 were constructed.Finally,the model was simulated and the transmission process of liquid water in different models was obtained.The diffusion distance and transport morphology of liquid water in the floating length direction,vertical floating length direction,and thickness direction of yarns and woven fabrics with different structures were simulated.Finally,a comparison was made with the diffusion of liquid water in actual testing of woven fabrics,and the authenticity and effectiveness of the numerical simulation were verified through experiments.This has important guiding significance for the research and development of moisture absorbing and fast drying fabrics.The results indicate that yarn radius,yarn spacing,and fabric structure can affect the transmission distance and spreading shape of liquid water in woven fabrics.The transmission of liquid water on woven fabrics has three typical forms:"ellipse","cross",and"unidirectional",as well as two transmission modes:unidirectional and bidirectional;The moisture absorption capacity of the yarn decreases with the decrease of the radius;Increasing the yarn spacing is beneficial for the transmission of liquid water in woven fabrics,but it is not always increasing.It is best to control the spacing conditions that are conducive to the transmission of liquid water at around 0.2r;Increasing the floating length is beneficial for the diffusion of liquid water,but it does not always increase.As the floating length increases,the diffusion distance will continue to decrease.It is best to control the floating length conditions that are conducive to the transmission of liquid water at around 4 or 1.
