Statistical simulation of particle flow across nonwoven structure

Abstract

The paper investigates statistical simulations of particle flow across a nonwoven structure of polymer materials using the method of computer simulation of the model of particle filter. The main aim is to improve methods of manufacturing non-woven textiles. The idea is to use computing and visualization applications that capture and simulate the in-depth analysis of materials prior to production. The basic model is based on continuous one axial flow and is monitored depending on the steric configuration of the non-woven textile membrane and time. Polytetrafluoroethylene (PTFE) in the form of a nonwoven fabric was used in the simulation model, which in its structure contains pores that allow passage of water vapor through the structure and prevent the passage of the aqueous phase, thus creating a physical barrier to contaminating substances including water. In the area of textiles such structures have applications in the production of special medical textiles, construction of waterproof and windproof garments, special sportswear, which provides comfort because there is no condensation of sweat - vapor phase from the inside of the garment. Using modem multimedia technological platforms, it is possible to significantly reduce costs and to improve the manufacturing procedure. It is believed that soon these statistical simulations of particle flow will be used as a standard method of production.
