DISCRETE THREE-DIMENSIONAL MODEL OF MOISTURE SPREADING IN TEXTILE MATERIALS

摘要

In this paper were developed methods of determining the period of passing the liquid through textile materials by modelling its discrete structure. The work is based on experimental data of the structure of materials and experiments on the passing of fluid through elementary samples. These data were obtained on the basis of a brightness of colour liquid that passes through the sample of material. Dependence to determine the concentration of the liquid in the volume model of the textile material was proposed. Discrete distributions are obtained, which show the presence of fluid in the various points of the material in the longitudinal, transverse direction and depth. It revealed the border, which reaches the fluid at different times. Discrete points have been replaced by a continuous curve. An analytical function of changing of wetted zone was built. The results allow predicting the term of full wetting of materials and forecasting the term of comfort use of products, to define the parameters of the material for a certain period of work.
