The development of the research techniques of structure and properties of composite textile materials when interacting with viscous fractions of hydrocarbon compounds

Abstract

The article presents the application results of the method of acoustic emission for quantitative assessment of the process of coating of porous textile materials. Under the influence of capillary pressure the wetting part of a viscous liquid can be absorbed by porous materials of clothes and also it can change its properties. To assess the adequacy of the use of the alternative method of acoustic emission in the assigned task the experimental studies based on the acoustic emission technique and the weight method were carried out. In the basis of the experimental equipment a special laboratory complex was used, which has a multichannel system for recording acoustic signals while monitoring mass variations of the samples in-parallel. On the basis of this method a number of experimental studies of modern textiles of different nature and structure was carried out, which allowed assessing the changes in their structure when interacting with viscous fractions of hydrocarbon compounds and establishing a connection with variation of their functional properties for the application conditions in the protective clothes for industrial purpose.
