EXPERIMENTAL ASSESSMENT OF PERMEABILITY FOR DIFFERENT MULTILAYERED TEXTILE COVERINGS

Abstract

The aim of the paper was the research on the distribution of moisture through the mattress cover materials in real conditions and the variation of moisture accumulated by different test methods. In the analysis of moisture transfer processes through textiles it is necessary to distinguish between the transport of moisture in the form of vapor (molecule) and the liquid state (drop). Thus, several tests (permeability, drip, wetting) were used to highlight the way of sorption of multilayer knits for mattress covers. The purpose and novelty of the research is the use of multilayer textile supports from different and associated raw materials varied in the textile ensemble with the special destination, influencing differently the values of water vapour permeability and vaporization The results demonstrated the influence of raw material and the other specifications on vapour permeability and absorption capacity of multilayer knitwear. Textile coverings with polyester, bamboo and viscose in composition showed the highest permeability and low vaporization index. Future research will characterize the thermophysiological comfort of the investigated supports by other indices that characterize the functionality of the products.
