Air permeability and structural parameters of single jersey knitted fabric

Popis výsledku v původním jazyce

The main aim of our study is to investigate the influence of the basic structural parameters on the air permeability value of plain jersey knitted fabric. A specific experimental set of knitted fabrics was used for this purpose – the yarns of two materials (viscose and polyester) and two yarn counts (20 tex and 29.5 tex) were used, each of these four yarns was used to manufacture a set of plain jersey knitted fabric samples of several different densities. Altogether 22 different knitted samples were prepared and used for investigation the basic relationships between air permeability and the structural parameters of the knitted fabrics. Primary and secondary structural parameters such as density, thickness, planar weight or porosity were investigated. Porosity was calculated according to three different theoretical models. permeability decreases. As the porosity of the knitted fabric increases, its air permeability increases, with the value of air permeability reacting most sensitively to the porosity expressed as a proportion of the open area of the knitted fabric. The results also showed that the relationship between air permeability and porosity as well as the relationship between air permeability and planar weight are not completely linear. Linear relationship was found between the air permeability of the knitted fabric and the proportion of its porosity and planar weight.
