Abstract

The most important properties of the majority of knitted fabrics are good stretchability and elasticity, and thus the resulting freedom of movement. They are able to adopt themselves to the body shape of the wearer and have good air permeability, offering high standard of wear comfort. In this paper, the influence of structural properties and characteristics of fiber on the thermal properties, air and water vapor permeability, as well on the physical-mechanical properties of single jersey knitted fabrics were investigated. Single jersey knitted fabrics are made of 100% wool, 50/50% acryl/cotton, and 100% acryl yarn. The thermal properties of knitted fabrics were measured by method of D-r Boc. Correlation and regression analysis were used for data processing. The results indicate that characteristics of the fibres have significant influence on the the physical-mechanical and thermal properties, while structural characteristics have significant influence on the air and water vapor permeability. Knitted fabrics made of 100%wool have the highest thermal resistance and warmer feeling and touch due to the lower thermal absortivity value, while knitted fabrics of 50/50% acryl/cotton gave a séance of coolness. On the other hand, density and cover factor have most important influence on air and water vapor permeability Key words: single jersey, thermo-physiological comfort, air permeability, water vapour permeability
