The research aims to discover new materials adequate for footwear linings, considering the main functions which should be assured, such as: improving its appearance, increasing the comfort and durability of the footwear. Knitted fabrics represent a category of textiles which proof availability for such destinations, due to the wide product range given by various combinations of: geometry, shape, yarns and finishing. Several single jersey fabrics were produced using functional yarns like Coolpass, Coolmax, Outlast and Dri-Release in different stitch densities. This paper reports the study on the influence of yarn type, fabric tightness and finishing on the the behaviour of the knitted fabrics for footwear linings, throughout the properties: fabric extensibility, pilling, friction properties, initial elastic modulus. A comparative analysis between yarn type emphasizes the suitability of the designed fabrics for footwear linings.
