When designing garments, comfort properties are an essential aspect of this design. For massaging cosmetotextiles, the comfort characteristics must suit all fabric specifics that give the massaging effect of the product. Weft knitted fabrics with 3D surface geometry have shown a good potential to be used in cosmetotextiles with massaging effects. The surface geometry can reach high complexity and influence the fabric properties. The paper studies the comfort properties of knitted fabrics with 3D surface geometry and follows the way the fabric structure control the fabric behaviour with regard to comfort characteristics – air, vapour and water permeability and thermal resistance
