Within the framework of the bachelor’s thesis, we compared eleven different laminates, of which eight were two-layered and three three-layered. They are distinguished by their front side (knitwear or non-wovens), density, foam thickness, and special properties (higher air permeability or low-volatile organic compound). Depending on the different types of laminates, different laminating processes were used, such as hot melt, flame lamination, and powder laminating. The purpose of the bachelor’s thesis is to find which combination of the laminate structure is the most optimal for a car seat and with what laminating process it is made of. Measured properties of the laminates we analyzed are abrasion resistance from 1,000 turns to a maximum of 36,000 turns, fire resistance to second mark or to the first mark, water vapor transmission – the lowest value 59.17 gm-²h-1 and maximum value 89.35 gm-²h-1, air permeability – from 0.901 m³/m²min to 21.181 m³/m²min, breaking force – from 39.27 N to 155.35 N, tensile displacement – from 40.29% to 152.02%, thermal conductivity – 0.082 Wm-1K-1 to 0.173 W m-1K-1, layering – in the longitudinal direction 3.34 N, maximum 9.88 N, and in the exact direction 3.29 N up to 8.39 N, surface mass – from 168 g/m² to 660 g/m² in thickness – between 2.165 mm at 10.323 mm. The investigated properties of the laminates are not influenced by the density and the foam thickness since the results are similar with all foam types. Non-woven textiles are not the best option to choose as the second component because they do not have good results at the abrasion resistance and tensile strength. Laminates with a knitted second compound have good abrasion resistance, high air permeability, and water vapor permeability. They are self-extinguishing to the first or the second mark, which means that they burn a maximum of 50 mm from the start of the ignition. Three-layered laminates have less of thermal conductivity and air-permeability than two-layered laminates.
