Flat woven light-weight fabrics and their use for the production of seat covers

Method of constructing a flat woven light-weight fabric, comprising the following steps:

• i) selecting a flat woven heavy-weight fabric having a weight of 260 to 340 g/m2, said heavy-weight fabric showing a decorative pattern;
• ii) determining the warp yarn titer, the weft yarn titer, the warp density and the weft density of said heavy-weight fabric and entering these parameters in a weave design program;
• iii) modelling different weave designs by systematically decreasing at least one parameter selected from the the warp yarn titer, the weft yarn titer, the warp density and the weft density of said heavy-weight fabric in the weave design program;
• iv) comparing each of the weave designs obtained in step iii) with the decorative pattern of the heavy-weight fabric and selecting that weave design which shows the same decorative pattern as that of the heavy-weight fabric and which has a weight being at least 20% lower than that of the heavy-weight fabric;
• and
• v) weaving a fabric according to the weave design selected in step iv) thereby obtaining a light-weight fabric having the same decorative pattern as the heavy-weight fabric.
