Abstract

See full text

Fabric having warp and weft yarns where the filaments in the yarns freely move relatively to each other. The basis weight of the fabric is related to the thickness standard deviation of a stack of three identical fabrics deposited on each other. For basis weights greater than or equal to 40 g/m2 and less than 100 g/m2, the thickness standard deviation is less than or equal to 35 μm. For basis weights greater than or equal to 100 g/m2 and less than or equal to 160 g/m2, the thickness standard deviation is less than or equal to 50 μm. For basis weights greater than 160 g/m2 and less than or equal to 200 g/m2, the thickness standard deviation is less than or equal to 60 μm. For basis weights greater than 200 g/m2 and less than or equal to 400 g/m2, the thickness standard deviation is less than or equal to 90 μm.
