Care for Fabrics - washable fabrics

A fabric can be considered as washable if after washing dimensional stability (or a small fluctuation) and color fastness can be expected.

Few fabrics are washable especially if their composition is from a mix of different fibers; dimensional fluctuation due to humidity may vary according to the composition of the fabric.

The fluctuation usually mentioned are the following:
Synthetic fabrics : +/-  1% variation
Coton : 1 à 4 %
Linen : 5 à 7 %
Viscose : 3 à 5 %
Silk : 1 à 3 %.
