Yes, and we should not be surprised: all natural fabrics shrink during washing, reducing, even if only slightly, the measurements.
In the case of sheets , it is a good idea to buy them a little larger, so as not to end up with bedding that is too small to cover our mattress. For pure cotton fabrics that do not include synthetic fibers, it is normal to have up to 4-5% shrinkage after the first wash. This loss is physiological and cannot be completely eliminated. In fact, we suggest that you look at it from a positive perspective since it confirms that the garment is actually made from a pure cotton fabric and does not contain other fibers of synthetic origin.
Thanks to the precious workmanship, Dalfilo sheets shrink up to approximately 3% after the first wash.
