To calculate shrinkage, cut your
fabric into a square, record the measurements before washing in
the column marked Unwashed.
Wash & dry your fabrics using the product's care
instructions and record measurements.
Repeat the wash & dry until the measurement
stays constant (no change), This is typically 1 wash for
synthetics, 2-3 for natural or regenerated fibers.
Record the final length and width in the
calculator. |
