Measure the wash swatch with shrinkage scale and derive the vertical and horizontal shrinkage.

We assign the shrinkage family in four groups.

 

GROUP                     TYPE                         %

 

A                                 VERTICAL                1 – 3%

B                                 VERTICAL                3.5 – 6.5%

C                                 HORIZONTAL          1 – 4.5%

D                                 HORIZONTAL          5 – 9%

 

So we make a report for each group and forward it to store so that it can issue fabric accordingly.
