Test method of shrinkage rate:

1. Sampling: take a certain length of fabric, measure the length and width, and make a record;

2. Steps: the fabric into water, rub with the hand, make the fabric completely drenched, soak for 15 minutes, to water pressure (cannot twist, ground), opened flat, dry, measure the length and width.

3. Calculate the shrinkage rate according to the formula.

                               Length before shrinkage - length after shrinkage

The rate of shrinkage=   ——————————————————————x 100%

                                             Length before shrinkage

The dimensions of the warp and weft direction of different fabrics are measured, including the shrunk and controlled fabrics, the figures are accurate when measured, and the dimensions are filled into the table.

This is an easy way to do it. For careful testing, please use Wascator Automatic Shrinkage Tester to measure.
