What is the average process weight loss for denim wash garments?

The denim garments are washed after sewing complete, but do we know the process loss that happens in the denim washed garments that may have an effect on tearing strength?

Okay here I am sharing the percent loss of weight for different denim wash:-

In the left chart I have shown the process wise average weight loss that happens in denim wash and also over dyeing. So, be careful when you are washing the garments, because if you take low GSM fabric and apply a light wash on the garments then the tearing strength will be crossed the tolerable base line which will not be acceptable by anyone.

Please note - In the chart "Over Dyeing" process wise weight loss is mentioned only for Gray Fabric (PFD), The situation is dependable on very circumstances, like-

1) For Reactive dyeing- The Weight loss will be very minimum for RFD fabric,
2) For Pigment/Direct dyeing- The wright will be increased due to dye absorption to the RFD fabric,
3) For Enzyme wash- the average weight of the garment will be loosen but the total GSM will be increased due to shrinkage of the fabric.

Thanks for reading, & if you have any question please put it in the comment box.
