To ensure that yarn required has been dyed with standard dyestuff and under standard condition/parameters, we insist that the suppliers of yarn send us with every lot the 
following test reports:

 

1. fastness, with regard to shade change and staining on Multifibre
   
   
2. Rubbing fastness – both dry rub and wet rub
   
   
3. Water fastness with regard to staining on multi fibre.
