The reasons:
 
① The sizing agent on the gray fabric is not washed clean,and also not washed clean after dyeing, there is still surface active agent on the fabric.
 
② The amount of water repellent agent is too little, the rate of absorption is low, and the speed of dyeing machine is rapidly.
 
③ The gray fabric is not completely dry.
 
④ The curing temperature is too low, reduce the water repellent agent crosslinking.
 
The prevention method:
 
① Washing the gray fabric completely, No impurity.
 
② Increase the water repellent agent, use different absorption rate for different fabric, the speed of machine should be less than 24m/min.
 
③ Process the water repellent finishing after dyeing, determine the suitable technology.
