The causes and solutions of common dyeing problems are briefly discussed

1. There is color difference around the blind hole in the seam of dyeing products. Reason: The cleaning after oxidation is not thorough, and the sulfuric acid volume is slowly released outward during dyeing, which causes the PH of the local dyeing solution to change. Treatment method: Strengthen the ...
