The commonly used methods for fabric dyeing include rope dyeing, jet dyeing, roll dyeing, pad dyeing (not tie dyeing), and warp dyeing.  
Below is an introduction to warp dyeing suitable for long filament lightweight fabrics.  
The Beam Dyeing Machine (BEAM) rolls the fabric onto a porous drum and loads it into a pressure cooker. Using a high head, high flow professional chemical pump, the dye flow undergoes a positive and negative interaction in the system's circulation process, allowing the dye to completely penetrate the rolled fabric and be dyed in a high-temperature, high-pressure dyeing bath.  
The warp dyeing machine is suitable for sensitive fabrics that are prone to deformation, easy to roll edges, and easy to slip yarns.  
Before dyeing with a warp dyeing machine, the fabric should first be rolled onto the inner drum of the warp dyeing machine using a coiler.  
In order to increase the friction of the fabric and make it easier to roll, it is generally necessary to pass water during rolling. The amount of liquid in the fabric is adjusted by the pressure of the rolling mill and the speed of rolling.  
The quality of rolling has a significant impact on dyeing. When rolling, it is not necessarily the tighter or more tensioned the roll, the better the effect. When rolling, try to maintain a constant speed as much as possible.
During the dyeing process of nylon fabric with acidic dyes, the dye uptake rate is too fast, making it prone to dyeing and causing serious layer differences.
Especially sensitive colors such as khaki are the most difficult to con
