Nylon webbing and polyester webbing dyeing technology and process
Dyeing technology by material:
1. Polyester webbing
Polyester fiber characteristics (fine)–hot melt dyeing, high temperature and high pressure dyeing–selected dyes–disperse dyes–temperature–(hot melt dyeing) around 190 degrees Celsius–(high temperature and high pressure dyeing) around 130 degrees Celsius.
2. Nylon webbing (protein products)
Nylon webbing fiber characteristics (with reactive functional groups)–steaming technology–selected dyes–(weak) acid dyes–temperature–about 100 degrees Celsius.
3. Finished cotton webbing (cellulose fiber)
Fundamental technology and process of dyeing workshop
1. Polyester fiber
Into the belt–before washing–before drying–coloring tank–pre-baking (infrared)–high temperature baking–after washing (recovery cleaning)–after drying–off the belt. Nylon webbing and polyester webbing dyeing technology and process
The effect of infrared pre-baking:
The dye molecules begin to attach to the fibers, preventing the appearance of doubts such as color blooms.
The effect of high temperature baking:
Make the dye molecules fully enter the interior of the fiber, and complete the process of dyeing the fiber with the dye.
Restorative cleaning effect:
Make the remaining dye molecules decompose to ensure the color fastness of the product.
2. Nylon webbing fiber
Into the belt–coloring tank–hot steam steaming–after washing–after drying–off the belt
The effect of steaming:
Make the acid dye molecules fully react with the corresponding functional groups in the fiber to complete the process of dyeing the fiber with the acid dye.
The effect of washing:
Remove unreacted dye molecules to ensure product color fastness, etc.
