Different materials printing webbing dyeing technology and process
Dyeing technology with material resolution:
Polyester fiber characteristics (fine) - hot melt dyeing, high temperature and high pressure dyeing - selected dyes - disperse dyes - temperature - (hot melt dyeing) 190 degrees Celsius - (high temperature and high pressure method) 130 degrees Celsius.
2. Nylon (protein commodity)
Nylon fiber characteristics (with reactive functional groups) - steaming technology - selected dyes - (weak) acid dyes - temperature - 100 degrees Celsius.
3. Cotton finished (cellulose fiber)
The basic technology and process of dyeing workshop
1. Polyester fiber
Pre-Bake - Pre-Bake - Pre-Bake - Pre-Bake - Pre-Bake (Infrared) - High Temperature Bake - After Washing (Recovery and Cleaning) - After Drying - Falling.
Infrared pre-bake effect:
Dye molecules began to attach to the fiber, to prevent color and other problems presented.
High temperature baking effect:
So that the dye molecules into the fiber inside, the end of the dye dye on the process.
Restore the effect of cleaning:
So that the remaining dye molecules to break down to ensure that the color fastness of goods.
2. nylon fiber
Incoming - color tank - steam from the steam - after washing - after drying - with the band
So that the acid dye molecules with the fiber in the corresponding functional groups to respond to the end of acid dye dyeing process.
Remove the dye molecules that do not respond thoroughly, printing webbing and ensure the color fastness of the goods.
