The material classification
Polyester fiber characteristics (density) -- thermosol dyeing, high temperature high pressure dyeing method, chooses the dye, disperse dye, temperature - around 190 degrees Celsius (thermosol dyeing) method (high temperature high pressure dyeing) around 130 degrees Celsius.
2. Nylon (protein products)
Nylon fiber characteristics (reactive functional groups) - steam - steaming process - selected dyes - (weak) acid dyes - temperature - about 100 degrees Celsius.
3. Cotton products (cellulose fiber)
1. Dacron fibre
Into the belt - water - before drying, coloring trough, preliminary drying (infrared), high temperature baking, after washing cleaning (reduction), after drying, belt.
The effect of infrared prebake: the dye molecules are initially attached to the fiber, preventing the appearance of color flowers and other problems.
The effect of high temperature baking: make the dye molecules fully enter into the fiber and finish the dyeing process.
The function of reducing cleaning: to decompose the extra dye molecules to ensure the color fastness of the product.
2. Nylon fibre
In the belt -- the upper color slot -- the hot steam is steaming -- then the water is washed -- then dried -- falling
The effect of evaporation: to make the acidic dye molecules react with the corresponding functional groups in the fiber to complete the process of dyeing the fibers in the acid dyes.
Washing effect: remove the dye molecules that do not react completely, guarantee the color fastness of ribbon, ribbon and other products.
