How is webbing dyed? Which kind of webbing is woven first and then dyed?

Dyeing process determined by material [1] :

"Polyester"

Characteristics of polyester webbing fibers (dense)- 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)

Characteristics of nylon fibers (with reactive functional groups)- Steam distillation process - Selected dye -(weak) acid dye - Temperature - around 100 degrees Celsius.

3. Cotton products (cellulose fibers)

The basic processes and procedures of the dyeing workshop

Polyester fiber

Into the belt - water - before drying, coloring trough, preliminary drying (infrared), high temperature baking, after washing cleaning (reduction), after drying, belt.

The function of infrared pre-baking:

Dye molecules initially adhere to the fibers to prevent the occurrence of problems such as color streaks.

The function of high-temperature baking:

Enable the dye molecules to fully enter the interior of the fiber to complete the process of dyeing the fiber with the dye.

The function of restoration cleaning:

This enables the decomposition of excess dye molecules to ensure the color fastness of the product.

2. Nylon fiber

Enter the tape - coloring tank - Steam with hot steam - then wash with water - then dry - drop the tape

The function of steaming:

Enable the acid dye molecules to fully react with the corresponding functional groups in the fibers to complete the process of acid dye dyeing the fibers.

The function of water washing:

Remove the dye molecules that have not reacted completely to ensure the color fastness of the product, etc.
