Nylon webbing (protein product)
Nylon webbing fiber characteristics (with reactive functional groups) - steaming technology - selected dyes - (weak) acid dyes - temperature - about 100 degrees Celsius.
Dyeing process: tape entry--pre-washing--pre-drying--coloring tank--pre-drying (infrared)--high temperature baking--post-washing (recovery and cleaning)--post-drying--dropping tape. Nylon webbing and polyester webbing dyeing technology and process

The effect of infrared pre-drying: the dye molecules begin to attach to the fiber, preventing the appearance of color flowers and other problems.
The effect of high-temperature baking: make the dye molecules fully enter the inside of the fiber, and complete the process of dyeing the fiber with the dye.
Restoration and cleaning effect: decompose the remaining dye molecules to ensure the color fastness of the product.
The effect of steaming: make the acid dye molecules fully react with the corresponding functional groups in the fiber, and complete the process of dyeing the fiber with the acid dye.
The effect of washing: remove the dye molecules that have not reacted thoroughly, ensure the color fastness of the product, etc.
