What are the ribbon dyeing process? Webbing can be used as a kind of clothing accessories products, but also as a kind of textiles. There are two main methods for the coloring of webbing. One is the most widely used dyeing (conventional dyeing), which is mainly to treat the webbing in a chemical dye solution. Another method is to use paint, which is made into tiny insoluble colored particles to adhere to the fabric (fiber raw material solution dyeing is not included here).
The color of the ribbon is very bright, and it is an ideal partner for many clothes and bags. However, in order to weave such a gorgeous ribbon, dyeing requires a high level of technology. Next, let's talk about how to dye the ribbon.
Ribbon dyeing process and process
Dyeing process determined by material:
1. Polyester
Characteristics of polyester fiber (dense)--hot melt dyeing, high temperature and high pressure dyeing--selected dyes--disperse dyes--temperature--(hot melt dyeing) about 190 degrees Celsius--(high temperature and high pressure dyeing) about 130 degrees Celsius
2. Nylon (protein product)
Nylon fiber characteristics (with reactive functional groups) - steaming process - selected dyes - (weak) acid dyes - temperature - about 100 degrees Celsius.
3. Cotton products (cellulose fibers)
The basic 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 (reduction cleaning)--after drying--off the belt.
The role of infrared pre-baking: the dye molecules are initially attached to the fiber to prevent the appearance of color flowers and other problems.
The function of high temperature baking: Make the dye molecules fully enter the fiber, and complete the process of dyeing the fiber.
The function of reduction cleaning: to decompose the excess dye molecules to ensure the color fastness of the product. 2. Nylon fiber
Into the belt--coloring tank--hot steam steaming--after washing--after drying--off the belt
The function 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 function of washing: remove unreacted dye molecules, and ensure the color fastness of webbing, ribbons and other products.
