Dyed fabric refers to colored fabrics that have undergone dyeing processing. Dyeing is the process of immersing a fabric in a dye solution to dye and fix the dye onto the fibers, thereby changing the color of the fabric. The definition of dyed fabrics can be explained in detail from the following aspects:
Dyeing method:
Immersion dyeing: Immerse textiles in a dye solution, and after a certain period of time, dye and fix the dye onto the fibers.
Roll dyeing: After the fabric is briefly immersed in the dye solution, it is rolled by a rolling mill to squeeze the dye solution into the gaps of the fabric tissue and remove excess dye solution. The fixation of the dye is completed in the subsequent steaming process.
Color fastness: The ability of dyed products to maintain their original color during use or subsequent processing.
Dyeing terminology:
Bath ratio: The ratio of the volume of dye solution to the mass of the dye.
Rolling rate: The percentage of dye mass carried on the fabric to the dry fabric mass.
Swimming movement: The phenomenon of dye moving along the direction of water evaporation during the drying process, which May cause color differences between the positive and negative surfaces.
Diffusion boundary layer: The area where the flow velocity of the dye solution decreases from the body to the fiber surface.
Directness: The performance of dyes on fibers.
Balance dyeing percentage: The percentage of dye adsorbed on the fiber to the total input when dyeing reaches equilibrium.
Uniform dyeing: The degree to which dye is evenly distributed on the surface of a fabric and within fibers.
These terms and techniques play an important role in the dyeing process, ensuring the dyeing effect and product quality.
