Ribbon is made of narrow width fabric or tubular fabric with various yarns as raw materials. In the 1930s, ribbon was produced by manual workshops, and the raw materials were cotton thread and twine. After the founding of the People's Republic of China, the raw materials for ribbon gradually developed to nylon, Vinylon, polyester, polypropylene, spandex, viscose, etc. The fabric structure has plain weave, twill, satin, jacquard, double layer, multi-layer, tubular and joint organization, forming three categories of machine weaving, knitting, knitting technology.

The dyeing principle and dyeing process of all kinds of dyes vary greatly due to the characteristics of dyes and fibers, which cannot be generalized, but in terms of their dyeing process, it can be roughly divided into three basic stages.

1. Adsorption, after the fiber is put into the dyeing bath, the dye first diffuses to the fiber surface, and then gradually transfers from the solution to the fiber surface, this process is called adsorption.

Over time, the concentration of dye on the fiber gradually increases, while the concentration of dye in the solution gradually decreases, and after a period of time, an equilibrium state is reached. The reverse process of adsorption is desorption, and both adsorption and desorption exist simultaneously in the dyeing process.

2. Diffusion: The dye adsorbed on the surface of the fiber diffuses into the fiber until the dye concentration in all parts of the fiber tends to be the same. Because the concentration of dye adsorbed on the fiber surface is greater than that in the fiber interior, the dye is diffused from the fiber surface to the interior.

At this point, the diffusion of the dye destroys the initial adsorption equilibrium, and the dye in the solution will be continuously adsorbed to the fiber surface, and the adsorption and desorption will reach the equilibrium again.

3. Fixation, is the process of the combination of dye and fiber, with different dyes and fibers, its combination is also different.
