Factors in the original raw material of imitation cotton webbing. First of all, it is necessary to pay attention to whether the yarns used are of the same batch, because the "oil" contained in different batches of yarns is not the same, such as blending, it will become a factor in the dyeing process; , Whether the original body has been pre-treated, the dyeing and coloring effect of the refined original body is very good, because the "oil" on the yarn after the treatment is removed, the dye can be directly contacted with the fiber and dyed, without protection.

In production, it is generally determined according to the thickness of the blank strip and the liquid rate. The higher the liquid rate of the blank strip, the higher the infrared pre-baking temperature. In actual production, the color difference between the front and back of the dyeing of the printed ribbon cannot be controlled only by the infrared pre-baking temperature, especially for sensitive colors such as coffee and dark green.
