The leuco acid dyeing method is rarely adopted due to the great difficulty in process control. The current common suspension dyeing method is that unreduced dye particles and a diffusant are ground and mixed to prepare highly dispersed suspension, a fabric is padded in the suspension and then is uniformly attached to a fiber, then the dye is directly and rapidly reduced on the fabric by using a reducing solution, and finally the dye is fixed on the fiber by oxidation; the leuco dyeing method is that the dye is reduced into leuco dye liquor in advance, and the leuco dye liquor is passed through several times of padding to complete adsorption and diffusion of fibre, then passed through the processes of oxidation and soap boiling, and fixed on the fibre.
At present, vat dye continuous open width dyeing generally adopts a vat dye suspension dyeing process, which generally comprises the following steps: 1, feeding a product to be dyed into cloth; 2, padding a suspension dye liquor; 3, drying; 4, padding and reducing the color fixing solution; 5, steaming; 6, washing with water and oxidizing; 7, soap boiling; 8, washing with water; 9, drying; and 10, cooling and cropping. As can be seen from the above, the whole process flow is long, the processes are multiple, and the probability of the occurrence of the defective cloth is correspondingly high. If the leuco dyeing method is adopted in the continuous open-width dyeing of vat dyes, the process flow is obviously shortened because the dyes are directly dyed on the fibers without a 'bottoming and drying process' after being reduced into leuco bodies in advance.
