The traditional dyeing process of the fabric can be divided into dip dyeing and pad dyeing according to different contact modes of dye and fabric, wherein the dip dyeing is a dyeing method for soaking a fabric to be dyed in a dyeing solution and uniformly dyeing the textile by the dye solution circulation and the relative motion of the fabric to be dyed, and the dye and the fabric can be circulated simultaneously or singly during the dip dyeing; the pad dyeing is that after the open width fabric is dipped in the dye liquor for a short time, the fabric is rolled by a press roll, the dye liquor is squeezed into the fiber and the gaps of the fabric tissue, the redundant dye liquor is removed, the dye is uniformly distributed on the fabric, and the dye is diffused and fixed on the fiber by the fabric after the dye is dipped and rolled by steaming or baking and the like. But the traditional dyeing process has the following defects: the traditional dyeing process has the advantages of large ordering amount, large color range, large water consumption, large consumption of steam and the like, large difference of matching property from color matching to dyeing, more dependency on the level of a master worker, environmental friendliness, high cost and low efficiency; the advantages are that: wide color gamut, good dyeing uniformity and high depth and hue.
However, in the current market, all the pure color printing realized by digital printing is based on the printing mode of a digital printing machine, and multiple colors are printed in a dot-positioning mode to realize the pure color under the visual effect, and the printing mode has the big problems that the printed pure color fabric has a dot-shaped granular sense visually, the caused dots are rough, the color hue and the saturation are not enough, the depth and the ink quantity are not enough, the color consistency is not ideal, and the method has the defects that the industrial, large-block, high-speed and long-time pure color block printing cannot be realized.
In view of this, how to overcome the disadvantages that the traditional dyeing process is not environment-friendly, has high cost and low efficiency when pure color dyeing is performed, and digital pure color printing has the disadvantages of point-like granular feeling, low color precision and the like becomes the subject to be researched and solved by the invention.
