When dyeing a circular knitted fabric, the knitted fabric is generally dyed into a surface and then dyed into a dyeing machine. The positive and negative chromatic aberration generated at this time can be considered to be caused by the bleaching process and the dyeing process itself. Incomplete bleaching will cause positive and negative chromatic aberrations, which is the direct cause of the relationship between the dyeing results. Recently, due to the use of small bath ratio devices and the like, the bleaching process has gradually become more rational. However, in terms of effect, it is desirable to use a large amount of water treatment. Therefore, it is necessary to first confirm the quality of the bleaching treatment. When dyeing under conditions of poor dye permeability, a difference in permeability occurs between the surface in direct contact with the dye solution and the surface in contact with the dye solution, causing positive and negative chromatic aberration. This is related to the affinity between the dyes used, and the dyes which are easily dyed on the surface and the dyes which are not easily dyed on the surface are expressed by chromatic aberration. The difference in affinity can be solved by the correct choice of dyes, but in addition to the choice of dyes, the solubility of the dyes is reduced when the water quality is hard, resulting in surface dyeing or reduced solubility after adding alkali agents. phenomenon. The sudden color difference problem is generally related to the water quality of the water used. The choice of dyes is the key to solving these problems. However, in consideration of dyeing conditions, it is also an effective solution to use a metal chelating agent or a softener in a bath having a good penetration effect.
