Abstract
The invention provides a method for solving the inner-outer layer chromatic aberration generation problem during the cheese or warp beam dyeing process. The method comprises the steps of pre-treating yarns or fabrics, modifying anions and dyeing. The anion modifying step comprises the operations of immersing yarns or fabrics in a modification liquid containing an anionic modifier and sodium carbonate; treating the yarns or the fabrics at 0-100 DEG C for 5 minutes to 48 hours, neutralizing and washing the yarns or the fabrics in water. Preferably, with the amount of the dye counted as 100%, the amount of the anionic modifier is 10-300% relative to the dye. According to the technical scheme of the invention, during the cheese or warp beam dyeing process, the inner and outer layers of yarns are uniformly dyed, and the chromatic aberration (delta E) between the inner and outer layers of the layers of yarns is not greater than 0.5. Therefore, the chromatic aberration (delta E) is much smaller than that of the conventional dyeing method.
Description
Technical Field
The invention relates to a method for solving the problem of color difference of an inner layer and an outer layer in a cheese or warp beam dyeing process, and belongs to the technical field of spinning.
Background
The occurrence of color difference between the inner layer and the outer layer in the dyeing process of cheese or warp beams is a technical problem which troubles dyeing workers for a long time. Because the dye has affinity and the dye solution flows in the front-back sequence, the color difference between the inner layer and the outer layer is inevitably caused, and a plurality of problems are brought to the subsequent processing. At present, this is mainly solved by several methods. First, by controlling process parameters, such as the rate of temperature rise. Secondly, a leveling agent is added. Thirdly, the yarns with larger color difference are selected. The first method and the second method have limited control on the color difference of the inner layer and the outer layer, and cannot meet the requirement of high-quality dyed yarns. The third method can solve the problem, but has high cost and large loss.
In summary, it is one of the problems to be solved in the art to provide a method for solving the color difference between the inner layer and the outer layer in the cheese or warp beam dyeing process.
