Abstract

The invention provides a bobbin dyeing method to prevent dyeing condensation of active turquoise blue dyestuff. The bobbing dyeing method helps implement uniform dyeing effectively and simply and alsoprevents color spots and patterns caused by dyestuff condensation. Compared with existing utilization of cylindrical bobbins, the bobbin dyeing method applies directly modifications to the structureand helps form spindle-shaped bobbins by performing slack spooling on yarns under specific parameters; the spindle-shaped bobbins help effectively prevent dyestuff condensation and avoid color spots and patterns for dyed bobbins; the bobbin dyeing method is simple and feasible; corresponding pre-dyeing treatment and post-dyeing treatment are performed on the spindle-shaped bobbins; a dyeing process for spindle-shaped bobbins is utilized. Compared with existing bobbin dyeing methods, the bobbin dyeing method herein helps prevent active turquoise blue dyestuff from condensing on bobbins and effectively prevent color spots and patterns from occurring during bobbin dyeing.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a cheese dyeing method which avoids the dyeing condensation of reactive emerald blue dye, and prevents the dyed cheese from appearing in color spots, color spots and color spots. Background technique [0002] Reactive turquoise blue dye has bright color and unique hue. Compared with the price of common brilliant blue dyes, reactive turquoise blue dye is cheap, and when it is matched with other reactive dyes, the shade is irreplaceable, so it is widely used in cellulose fiber dyeing. However, because the reactive turquoise dye is based on the copper phthalocyanine structure, its molecular structure is a ring-shaped three-dimensional, the molecular weight is large, and the dye is easily absorbed by the fiber. But at the same time, its diffusivity is relatively poor, it is difficult to penetrate into the inside of the cellulose fiber, and it is easy to cause uneven dyei...
