Abstract

The invention discloses a method for dyeing with a non-washing dispersing dye and is characterized by comprising the following steps of: fully mixing a microcapsule disperse dye with water, followed by cycling through a circulating pump and a dye vat, continuously extracting a single molecular dye, allowing the single molecular dye to contact with a fabric for dyeing, cutting out the cycling after dyeing, stopping supplying the dye into the dye vat, allowing the dye floating on the fiber to permeate into the fiber until the dye is completely permeated into the fiber, and directly drying. The invention has the following advantages: by the adoption of the above technology, residual dye molecules in the dye vat and single molecular dye molecules adsorbed on the fiber surface during the final phase of dyeing are all dispersed into the fiber by the chemical potential effect; trace adsorption dye (surface dyeing) remains on the surface of the fiber and the color fastness can be effectively improved by direct drying of the surface dyeing; in addition, with the application of the technology provided by the invention, dyeing procedures can be effectively minimized to realize clean dyeing.

Description

technical field [0001] The invention relates to a washing-free disperse dye dyeing method, in particular to a washing-free disperse dye dyeing method using microcapsule disperse dyes. Background technique [0002] Traditional disperse dyes are non-ionic dyes with strong hydrophobicity and low water solubility, which are mainly used in the printing and dyeing of polyester. In order to achieve a good dyeing effect, many auxiliary agents are needed when using the dye, which not only leaves residue in the fabric, but also requires a lot of washing processes, and is extremely unfriendly to the environment. [0003] Based on the above reasons, microcapsule disperse dyes have appeared. The dyes do not need to add additives during the dyeing process, and have good permeability, so the dyed fabrics have less floating color, and the process wastewater can be recycled, which greatly reduces pollution of the environment. However, the current microcapsule disperse dyeing still cannot a...
