Abstract

The invention discloses a synthetic fiber dyeing dispersion dye microcapsule and a preparation method thereof and relates to the technical field of microcapsules. The microcapsule comprises a dispersion dye, a wall material and a dispersant, wherein the wall material is prepared from N-hydroxyethyl acrylamide, N-isopropyl acrylamide and carboxymethyl-beta-cyclodextrin; the dispersant consists of PEG-60 hydrogenated castor oil and sodium polyaspartate. The microcapsule disclosed by the invention is solid in structure, good in mechanical strength and thermal resistance stability, no extra dyeingaid is needed when a synthetic fiber is dyed, and water washing is not needed after dyeing; wastewater generated after dyeing is low in treatment difficulty, the microcapsule in the wastewater can beremoved through standing and filtration, and the microcapsule can be also recycled.

Description

Technical field: [0001] The invention relates to the technical field of microcapsules, in particular to a disperse dye microcapsule for synthetic fiber dyeing and a preparation method thereof. Background technique: [0002] Disperse dyes are non-ionic dyes with strong hydrophobicity and low water solubility. Due to the extremely low solubility of disperse dyes in water, traditional disperse dyes are dyed with the help of a variety of auxiliary agents, such as compounds such as blooming agents and solubilizers, to disperse the disperse dyes in the dyeing medium water as uniformly as possible, and then Then dye the dyed object under appropriate temperature and pressure conditions. After dyeing, due to the presence of auxiliary agents, a considerable amount of dye remains in the dyeing wastewater, resulting in a large amount of COD, BOD and serious chroma pollution loads in the dyeing wastewater. Residual dyes are very finely dispersed and stable in wastewater, so it is diffi...
