Abstract

The invention discloses supermicro slurry dispersing dye for dyeing terylene. A formula of the supermicro slurry dispersing dye is as follows: 11 to 15 parts of dye, 2 to 4 parts of emulsifier, 3 to 5parts of thickening agent, and 22 to 43 parts of solvent. The supermicro slurry dispersing dye has no dust, no caking and no foam, has no dispersion problem, can protect the health, and can thoroughly solve the coagulation, precipitation and layering problems of the liquid dispersing dye.

Description

technical field [0001] The invention belongs to the technical field of disperse dyes, and in particular relates to an ultrafine slurry-like disperse dye used for polyester dyeing. Background technique [0002] Polyester dyeing is dyed with disperse dyes, light colors are dyed with low-temperature disperse dyes, medium-dark colors are dyed with medium-temperature and high-temperature disperse dyes, and the production process of low-temperature, medium-temperature, and high-temperature dyes is as follows: Production of disperse dye filter cake → ball milling , sanding → adding diffusing agent → spray drying → finished product, so that the particle size of the disperse dye produced by the process is about 2 microns. [0003] Polyester dyeing adopts a high temperature and high pressure dyeing method at about 130°C. Due to the tight structure of polyester fibers, the pores of the fibers increase at a temperature of about 130°C, and the dye enters the interior of the polyester fib...
