example 1

[0012] Example 1: The liquid disperse dye HGL dark blue 500Kg produced by Zhejiang Hangzhou Fulida Chemical Co., Ltd. was homogenized 5 times with a high-pressure homogenizer produced in Shanghai, filtered with a 1-micron membrane, and then filtered with a 0.5-micron membrane. Then add sodium polyacrylate thickener 15Kg, stir for 5 minutes, and leave it for 2 hours to obtain the ultrafine paste disperse dye deep blue HGL of particle diameter<0.5 micron.

example 2

[0013] Example 2: Liquid disperse dye red S-BL500Kg produced by Zhejiang Longsheng Dyestuff Chemical Co., Ltd., homogenized 4 times with a high-pressure homogenizer, filtered with a 1-micron membrane, and then filtered with a 0.5-micron membrane, and then added alginic acid Sodium 10Kg, stir for one hour with a high-speed beater. After standing for 2 hours, the ultrafine paste disperse dye red S-5BL with a particle size of <0.5 micron was obtained.

Abstract

The invention aims at providing an ultramicro pulpy disperse dye for terylene dyeing. The ultramicro pulpy disperse dye has the viscosity of more than 3000 cp (an NDJ-1 viscometer), is used for the terylene dyeing, has the advantages of no dust, no foam, no cohesion and sedimentation, no migration, pure color and luster, high color yield, greatly reduced dyeing usage amount and good color fastness without reduction clearing and soaping after the dyeing, multiply reduces the polluted water dyeing and the polluted water discharge, reduces the CODcr (Chemical Oxygen Demand) contained in polluted water and opens a new way for the clean production of printing and dyeing mills.

Description

Technical field: [0001] The invention relates to a kind of dye used for textile dyeing, a kind of 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 fibers. After a long t...
