Embodiment 1

[0060] like Figure 1 to Figure 7 Shown, the preparation method of a kind of environment-friendly type high fastness disperse navy blue dye composition of the present invention, this method is applicable to above-mentioned environment-friendly type high fastness disperse navy blue dye composition, this dye composition adopts following steps to prepare Pick:

[0061] S1: After mixing component A, component B, component C, filling aid and a certain proportion of water, put them into a grinder to grind and disperse to obtain a mixed solution;

[0062] S2: Start the motor 7 in the spray dryer, the motor 7 drives the No. 1 winding wheel 9 to rotate forward and reverse intermittently, so that the cleaning ring 11 reciprocates up and down in the housing 1, and the steel wire layer 12 scrapes and rubs the inner wall of the housing 1, Scrape off the dye remaining on the inner wall of the housing 1 in the previous work;

[0063] S3: Connect the air inlet 2 to an external hot air sourc...

Embodiment 2

[0071] like Figure 8 As shown in Comparative Example 1, as another embodiment of the present invention, the cross-sectional shape of the No. 2 winding wheel 13 is gourd-shaped, and the No. 2 winding wheel 13 is eccentrically arranged with respect to its central axis; The section shape of No. winding wheel 13 is set to gourd shape, can make No. 2 winding wheel 13 in the process of rotation, can drive No. 2 connecting rope 14 to vibrate, cooperates water to drench from No. 2 connecting rope 14 surfaces, thereby improves To the cleaning effect of No. 2 connecting rope 14.

[0072] Offer a chute 28 in the No. 2 winding wheel 13; a counterweight ball 29 is slidably connected in the chute 28; Free sliding, so that the second winding wheel 13 is in the process of rotation, the counterweight ball 29 will slide from one end of the chute 28 to the other end under the effect of its own gravity, and then hit the inner wall of the chute 28, driving the second coil. The winding wheel 13 ...

Abstract

The invention belongs to the technical field of fine chemical engineering, and particularly relates to an environment-friendly high-fastness disperse navy blue dye composition and a preparation method thereof. The dye composition comprises, by weight, 20-42 parts of a component A, 29-51 parts of a component B, 46-65 parts of a component C, and 70-210 parts of a filling aid. The dye composition does not contain forbidden aromatic amines, sensitization and carcinogenic dyes, chlorophenol, organochlorine carriers, quinoline and other components harmful to human health, meets the OEKO-TEX Standard 100 indexes of textiles, has high environmental protection property, improves the compatibility of the dyes and improves the exhaustion rate and utilization rate of the dyes through compounding and addition of the dyes with different structures, meanwhile, the dyeing or printing soaping residual liquid is clear, the treatment difficulty of printing and dyeing wastewater is reduced, and the dye is good in lifting power and excellent in water soaking, sublimation and soaping color fastness.

Description

technical field [0001] The invention belongs to the technical field of fine chemicals, in particular to an environment-friendly high-fastness dispersed navy blue dye composition and a preparation method thereof. Background technique [0002] Disperse dyes are the most important and main category in the dye industry. They do not contain strong water-soluble groups and are a type of non-ionic dyes that are dyed in a dispersed state during the dyeing process. Its particle fineness is required to be around 1 μm. After the raw dyes are made, post-processing, including crystal form stabilization, grinding with dispersants and other commercial treatments, can be used to make commercial dyes. It is mainly used for printing and dyeing of polyester and its blended fabrics, and can also be used for printing and dyeing of synthetic fibers such as acetate fiber, nylon, polypropylene fiber, polyvinyl chloride, and acrylic fiber. [0003] Some technical schemes about disperse dyes have a...
