What are disperse dyes? What solvent is used for disperse dyes? Disperse dyes have small molecules and lack water-soluble groups in their structure. With the help of dispersing agents, they are uniformly dispersed in the dye solution for dyeing. They can dye polyester fibers, acetate fibers, and polyamide fibers, and are a special dye for polyester.
What are disperse dyes? What solvent is used for disperse dyes? Disperse dyes have small molecules and lack water-soluble groups in their structure. They are uniformly dispersed in the dye solution with the help of dispersing agents for dyeing. They can dye polyester fibers, acetate fibers, and polyamide fibers, and are dedicated dyes for polyester.
Disperse dyes can be broadly classified into disperse orange, disperse blue, disperse yellow, and disperse red. Several different disperse dyes can be combined in certain proportions to obtain disperse black, disperse green, disperse purple, and other disperse dyes.
In the commercial processing of disperse dyes, in order to enable the commercial dyes to quickly disperse in water to form a uniform and stable colloidal suspension, the dye particle size must reach about 1 micron. Dispersing agents and wetting agents are added during the sand grinding process. The post-processing of disperse dyes generally consists of sand grinding, seasoning, spray drying, and packaging. Many auxiliaries are used in the post-processing, such as lignin, MF, anti-settling agent (SOS), anti-dusting agent, dispersing agent NNO, and sodium sulfate is also added to adjust the intensity.
Disperse dyes are one of the most important and major categories in the dye industry. The three giants in the domestic production of disperse dyes are Zhejiang Longsheng Group, Zhejiang Runtian Chemical Group, and Zhejiang JiHua Group Co., Ltd. These three companies occupy a dominant position in the domestic disperse dye market, with each producing over 100,000 tons.
A type of non-ionic dye that does not contain strong water-soluble groups and is in a dispersed state during dyeing. Its particle size is required to be around 1μm. After the original dye is obtained, it needs to undergo post-processing, including crystal stability and grinding with dispersing agents, etc., before it can be made into a commercial dye. It is mainly used for dyeing polyester and its blended fabrics. It can also be used for dyeing synthetic fibers such as acetate fiber, nylon, polypropylene, chlorinated fiber, and acrylic fiber.
