Disperse dye - Wikipedia
WEBDisperse dye is a category of synthetic dye intended for polyester and related hydrophobic fibers. Disperse dyes are polar molecules containing anthraquinone or azo groups. It is estimated that 85% of disperse dyes are azos or anthraquinone dyes.

WEBMar 6, 2021 · Disperse dyes are used for dyeing man made cellulose ester and synthetic fibres specially acetate and polyester fibres and sometimes nylon and acrylic fibres. Carrier or dispersing agents are required for dyeing with disperse dyes. Disperse dyes have fair to good light fastness with rating about 4-5.

WEBNov 16, 2023 · Disperse dyes, which are organic coloring compounds that lack ionizing groups and possess low water solubility, are ideal for dyeing hydrophobic textile mills via colloid dispersion. This distinct class of dyestuff, suitable for synthetic fibers like polyesters, acetates, and polyamides, earns its name from its non-soluble, non-ionic nature ...

WEBJan 1, 2011 · The growth of disperse dyes is closely related to the growth of polyethylene terephthalate (PET) and to the development of two new fibres which can be disperse-dyed: firstly, a new polyester, polytrimethylene terephthalate (PTT), known as Corterra®, developed by Shell and licensed by KoSa; and secondly, Nature Works polylactic acid …
Disperse Dyeing - an overview | ScienceDirect Topics
WEBDisperse dyeing of manmade fibres follows a solid–solid interaction where a solid dye is solubilised in another solid fibre phase and in all cases the dye forms no chemical bonds with fibre rather is retained by H-bonds and Van der Waals forces, except reactive disperse dyes which react only with nylon.

WEBJun 30, 2020 · The disperse dyes are organic colors that are less soluble in water and are widely applied to hydrophobic fibers such as polyester fibers where the dispersed dyes literally dissolve and produce the desired color [ 2 ].
WEBDisperse dyes are often substituted azo, anthraquinone or diphenylamine compounds which are non-ionic and contain no water solubilising groups. The dye particles are thus held in dispersion by the surface-active agent and the dyes themselves are called disperse dyes. They are marketed in the fo rm of either an easily disper sible powder or a ...
