Meaning and Definition
A type of dye that is not water-soluble in its application form and must be finely ground and dispersed in a liquid medium to color synthetic fibres.
In chemistry and textile manufacturing, a dye that is applied from an aqueous dispersion onto hydrophobic fibres like polyester or acetate, where the dye molecules dissolve into the fibre. More broadly, can refer to the process of using such dyes.
Dialectal Variation

No, they are generally ineffective on natural, hydrophilic fibres like cotton. Cotton requires dyes like reactive or direct dyes.
Primarily, it is a compound noun. However, it can be used in a hyphenated verb form ('to disperse-dye') in technical contexts, meaning to dye using disperse dyes.
Some disperse dyes, particularly certain azo dyes, can be allergenic or break down into harmful aromatic amines. Regulations strictly control which dyes can be used in apparel.
They are crucial for colouring the vast quantities of synthetic fibres (especially polyester) used globally in textiles, providing bright, durable colours that would otherwise be impossible to achieve.
A type of dye that is not water-soluble in its application form and must be finely ground and dispersed in a liquid medium to color synthetic fibres.
Disperse dye is usually technical, industrial in register.

Conceptual Metaphor
COLOR AS A PARTICULATE INVADER: The dye is conceptualised as an army of tiny particles that invade and occupy the synthetic fibre.
