22503 High Concentration & High Temperature Leveling Agent

22503 High Concentration & High Temperature Leveling Agent

Short Description:

22503 is mainly composed of aromatic ester derivative.

It has excellent dispersity, solubilizing performance and transferring ability for disperse dyes. Under high temperature, it can promotes dyes on fabrics transfer from high concentration to low concentration, which makes fibers dyed evenly to achieve the purpose of leveling dyeing.

It can be applied in high temperature and high pressure dyeing process for fabrics and yarns of polyester fiber and polyester blends, etc.

Vat dyes

These dyes are essentially water-insoluble and contain at least two carbonyl groups (C=O) that enable the dyes to be converted by means of reduction under alkaline conditions into a corresponding water-soluble ‘leuco compound’. It is in this form that the dye is absorbed by the cellulose; following subsequent oxidation the leuco compound regenerates the parent form, the insoluble vat dye, within the fiber.

The most important natural vat dye is Indigo or Indigotin found as its glucoside, Indican, in various species of the indigo plant indigofera. Vat dyes are used where very high light- and wet-fastness properties are required.

Derivatives of indigo, mostly halogenated (especially bromo substituents) provide other vat dye classes including: indigoid and thioindigoid, anthraquinone (indanthrone, flavanthrone, pyranthone, acylaminoanthraquinone, anthrimide, dibenzathrone and carbazole).
