Acid releasing Agent HT-2143 CAS NO.629-15-2

Brief information

-- Applied to dyeing of wool and chinlon with acid dyes, mordant dyes or metal complex dyes. Can change the pH value of bath slips from neutral to acid.

Main composition

-- Organic mixed acids.

General properties

-- Appearance:    colorless transparent liquid

-- Ionicity:        nonionic

-- pH (1% dilution solution):    6-7

-- Solubility:  soluble in any proportion of water, should be used once diluted. If the dyeing bath circulation is good, can be directly added.

-- Stability:    stable to hard water, salt, acid, alkali is easy to dissolve with water.

-- Compatibility:    good compatibility with anion, cations and non-ionic auxiliaries.

-- Foaming:    none

Properties and fields of application

-- The acid releasing agent is a kind of gradient-acid, and the pH value is not decreased immediately as the normal free acid after adding into the dye bath, but with the increasing of temperature, organic acids are released gradually, and makes the pH value of dyeing bath gradually reduced to a stable level, which meets the requirements of the dyeing bath.

-- When wool and chinlon fabrics are dyed with acid dyes, reactive dyes, mordant dyes or metal complex dyes, the initial dyeing bath is neutral to weak alkaline, the initial dyeing rate is low and the dyeing is uniform. Then the dyeing bath becomes acid gradually with the increase of temperature, which can promote the dye dyeing completely and ensure the best dyeing reproducibility.

-- Because of the low initial dyeing rate and good leveling, so can increase the temperature quickly, to shorten the dyeing time and improve the dyeing efficiency.

-- Can be added at high temperature, unlike the normal free acid with the problem of uneven color flower which caused by uneven spread, uneven pH, our acid release agent can first diffuse, then release acid, so that the pH of the dye bath decreased evenly, as well as dye evenly.

-- Acid release agent is especially suitable for dyed of chinlon and chlorinated mercerized wool.
