Specification :

HH-3S can increase the acid dyeing of wool wash fastness. After treatment color, feel and luster fabric does not change.
Characters:
1.HH-3S is a heterocyclic compound, transparent acidic fluid.
2. The following dyes (acid dyes, halogen dyes, chromium metal dyes) processing of wool with the HH-3S can improve the washing process of the various fastness.
Features:
1. HH-3S nature of the superior, it is different from its acidic fixing agent of his. Therefore, it does not reduce the gloss of fabric, color fastness and friction fastness, solid-color does not affect the fabric or yarn, after the shade.
2. HH-3S easy to clean.
Usage:
1. General approach
HH-3S will be diluted with water to set the value, in the 50-60 ¡ã C processing temperature of 15-20 minutes.
Consumption decisions by the color and fabric, usually about 2-5% OWF.
2. Other methods
Load 2-5% aq. HH-3S's solution at 50 ¡ã C temperature, 3-5 minutes after treatment, the fabric through the rolling axis would be very effective. I rolled the rate of 70-80%. Then, in 70-80 ¡ã C drying temperatures.
3. Special Applications
A. acid detergent
Acid washing liquid is recommended to improve color and increase gloss.
B. The dark brown staining nylon
When dyeing nylon, tannic acid added in the 2-5% OWF HH-3S, instead of acetic acid and formic acid, get a higher fastness.
The above process for reference purposes only hope that, in use, adjust according to the actual process.
