Nylon ribbon (high temperature) acid color fixing agent MR-B

Product advantage:

1、Improve the wet and washing fastness of pre-metallized acid dye, dyed protein fibers and fabrics and polyamine fibers.

2、The improvement of water washing firmness of nylon dyestuffs has no adverse effect on light fastness and chlorine fading resistance, and the fading resistance to chlorine water is up to 100 ppm.

3、No contamination by sticky color after treatment with tannic acid fixing agent

4、Compatible with nonionic, anionic active agents and PVC without any problem

5、When the printing and dyeing material is treated with MR-B after steaming process, The product can prevent the white part from being contaminated by dyestuff.

Product character

   Appearance：Brown liquid               Ionicity: Anion/Nonion

   Solubility: Soluble in water with any ratio

Reference dosage

1.      Dosage vary in accordance with the depth of dyestuffs applied

Light color～Medium color   0.5～1.5%

   Medium～Dark color        1.5～2.5%

2.      Color-fixing bath adjusting：

1/MR-B 1.5～2.5%(o.w.f).When PH value of MR-B  is 4.5±0.3, Then no need to use acetic acid to adjust PH value。

  2/When application amount of MR-B is under 1%(o.w.f), Then add a few acetic acid or formic acid to adjust the PH value to 4.5±0.3

    Fixing temperature:  70～85℃. Fixation time:  20～30min

3.   When fixing color, High - depth acid is prevented from directly contacting with thefixing agent to avoid color stain and color spots due to condensation , and thedye - fixing agent needs to be individually diluted and put into the dye vat when in use

4. Many printing factories pursue improvement for wet fastness with acid fixing agent after dyeing applied. At present and those factory seek engineering rationalization and shorten the time of work to adopt wet-on-wet method at every processing procedure, However, much color defect, Say, Color stain, color sport and color shading take place when final inspection of finished fabric, Stripping for defective color is a dispensable procedure to get stripped and re-dyed to avert such defectiveness Different kinds of acid color

fixing agents have different stripping methods for defective color,
