Steamer describes the advantages of Mika Fex Reactive Dyes. MEGA Ficks BPS dyes are highly reactive dyes with mixed bi-reactive groups in a mixed form at 102-105 ° C under saturated steam and weakly alkaline media. It can form a covalent bond with cellulose molecules to achieve fixation.

Its advantages include:
- high solubility, suitable for dusting pulping process;
- strong compatibility and high reproducibility of printing;
- bright color, clear outline of printed pattern, good permeability;
- high fixing rate, less floating color and excellent printing depth;
- low affinity, the floating dye is easy to wash, and the white stain is less;
- Environmentally friendly and in line with the EU's Oeko-Tex100 ecological standard for textiles.
Prepress fabric semi-finished product
The pre-press fabric semi-finished products should generally be scoured and bleached. The fabric should be free of residual oxides, alkalis or other impurities, and the fabric surface effect is uniform.
Mejia Fex BPS has very good compatibility with sodium alginate or alginic acid ester, and the color paste thus obtained has high color yield, soft hand feeling and good printing effect. It is also fully suitable for mixed paste systems of semi-emulsified pastes or synthetic thickening pastes and their sodium alginate. If starch and its derivatives are used, it may result in a lighter color.
Attachment: Configuration of sodium alginate (or alginate) original paste:
1 formula
Sodium alginate (dry powder) 50-80
Sodium hexametaphosphate 5-10
Water X
Synthesis 1000
2 operation
Put the warm water into the bucket first, add sodium hexametaphosphate, slowly pour the dry powder of sodium alginate into the warm water with constant stirring, stir well until no granules, then add to the total amount and stir until transparent Then, the pH is adjusted to neutral with soda ash or acetic acid, and cooled for internal use.
Dye dissolution
1 warm water dissolution method:
First, use a small amount of cold water to adjust the dye into a slurry, then add the previously dissolved urea and anti-staining salt S, and then add 70-80 ° C warm water to fully dissolve the dye (do not add boiling water directly into the dye). Then, the dye was dissolved and filtered using a high-density mesh, and then added to the original paste and thoroughly stirred.
2 dusting method:
First place the original paste in the bucket, then gently pour the dye into the bucket, add urea, stir with a blender for 5-6 minutes, pour the dissolved salt solution S, and stir for 1-2 minutes. After that, the color paste was filtered with a filter cloth and set aside.
The addition of baking soda: baking soda should be added to the printing paste before it is formed into a solution and filtered.
printing
A one-phase printing process is recommended:
Printing paste formula:
Dye X
Urea 50-100
Anti-staining salt S 10
Baking soda 12-25
