Dispersion Printing Thickener(EM-628) 

1)General Description 

    EM-628 printing thickener is a kind of acrylic polymer in viscous liquid, serving as printing carrier in dispersion printing on textiles. Usually, EM-628 can take the place of other kinds of dispersion thickener, like sodium alginate.

2) Technique Data

     Appearance            Solid content      Viscosity          PH value(25°C)

yellowish viscous emulsion     36±2%    100.000-150.000 mpas     6~7

 

Thickening capability

a. Mix with water 3% dosage of EM-628,rotary viscosity will be lower than 22pa.s.

b. Mix with 0.4M(About 3.36% dosage)NaHCO₃ aqueous solution: 6% dosage of EM-628, rotary viscosity will be higher than 5pa.s.

3) Property and features

    1. Viscous liquid, easy to take out or mix with other auxiliaries.

2. Printing paste is easy to make, it can be ready in a while after high-speed stirring.

3. Post-thickening function allows extra dosage even in case the printing paste is not viscous enough. Add some EM618 when stirring to adjust the consistency of printing paste.

4. The performance of prepared printing paste is very stable, there is no problem to use the rest of paste next time.

5. Printing paste complemented by EM-628 has good color yield, sharp definition. Even under special situation, the paste won’t spray out.

6. Economical to use. Compared to sodium alginate, EM-628 is much more cheaper,which largely reduces processing cost.

7. To enhance color depth in loop ager for disperse prints. soft hand feeling.

4) Usage

    1. Measure certain dosage of EM-628 thickener, add specified dosage of water, and stir the mixture with high-speed emulsion centrifuge. Paste will be shaped in a few minutes.

2. Mix dyestuff and water together. Add EM-618 thickener, while mixture is stirred with high-speed emulsion centrifuge, until it reaches required consistency.
