Acrylic Printing Thickener

(EM-628)

General Description:

EM-628 thickener is an anionic acrylic polymer, serving as coloring carrier in fabric printing with dispersive dyes on polyester or polyester blended fabrics. Usually, it can take the place of other kinds of dispersive thickener, like sodium alginate. 

 Technique Data:

     Appearance               Solid Content     Viscosity of Original     PH value(25°C)

Yellowish To Milky Mucus      36% ±2%      6000~8000m.Pa.s     6~7

 Concentration:

1. Initial viscosity of white paste after adding water will be 70000-80000mPa.s under Brookfield rotary viscometer spindle 4#, 6RPM.

2. light color 4-5%, middle and dark color 6-8%, viscosity can be around 50000mPa.s under Brookfield rotary viscometer spindle 4, 6RPM, suitable for printing.

 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 thickener 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 this thickener has good color yield, sharp definition. Even under special situation, the paste won’t spray out.

6. Economical to use. Compared to sodium alginate, acrylic printing thickener is much more cheaper,which largely reduces processing cost.

7. Easy wash-off, hence gain soft hand feeling.

Usage

    1. Measure certain dosage of 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 thickener, while mixture is stirred with high-speed emulsion centrifuge, until it reaches required consistency.

    3. Dispersed dyestuff paste formula for reference
