Sodium lignosulphonate used as dispersing Agent
Mainly used in disperse dye and vat dye dispersion and fill, Has good grinding effect, dispersion, good thermal stability, high temperature dispersion stability, contamination of the fibers is light, small reduction of azo dyes, without phosphorus, formaldehyde-free, no APEO, quinoline and biodegradable. can be used as acidic, reactive dye filling agent.
Method of Use:
When making dispersant used, according to the processing of the original dye strength, determine the ratio of dye and dispersant, determine the dosage of dispersants, add half of the first sodium lignosulfonate dispersant with dye mill, reach the finish line, to join the other dispersant,this will be work well than all dispersant grinding at once.
Used as filling agent, dye can be added before the spray dry, also can be standardization in dye after spray dried. for different types of dyes, the same dye varieties of different manufacturers, it’s best to do experiments to determine the appropriate dosage of dispersants.
Storage and Packing:
Multi-layer kraft paper bags, 25 kg/bag or tons of bag, ventilated, dry condition, save for 6 months to 2 years.
