High concentrated reactive printing thickener 8802 is blend of acrylic polymer and natural thickener, ECO friendly, no formaldehyde and APEO-free. It has high penetration property and give high colour yield, high resistance to electrolyte,can replace sodium alginate completely,easily using. Suitable for the printing of cotton,rayon, Ny/C fabric with flat screen printing ,rotary screen printing process.
Characteristics and advantage:
r Rapid thickening, easy operation;
r High resistance to electrolyte, lower dosage;
r Give high colour yield, brilliance colour, especially for bright shade, can save dosage of dyestuff;
r Good permeability and uniformity of the printing paste in high speeds;
r Superior storage stability in terms of printing paste form;
r Excellent penetration property, especially suitable for rayon printing;
r Can combine with other thickeners (sodium alginate, modified starch,modified cellulose and so on), in order to meet the individualization requirement of customer;
r Suitable for different printing machine.
Basic Properties:
Appearance: milky viscosity liquid
pH value:5-7(original liquid)
Ionic character: anionic
Printing process:
Paste preparation→printing→dry →steaming fixation(102-103℃,8-12min)→washing→soaping→neutralization→dry→curing.
Printing paste formulation:
Reactive dye Xg
Urea 30-200 g
Oxidizing agent 5-10 g
Sodium bicarbonate 10-30 g
Thickener8802 20-40 g(stirring 15-22min until fully dissolved)
Antifoam agent 2-5g
water Y g
Total 1000 g
Paste preparation:
1. Stock paste preparation :add 70-80% of the total amount of water first, then add the alkali and stirred until fully dissolved. Antifoam agent and oxidizing agent are then added,followed by urea.when these are fully dissolved, 8802 thickener is introduced and the stock stirred, add residual water after the viscosity meet the requirement, continuous using a shear mixer for 15-25 minutes, to dissolved thoroughly to allow the full viscosity to develop.
2. Paste preparation: reactive dyes are then added to the stock as required,after stirring to ensure complete distribution of color , the viscosity can be adjusted if required with further addition of thickener, the paste should be stirred thoroughly before printing.
Package& Storage:
120kg per plastic drum.
Stable for 6 months at 5~40 ℃ in closed containers, not affected by freezing ,summer sun exposure should be prevented.
Notes:
1.Can not be used with cationic agents together.
