Textile Finishing & Print Paste

1

Compatible by design

Partial hydrolysis keeps 1588 tolerant of the ionic and non-ionic auxiliaries normally found in a finishing bath.

2

Adjusts paste rheology

With sodium alginate it modifies print paste flow without changing colour yield.

3

Add in two passes

For stiff finishes, add half the polymer, adjust pH, then add the rest — single-shot addition risks gel particles.

Processing Guidelines

Make-down. Disperse in room-temperature water first, then raise to 70–80 °C to finish dissolution. Typical solution strength is 5–10%. Always add flake into water, never water onto flake, and filter through 60–80 mesh. Strong alkali will cut viscosity — keep pH below 9 unless the formula calls for it.
Concentration. Work at the strength the application needs — adding water later to a gelled batch does not restore the film.
Filtration. Screen the solution before it reaches the machine; gel particles that pass are defects that cannot be removed downstream.
